Sandbox / Villainess Level 99 Yumiella

Tropes applicable to her in all timelines

• All the Other Reindeer: In all timelines, most people, especially her classmates, are wary of Yumiella for her dark hair.
• Casting a Shadow: Yumiella possesses a rare talent for dark magic. She can cast very destructive darkness flames, black holes or control shadows.
• Elemental Hair Colors: She can exclusively use dark magic and her hair is jet-black to match the element. Also counts for Elemental Eye Colors because her eyes are black as well.

• Fantastic Racism: Thanks to the demon lord being black-haired, she's a victim of prejudice against black hair.
• Foil: The two Yumiellas are foil to each other.
  • The original Yumiella had to grow up rejected by the world, something that she never got over, while the main character reincarnated into her world with a more mature and aloof mindset to not care about that.
  • The original Yumiella was willfully weak and failed to make any friends, while the main character trained to the highest level and made some friends.
• Hime Cut: She's a Japanese girl reborn as the daughter of a noble. In her current body, she has M-shaped straight bangs, bra strap length sidelocks, and knee length straight hair. This is how the novel’s Yumiella realized she is a reincarnate: she looked at her hair and thinks it looked like the one on Japanese dolls (which frequently sport this hairstyle).
• Inconsistent Spelling: The light novel and anime translations romanize her name as Yumiella. The manga translation however uses Eumiella.
• Lady of Black Magic: She's a beautiful, aloof, and highly powerful mage specializing in dark magic.
• Light Feminine and Dark Feminine: The Dark Feminine, with both Eleanora and Alicia as the Light Feminines. Yumiella is an Aloof Dark-Haired Girl who is emotionally distant and not very interested in socializing, whilst Eleanora and Alicia are much more cheerful and sociable.
• Lonely Rich Kid: She lived in a mansion by herself her whole life, with her parents all but abandoning her due to her black hair being a sign of bad luck. She only had a few maids to take care of her, and even they were frightened by her.
• Parental Neglect: Both versions of Yumiella suffer from this, with her parents always living in the capital and leaving her alone with maids in the provincial estate. However, the one from the novels is more comfortable with this trope, due to being a loner in her past life.
• Punny Name: Her name goes in line with her specialty in powerful dark magic. Yumiella is likely derived from "yami", the Japanese word for darkness, while her family name, "Dolkness", sounds a lot like "darkness". Whether intended or not, she also is quite a dork.
• Steven Ulysses Perhero: Her entire name sounds like "Darkness" and she uses dark magic.

• World's Strongest Woman: In LMH, Yumiella is said to become an even bigger threat than the demon lord and has the highest level of the game. In the main story, it's been mentioned nobody in recorded history has levels anywhere close to hers, and in Valschein the strongest living person before her is Adolf, who is around Level 60. She's not only the strongest human being alive; she's the strongest in recorded history.

Tropes applicable to her current self

• The Ace: Yumiella is the best in academics, as well as magical and physical abilities. Excluding her social skills (or the lack thereof), there really is nothing she doesn't excel at.
• Acquired Poison Immunity: Of a sort. In the latter half of Volume 1, Yumiella is being poisoned by her own maid, Rita. However, due to her absurdly high health pool, the poison merely makes her tea taste bad.
• Action Girl: She is already level 99 when the story begins, making her leagues more powerful than everyone.
• All the Other Reindeer: In addition to her dark hair, was was also ostericized for her absurdly high level, and most especially, her talent in dark magic, at least before the King gives her a clean bill of health.
• Aloof Dark-Haired Girl: While she lacks the typical maturity, she has dark hair and acts distant towards most people.
• Benevolent Mage Ruler: Near the end of Volume 1, Yumiella deposes her parents and becomes the ruling Countess of Dolkness with the blessing of the king, as her parents tried to have her assassinated. She intends to rule her county justly to get rid of any prejudices about black-haired people and dark magic users.
• Best Her to Bed Her: Yumiella lies that she only wishes to marry someone stronger than her in hopes of discouraging suitors who wish to manipulate her. Patrick doesn't realize that this is a lie, and so he starts using the growth amulet to catch up to her. When Yumiella learns about this, she makes it clear that strength isn't actually a prerequisite by creating a loophole on the spot just for him.
• Brutal Honesty: In a bid to get Eleanora to hate her, Yumiella is incredibly blunt with her. However, this causes the opposite effect because Eleanora appreciates Yumiella's honesty because she's always surrounded by Yes Men.
• Celibate Heroine: She initially has no interest in romance and the romantic scenes of LMH bored her. She even makes up an excuse of only being willing to marry a man stronger than her to turn away possible suitors, especially due to many people planning to manipulate her by marrying her. Subverted when she falls in love with Patrick, although she still doesn't actively pursue a relationship with him because of her cluelessness towards his feelings.
• Cloudcuckoolander: Yumiella is weird, to say the least. She gets lots of odd ideas, has trouble reading the mood and expressing her emotions, and often has Skewed Priorities.

