History Characters / HonkaiStarRailHertaSpaceStation

* BunnyEarsLawyer: The Station's employees tend to be as quirky as they are brilliant. For instance, Hosea Lazaro was a researcher in Galactic Geopolitics and a former Astral Express crew who developed a number of Curios and inventions like the once-popular Kapo-Kali softdrink, before blasting off into Aeons-know-where when he got sick of the place, leaving a gaping hole in the Station. Even the normally sensible and wise Asta is MoneyDumb due to having her financial sense skewed by her family's ludicrous wealth, forcing Arlan to hold onto her encryption key lest she make any more wasteful purchase.

* SingleBiomePlanet: The Blue, The planet the station orbits, is mostly ocean.

** Her Technique also has a form of this [[SituationalSword when in the Simulated Universe]], granting the active party member the ability to [[AntiArmor deplete Toughness when entering combat regardless of type]]. Any Weakness Break inflicted this way will trigger debuffs related to the attacker's damage type, and Ruan Mei will deal additional damage equal to 100% of her Ice Break DMG. The toughness depletion increases by 100% per Blessings on hand,
to a maximum of twenty (i.e 2000%, enough to break most bosses' Toughness Gauge in one hit).

* CastFromHitPoints: His Skill consumes his HP (worth 15% of its maximum value, stopping if his HP falls to 1) in lieu of Skill Points.[[note]]With damage worth 120–300% of his Attack stat[[/note]]

* MythologyGag: He shares numerous similarities with Cyno from ''VideoGame/GenshinImpact'', being young men working as security officers for powerful research institutes, sporting medium height, dark skin, light hair, red eyes, and lightning-elemental powers, as well as being associated with canines.

* UpgradeArtifact: By getting her Eidolons, you can upgrade his third and fifth Eidolon Resonances, ''Power Through'' and ''Hammer and Tongs'', which will add two levels to his Skill and one to Basic Attack (''Lightning Rush'') with the former, and two to his Ultimate and Talent with the latter.

* TheChessmaster: Asta is more cunning and attentive than she makes herself out to be. In several Adventure and Companion Quests, she asks the Trailblazer for help investigating an issue, only for her to have already figured it out beforehand, only needing the Trailblazer to set the dominoes in motion with as little direct involvement as possible.
** In her Companion Mission, a user by the handle "You Already Know Me" invites the Trailblazer to an anonymous group chat spreading rumors of Asta's mishandling of the Station's funds. Once the Trailblazer decided to look into things, they keep Asta [[LockedOutOfTheLoop unaware]], reasoning that she has enough on her plate. By the end, [[spoiler:once the Trailblazer dispels said rumors, "You Already Know Me" thanks the Trailblazer for their help and implies that their actions have been in line with their plans from the start. When asked about their identity, they dodge the question and post a sticker of Asta[[labelnote:note]]With the exception of the Trailblazer, characters will only ever use stickers of themselves or Pom-Pom when texting[[/labelnote]] before the group chat is abruptly disbanded by its owner, implying that Asta was in control of the situation from the very beginning.]]

* GatheringSteam: Her Talent generates up to five charges of a 7–17.5% Attack boost to the party (hence a maximum of 35–87.5%), one at a time whenever she uses her Basic Attack or Skill, two if at least one enemy struck is weak to Fire. As the stacks are automatically reduced by three at the start of her second turn onwards, this incentivizes players to keep using her Skill despite its random damage range. Most of her upgrades are also tied to the stacks--her sixth-ascension Bonus Ability, ''Constellation'', boosts her Defense by 6% per stack (hence a maximum of 30%); her second Eidolon Resonance, ''Moon Speaks in Wax and Wane'', negates the next stack reduction after using her Ultimate; her fourth, ''Aurora Basks in Beauty and Bliss'', increases her Energy Regeneration by 15% if she has at least two stacks; and her sixth, ''Galaxy Dreams in Calm and Comfort'', reduces the stack reduction per turn to two.

