He and I were assigned to the same room - but I would rather know where my brother is at night, than accept such assignments. [selfish? yea. but higekiri doesn't care about much. he's old, after all, and he mostly cares about his brother

who is currently hurting]

I do not know if I care... but the demon managed to injure my brother on the way to its prey.

[even if it was just emotionally,

and so higekiri finds that rather unforgivable]

I wonder if this is what would be called a 'personal vendetta'?
