Iris

• While both halves of Iris are kind, gentle and polite, they contrast in some notable ways. Blanche is overall more expressive, while Noire comes off as stoic and composed. Noire is the calm, proactive one, while Blanche is the caring, protective one. When it comes to conflict, they take different stances: Blanche prefers being non-confrontational to avoid unnecessary harm, where Noire is more prone to aggression when an issue persists. They are both valid problem-solving methods: one seeking to keep casualties to a minimum and the other seeking to neutralize threats or troublemakers before they start causing serious damage.
• In all, the contrast between Iris Blanche and Iris Noire's personalities can be summarize as sharing a set of core traits but differing in others. Soft and Warm (Blanche) Vs. Soft and Cool (Noire), Sharp (Noire) and Smooth (Blanche), Right-brained (Blanche) and Left-brained (Noire). They are two ends of a spectrum split down the middle. (This dichotomy also applies when it comes to intimacy: With Blanche being more submissive and easier to fluster, and Noire being more dominant and harder to fluster)
• Likes: Both Noire and Blanche love flowers. They also really love Tomato Juice, though it is unknown if it's because they like the taste or because they instinctively like anything reminiscent of blood (They are still vampires). Blanche enjoys painting and other artistic crafts, while Noire enjoys reading and learning new things.
• Dislikes: Both Iris Blanche and Iris Noire don't especially like anything made with garlic, as a Vampire's body doesn't respond well to it (they are prone to passing out if exposed to garlic products for too long). Neither of them can stand for injustice or disregard for life and nature. Blanche cannot stand people who are cruel or disrespectful to others, and Noire despises ignorance and arrogance.
• History: For many years, the two halves of Iris had lived on Whale Island: A floating, whale-shaped landmass above the rural village of Trampoli. The reason for this was because of the duty they performed and what it did for the people of Trampoli. Unlike humans, Vampires are naturally highly attuned to Runes: the incorporeal, magical essence that makes up and sustains the world. This also includes being able to influence the flow of Runeys, sprites that carry Runes.
• So, since Whale Island was kept afloat because of the Runes holding it up, it fell on Iris to keep it that way and prevent the island from falling on Trampoli. Thus Iris (and Later Blanche and Noire when Iris split herself) sang the Spirit Song to draw Runes to Whale Island, perpetually keeping it in the sky for uncounted years. However, due to recent developments, Iris Blanche and Iris Noire have been able to set their responsibility on tab, allowing them a fair bit more freedom. As a result, they moved down from their tower on Whale Island and started living in Trampoli itself, living at the village Inn in exchange for working its tavern.
• When speaking to each other, Noire and Blanche refer to each other as Iris, since they do not make a distinguishment between each other and actively want to be together, since they are technically the same person, just split apart. However, they do not mind if people refer to them as Blanche or Noire, since it's less confusing that way and makes telling who is being addressed easier. Also, contrary to what is believed, their status as vampires does not strictly mean they need to sustain themselves solely on blood, just as Succubi don't strictly rely on Runes to keep themselves healthy. They can still consume normal food & drink and stay sustained that way, but drinking blood every now and then does help.

Appearance:

• Iris Noire and Iris Blanche are identical, only with different looks. They share red and blue heterochromatic eyes, which eye is which color is the opposite of each other: Noire has red in her right eye and blue in her left, while Blanche and red in her left eye and blue in her right. Their complexion is that of a normal human, looking vibrant and alive instead of pale. They also have different hair colors and hair lengths: Blanche's hair is blonde and a little shorter, while Noire's hair is more of a pale silver that goes down to her shoulders. Both Irises are of slightly below average height (5 Ft or so) and their cup size is around an A to B.
• Clothing wise, Iris Noire and Iris Blanche wear the same clothes just with complementary/contrasting differences. Their daily wear is formal, almost noble-like: cuffed sleeves, a mantle cloak that drapes down their backs, and a blouse right on their collarbone. Their mantles are attached by chains, Noire's chain being silver and Blanche's chain being gold. They also have gems pinning their blouses, With a blue gem on Blanche's and a red gem on Noire's. Aside from a few traces of pink in their clothes (particularly in their pink underskirt), the fabric of Iris Noire and Iris Blanche's clothes is entirely monochrome: Noire's being all black, and Blanche's being all white. They both also wear a wood-carved ring on their left hands (gold-tinted on Blanche and silver-tinted on Noire), which then mirror each other whenever the two lock their hands together.
