Art by Lök Polymorfa:   / 1451759147062489089   Consider supporting me: https://ko-fi.com/umbrakinetic 八雲 藍 (Ai Yakumo) Ai Yakumo's theme: Morbid Curiosity for Another World ~ Astrofantasia Species: Youkai(?) Ability: Manipulating the Differences between Worlds The hidden younger sister of Yukari Yakumo that Yukari is prideful to admit she has one (Or admit that Ai is stronger). Normally reclusive under her sister's guidance, Ai watches everyday people go about their lives, and occasionally offers to give them the chance to abandon their current life to seek a better one in another world. However, if they take this offer, she won't allow them to ever go to their old world again. Ai is clumsy otherwise and, with the misguidance of her ability, may accidentally overwrite a world's history and perception. This can result in the addition, removal, and changes of any object, person, organization, and even landmasses of a world. However, she is ultimately altruistic, even if not completely understanding of herself or others' feelings at first. please help me this is a joke i took way too far
