Backtagging: Sure! Threadjacking/threadhopping: With prior warning would be nice! Fourthwalling: Sure!
ACTION
Fighting: Be prepared. Injuries: Go for it Killing: Sure, with a good plot Telepathy/mind-reading: That would be interesting, go for it!
RELATIONSHIPS
Hugging: Ifyou are Ichigo, she will never let you go. Anyone else she will be careful not to break any ribs. Flirting: lol what is that. Kissing and/or other intimate actions: She pretty much as Ichigo on the mind at all times, so if you think your muse can compete/deal with that in a relationship then we will see. It takes alot though.
Anything else you'd like to make known?: WHERE IS ICHIGO