* UnclePennybags: Given her vast allowance, Asta tries to help cover the costs of repairing the Station by buying replacements and extra supplies to make life better for the staff. Arlan has to prevent her from going overboard and buying needless things like an entire starnought fleet.
* UpgradeArtifact: By getting her Eidolons, you can upgrade her third and fifth Eidolon Resonances, ''Meteor Showers for Wish and Want'' and ''Nebula Secludes in Cold Cosmos'', which will add two levels to her Skill and Talent with the former, and two to her Ultimate and one to Basic Attack with the latter.

* CripplingOverspecialization: Herta is a monster during mob encounters with her multi-hit Skill, Ultimate, and Talent (the latter triggered whenever her allies reduce an enemy's HP below half)--emphasis on "HP below half," as once you pit her against damage sponges such as bosses, her performance suffers, with both her Basic Attack and Skill having the same BreakMeter damage output. Even when she triggers her Talent, it does negligible damage because she can only spin once. It's at least downplayed against {{Flunky Boss}}es such as Silvermane Lieutenants, the Abundant Ebon Deer, and the Swarm: True Sting; with their flunkies around, there will be more chances of Herta using her follow-up attacks and deal some extra damage to the boss, even if not by a whole lot. Herta is also a fantastic choice in Pure Fiction, which involves fighting waves of weaker enemies that give her Talent plenty of chances to trigger.

* MeanBoss: Downplayed, as Herta is never openly abusive towards her personnel, and she never makes any outward threats to reduce their payments or fire them, but she is generally loath to take responsibility for overseeing their work and doesn't really care about their wellbeing, [[SkewedPriorities valuing her own interests and experiments above all else]]. This on top of being an InsufferableGenius means she's hard to approach, especially Arlan, who has to constantly deal with her because she keeps unloading tasks unto him that typically fall beyond the Security Department's purview.

* ThisLooksLikeAJobForAquaman: Herta's value is usually negligible against bosses, since her kit revolves around having lots of low-level foes to swiftly dispatch with her wide-ranging attacks. The Abundant Ebon Deer, however, seems almost tailor-designed for her, given that its habit of periodically summoning waves of saplings to hinder your offense and eventually overwhelm you with its action economy becomes a liability when faced with Herta's crowd-control kit; compounded with its innate weakness to Ice damage, this ensures Herta can spam her Talent ''ad infinitum''.

* UpgradeArtifact: By getting her Eidolons, you can upgrade her third and fifth Eidolon Resonances, ''That's the Kind of Girl I Am'' and ''Cuss Big or Cuss Nothing'', which will add two levels to her Skill and one to her Basic Attack (''What Are You Looking At?'') with the former, and two to her Ultimate and Talent with the latter.

Ruan Mei enhances her allies' ability to severely compromise their foes with strums of her mystical stringed instrument. Her Skill, ''String Sings Slow Swirls'', puts the party in the "Overtone" state for three turns, increasing their damage output and Weakness Break Efficiency, while her Ultimate, ''Petals to Stream, Repose in Dream'', creates a mystical field that for two turns enhances the party's Resistance Penetration and allows all their attacks to mark foes with Thanatoplum Reblooms that explode whenever they are about to recover from Break, delaying their next turn. In addition, her Talent, ''Somatotypical Helix'', boosts her allies' Speed and adds an extra hit to their attacks whenever they Break enemies. Furthermore, her Technique, ''Silken Serenade'', puts her in the same-named state that automatically triggers her Skill at the start of battle with a negated SP cost; in the Simulated Universe, it has an additional effect where attacking enemies will cut into their Toughness Gauges regardless of resistances as well as immediately triggers their type's associated debuffs and deal additional damage if they Break foes in such a manner, with increasing Toughness damage proportional to the number of Blessings accrued beforehand.[[note]]When fully upgraded, she regenerates Energy whenever her turn comes up as well as gains a Break Effect boost for three turns whenever enemies are Broken; the party gains heightened Attack against Broken enemies while she is active; and her Ultimate now lasts three turns.[[/note]]

* ArmorPiercingAttack: Her Ultimate deploys a field which boosts all of the the party's Resistance Penetration stats by 15–27% for two turns. In addition, her first Eidolon Resonance, ''Neuronic Embroidery'', gives the field the ablity to allow the party's attacks to ignore 30% of their enemies' Defense stats, while her sixth, ''Sash Cascade'', extends the field's duration to three turns (and increases her Talent's Break Damage by 200%).

