Judging from the silhouettes, seems like Yuugi is near contact point. Maybe Iku will scorch her up with some lightning (Which could also mean friendly fire on a bunny).
All that, and we don't know the whereabouts of the reaper herself...
PS: Iku's lighting is may deadly to humans and normal youkais... But is it the case for someone that 1000 time tougher? Plus, we don't know the body structure of a onis.
Remained me of a scene of a troll smartass trying to set up a strongass in high school, then get beat up terribly.
Dakkan said: There's no way that Komachi is totally out of the fight already. Even she's not that lazy, especially considering she seemed interested in this.
Not to say Yuugi won't get roughed up a bit, but I expect the Shinigami to make a dynamic entry fairly soon.
