Imagination:
This is an ability which is passive in nature, basically the reason why Akabane won't die is he can't visualize himself dying or dead and has no clue what death is in relation to himself. Basically what this means is Akabane would not be touched/harmed by any thing he can't visualize hitting him or harming him. It would not affect your character personally, it just would affect what your character might do to Akabane. [
example]
How willing are you to be affected by this should he decide to use it?
Just what would be affected if it would work on your character?
Feel free to skip the above questions if your character has no fighting abilities or is completely normal/mundane in nature.
Carving:
Akabane is fond of leaving the letter J on people's backs/bodies/clothing during his fighting with them at times, can he do this should you get into such a fight with him?
Death:
Can Akabane kill you should you either get; in over your head with him/annoy(bore)him or just plain irk him until he just decides to snuff you out like a candle wick?
Thieving:
Do you have any abilities that Akabane could steal for his own use if his blood somehow was mingled with the result of these abilities?
[Refer to this for how he manages this:

Stalking:
Should Akabane take an interest in you can he stalk you/provoke you into a fight/bring you fruit baskets when you're not feeling well?
Anything else?