• Comically Missing the Point: Because of her atypical mindset being both an avid gamer in her previous life and limited social skills, Yumiella sometimes doesn't get the intended points of others. During her first field lesson with other students she has several moments occuring right after each other:
  • She learns from Patrick how he learned battle tactics and effective, with the shield holders up front to stop monsters while the range fighters kill monsters, and then will switch so the range fighters pin down the monsters and allow the shield holders to kill the monsters. This allows both to level up in a roughly fair process. Yumiella decides to put this into practice right away by using a monster-summoning flute to call a horde of monsters to them, rather than take the idea to the faculty and prepare the students for the attack.
  • After the wave is killed but exhausting the class, Patrick admonishes Yumiella for her actions because she threw barely trained students against hordes of monsters. Yumiella thinks he means the second part of leveling up with the ranged fighters holding down the monsters cannot be done because the mages and archers are exhausted. So she summons more monsters but this time binds them with her magic so they can be easily killed.
  • After that wave is killed, Patrick admonishes her again because there was no warning to her actions the last two times. She realizes her mistake and agrees it was in poor taste. She then tells Patrick she will be using the flute right before she blows and will repeat her method of binding the monsters so others can kill them.
• Conveniently Seated: She sits in the window seat in the last row of the classroom.
• Dark Is Not Evil: Despite being a powerful dark magic user, Yumiella at her worst is a Cloudcuckoolander lacking social skills and is otherwise rather calm and prefers to keep to herself. After seeing a boy with dark hair getting harassed, it leads to her deciding to take on a position of power so she can start changing the public perception of black hair and dark magic.

• Defeating the Undefeatable: Manages to take on the God of Evil, a nearly unstoppable deity who can take Yumiella's attacks head on without so much as a scratch, and win, though thanks to Patrick and the other gods, as well as Yumiella 2's sacrifice.
• Didn't Think This Through: When Alicia and her harem confront her in the cafeteria about her being the demon lord and her strength, on the latter she calls out the heroes for not strengthening themselves enough. She then explains her methods of level grinding to all in the cafeteria believing it will clear up any misunderstandings and motivate the heroes to work hard. But Edwin refuses to listen, and the other students are horrified by her use of an Amulet of Growth over an Amulet of Protection, using a flute to summon monsters, and to do this solo. It ends up scaring away the students who had just tried sitting with her to eat.

• Does Not Know Her Own Strength: She has trouble controlling the Super-Strength she gains from reaching level 99. As a result, she accidentally sends Patrick flying twice while sparring with him.

