.>w<; Nice-o-verse Ulquiorra is a tough case. I wouldn't say he gets "nicer", exactly... welp, in fact he gets a lot more cranky by nature. Much more expressive. This does the opposite of making him easier to get on with. XD Instead of being quietly tolerant and/or subtley throwin' shade, he'll let you know he'd like you to jump into the sea.

It would be dissonant to someone familiar to canon Ulquiorra. XD As dissonant as seeing this alternate Quarta getting along with Nice-jow. XD Which happens.

He does not get along well with cheeky fruit bats trying to steal nectarine slices right out of his face. :| As I imagine... very few people are.
