Kaguya
Kaguya's one of those characters who's shrouded in mystery—literally came from the moon, which is pretty much the most dramatic origin story you can have. She's got this whole mad scientist aesthetic going on, complete with the unhinged energy that comes with it.
Her main role in the story is being the guardian of the Michimi Peach shards, which is a pretty serious responsibility. Fans often note that her lunar origins add an otherworldly vibe to her character that sets her apart from everyone else.