• Dragon Rider: Since Alicia doesn't get the dragon-slaying quest, Yumiella takes it up and gets the dragon egg instead, which ends up hatching a darkness-attribute dragon she names Ryuu.
• Dumb Jock: She is seen as this by those close to her, who, due to still having a RPG geek mindset, is mystified by her obsession with power-enhancing items and weapons when she's already the strongest person in the world.
• Eerie Pale-Skinned Brunette: Subverted, since while Yumiella inherits such a character design, she is more stoic and odd rather than eerie.
• Experienced Protagonist: After she regained her Past-Life Memories at five years old, she dedicated herself to fighting monsters and conquering dungeons to raise her level in case she needed to defeat the Demon King herself. When the story begins, she's level 99, making her the World's Strongest Woman.
• Fearless Fool: This is how people see her when she tells them she reached level 99 through Level Grinding. Going to fight monsters alone and without an Amulet of Protection is insanely reckless and dangerous, to the point most people would think only a suicidal loon would use such a method to level up.
• Gamer Chick: When she lived on Earth, Yumiella was a dedicated gamer. The RPG aspects of LMH appealed to her more than the Otome sections.
• Genius Ditz: She has more or less infinite power as far as the series is concerned and a desire to be a capable governor over her territory, but displays, uh, little apparent ability for the latter and frequently engages in behavior that puts herself and others in danger. Fortunately, Patrick exists to help keep a leash on her more dangerous ideas.
• Gone Horribly Right:
  • She starts monster killing and dungeon crawling in order to survive and help fight the Demon Lord. Her zealous pursuit ends up maxing out her levels without her realizing it and getting the fear and distrust of other classmates who now fear her not just for being black-haired.
  • When Eleanora is trying to befriend her, Yumiella gives completely honest critiques on the former's cookies not being good at all. Rather than be offended, Eleanora is happy someone is honest with her on this and further cements Eleanora being friendly to Yumiella.
• Hates Small Talk: Due to her being No Social Skills, she cannot handle small talk that does not interest her. She only gets through small-talk sessions by using scripted responses.
• Healing Hands: Yumiella is capable of casting powerful recovery magic and can even heal an arm that is cut off. It just looks very grotesque when used.
• Improbable Age: Reaching level 99 is an accomplishment that no one expected to be possible within a lifetime, therefore people are skeptical when they learn Yumiella is already level 99 at merely 15 years old.
• Insecure Love Interest: Even after she realizes she has feelings for Patrick, Yumiella sees herself as a poor match for him because her status as a reincarnated person from another world causes her to think a normal person from the game world would be better suited for Patrick.
• Introverted Cat Person: She adores cats, but notes that cats are utterly terrified of her. On the other hand, she is generally very introverted and does not like socializing much.
• Level Grinding: Yumiella achieved level 99 the honest way, over mountains of monster corpses. The light novel elaborates that she kept clearing the dungeon found within the Dolkness territory over and over again using a Growth Amulet for extra experience points and a demon-summoning flute to summon enemies to attain excellent efficiency.
• Loon with a Heart of Gold: Yumiella isn't exactly the most "mentally together" person around, but there is no doubt that she is a decent person anyway. In fact, despite her initial indifference to politics, she becomes the next Count Dolkness because she wanted to change the perceptions of black hair after witnessing others experience discrimination for black hair.
• Love Epiphany: As she spends more time around Patrick, she starts developing feelings for him, although she doesn't realize it herself at first until it hits her she hasn't left the country already because she wants to stay with Patrick.
• Mundane Utility: A flashback shows how, as a child, she summoned hands made of dark magic... in order to practice dancing.
• Muscles Are Meaningless: She's a young girl who doesn't look particularly strong, but being level 99 makes her faster, stronger, and tougher than anyone could expect from her appearance. William, a guy who is much taller and more muscular than her, gets easily sent flying by a single hit from her and she was holding back.
• Nightmare Fetishist: She thinks a dragon makes for an adorable pet. While everyone else thinks her dragon companion Ryuu is terrifying, she finds him cute.
• No Social Skills: Downplayed. Because of both her lonely childhood and her own strangeness, Yumiella has trouble connecting with others. She does understand noble etiquette from the various lessons she was given as a child, and can convincingly pretend to follow a conversation she isn't interested in, but once she is outside of those situations, she has trouble understanding people's reactions. This trait is a carryover from her previous life, as she was an introverted loner there as well.
• Not Evil, Just Misunderstood: People around Yumiella keep thinking the worst of her due to the fact she has black hair and dark magic, but she really just wants to be left alone.
• Not So Stoic: Despite her stoicism, the loneliness and scorn gained from her role gets to her more than she’s willing to admit and therefore Patrick's constant company means a lot to her.
• Oblivious to Love: She realizes relatively early that she likes Patrick as more than a friend, although she does initially think she's just mistaking her feelings, but it takes Patrick outright confessing that he was doing the same insane Level Grinding she proposed before (because she claimed she'd only marry someone stronger than her as a way to deter unwanted suitors) and already has reached level 60 that she realizes that Patrick feels the same about her.
• Person of Mass Destruction: Yumiella's ultimate spell, one that is only known to her and the Demon Lord, creates what is essentially a localized black hole. As a level 99 character, Yumiella's version is apparently capable of swallowing an entire stadium.
• Play the Game, Skip the Story: In-Universe. In her original world, she didn't much care for the romance options or story. What she really liked was the battles and gameplay, so she focused on dungeon diving and leveling up after recalling her past-life memories, which lead into the Wrong Genre Savvy aspect noted below.
• Power of the Void: Her strongest dark magic spells give her the power to instantly disintegrate any and all matter, and even create black holes.
• Scare the Dog: Any animal Yumiella approaches usually flees in utter terror. After hearing how Alicia sees her as a formless mass of black fog, she suspects animals see her the same way.
• Single Woman Seeks Good Man: She falls in love with Patrick because he's a good and caring friend to her, and he has always treated her like a normal girl while most people shun or distrust her.
• Smarter Than They Look: While she is a Cloudcuckoolander obsessed with getting stronger, Yumiella is actually very intelligent when it comes to academics, scoring high on her midterms.
• The Stoic: Consistently has a flat expression on her face. When she tries to force a smile, it looks rather unsettling. However, people who spend more time with her (like Patrick) can see the slight shifts in her face when she is upset or happy.
• Stronger Than They Look: Many people initially refuse to believe Yumiella being Level 99, due to that level being way above anything heard of before and her frail physical appearance. The Second Prince even tried to get her expelled by claiming she was lying. It isn't until she demonstrates how powerful she is that people start to accept that she's telling the truth.
• Sugar-and-Ice Personality: She is used to being alone and usually doesn't let her emotions show. Patrick is the only person she really opens up to because he's the only one who doesn't show any prejudice against her, eventually falling in love with him. She's also affectionate to her pet dragon Ryuu, thinking of him as her child.
• Super-Reflexes: Thanks to her high level, she has amazingly fast reflexes. She can dodge a direct attack from the strongest knight in the kingdom after quickly and calmly thinking how to react when the sword was coming at her.
• Super-Senses: It is noted several times in the series she has excellent eyesight and hearing due to her high level.
• Sweet Tooth: One of the few things that can grab her interest is sweets, such as when the Queen sends her some as a gift. An extra in the manga mentions that the maids on the Dolkness estate started carrying a pocket full of sweets with them simply to distract her when she was young.
  Yumiella: (Thinking) Our tongues were blessed.
• Thou Shalt Not Kill: Yumiella has no problem killing monsters, but she won't kill humans.
• Troubling Unchildlike Behavior: When she was five years old, before she had actually been taught how to read, her maids saw her writing notes to herself in an unknown language (actually Japanese from her previous life), which didn't help her sinister reputation.
• Unskilled, but Strong: Sparring with Patrick makes her realize that the only thing she has any actual skill with rather than just raw power is magic, and even then only her innate dark magic (whereas weaker but more skilled mages can use more than one element). Even though said raw power is so ridiculous that it hardly matters, she still decides she should start learning actual techniques because with her level already maxed out that's the only way she can get "stronger" than she already is.
• Well-Intentioned Extremist: She believes it's entirely possible for other people to become as strong as her and is always happy to give advice on how to do so. Unfortunately, the methods she used and continues to use are so dangerous that they're easily misinterpreted as her attempting to indirectly kill whoever she's helping.

