Well, not having electricity won't bother Hitsugaya that much. Though he will be irritated at the fact that some idiot's blunder is what caused the outage. Look, incompetence is annoying, okay?

Cissa . . . will probably try to get the lights back on. She can see rather well in the dark, but the lights aren't supposed to go out like that. Therefore it needs to be investigated and fixed. By someone like her who knows what they're doing.