* TheHermit: Ruan Mei used to live with her family on a planet known as "No Man's Land" which doesn't exactly inspire constant human interaction outside immediate folks. After losing her family and meeting Nous, she secluded herself. Even initial attempts at inducting her to the Genius Society failed as she'd simply dispose of their letters, and even now she carries on her research with little to no interaction with others.

* KickThemWhileTheyAreDown: Ruan Mei specializes in making it far easier to Break enemies and dishing out further punishment.
** Her Skill bestows the Overtone effect which, for three turns, boosts the party's damage output by 16–35.2% and [[AntiArmor Weakness Break Efficiency]] by 50%, helped along by her Talent bestowing a granting an 8–10.4% Speed buff to every ally but herself as well as augmenting their attacks (including hers) with an explosive icy flower whenever they Break enemies.[[note]]With damage worth 60–132% of her Ice Break Damage.[[/note]]

** Her Technique also has a form of this when in the Simulated Universe, granting the active party member the ability to [[AntiArmor deplete Toughness when entering combat regardless of type]]. Any Weakness Break inflicted this way will trigger debuffs related to the attacker's damage type, and Ruan Mei will deal additional damage that increases in potency proportional to the number of the party's Blessings to a maximum of twenty (at a rate of 100% per Blessing, hence a maximum of 2,000%).

* SituationalSword: Her Technique becomes exponentially more powerful in Simulated Universe, making their field attacks deplete enemy Toughness regardless of resistances and scaling such proportional to the number of their Blessings.

* UpgradeArtifact: By getting her Eidolons, you can upgrade her third and fifth Eidolon Resonances, ''Viridescent Pirouette'' and ''Languid Barrette'', which will add two levels to her Ultimate and Talent with the former, and two levels to her Skill and one to Basic Attack (''Threading Fragrance'') with the latter.

Ruan Mei excels at enhancing her allies' ability to severely compromise their foes with strums of her mystical stringed instrument, through her Skill, ''String Sings Slow Swirls'', which puts the party in the "Overtone" state for three turns that increases their damage output and Weakness Break Efficiency, and her Ultimate, ''Petals to Stream, Repose in Dream'', which creates a mystical field that for two turns enhances the party's Resistance Penetration and allows all their attacks to mark foes with the Thanatoplum Reblooms that explode whenever they are about to recover from Break, delaying their next turn. In addition, her Talent, ''Somatotypical Helix'', boosts her allies' Speed and adds an extra hit to their attacks based on her Break Effect whenever they break enemies. Furthermore, her Technique, ''Silken Serenade'', puts her in the same-named state that automatically triggers her Skill at the start of battle with a negated SP cost; in the Simulated Universe, it has an additional effect where actively attacking enemies will cut into their Toughness gauges at the start of battle regardless of type resistances as well as immediately trigger their type's associated debuffs and deal additional damage based on her Break Effect if they Break foes in such a manner, with increasing Toughness damage proportional to the number of Blessings accrued beforehand. [[note]]When fully upgraded, she regenerates Energy whenever her turn comes up as well as gains a Break Effect boost for three turns whenever enemies are Broken; the party gains heightened Attack against Broken enemies while she is active; her Skill gains a further damage boost for the party proportionate to her Break Effect above a certain threshold; and her Ultimate now lasts three turns as well as allows her allies' attacks to ignore a fraction of their enemies' Defense.[[/note]]

* ArmorPiercingAttack: Her Ultimate deploys a field which boosts the party's All-Type Resistance Penetration for two turns.[[note]]Depending on Trace levels, by 15–27%[[/note]] In addition, her first Eidolon Resonance, ''Neuronic Embroidery'', allows the field to let the party ignore 30% of their target's Defense stat, while her sixth, ''Sash Cascade'', extends the field's duration to three turns (and increases her Talent's Break Damage by 200%).

