I know, I know, you guys are probably thinking "hey! you forgot to color this picture" well you're WRONG

This is a detail I've never given to much importance and I've probably mentioned it just a couple of times, but Kira's clothes are actually white, they look black because Kira has the passive ability of using shadows to cover her clothes allowing her to control them to some extent as in shapeshifting some parts of it like turning the sleeves into claws, this also serves as a sort of armor

There are few moments when her clothes are seen white and this usually occurs when she loses her powers, there're several ways of how she can lose these but more common ways are: continuous exposition to direct sun light or other intense light sources, with magic or sealing her powers in special objects, taken away or absorbed by other demons (Kira's father and Dante can make her lose her powers temporary), etc

Usually when Kira is in this state she can be considered completely human as she can't use any of her demon powers and it's highly vulnerable, however in this state she can actually tolerate the sun and other light sources a little better but at the same time the more she stay exposed to these the more it'll take her to get her powers back (and she'll feel weak and exhausted)

Also taking the chance to also mention that Kira has the ability of healing others by absorbing their injuries (an ability that she got from her mother), this of course will damage Kira with the same injuries but she can regenerate to some extent so most of the time it shouldn't be an issue, however the more serious the injury the more it'll take for her to recover from it and it'll consume more energy, this is also why fatal injuries are dangerous for her to deal with, logically this ability can't (or shouldn't) be used when she's in human state as she doesn't have regenerative capacities in this state. This also works the other way around, Kira can transfer her injuries to others (as a way of healing herself) but due to the dark nature of it she avoids to do that as she considers it wrong

An extended version of that ability allows her to heal someone transfering their injuries to other being by using her own body as an intermediary, this is a bit more complicated and requires more energy and a third party, and just as the past scenery she considers it to be wrong

pheww, sorry for the long text, I thought maybe some of you would find it interesting :>

I'll probably make a Kira's ref soon where I'll include all of her abilities

also white birb because reasons ¯\_(ツ)_/¯
