Somnolent

Ayumi is your typical Kingdom Hearts weeb with anxiety and depression, so naturally, when her best friends all sign up to go to an exhibit at a Biology Research Center, she doesn't really want to go. At all. And while she was actually just too nervous to think about the future for more than a second, there were more things she should have been worried about.

She ends up as Nobody, Miyuxa, a member of Organization 13. Due to her foreknowledge of practically every event in the kingdom hearts series, Xemnas appoints her to a high inner rank, being the consultant for all decisions made by the organization in an attempt to create a more favorable outcome for the group.
