Reisen Udongein Inaba

Reisen's Personality: Despite her insanity-inducing abilities, she is actually a rather balanced and thoughtful individual. She has a high level of generalized anxiety, and appears to be constantly afraid of being punished by her superiors, as seen in her bad ending of Legacy of Lunatic Kingdom. This may be due to her history of being a slave in the Lunar Capital and a contributing factor to why she fled in the first place. Despite her relative degree of freedom while living at Eientei in Gensokyo, she still desires to make herself useful to others as much as possible, even at her own personal expense.

Reisen's Appearance: In Imperishable Night Reisen has red eyes, long light-purple hair and long rumpled rabbit ears - like all members of the Lunar Defense Corps, her ears stand up straight and are decorated with two accoutrement-like buttons. Her outfit consists of a long-sleeved black business suit over a white shirt, along with a beige skirt, white socks and red shoes. Her left lapel is decorated with a crescent moon-shaped insignia, and a pocket square in her left shirt pocket.

Reisen's Manipulation of Wavelengths/Insanity: Reisen has the ability to sense and manipulate waves of all kinds, her red eyes often acting as a means of inducing insanity. Her signature use of this ability is manipulating another person's perception to the point of inducing madness or hallucinations depending on the strength of her opponent's will. By increasing the frequency of brainwaves she can make a person short-tempered and irrational, or by reducing them can leave her target apathetic and depressed. Reisen can also manipulate light and sound waves to deceive the senses such as by concealing the paths of her danmaku, to creating after-images of herself, to casting wide-area illusions that cause people to get lost. Finally, she is capable of releasing waves from her eyes in a destructive blast. Reisen is immune to the abilities of the Three Fairies of Light (seeing an invisible Sunny Milk, hearing a silent Luna Child and escaping Star Sapphire's detection) since they are based on waves, though she seems unable to replicate Star Sapphire's abilities with her own.

Reisen's Moon rabbit abilities: Moon rabbits can send "ESP waves" and receive them with their ears, forming a sort of psychic network where they share feelings and rumors. Reisen can still participate in this network despite the physical and spiritual distance between Gensokyo and the Moon.

Reisen's Occupation: Formerly Reisen was a Moon Rabbit in service of the Lunarians. Moon Rabbits are seen as tools by Lunarians and are used for a large variety of menial labour including farming, pounding medicine, cleaning and as soldiers in the Moon's war effort. However, sometime in the Lunar War, Reisen deserted the Lunar Capital and fled to Earth. After seeking refuge from Eientei, Reisen now serves Eirin and Kaguya. She effectively performs as their housekeeper doing manual errands for them. Eirin operates as Reisen's mentor in medicines. She also sends her to the Human Village where she sells medicine to humans at an affordable price.

Reisen's Megaphone-shaped Handgun: Starting with Legacy of Lunatic Kingdom, Reisen equips a handgun in a shape of a megaphone. She uses to fire bullets and mainly soundwaves at her foes. It can change the size to function as a shotgun and even use like a real megaphone. Reisen has two in her possession which she dual-wields.

Reisen's Species: Throughout the Touhou Project, she is always referred to as a moon rabbit. However, in Legacy of Lunatic Kingdom, Reisen realizes that living on Earth for too long has tainted her with impurity. This allows her to save the Lunar Capital, as only someone with impurity could face Junko, the game's primary antagonist. Knowing that she can no longer return to the Lunar Capital or being a moon rabbit again, she now proudly proclaims herself to be an earth rabbit of Gensokyo.