* FlowerMotifs: Plum blossoms. [[MeaningfulName The name "Mei" means "plum" in Chinese.]] She mentions them often, either referring to the fruit or flower with concerns to desserts, scents, or comparing her observations to them. Her outfit also has them, with two pinned to her hip and the small of her back, and on her shawl. In Chinese floriography, they can mean "perseverance in adversity" as they're known for being capable of blooming even in harsh winter, fitting for a tireless scientist with ice powers who plumbs the secrets of life and may have [[GodhoodSeeker aspirations for godhood.]]

* GodhoodSeeker: Ruan Mei's Character Trailer implies that she seeks to become an Aeon or an Emanator, so she can ''truly'' research the deepest questions of biology and evolution.
* TheHermit: Ruan Mei used to live with her family on a planet known as "No Man's Land" which doesn't exactly inspire constant human interaction outside immediate folks. After losing her family and meeting Nous, she secluded herself into a very solitary lifestyle. Even initial attempts at inducting her to the Genius Society failed at first as she'd simply dispose of their letters, and still now she carries on her research with little to no interaction with others.

** Her Skill bestows the Overtone effect which, for three turns, boosts their damage output and increases the party's [[AntiArmor Weakness Break Efficiency]] by 50%, helped along by her Talent granting additional Speed to every ally but herself as well as augmenting their attacks (including hers) with an explosive icy flower whenever they Break enemies.[[note]]Depending on Trace levels, her Skill boosts damage by 16–35.2%, while her Talent boosts Speed by 8–10.4%, and its extra hit deals damage equivalent to 60–132% of her Ice Break Damage.[[/note]]
** Her Ultimate deploys a field that boosts the party's Type Resistance Penetration and allows all their attacks to inflict Thanatoplum Reblooms, which explode whenever affected enemies are about to recover from Break, dealing additional Break damage and significantly delaying their next turn.[[note]]Depending on Trace levels, it boosts the party's Type Resistance Penetration by 15–27%, its additional damage is worth 30–54% of Ruan Mei's Ice Break Damage, and the turn delay is equivalent to 20% of Ruan Mei's Break Effect stat plus 10%[[/note]] After Thanatopium Rebloom's effect is triggered on an enemy, said enemy cannot be inflicted with the status again until they fully recover their Toughness Gauge.
** Her Technique also has a form of this when in the Simulated Universe, granting the active party member the ability to [[AntiArmor deplete Toughness when entering combat regardless of type]]. Any Weakness Break inflicted this way will trigger debuffs related to the attacker's damage type, and Ruan Mei will deal additional damage equal to 100% of her Ice Break Damage. Said reduction also scales up with the number of Blessings currently in possession, increasing by 100% per Blessing, to a maximum of 20 Blessings (hence 2,000%).

** Her second Eidolon Resonance, ''Reedside Promenade'', bestows a 40% Attack boost for allies whenever they target Broken enemies, while her fourth, ''Chatoyant Éclat'', boosts Ruan Mei's Break Effect by 100% for three turns whenever an enemy is Broken (not necessarily by her alone).
* LackOfEmpathy: She sees no issue in drugging the Trailblazer to prevent them from speaking anything about her and sending them to fix her mistakes (i.e. [[spoiler: a failed clone of Tayzzynroth's Emanator that she created in the first place]]). When the Trailblazer confronts her about the latter, she doesn't appear to be concerned for their wellbeing, and her prior talk about "compensation" is never brought up again. She also has difficulty showing her creations any sort of affection, claiming [[WhatIsThisThingYouCallLove she doesn't understand love]].

