The Sirens are a mysterious race of beings that have manipulated things to set up this reenactment of world war II. They generally take a hands off approach preferring to let the factions fight each other. However in they do show up themselves during game events.
Tropes that apply to the Sirens in general
- Alien Invasion: There are signs pointing toward the existence of alien life in the Azur Lane universe, and thus it has been theorized that the Sirens are aliens who invaded humanity in the future, before proceeding to travel to the past in order to further evolve.
- Alternate Timeline: The Sirens abuse this trope to perform their simulations. They leave humanity mostly to their devices in the timeline of the main game's storyline, but they do things differently in the timelines of the events in order to map out and see the various possibilities and consequences of their actions.
- The Visitors Dyed in Red and the Fallen Wings events reveal this trope to be played with. The Sirens technically do not travel through time: everything happening in main storyline and the events are occuring within an artificial world intended to recreate the past. It is because of this environment the Sirens can create singularities such as Mirror Seas and the Sanctuary in which the flow of time becomes unstable and thus can be manipulated. Many of the events involving Mirror Seas (with few exceptions) are simply the Sirens conducting different experiments for different possibilities, and they have been doing these for an incredibly long amount of time.
- Ambiguously Evil: The Fallen Wings event drops several hints that the motivation and purpose of the Sirens might be much more complex than what it seems at first. It is clear that the Sirens seek evolution and growth above all else, but as for why, there are multiple possibilities shown:
- The conversation between the Inquisitor and the Siren Observer Zero implies the existence of a third party whom humanity cannot defeat, even with the power of the Sirens. This would push the Sirens to Well-Intentioned Extremist territory since they are manipulating humanity for the sake of evolution against a greater threat. However, this wouldn't match up with the behavior displayed by Observer Alpha and Tester Beta thus far, who are both darkly amused by how they manipulate humanity without worry of a physical threat.
- The same conversation also posits the possibility that not all Sirens are hellbent on manipulating and using humanity, as Observer Zero/Dearmweaver is explicitly ordered by the Inquisitor to save the past of humanity, possibly implying a conflict of purpose between among the Sirens.
- Animal Motifs: All the Sirens are designed around marine life, like various types of cephalopods all the way to stingrays and hammerhead sharks.
- Armor-Piercing Attack: Most Siren attacks are blue armor-piercing shells, which can do massive damage to your heavier ships. However, there are some normal shells in their mix, and Oceana's most devastating attack is her close-range purple HE barrage.
- Big Bad / Greater-Scope Villain: The Sirens are the source of the Mental Cubes which give birth to the Kansens/ship girls. The only reason humanity is even divided into factions in the first place is because the Sirens indirectly spread the Mental Cubes to various factions. While the Sakura Empire and the Ironblood are the main antagonists faced throughout the main story, it's often implied and later outright said that they believe the Sirens to be gods and that serving them will pave the best future for humanity. Meanwhile, the Sirens themselves are created by, and operate according to the wishes of the Creator: a mysterious entity who all Sirens serve. This would make the Creator a Greater Scope Villain to the Sirens, themselves Greater Scope Villains to the Sakura Empire and Ironblood factions.
- Blue and Orange Morality: Subtle, but becomes noticeable when one studies their motivations. They are willing to wage war, eradicate an entire species, decimate an entire world, all for the sake of evolution. When the world and humanity are too deteriorated to suffice as their opponents, they simply go to the past and subtly help them advance and evolve (by giving a bit of their own technology) for them to become their opponents. Their sheer dedication and effort for their own evolution and growth are nothing short of monstrous.
- Taken even further when it is shown that their obsession with evolution is intimately linked with their desire to please and become closer to their Creator, who is very whimsical in their choices and preferences. Even Observer Alpha has complained that the Creator has a "sick sense of humor."
- Chess Motifs: Their mook ships are named after chess pieces with Destroyers being called Pawns. And in the 'Opposite Colored Mirror' event, it's revealed they refer to both their own ship girls and the Azur Lane's in such terms.