• Wrong Genre Savvy: The beginning of the series shows while she correctly recognizes that she was reincarnated into a game with RPG elements, she strictly still treats herself as living in a game, rather than a universe with real people, and treats herself as a player character in an RPG, which contributed to her lack of social skills on top of her isolation due to her black hair.

Tropes applicable to her Light Magic and the Heroes counterpart

• Ambiguously Evil: The main character can only speculate why Yumiella become the secret boss as her motivations for that were not evident in the game itself. She also believes that Yumiella always had the ability to use dark magic, regardless of any trauma Yumiella gained throughout her life.
• Broken Bird: The main character believes that the original Yumiella must have felt lonely and rejected by everyone because of the stigma against her black hair.
• Driven to Villainy: The current Yumiella speculates that the game's Yumiella hit her breaking point partly because she was betrayed by Eleonora (or rather her posse) and also because of the persecution and rejection she suffered for her black hair by everyone, including her parents. Her becoming the devastating secret boss was her lashing out at Alicia as a scapegoat for her problems.
• Eerie Pale-Skinned Brunette: Her black hair and pale skin are part of her design as a villainess and user of dark magic.
• Failure Is the Only Option: In the original game, Alicia would eventually defeat Yumiella.
• Freudian Excuse: The main character speculates that Yumiella did not choose to be known as the demon child with black hair. Instead, she wanted to be loved and did everything to gain friends, but was all for naught. Her antagonism against Alicia is also believed to stem from envy because everyone loved her in the original game.
• Friendless Background: No one wanted to be her friend because of her black hair. It's so severe that even the main character finds this to be too much in Yumiella's shoes.
• Hated by All: One of the biggest parts of her character. Thanks to her black hair, no one loves her. She has no friends and her parents presumably want nothing to do with her.
• Hidden Depths: Implied. The main character is seeing the world through Yumiella's eyes, something that's also implied to have never been seen by the former when she was merely a gamer. This causes the main character to believe that there may have been greater circumstances that caused Yumiella to become the secret boss.
• I Just Want to Be Loved: Another part of Yumiella the main character speculates. Along with I Just Want to Have Friends, Yumiella wanted badly to have anyone to care about her and current Yumielle suspects one motivation for her becoming the secret boss was out of envy for Alicia having everything she wanted.
• Small Role, Big Impact: Her role has since been taken over by the main character, but it’s thanks to said role that would eventually lead the main character to see the bigger picture.
• Superboss: Her secret second role in LMH and the other reason she's so obscenely powerful. Alicia and all three of her love interests have to be nearly level capped themselves and properly geared to avoid simply being wiped out by Yumiella in the game.
• Tragic Villain: Possibly. If what the main character says is any indication, the amount of abuse and scorn would eventually lead Yumiella to become this.
• "Well Done, Daughter!" Girl: The main character believes that Yumiella eventually would resort to anything to gain her parent's affection.
• Willfully Weak: Yumiella was known to hold back her training, before becoming the most powerful boss in the game.