* NoSocialSkills: Very much like her fellow Genius Society members, Ruan Mei spent most of her time on her research rather than learning how to interact with other people. When she visits Herta Space Station, she doesn't even bother announcing her arrival, so most of the staff weren't aware she is already onboard. She also remains cold and distant from her creations, who love her unconditionally and crave her attention and approval. She even admits to the Trailblazer that she's often at a loss at how to deal with other people, leading her to just avoid social interactions and attachments altogether.

* RareRandomDrop: She can appear in the Simulated Universe as an Occurrence event, but she is easily among the rarest, if not ''the'' rarest event out there. And for good reason, as encountering her gives you a choice between obtaining ''all'' Blessings of a certain Path, or a massive 2000 Cosmic Fragments. A 2nd version of her encounter gives you the choice between enhancing all of your current Blessings or ten random Curios, or (in Swarm Disaster) 10 "cheat" chances to guarantee the chances of your "Path Dice" roll. And if you have Ruan Mei in your party when getting this event, you can pick to get '''all''' of the rewards simultaneously.

* SituationalSword: Ruan Mei's Technique becomes exponentially more powerful in Simulated Universe, making any ally field attack deplete enemy Toughness as if you attacked their Weakness and scaling the damage of their field attack based on how many Blessings the user has, up to 20.
* StatusBuff: Her Skill buffs the whole party's damage output. Her sixth-ascension Bonus Ability, ''Candle Lights on Still Waters'', also gives the skill the ability to give the party an additional 6% damage boost for every 10% of her Break Effect stat above 120% (to a maximum boost of 36%, meaning it will max out if her aforementioned stat is at least 180%).

Herta reins in crowds of enemies with her giant mallet through her Skill, ''One-Time Offer'', which increases in potency if her foes have at least half their HP remaining; her Talent, ''Fine, I'll Do It Myself'', which is triggered whenever she or her allies drop at least one foe's HP to below half; or her Ultimate, ''It's Magic, I Added Some Magic'', where she conjures a giant gemstone which she slams down onto them. In addition, her Technique, ''It Can Still Be Optimized'', boosts her Attack for the first three turns of battle.[[note]]When fully upgraded, her Basic Attack gains an extra hit should her target have no more than half their HP; her Ultimate deals more damage to Frozen foes, as well as boosts her Attack for her next turn; and her Talent can now boost her Critical Rate up to five times whenever it is triggered.[[/note]]

* BattleCry: "Time to twirl!" or "Kuru kuru" (meaning "spin") in Japanese, which has already become memetic as of the second closed beta due to the sheer frequency this line is heard by players. Her passive triggers whenever an enemy falls below 50% HP, which causes her to launch a SpinAttack during which she says this line.

* CripplingOverspecialization: Herta is an absolute monster during regular mob encounters with her multi-hit Skill, Ultimate, and Talent (the latter triggered whenever her allies reduce an enemy's HP below half)--emphasis on "HP below half," as once you put her up against damage sponges such as bosses, her performance drops hard and she struggles to do decent damage, with both her Basic Attack and Skill having the same BreakMeter damage output. Even when she triggers her Talent, it does negligible damage because she can only spin once. It's at least downplayed against {{Flunky Boss}}es such as Silvermane Lieutenants, the Abundant Ebon Deer, and the Swarm: True Sting; with their flunkies around, there will be more chances of Herta using her follow-up attacks and deal some extra damage to the boss, even if not by a whole lot. Herta is also a fantastic choice in Pure Fiction battles, which involves fighting waves of weaker enemies that give her Talent plenty of chances to trigger.

** Herta's second Eidolon Resonance, ''Keep the Ball Rolling'', boosts her Critical Rate by 3%, which can stack up to five times (equivalent to 15%) whenever she triggers her Talent.

* EverybodyHasStandards:
** Despite her lack of concern for morality and ethics, even Herta is unwilling to work with Dr. Primitive, a fellow Genius Society member, since his wanted status with the IPC and Galaxy Rangers would cause too many headaches for her.

