Lord Yatagarasu, the Black Sun. Thank you for giving me your power. The sunlight that rains down on the Earth is a nuclear furnace that will create new atoms. My ultimate nuclear fusion will burn up every body, heart, phantom, and fairy!
~ Utsuho Reiuji


Utsuho Reiuji is one of Satori Komeiji's pets and the regulator of the flames of the former Hell of Blazing Fires. A Hell Raven, born from the darkness of Hell, Utsuho isn't the brightest, which made her a good subject for Kanako Yasaka's plan to gain the ultimate power of nuclear fusion. In her dreams, Utsuho was told to consume the remains of the sun god Yatagarasu, so she could fulfill the wishes of those above and below the surface of the world. However, she misinterpreted the message and decided that she would use her newfound, immense power to conquer all of Gensokyo and incinerate any who opposed her.

After having some sense "talked" into her, she returned to her previous job and is now using her powers to provide energy to the people of Gensokyo.

Attack Potency: High Universe level, possibly Universe level+ (Absorbed the powers of Yatagarasu and is capable of using them. Kanako has stated that she is a highly efficient host for Yatagarasu, and releasing its power is much easier than containing it. At least comparable to high tiers of Gensokyo such as Suika)

Striking Strength: High Universal, possibly Universal+

Durability: High Universe level, possibly Universe level+ (Capable of containing Yatagarasu's power)

Stamina: High

Range: At least tens of meters with Danmaku (Her firing range should be comparable to Sakuya's, who can throw knives at least 36 meters)

Standard Equipment: The "left leg of decomposition", the "right leg of fusion", and the right arm's "third leg"

Intelligence: Utsuho is very intelligent and knowledgeable when it comes to nuclear fusion and fission, but lacks knowledge when it comes to everything else, being somewhat oblivious, hard-headed, and naive

Weaknesses: Utsuho can run out of the materials needed for nuclear fusion and she is vulnerable to spiritual attacks

Notable Attacks/Techniques:

  • Manipulation of Nuclear Fusion: With the "left leg of decomposition", the "right leg of fusion", and the right arm's "third leg", Utsuho can manipulate the ultimate energy that is nuclear fusion. This power was granted to her by Yatagarasu, who she consumed, essentially becoming a shrine for the god. Due to her lacking intelligence, Utsuho makes for a perfect host, allowing her extremely efficient access to Yatagarasu's power, which allows her to draw upon atoms to use in nuclear fusion reactions and produce high amounts of energy and heat without pollution. While what elements specifically she uses for her nuclear fusion reactions are unknown, she implies that she utilizes hydrogen.