- Dark Is Evil: The Siren mook ships and their ship girls tend to wear black and armed with black equipments.
- Eldritch Location: The Mirror Seas, distortions of the time flow which manifest only upon certain regions of space on the ocean. Within the Mirror Seas, events akin to Alternate Timelines come to existence, anchored into reality through observation of powerful entities.
- On that note, "the Sanctuary" first introduced in Visitors Dyed in Red, a place where the Sirens harvest the souls of Kansens to create copies of them. Their control over reality within the Sanctuary is immense, allowing the Sirens to go as far as to simply pause and reset reality as they please.
- The Fallen Wings indicate the entire planet may have become one of these, as the Sirens can conjure the Mirror Seas and the Sanctuary only because the world is now an "artificial environment" at least according to the Inquisitor and Observer Zero.
- The End of the World as We Know It: The Sirens have already eradicated humanity in the future. Assuming it was not caused by another race entirely.
- Human All Along: The Fallen Wings event indicates the Creator whom all the Sirens serve might be actually human, or originally human. The ending quote of Fallen Wings suggests the identity of the Creator to be Key Point: G's Commander.Mankind, actually lives a humble existence... but our small bodies are filled with infinite expectations and ideals. We often put our own expectations and ideals and shape them to our desires, hoping they are eternal and powerful. Once strong enough, they will replace our ephemeral physical existence and become an infinite spiritual sustenance this is also the meaning to your (Enterprise's) name. But one day, if mankind abandons our highest ideals, and embarks on a completely contrary path are you willing to help us correct the wrongdoings of the future?
- Icy Blue Eyes: The second stage series Sirens have blue eyes rather than gold.
- I Need You Stronger: The Sirens want the ship girls belonging to humanity to become stronger so the Sirens themselves could evolve and grow from conflicting with humanity.
- It Amused Me: All the Sirens shown so far display various levels of glee and amusement in their machinations and their manipulation of humanity, with few exceptions.
- Lotus-Eater Machine: According to the Fallen Wings, the entire world of Azur Lane is set within an artificial world. Unlike most fantasy and sci-fi examples, the environment is very real (not a Mental World nor a Cyberspace) though both the Sirens and the Creator (implied to be the entity behind the world's creation) refer to humanity and the Sirens themselves as programs. The artificial world's purpose is to continuously force adaptation and natural selection upon the ship girls and humanity, thus engineering evolution through unending selection and strife. As the Sirens are capable of rewriting the world to an extent via projecting singularities, they are effectively travelling through time from the perspective of humanity, who are unable to do the same and could be affected by the singularities.
- Meaningful Name: Sirens are known to sing songs which tempt shipmen and lead various ships into crashing onto rocks and sink. Exactly like how the Sirens tempted the Sakura Empire and Ironblood to defect from Azur Lane and halt the voyage of humanity into crashing to a rock of mutual conflict.
- Mystical White Hair: The humanoid Sirens tend to have white hair with a slight hue of dark purple.
- Not So Omniscient After All: Visitors Dyed In Red has the Observer come to the realisation that, despite what they may have thought, they are not in control of everything. This is brought on by Shoukaku managing to break free of brainwashing to protect her sister. There's also the fact that they have no real control over G, to the point that, in Winter's Crown, Purifier only gets her to not blow up most of the Northern Union by luring the Royal Navy forces towards her.
- Only Known by Their Nickname: Or in this case, codenames. All of the important Siren figures so far are named after their classes (Observer Alpha, Tester Beta, Purifier). Only Observer Zero and Key Point: G seem to have actual names, Lyn and Enterprise, respectively.
- Orcus on His Throne: Somewhat downplayed. In the timeline of the main game, they're content to observe the ongoing events, but in the timelines of various events including the 'Frozen Crown' and 'Ink Stained Sakura', they're willing to get their hands dirty.
- Supernatural Gold Eyes: Most of the humanoid Sirens generally have these.