** In the 1.6 Livestream, Herta makes no secret how much she dislikes Dr. Ratio. She openly and angrily admonishes how rude he can be when teaching, often bringing his students to tears and leaving them an emotional wreck.
* GemstoneAssault: Her Ultimate fires a giant cat head-shaped diamond which she slams down onto enemies with her mallet. For the sake of gameplay consistency, its damage still counts as Ice damage because, not only is there no [[DishingOutDirt Earth]] element in the ''Star Rail'' universe, but characters are always set to one element.

* {{Hypocrite}}: She openly dislikes Dr. Ratio, partially due to his massive ego- which is rich coming from someone who has an egotistic streak herself.

** Her Talent automatically triggers a SpinAttack that hits all enemies whenever any of her allies' attacks drop a foe's HP below half, [[OutOfTurnInteraction interrupting the action order whenever it's triggered]].[[note]]Depending on Trace levels, damage is equivalent to 25–47.5% of Herta's Attack stat[[/note]] If more than one foe have their health drop below half at the same time, Herta will spin more times at once, equal to said number of enemies. Relatedly, her fourth Eidolon Resonance, ''Hit Where It Hurts'' increases the Talent's damage by 10%.
** Her first Eidolon Resonance, ''Kick You While You're Down'', boosts the damage of her Basic Attack ''What Are You Looking At?'' by 40% of her Attack stat whenever her target has no more than half their HP, which helps improve her otherwise mediocre single-target damage.
** Inverted with her Skill, which deals 20% extra damage if her enemy's HP is over half. In addition, her second-ascension Bonus Ability, ''Efficiency'', raises said extra damage by 25%.

* MeanBoss: Downplayed, as Herta is never outright abusive towards her personnel, and she never makes any outward threats to reduce their payments or fire them, but she is generally loath to take responsibility for overseeing their work and doesn't really care about their wellbeing, [[SkewedPriorities valuing her own interests and experiments above all else]]. This on top of being an InsufferableGenius means she's hard to approach, especially Arlan, who has to constantly deal with her because she keeps unloading tasks unto him that typically fall beyond the Security Department's purview.

* MoneyDumb: In Topaz's promotional trailer, "Expert Tutorial", Herta gets her account frozen for overcharging, leading Topaz to come to collect the dues. While no numbers are given, the enormous bell curve and [[Fiction500 Asta's]] horrified reaction imply that Herta spent a truly astronomical amount of money. Considering that Asta thinks 200 million credits is pocket change, one has to wonder what Herta did to accrue such a tab.

* PetTheDog: She may be an apathetic InsufferableGenius most of the time, but Herta ''is'' capable of some kindness from time to time, with a strong implication that her respect and kindness has to be earned. In particular, [[spoiler:she holds great respect for Chadwick, the 79th member of the Society, and the lengths he went to keep the knowledge of the Imaginary Implosion Pulse away from the IPC, and later honors his LastRequest to safeguard the information he entrusts to her far away from the IPC's grasp.]]

* SlidingScaleOfGameplayAndStoryIntegration: Herta is a InsufferableGenius and AbsentMindedProfessor who starts and drops projects at a whim, and even if something holds her interest (like the Trailblazer in the prologue's NonStandardGameOver) she eventually moves on to other things regardless. As a playable unit, she ''excels'' in handling groups of common enemies, but [[CripplingOverspecialization struggles with her lack of staying power against bosses.]]

* ThisLooksLikeAJobForAquaman: Herta's value as a unit is usually dismissed when it comes to bosses, since her kit revolves around having lots of low-level foes to swiftly dispatch with her wide-ranging attacks. The Abundant Ebon Deer, however, seems almost tailor-designed for her, given that its habit of periodically summoning waves of saplings to hinder your offense and eventually overwhelm you with its action economy becomes a liability when faced with Herta's crowd-control kit; compounded with its innate weakness to Ice damage, this ensures Herta can spam her Talent ''ad infinitum''.

