That sounds vaguely indecent somehow. But uhhh I think more like Ibuki would insist on a birthday party to make up for all the ones he's missed, because cumulatively, it has to make up for a year/hour or whatever. Or possibly I am just really good at rationalizing BS reasons to torment people and I will shamelessly feed these to the relevant parties at the slightest provocation. Basically, I am a terrible person.