- Time Travel: The Sirens are heavily hinted to come from the future, and their mook ships (seen in events only) look the part. Though with the revelation of their use of a world-scale and a very real form of a Lotus-Eater Machine, their actions only has the semblance of time travel.
- Tron Lines: Mook ships have glowing orange-red patterns or lines that strobe on and off.
- Bare Your Midriff: Her outfit bares her chest with just an open coat over it.
- Stripperiffic: She wears a very skimpy black bikini with an open coat.
- Arm Cannon: She has a weapon arm, on which arm depends on which way she is facing.
- Bare Your Midriff: She only wear a skimpy top with short shorts.
- Girlish Pigtails: She has thick waist lenght twintails.
- Slasher Smile: Her default expression
- Who Wears Short Shorts?: Her shorts barely cover more than Explorer's bikini.
- Bare Your Midriff: Likewise, her outfit is midriff bearing.
- Boss in Mook's Clothing: Her heavy armor and huge HE shell barrages make her much more dangerous to the vanguard fleet than the other generic Sirens, yet she isn't treated any differently than the other roaming Sirens and she's one of the most recurring ones after Explorer and Tracker.
- Expy: of some Kantai Collection Abyssal bosses.
- Orcus on His Throne: She sits on a rigging which houses her weapons.
- The Computer Is a Cheating Bastard: She has heavy armor despite being a heavy cruiser.
- Eyepatch of Power: Hers looking like a cyborg implant.
- Leotard of Power: White leotard with some black belt-like rigging.
- Multi-Armed and Dangerous: She has Doc Ock style mechanical arms on her back with weapons on them.
- Names to Run Away from Really Fast: Her name is by far the most intimidating of the generic Sirens and as a battleship, she packs a serious punch.
- Badass Longcoat: Wears a longcoat with the inside glowing yellow or blue.
- Bare Your Midriff: Her open coat doesn't cover her chest and unlike Explorer, she does not wear anything else other than her shorts underneath.
- Evil Diva: Or more appropriately evil DJ.
- Headphones Equal Isolation: Probably to give her a DJ appearance.
- Who Wears Short Shorts?: Like Tracker, she wears very short shorts.
As an observer, she interacts with the protagonists sparingly. Alpha spends most of her time working behind the scenes to collect data, sending them to both the Creator and Tester Beta so the parameters of the next simulations could be better adjusted.
- Combat Tentacles: Has a set of these coming from her mechanized seat.
- Deadpan Snarker: Not so much deadpan but definitely snarky; being playful, sarcastic, and prone to sniping comments which are difficult to distinguish from insults. This is especially notable in her first conversation with Key Point: G in Fallen Wings.
- Does Not Like Shoes: One of the only characters in the entire game without any sort of footwear.
- Hair Decoration: She wears a black metal headband with two bunny-like ears.
- More Dakka: Her mechanized seat has four cannons on each side of its 'wheels'.
- Ms. Exposition: Along with Tester Beta, she often ends up explaining the reasons and the results after each experiment the Sirens had just finished, particularly in the events.
- Rapunzel Hair: Her hair is probably as long as, if not longer, than she is tall.
- Red Oni, Blue Oni: Being the blue to Tester Beta's red, being the more observant of the two. However, there are times when this is flipped around: during the Visitors Dyed in Red Alpha is more exasperated and annoyed by the Creator's sudden decision while Beta remains calm and accepting.
- Stripperiffic: Her clothing is basically a small swim dress probably intended for children, with an opening which leaves her stomach and a bit of her lower body bare.
- Super Wheelchair: Though Observer Alpha is obviously not crippled, her equipment pretty much looks like two wheels with cannons and tentacles with a seat in-between them. She also seems to travel across the sea while remaining seated without her feet touching the water at all.
- Those Two Girls: With Tester Beta, being the two most commonly seen important Siren figures, and the ones in charge of observing and testing humanity.
