Since I am doing a story revamp, and noticed I haven't made a separate bio for Karuna, decided to just put the sisters together now. Also came up with a new origin for Moth Spirits for this new story that's simpler.
Their info below:
Moth Spirits: They are said to be born from the souls of unborn/children who died very young before their lives even started, often manifesting in areas where such death has occurred sometime ago. Typically, they never appear as babies, but around 3-4 year old children. People who adopt them tend to still count their first appearance as their "year one"
Names: Mari & Karuna (Karuna's means "hunt and drive away evil spirits" roughly translated)
Heights: 160 cm (Mari) 182 cm (Karuna)
(Karuna was initially just known as Karuna, but after Mari joined them, she wanted to be called with the same surname. Neither could take on their mother figure's surname, as technically the head Priestess is not allowed to have children of her own, so they got around that by giving the two different surnames from Erena's.)
Ages: 23 (Karuna) 16 (Mari)
Family: Adoptive mother figure Erena Mizuka
Friends: Yago (A chimera), Shizuka (A water spirit) Milo & Silas Chiba (names pending for change), Karuna also often hangs out with Akiko, who's closer to her age than the rest.
Love interests: Mari has a crush on Milo and vise versa, but they're also somehow too dumb to realize they have said crushes.
Abilities:
Mari:
Basic moth spirit abilities; flying, poofing into butterflies, pocket dimension to store stuff, glow-in-the-dark wings, sleep inducing vibration from her antenna, spitting webs. Screeching loud enough to shatter glass and break eardrums.
Spells: Some basic water-based magic healing spells her adoptive mum taught her.
Singing: Mari can sing well, and can use it to calm scared kids or lull babies to sleep
Kicks: Mari has very strong legs and can kick you across the room if she wants to.
Karuna:
Levitation: She can't fly but she can hover using her wind magic. She can also levitate other people and objects with it.
Wind magic: She can use strong gusts of wind to slice through and break things or create strong shielding bubbles that most physical attacks can't go through. She can also create air bubbles underwater. She typically creates strong gusts of winds by either slashing with her claws or kicking with her legs, or just blowing air out of her lungs.
Physical strength: She is insanely strong due to being a dragon, able to tear up trees from their roots, breaking thick walls with her fists (accidentally sometimes) and kick things to the stratosphere
Dragonic form: She can turn into a dragon, though she can't stay in this form for long due to her birth defects.
Weaknesses:
Mari
Mari struggles to form connections with new people, and for the longest time her only friend was her sister Karuna. Even nowadays she tends to act suspicious towards anyone new, creating lot of awkward situations. She is also quite naive, so once her trust is gained it can be easy to trick her into doing something stupid.
Karuna
Karuna is self-conscious about her lack of wings and doesn't really like it if people point it out too much and question if she is a proper dragon at all. She often underestimates her strength, causing her to break things without meaning to.
Personality:
Mari is a very curious person and easily excitable, often getting involved in harmless mischief or even causing it by herself. She’s very protective of her home temple and will be on the front-lines defending it (even if it might not be the greatest idea.)
Because of the stigma around her kin, she does have some self-esteem issues, and tends to take comments from visitors really hard, those who believe in the myths that her kin are bad luck and bad omens. When this happens she tends to hide away and it can take hours to find her.
Because of this, she ultimately doesn’t trust “outsiders” that much and tends to spy on any guests to determine what kind of people they are, rather than coming to say hello normally.
Karuna is very friendly and quite expressive despite being mute. While she mostly comes off as goofy, well-meaning but clumsy person, she's more intelligent than people think. When push comes to shove, her sharp mind and ability to anticipate attacks and sense danger shines through.
She can be quite aggressive and scary if she wants to be, something natural to all dragons. Mostly Karuna is pretty chill, going along with Mari and her friend's shenanigans while subtly making sure everyone is safe.
BG Story:
Karuna appeared first, her egg having been found abandoned by some of the priestesses, who decided to take her in. She has become kind of a Guardian for the place under Erena's guidance. Mari in turn was found by one of the shrine maidens wandering around in the nearby woods when Karuna was 7, where it was said a child had died sometime ago during winter storm couple years ago.
Erena took her under her wing as well, giving her the name "Mari Haruko" as she wasn't allowed to officially adopt her and give her her surname Mizuka. Sometime after this, Karuna asked if she could also be called "Haruko" too, having become a big sister figure to Mari.
Fun Facts:
Karuna often lets Mari ride her shoulders
Mari has never seen Erena's true Water Woman form, but Karuna has and understandably finds it scary.
Karuna has never shown any interest towards romance, nor attraction to anybody, though there have been visitors who've found her attractive, mostly Bi/Pan/Lesbian women.
Karuna and Akiko can be quite the scary pair to fight against, given both are quite the heavy hitters, and both use wind element.
They often go on adventures in the forest surrounding their temple, or follow along the river that eventually reaches the lake where the Kureshima bathhouse is.
They actually met the Murasakis the first time by accidentally crashing on their island, as Karuna lost concentration and fell on Mari, causing them both to plummet into one of the hot springs there.
The meeting was initially a bit hostile as Karuna sensed these people were soul eaters, but the lake's spirit Shizuka helped ease the tensions and make the sisters trust her that these people weren't dangerous to them.
Mari and Karuna were both initially a bit sus towards Ayame, the snow woman who lingers around the mountain the forest leads to, who becomes close with Erena.
As it is revealed that Ayame was the one who led the shrine maiden to Mari however, the two warm up to her.
