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 (霊烏路 空, Reiuji Utsuho) is one of Satori Komeiji's pets, a Hell raven who has lived in the underground world since before it was separated from Hell. During the events of Subterranean Animism, Kanako speaks to her in her sleep, telling her to swallow the sun god Yatagarasu to gain its powers and fulfill the wishes of both the surface and subterranean worlds. Utsuho misinterprets Kanako's intent, and decides to use her powers to conquer Gensokyo.

After her defeat, she returns to regulating the flames of the Hell of Blazing Fires, and aids in providing energy to the Underground Geyser Center, through the Nuclear Furnace.

Powers and Stats

Tier: 4-C

Name: Utsuho Reiuji, Okuu

Origin: Touhou Project

Gender: Female

Age: Unknown

Classification: Hell Raven

Powers and Abilities: Superhuman Physical Characteristics, Flight, Danmaku, Nuclear Fusion and Fission Manipulation, Resistance to intense temperatures, Regeneration (Low-Godly. Can regenerate solely from her Non-Corporeal "mind"), Resistance to Mind Manipulation (As a youkai, she should be able to resist the effects of the moon, which can drive normal humans insane and kill them just by looking at it)

Attack Potency: Star level (Absorbed the powers of Yatagarasu, and is capable of using its powers. It is stated by Kanako that she is a highly efficient host for Yatagarasu. Furthermore, releasing its power is much easier than containing it.)

Speed: Massively FTL+ (Superior to high tiers)

Lifting Strength: At least Class 5 (As a Youkai she should be a lot stronger than a fairy like Cirno), possibly Class T (If she is able to move in her stars, she would have to be able to lift that much)

Striking Strength: Star Class

Durability: Star level (Capable of containing Yatagarasu's power)

Stamina: Superhuman

Range: Several 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 intelligence when it comes to everything else.

Weaknesses: She can run out of the materials needed for nuclear fusion. Vulnerable to spiritual attacks.

Notable Attacks / Techniques:

  • Manipulation of Nuclear Fusion: Through the left leg, right leg, and the right arm's third leg, Utsuho is capable of controlling the energy of nuclear fusion. Her powers come from the god of nuclear fusion, Yatagarasu, and she is technically her very own branch shrine of Yatagarasu. With these powers, Utsuho can create miniature stars and generate nuclear power. However, these powers are dependent on the atoms needed for the fusion process, so she cannot produce energy forever on her own.

Skill Cards

  • Break Sun: Creates a sun-like object above her head, and pulses light particles at the enemy.
  • Flare Up: Shoots nuclear radiation around which then ascends in a helix and burns enemies.
  • Ground Melt: Sears the ground using her control rod.
  • Hell Geyser: Creates a nuclear reaction underground and shoots the energy diagonally upwards at the enemy. Can also shoot towards the enemy from the back, so it's quite easy to try to use this skill in chains.
  • Hell Wave Cannon: Unleashes waves of light, then gathers and points them to fire in any direction she wants.
  • Melting Pummel Kick: Propels herself forward using nuclear fusion and attacks.
  • Radiant Blade: Charges up energy until she gets close to the enemy and then fires it at them.
  • Retro Atomic Model: An energy ball spins and follows Okuu. The ball itself can be used as a shield or a weapon, and is an excellent tool for Okuu, whose moves are usually very wide and sweeping.
  • Rocket Dive: Propels herself forward using nuclear fusion and attacks.
  • Shooting Star: Moves diagonally upwards and leaves a trail of energy balls behind her. They begin moving outwards after a short time delay. She has no idea she's attacking, she just thinks she's moving.
  • Shooting Sun: Collects nuclear energy over her head and throws it at the ground. She can collect energy for as long as she wants, and the projectile is not affected by other bullets until it explodes.

Spell Cards

  • "Abyss Nova": A nuclear chain reaction occurs within Okuu and destroys everything in sight once critical mass is reached. The explosion has a large hitbox and can not be blocked. An intensely hot skill, even for her.
  • Atomic Fire "Uncontrollable Nuclear Reaction Dive": Propels herself using a massive amount of fusion energy in this massive attack. Races back and forth across the screen many times to hit the enemy in multiple places.
  • Blazing Star "Fixed Star":' Throws a ring of nuclear energy at the opponent. The energy ring moves backwards after a while, and hits the enemy a second time.
  • Blazing Star "Ten Evil Stars": A ball of nuclear energy attacks along a set orbit.
  • Control "Self Tokamak": Fusion energy surrounds Okuu and activates when she flies or dashes forward towards the enemy. Requires precision, so a bird-brain like Okuu can't think of any other attacks when attempting to use this one.
  • Crow Sign "Yatagarasu Dive": A fusion reaction occurs within Okuu, and a silhouette in the shape of a brilliantly shining bird attacks the enemy. A skill that shows the true spirit of the hell crow.
  • Explosion Sign "Giga Flare": Collects a huge amount of nuclear energy and burns everything in front of her. Extremely powerful with a huge range, but Okuu is completely exposed from the back.
  • Explosion Sign "Mega Flare": Collects nuclear energy and fires. A very simple and high-powered move.
  • Geothermal "Nuclear Blaze Geyser": Infuses the ground with nuclear energy, turning the ground to magma and spewing it everywhere. New magma spouts erupt from locations where magma landed.
  • "Hell's Artificial Sun": Creates an energy mass that has gravity, and shoots it forwards. She will continue to inject energy into this mass.
  • Light Cover "Nuclear Heat Visor": Creates a barrier in front of herself, which can take a few attacks. Will continue to be in front of Okuu until a certain amount of time passes.
  • Light Energy "High-Tension Blade": Creates a blade-like energy beam from Okuu's control rod. Limited range, but if used at close range, the move covers quite a large area.
  • Nuclear Sign "Creeping Sun": Creates a nuclear reaction in the sky and sun-like projectiles shoot down from the heavens as a result of the nuclear reactions.
  • "Subterranean Sun": Draws energy from the earth and creates a sun on the spot. The sun manifests itself and burns everything in the surrounding area.