Despite being a tester, she still interacts very little with the protagonists; so far her gameplay appearance as an enemy boss is limited to being the Bonus Boss of Fallen Wings event. Her main role is to determine if the parameters given by Observer Alpha is satisfactory.
- Animal Motifs: Her backpack equipment resembles a manta ray.
- Bare Your Midriff: Her outfit is basically a black Chainmail Bikini combined with very short shorts which emphasizes her figure.
- Bonus Boss: She is the boss of Stage Extra of the Fallen Wings event.
- Deadpan Snarker: Much like Observer Alpha, Tester Beta is rather snarky and is unlikely to spend a scene without a witty remark to someone or something.
- More Dakka: She has a grand total of 12 visible cannons, there are three on top of each wing of her backpack and there are a pair of triple-barrel cannons extending under the wings.
- Ms. Exposition: Shares this role with Observer Alpha.
- Psychotic Smirk: Her default expression, which says a lot for her personality.
- Punny Name: Her name is Beta, making her a Beta Tester. Fittingly, part of her job is testing humanity and the shipgirls' progress.
- Red Oni, Blue Oni: Being the red to Observer Alpha's blue, being the more active and tenacious of the two. However, there are times when this is flipped around: during the Visitors Dyed in Red Alpha is more exasperated and annoyed by the Creator's sudden decision while Beta remains calm and accepting.
- Those Two Girls: With Observer Alpha, the two are the most commonly seen important Siren figures in the events.
- Who Wears Short Shorts?: A black one, as with every other objects Siren-related.
- Zettai Ryouiki: Wears black leggings up to her thighs, along with some sort of black mechanized cuisses with golden markings.
In the event, Observer Alpha orders Purifier to try and prevent Key Point: G from creating a singularity around North Europian Union territory. She is overjoyed about the prospect of battling 'the legend' in person, but she is fully aware she is unlikely to finish the mission on her own.
Thus, Purifier instead allows the Royal Navy ships to follow her while she goes to find the Key's location. When she finds G near the end of the event, the Purifier asks the Key's motives for building a singularity capable of nuking half of North Union to oblivion, and warns her to stop.
The Key doesn't listen, but when Victorious of the Royal Navy arrives, G halts and asks Purifier if she brought the ship girl there, which Purifier affirms. Grudgingly, the Key dispels the singularity and warns Purifier about "involving outsiders", promising her wrath if the Sirens try it again, before leaving.
Her mission accomplished, Purifier then decides to reward the Royal Navy ships by engaging them in battle, becoming the Final Boss of the event. However, despite being sunk in the ensuing clash, Purifier returns unharmed in the epilogue, conversing with Observer Alpha about the potential of Mental Cubes and the experience she gains from her defeat. Purifier gleefully asks Alpha for more, to which the Observer replies by asking if Purifer doesn't mind 'cherry blossoms' for her next mission.
- Attack Drones: Seems to have two smaller units accompanying her, each with a pair of cannons.
- Animal Mecha: Her huge equipment resembles a hammerhead shark larger than her entire body, with a pair of cannons on each of its fins. Though it doesn't seem to be alive or independent, Purifier does ride on it in her chibi battle sprite.
- Animal Motifs: Sharks. Her equipment is designed like a shark, and her attitude in battle can only be described as a cheerfully sadistic predator.
- Back from the Dead: Death doesn't even inconvenience Purifier all that much, as at the end of Winter's Crown she returns as soon as she was sunk. Judging from Observer Alpha's comments, it seems to be a case of Body Backup Drive, as she considers Purifier's sinking to be a 'loss of resources'.
- Bare Your Midriff: Her sailor shirt cuts off well above her navel.
- Blood Knight: There doesn't seem to be anything which Purifier enjoys more than fighting. She is excited at the prospect of battling Key Point: G despite knowing she is outmatched, and doesn't even bat an eye when she returns Back from the Dead after being sunk by the protagonists, only happy she has gained more experience through combat and thus could fight better.