* CastFromHitPoints: His Skill consumes his HP (worth 15% of its maximum value, stopping if his HP falls to 1) in lieu of Skill Points.[[note]]With damage work 120–300% of his Attack stat[[/note]]

* AnonymousBenefactor: A downplayed example for the Herta Space Station. Most of the facilities are mostly funded by Asta's personal bank account, without whose support work on the Station would be much harder. The main reason why she is anonymous is because neither she nor Arlan want to make a big deal out of it and nobody believes that Asta can be ''that'' rich.
* BadassAdorable: Asta is a beautiful, [[NiceGirl kindhearted]] [[{{Ojou}} young heiress]] who nevertheless can hold her own in a fight and [[TheChessmaster is considerably more cunning than she lets herself on]].

** Especially compared to the whimsical and often-absent Herta. Most of her expenditures go to the Station, she monitors the wellbeing of the staff and is lenient on them because she knows staying on a space station can be mentally taxing, and Arlan has nothing but praise for her.
** PlayedForLaughs in Arlan's Companion Mission, in which she concludes from spotty evidence that Arlan has come to hate her. Asta is hysterical and profusely apologizes to a baffled Arlan while completely refusing all of his attempts to make her feel better. It's not until she runs out of "evidence" to present that he's able to explain that his "trials" for managing an overbearing boss are because of Herta, who assigns him things so far out of his job description that he doesn't know how to handle them.

* CastingGag: Creator/FeleciaAngelle, Asta's English voice actress, also did Mona Megistus of ''VideoGame/GenshinImpact'', both young women with an expertise in studying the stars, a spellcaster-like fighting style, and wealth offset by poor money management. Ironically, the two have opposite elements towards each other.

** In her Companion Mission, a user by the handle "You Already Know Me" invites the Trailblazer to an anonymous group chat spreading rumors of Asta's mishandling of Space Station funds. Once the Trailblazer decides to look into things, however, they decide to keep Asta [[LockedOutOfTheLoop unaware]], reasoning that she has enough on her plate. By the end, [[spoiler:once the Trailblazer dispels said rumors, "You Already Know Me" thanks the Trailblazer for their help and implies that their actions have been in line with their plans from the start. When asked about their identity, they dodge the question and post a sticker of Asta[[labelnote:note]]With the exception of the Trailblazer, characters will only ever use stickers of themselves or Pom-Pom when texting[[/labelnote]] before the group chat is abruptly disbanded by its owner, implying that Asta was in control of the situation from the very beginning.]]

* DamageOverTime: Asta's second-ascension Bonus Ability, ''Sparks'', gives her Basic Attack a base 80% chance to inflict Burn on her target for three turns.[[note]]Damage per turn is equivalent to half her Attack stat[[/note]]
* DamselInDistress: [[spoiler: Ifrit kidnaps her briefly as part of his scheme to cause chaos onboard Herta Space Station. Fortunately, the Trailblazer and Dr. Ratio rescue her.]]

* Fiction500: Asta effectively funds the entirety of the Herta Space Station off her own credit card, a feat that makes so little of a dent in it that her mother actually messages her in concern that she's not spending ''enough'' by their obscenely wealthy standards.

* GatheringSteam: Her Talent generates up to five charges of an Attack boost to the party, one at a time whenever she uses her Basic Attack or Skill, two if at least one enemy struck is weak to Fire.[[note]]Depending on Trace levels, 7–17.5% apiece, for a total of 35–87.5%[[/note]] As the stacks are automatically reduced by three at the start of her second turn onwards, this incentivizes players to keep using her Skill despite its random damage range. In addition, some upgrades are tied to the stacks--her sixth-ascension Bonus Ability, ''Constellation'', boosts her Defense by 6% per stack (hence a maximum of 30%); her second Eidolon Resonance, ''Moon Speaks in Wax and Wane'', negates the next stack reduction after using her Ultimate; her fourth, ''Aurora Basks in Beauty and Bliss'', increases her Energy Regeneration by 15% if she has at least two stacks; and her sixth, ''Galaxy Dreams in Calm and Comfort'', reduces the stack reduction per turn to two.
* HeroWithBadPublicity: While all of the Herta Station researchers HeroWorship Herta herself, the gossipers are quick to complain about upper management, and Asta in particular. In fact, it hardly takes Ifrit any work at all to make them think she would go so far as to murder her detractors.

