* AlwaysCamp
* BerserkButton: If you think dressing up as the [[spoiler: man who attempted to rape Eiri in order to "heal him psychologically"]] is a good idea, you've got another thing coming.

The stress of worrying about Yuki, and the lengths that Tohma would go to in order to do what he perceived to be in Yuki's best interests--including ''threatening Shuichi's life''--put Mika in the hospital. At least Tohma toned it down a bit when he realized he could lose his wife and child if he kept up his antics.]]
