Voice Actor:

Trina Nishimura


Utsuho Reiuji is one of Satori's pets, a Hell Raven who has lived in the underground world since before it was separated from Hell. Her job is to regulate the flames of the Hell of Blazing Fires. she was told by a voice (presumably Kanako's) that she could swallow the god, Yatagarasu, that was hidden in the flames to gain a power that would fulfill the wishes of both the worlds below and above the surface. This power was nuclear fusion. Utsuho misunderstood what the voice had told her, and decided that, using these powers, she would take over Gensokyo. Her friend, Orin, became worried about Utsuho, and drove evil spirits to the surface to cause an incident among the strong youkai above ground, in hope that they would come down to do something about it and, when they got there, defeat Utsuho and bring her back to her former self. What came, however, was not a strong youkai, but a strong human.


Skill CardsEdit

  • Ground Melt: Utsuho fires a laser at the ground, causing it to melt and deal damage to opponents on the ground.
  • Hell Geyser: Utsuho slams her cannon on the ground, causing a lance of nuclear energy to jut up from the earth.  
  • Radiant Blade: Utsuho charges forward, surrounded by a yellow glow. Once her charge has ended naturally or she contacts an opponent, she then immediately lunges back and fires a 3-hit blast with her cannon.
  • Flare Up: Utsuho summons 2 plasma balls from the ground around her, which spiral upwards.
  • Rocket Dive: Utsuho propels herself forward using nuclear fusion and attacks.
  • Melting Pummel Kick: Utsuho lunges forward with her left foot raised, surrounded in nuclear flames. If she touches the enemy, she then slams them down and proceeds to roast them with aforementioned flames, kicking them aside with her concrete foot afterward.
  • Retro Atomic Model: An energy ball spins and follows Okuu. The ball itself can be used as a shield or a weapon.
  • Vengeful Nuclear Spirits: Utsuho summons a floating radiation warning sign with the Light button. Upon using the hard button, the sign then fires a series of bullets in the opposite direction of wherever Utsuho is relative to the sign.
  • Shooting Star: Utsuho flies slightly upwards as she summons pairs of plasma balls above and below herself, which arc outwards after a short period of time.
  • Break Sun: Utsuho creates a sun-like object above her head, and pulses light particles at the enemy. Holding the button down will make the attack stronger.
  • Shooting Sun: Utsuho conjures a small fusion ball over her head before tossing it in front of her. Holding down the buttons makes the ball float higher over Utsuho's head, causing a farther shot when released.
  • Hell Wave Cannon: Utsuho conjures four balls of very dense nuclear energy in front of her. Letting go of the button causes her to hurl all four of them forward. Holding the button causes all four balls to gradually spread out and change the angle of fire. Holding the button for the entire duration causes the orbs to instead fire lasers that go all the way across the screen.

Spell CardsEdit

  • Fixed Star: Utsuho throws a ring of nuclear energy at the opponent. The energy ring moves backwards after a while, and hits the enemy a second time.
  • Geothermal Sign “Nuclear Blaze Geyser”: Utsuho channels nuclear energy into the ground, releasing a series of powerful energy columns that knock her opponent away from her with great force.

Last WordEdit

  • Giga Flare: Utsusho shoots a beam at the enemy. If it hits the enemy, the enemy will be trapped in a nuclear sign, which will eventually explode.


  • Battle Intro: She flies in and says "Witness the power of nuclear fusion!"
  • Taunt: She stands in place, with a question mark above her head in a thinking pose and says "Unyu?".
  • Victory Pose: She says “Nobody can withstand the ultimate energy!” and raises her cannon while Rin Kaenbyou dances behind her.

(Utsuho returns to the Hell of Blazing Fires and greets Rin Kaenbyou.)

Utsuho: I'm back, Orin!

Rin: Welcome back, Okuu! Congradulations on defeating Fafnir!

Utsuho: Thanks! Hey, I just wanna say, I made some new friends and they're coming over!

Rin: Oh, how exciting!

(Various Capcom monsters enter. Among them include Nemesis, Firebrand, The Yellow Devil, Hauzer, Bishamon, Yami and Adam the Clown. Rin looks a bit scared.)

Rin: Uh....These are your friends....?

Utsuho: Sure are! Something wrong, Orin? You look a bit nervous....

Rin: Uh, nevermind! I'll go inform Satori-Sama!