** It doesn't matter much given she hails from an obscenely wealthy family, but Asta has a habit of simply buying things for the Space Station with her own money, whether or not they really needed them, ranging from replacements for machines they still have spares of to a whole starnought fleet for security. It can get so out-of-hand that Arlan tries to stage an intervention since her first instinct is to always buy new things and he thinks she's being irresponsible with her funds. Played with that she's well-aware that the Space Station's funds are limited, which just emboldens her to use her own money to cover the expenses.
** In the "From Xianzhou With Love" Adventure Mission, Asta tasks the Trailblazer with investigating a suspected scammer from the Xianzhou Luofu. When the Trailblazer gains direct access to said chat, she encourages them to intentionally get scammed as proof, and assures them that she will bankroll the expenses. Depending on your dialogue options, the Trailblazer can transfer as high as '''200 million credits''' on Asta's dime, to which she wonders aloud if that's a lot of money to lose in these kinds of scams.[[note]]After the mission, she does say that, following the money transfer system she's using, if she wants to transfer huge amounts of credits at once, the system will delay the transfer by a few days, which potentially allows her to cancel it.[[/note]]

* {{Ojou}}: Beautiful, graceful, and secretly but ''obscenely'' wealthy. In the Japanese dub, Arlan even attempts to call her this ''ad verbatim'' before correcting himself.
* RandomizedDamageAttack: Her Skill is launches five laser beams heavenward, the first hitting her target, the rest at random (including her target).[[note]]Depending on Trace levels, damage per hit is equivalent to 25–62.5% of Asta's Attack stat[[/note]] If used against a lone target, however, all the lasers will hit them for bigger damage and (against enemies WeakToFire) [[AntiArmor quicker Toughness Gauge reduction.]] In addition, her first Eidolon Resonance, ''Star Sings Sans Verses or Vocals'', adds a fifth random laser.
* RebelliousPrincess: Asta is not so fond of her parents, who are among the IPC's leaders, and she has been ignoring their letters for quite some time. As a child, she always wanted to be an astronomer, but her parents insist on having her partake in the family business and [[FantasyForbiddingFather dismiss her hobbies as a frivolous pursuit]]. It wasn't until Herta visited them with the intent of recruiting Asta as her lead researcher that they changed their minds and agreed to her offer out of deference for Herta's reputation, which finally gave Asta the freedom to follow her heart's desire, and even then, as she mentions in her "About Self: Work" voice line, she has to continue working hard in the Station, lest she be left with no choice but to return to her family and inherit their fortune.
* SecretlyWealthy: Her being an heiress to the IPC is not a widely known fact, so the first thought some people have when seeing her purchase history is that she's embezzling money somehow.

* SupportPartyMember: Asta largely specializes in boosting her allies, exemplified with her Ultimate, which increases the party's Speed for two turns.[[note]]Depending on Trace levels, 36–57 points[[/note]] Conversely, her offensive ability is not as potent, typically limited to her Skill (which randomly hits enemies) and her Technique (which deals damage to all enemies at the start of battle, equivalent to half of Asta's Attack stat).
* SuspiciousSpending: {{Subverted|Trope}}. This nearly gets her in trouble in her Companion Mission. When she spends a large sum of money to buy supplies and materials to repair the space station, since Herta herself won't do it out of laziness, several staff members get suspicious, and think that she's embezzling the money. It turns out, her parents are the leaders of the [=IPC=], meaning that she really is that rich, not that she would admit it though.

* UnclePennybags: Given her vast allowance, Asta tries to help cover the costs of the damage to the Herta Space Station by buying replacements and extra supplies to make life better for the other researchers. But Arlan has to prevent her from going overboard and buying needless things like an entire starnought fleet.
