By all accounts, [Name] would probably have no problem at all completing this mission. They were dead, after all, they had absolutely nothing to lose.
There was only the little, tiny, concerning little detail that this dimension, in particular, contained every single person [Name] recognized, vaguely or otherwise, from various fictional mediums. Namely, video games.

In other words, another Fan![Name] but this time they're a genderless, very much DEAD soul who works with -- well, Yuuko Ichihara, from xxxHolic. Contains characters from KH, FF, TWEWY, and Link and Zelda from LOZ, the Vongola from KHR, maybe some Percy Jackson because why not? Anyway, it'll be a bang, folks. Poor, poor [Name].