- Casual Danger Dialogue: Even in the face of overwhelming odds, Purifier keeps her cheerful attitude in stride.
- Deadpan Snarker: Seems to be a recurring theme for the Sirens by this point. She is not deadpan at all, but she makes an effort to make fun of everything she could: for example, she nicknames Key Point: G as "Ms. Little Sunshine" (in the English version).
- Final Boss: Of Winter's Crown event.
- Genki Girl: A darker example than most. She is a bubbly girl with a happy-go-lucky attitude matched only by her pure joy of the thrills of battle.
- Names to Run Away from Really Fast: Among the Sirens with story roles, her name alone implies violence, and she does quite enjoy her job of "purifying" Siren experiments.
- Rapunzel Hair: And how! Her hair is about twice as long as she is.
- Slasher Smile: Her default expression, at any rate.
- Surfer Dude: A female example. The way she speaks is Somewhat Radical, and she travels across the sea by riding on her shark-shaped weapon equipment.
- Vapor Wear: Her sailor shirt is rather transparent, and appears to be wearing nothing underneath.
- Who Wears Short Shorts?: She appears to be wearing bike shorts.
- Zettai Ryouiki: Wears white form-fitting leggings covered with black and yellow mechanized greaves, which reaches up to her thighs.
Code: G (Chinese); Key Point: G (Japanese); Enterprise (English)
A Siren who appears suspiciously similar to the Eagle Union's representative ship Enterprise, who makes her debut during the "Fallen Wings" event.
Referred by the other Sirens as "Key Point: G" - her introduction begins with a log showing a Cryptic Conversation between herself and Observer Alpha, who congratulates G for 'saving the world again'. Alpha also reveals G to be the model for all the current Sirens, including Alpha herself, as well as the 'Key' to their Creator. G is then offered a choice to participate in another round of 'game' by Alpha, to which she reiterates that her choice will always be the same, until she finds 'that person'.
After a series of flashbacks full of Cryptic Conversation with her own commander in her past as Enterprise, near the end of the event G confronts Washington, North Carolina and Helena by wiping out the Siren fleet attacking them, and asks a question about their commander's name. After North Carolina refuses to answer and recognizes her as Enterprise, G denies the notion and decides to leave for parts unknown, moving out of the observations from the other Sirens. Tester Beta wonders about what she is up to and why she specifically targets this 'time period' but Observer Alpha is assured that Key Point: G will join them again.
- The Ace: Much like Enterprise, she seems to be this for the Sirens. Observer Alpha and Tester Beta only call her for special simulations, and both of them as well as many other Sirens are modelled by the Creator after her. During the simulations, G is free to intervene as she pleases and demonstrates her power by singlehandedly wiping out an entire fleet of Siren ships with no effort.
- The Frozen Crown event goes even further: it is shown G can in fact create a singularity on the scale of Mirror Seas with sheer force of will. To emphasize how dangerous that is, Purifier claims Sirens on her class could never create one on their own, and if improperly dispelled, the singularity could be weaponized as a Fantastic Nuke powerful enough to damage continents. Suddenly the theory claiming her to be the Nuclear Enterprise makes a whole lot sense.
- Alternate Self: Her flashbacks suggest she is actually an instance of Enterprise from the future the Sirens came from. Fan speculation holds that she might be the personification of CVN-65 Nuclear Enterprise.
- Archer Archetype: Like Enterprise, G carries a large metallic bow which she seems to use as aircraft launchers. She also fits the archetype straighter, being much colder, detached, and generally Darker and Edgier.
- Barbarian Longhair: Combined with Mystical White Hair of Enterprise's. G's hairstyle makes it seem she has been fighting for quite a long time without a chance to take care of her hair.
- Broken Ace: Heavily implied to be one. For all her abilities and her status as The Ace, she seems to carry a lot of emotional baggages, even more so than the protagonist's Enterprise and any other ship shown so far.
- Clothing Damage: Both her coat and her right legging are torn up in a few places, conveying her combat experience.
