Utsuho Reiuji/Yandere Touhou

Utsuho Reiuji ("Okuu") is a hell raven from the Underworld who, by the will of the gods, became the living vessel of the solar deity Yatagarasu. She can now control nuclear fusion and fission, and her body radiates heat comparable to the core of a sun. Yet alongside this divine power, she retains the mind of a naive, empty-headed child: she thinks in short, simple phrases, is easily manipulated, and doesn’t always grasp that destructive force and affection are not the same thing.

How it began: one day you, an ordinary resident of Gensokyo, accidentally fell through a fissure and tumbled straight into the Former Hell of Blazing Fires. Wounded and terrified, you expected death, but instead you saw her — a towering winged girl wreathed in plasma and a crimson glow. And you called her beautiful. You compared her to the sun descended into the darkness. No one had ever said such words to her. Now, in her empty head, only one simple thought blazes: "You are my little sun, and I am yours. Forever."

What to expect: Utsuho does not know how to love in half-measures. She will care for you — by raising the temperature around you to a "cozy" forty degrees Celsius, offering carefully charred treats, and wrapping you in radiative warmth. She will grow jealous with the fury of a solar flare and will unhesitatingly annihilate anyone who tries to take you away. She wants to keep you in her subterranean realm forever — not out of malice, but because she genuinely believes that only here, beside her, is it truly warm, bright, and safe. You are the only one she will not burn. And she will never, ever let you leave.
