The moon drives people mad. So, I wonder if you can remain in your right mind while gazing into the eyes of this lunar rabbit?

Reisen Udongein Inaba (鈴仙・優曇華院・イナバ) is a moon rabbit who deserted the Lunar Capital during the "Lunar War" that began in 1969, after the Apollo 11 "invasion". Arriving in Gensokyo, she stumbled upon the infamous fugitives Kaguya Houraisan and Eirin Yagokoro, and in exchange for asylum in Eientei, she swore loyalty to them.

Weaknesses: Reisen is vulnerable to spiritual attacks.

Notable Attacks/Techniques:

  • Lunatic Red Eyes: Through her Lunatic Red Eyes, Reisen has the power to sense and manipulate waves of all kinds. Her signature use of this power is, through establishing eye contact, manipulating the brain waves of her opponent to drive them insane, causing hallucinations. She can leave her opponents short-tempered and irrational by increasing the frequency of brain waves, or leave them apathetic and depressed by decreasing them. Reisen can also manipulate light and sound waves to distract the senses of opponents indirectly, concealing the paths of her danmaku, creating after-images of herself, and casting large scale illusions. Reisen is immune to most abilities based on waves, as well, such as the powers of the Three Fairies of Light, and can even spot individuals that cannot be picked up by normal means, such as Koishi.
  • Moon Rabbit Powers: As a moon rabbit, Reisen can send and receive ESP waves through her ears, transmitting rumors, emotions, and thoughts to other moon rabbits. Though she is far from the Moon, both spiritually and physically, she can still participate in the psychic network of the rabbits on the moon, though she tends not to.

Skill Cards:

  • Ocular Spectrum: As Reisen dashes forwards, her position is obscured by a slew of illusionary duplicates.
  • Ripple Vision: With a glare, Reisen fires a ring-shaped wavelength that expands over time.
  • Ultrared Field: Reisen creates a wavelength conversion field that disturbs the vision of those within it, making it difficult for them to land attacks.
  • Ultraviolet Field: Reisen releases a wavelength that disturbs her opponent's mind, causing them to see things that aren't there.
  • Undersense Break: A short-range wavelength that damages those who get too close.

Spell Cards:

  • Charming Look "Corolla Vision" (Disjointed Circular Corolla): Reisen releases large rings from her eyes that grow larger the further they travel.
  • Empty Heart "Discarder" (Scars of an Empty Heart): Reisen fires a powerful bullet that deals spiritual damage.

  • Illusion Bomb "Mind Starmine" (Myopic Firework): Reisen curls in on herself before releasing a burst of shots in every direction.

  • Poison Smokescreen "Orb of Gas-Treated Weave": Reisen throws a flask containing a drug that reacts with the air to become poisonous, draining the life of her opponents while she is unaffected, as she has already taken the antidote.
  • Red Eye "Lunatic Blast" (Viewing the Circle Moon): Reisen fires a powerful laser of concentrated ESP waves skyward. While she could use this to contact moon rabbits from Earth, she does not do so anymore.
  • Shortsight "X-Wave" (Ultrashort Brainwave): Reisen shorts out her opponent's mind with a special wavelength, driving them insane and causing them to see multiple hallucinations of Reisen that can still harm them.
  • Weak Heart "Demotivation" (Empty Heart, Empty Mind): With a short-ranged burst of her eye beams, Reisen shocks her opponent and makes it difficult for them to focus or use more powerful techniques.