- Conspicuous Gloves: She wears a pair of black gloves long enough to reach just before her shoulders.
- Cryptic Conversation: She engages in this trope a lot, implying she knows a lot more than most about what is really going on within the Azur Lane world.
- Darker and Edgier: Though easily identified as Enterprise, her overall appearance gives off a very grim outlook as if weary of conflict. Even her manner of speech is considerably more detached and colder than Enterprise. Even her eagle looks more sinister than Enterprise or Yorktown's.
- Despair Speech: The opening lines of Fallen Wings are implied to be her lamentation about her fate."I thought by defeating all my enemies Id finally get some peace. But it appears the future has betrayed us. No matter the effort, there will always be battles ahead. One by one they stand defiant in front of me and one by one their faces disappear behind me I cant remember them anymore. It is time, sisters. The stars are mesmerizing tonight."
- Dull Eyes of Unhappiness: Which sets her apart from almost any other character in Azur Lane: her dark grey eyes make her seem like she is in a perpetual state of giving a Death Glare.
- Evil Doppelgänger: A possibility for the nature of her existence, but whether or not she is one (or whether she is even evil in the first place) isn't yet clear.
- Eye Color Change: G's eye color is surprisingly inconsistent. On closer look during the Fallen Wings trailers and teasers, she has the same purple eyes as Enterprise. However, her in-game portrait makes her eyes look like a dull dark grey. Further, in the CG picture dedicated to her as well as in the trailers/teasers, her eyes briefly turn red.
- Fantastic Nuke: G is apparently able to construct a singularity on her own. According to Purifier, improper collapse of her singularity can obliterate half of the North Union's territory.
- Fashionable Asymmetry: Her right leg sports a thigh-high legging while her left lacks any. Subverted in the sense, judging from the damage on her legging, it seems to imply she lost her left legging (possibly in combat) and simply doesn't bother to replace it rather than out of fashion sense.
- Iconic Outfit: Her mantle coat, which G wears like a cape. It is how North Carolina identifies her as Enterprise.
- I Will Find You: Her stated goal. The identity of the person she seeks isn't mentioned outright, but she did question about the name of Azur Lane's Commander (i.e. You, the player).
- Lonely at the Top: How Observer Alpha describes her. "The strongest people possess the loneliest souls."
- One-Man Army: She singlehandedly destroyed at least one Siren base and an entire fleet of Siren ships. Something which the Azur Lane's ship girls could only manage in fleets.
- O.O.C. Is Serious Business: Her actions and behavior in Winter's Crown event paint a somewhat different picture of her personality than what is implied in Fallen Wings. Whereas G completely ignores Washington and Helena and barely speaks with North Carolina, she is far more polite in conversing with Victorious. G even goes as far as to verbally express joy to see her again and praise her, noting Victorious will grow stronger in the future* . In addition, despite being The Stoic, G promises her wrath when she warns Purifier not to involve 'outsiders' again.
- Person of Mass Destruction: Even more so than Enterprise. See Fantastic Nuke above.
- Red Eyes, Take Warning: In the trailers and teasers of the Fallen Wings event, G's eyes briefly glow red whenever she is shown.
- Scarf Of Asskicking: A black one to match her Darker and Edgier theme compared to Enterprise.
- Shell-Shocked Veteran: If her Despair Speech is any indication.
- The Stoic: In her appearances so far, she reacts to everything with dull responses. Not even being mocked by Observer Alpha elicits anything more than a calm, restrained retort.
- That Man Is Dead: Her only response when North Carolina recognizes her as Enterprise is to stoically claim "you've got the wrong person" or "you're mistaken" depending on the version.
- Ultimate Lifeform: Averted. Observer Alpha describes her as "the most perfect, the most flawless" model, and the current Sirens are molded after her image. Emphasis on the most - just like all the Sirens, the fact she is the most perfect does not mean she cannot evolve further; which is implied to be the reason for her current position among the Sirens in the first place.
