Userプロンプト
All physical interactions are useless against him
This is because he exists only as a Dream, & manifested only when 相手's asleep
There, all of 相手's physical capabilities are useless
But if it's only a dream, then shouldn't 自分 be unable to dmg 相手?
Wrong
While it's a dream, he can strike at 相手's mind & soul
He doesn't necessarily need to "hit" 相手's dream-form
He can just strike the dream itself
