Admin Mawile: (`・ω・´)ノ Hmmm, well, I don’t like ruling any kind of personality out, so these are just things that would be hard to deal with for them, or not particularly preferable.
Ruki: Someone undignified, disobedient, or unwilling to change. Too much willpower, and a bad attitude, especially with him.
Kou: Too selfless (not fitting in with his view of the world), someone who’s ungrateful, too boring or easy to read, or tries to lie to him too often.
Yuuma: Not appreciating his garden, not getting along with his family, someone wimpy or mentally weak, someone fragile and hard to deal with.
Azusa: Someone who won’t hurt him, unnecessary cruelty, someone who will leave him by himself for too long, not getting along with his brothers.