- Walking Spoiler: The Fallen Wings is about G's nature and past, which is intimately connected to the future from which the Sirens came from. Her backstory isn't even fully explained and it already gives away several hints (sometimes conflicting) for the nature of the Sirens.
- Wide-Eyed Idealist: Implied to be one in her past, much like the protagonist's Enterprise. Her flashbacks show how Enterprise asked her commander about the civilizations of other stars, and she further expressed her excitement to meet them.
- Wild Card: Her current role. G participates in the simulations of the Sirens, but the Sirens have little-to-no actual control over her actions and G moves entirely by her own motives. She also has no desire to be cordial with the protagonists and expresses her hostility without hesitance, at least in Fallen Wings.
- Worthy Opponent: Seems to see Victorious from the Royal Navy as this. When G wipes out an entire fleet of Sirens in Fallen Wings, she uses unidentified Siren plane models. However, G goes out of her way to use the exact same plane models Victorious uses (Fairey Barracuda) to shoot down the latter's planes during their skirmish near the end of Winter's Crown. G is also much more cordial with the British ship girl than with anyone else so far (barring her Commander).
Observer 0 (Chinese, Japanese); Dearmweaver (English)
During the third scene of the event, Observer Zero is shown having a Cryptic Conversation about the fate of humanity with an equally enigmatic character named the Inquisitor when the latter's fleet is being overwhelmed by an unknown enemy.
The Inquisitor laments the fact that humanity couldn't win even with the power of the Sirens, and together with Observer Zero they discuss the true nature of the 'simulations' done by the Sirens as well as its purpose.
The Inquisitor then tells his "beloved Zero" to begin the Inquisition Plan, telling Zero the past of humanity is now in her hands. Accepting the mission, Zero leaves as the Inquisitor goes on a suicidal last stand.
- Amazing Technicolor Population: Not merely an albino, everything about her except for her visible eye, a few strands of her hair, a few parts of her clothing, and her equipments are colored pure white.
- Animal Motifs: Jellyfish. She has a giant jellyfish-like compartment dyed in transparent blue behind her body, and her white mantle would make her look like a white jellyfish if she covers her body from view with it.
- Cryptic Conversation: Pretty much everything she has ever said so far. The English version of the Fallen Wings even adds a new scene which entirely consists of her having a very vague monologue to herself (or her allies, not even that is clear).
- Does Not Like Shoes: One of the only characters in the entire game to leave their feet bare in their potraits.
- I Have Many Names: Apart from being Observer Zero, she has been called Lyn, and the English version of Fallen Wings also names her Dearmweaver (which might or might not be intended to be Dreamweaver)
- Innocent Blue Eyes: Her only visible eye is glowing light blue, which stands in stark contrast to the Supernatural Gold Eyes that all Sirens (bar Key Point: G) exhibit.
- Intrigued by Humanity: In her new scene in the Fallen Wings, she comments that humanity really makes things interesting for her.
- The Last of These Is Not Like the Others: Unlike every other Siren shown so far, her name is colored green (as opposed to the usual red) which signifies her as an ally. This is in spite of the fact that she never even interacts with the protagonists yet.
- Lonely Doll Girl: Her general theme, reinforced by the fact she is never seen interacting with the other Sirens and the small doll she carries everywhere she goes.
- Multicolored Hair: A small part of her bangs are colored with blue matching her visible eye.
- Peek-a-Bangs: Her bangs cover her right eye from view.
- Sci-Fi Bob Haircut: Combined with Mystical White Hair which enhances her enigmatic impression.
- Shout-Out: Her general design brings to mind the princess-class and the generals of Abyssals from Kantai Collection.
- Simple, yet Opulent: Her small dress and huge mantle are a rather simple clothing design for Azur Lane characters, but it makes her stand out from the others all the same, especially when compared to the other Sirens.
- Walking Spoiler: Even more so than Key Point: G, seeing as her first lines alone spoil the nature of the entire Azur Lane world as well as the Sirens' methodology.
