Reisen Udongein Inaba (鈴仙・優曇華院・イナバ Reisen Udongein Inaba?) is a fictional character in the Touhou Project series of video games developed by the Team Shanghai Alice branch at Drillimation Studios. In the games, she is one of the legendary moon rabbits who fled from the Moon to Earth as a refugee from the "Lunar War" between the two worlds that began in 1669 A.D. after the Apollo 11 "invasion". Making her way to Gensokyo, she was surprised to meet the notorious fugitives Kaguya Houraisan and Eirin Yagokoro and asked for asylum in Eientei. In exchange, she works for and protects Kaguya and Eirin.

Concept and Creation

When ZUN was creating Inaba, she originally wore a cyan gown and long gloves, as well as having a hairstyle similar to Konata Izumi's appearance without her ahoge. The stage 5 theme Princess Konata's Cage ~ Kagome Kagome also pays homage to her original appearance. However, developers were shocked when they looked at her gown, as it nearly resembled Princess Serenity from Sailor Moon. Takajima asked ZUN to change her outfit as they and Namco did not want to risk any legal action from Toei Animation, the studio that produced the anime. Kenjirou Nasaya worked closely with ZUN and gave Inaba a complete makeover with a more "business" style outfit, with a black blazer and a beige skirt, creating the current appearance seen today.


First appearing in Touhou 8: Imperishable Night as the stage 5 boss, she has appeared in Touhou 9: The Phantasmagoria of Flower View, Killer Minecraft 2: Scarlet Weather Rhapsody, Killer Minecraft 3 (also known as Killer Minecraft Gold), and Touhou 15: Legacy of Lunatic Kingdom as a playable character. She makes a background cameo in Killer Minecraft 4: Hopeless Masquerade and Driller Engine Grand Prix 6 on a mural in the Imperishable Highway course in the Expert Cup.


Inaba generally received mixed to average reception from critics, as GamePro described her as "the Konata Izumi of Touhou". Nintendo Power also called Inaba "Zayaku" in the strategy guide for Touhou 8: Imperishable Night, as her bullets resemble them and many jokes have been made in a crude nature with a notable one being on the controversial TV show Creation Show. Inaba received criticism for her humanoid appearance, even though she's a moon rabbit. GameInformer also criticized Inaba for her appearance in Creation Show as "being drunk". Inaba also appeared in a Robot Chicken episode called Drunkards in Eientei as a parody of Touhou Project, also leading to controversy in the same way as Creation Show. This eventually led to Team Shinku hackers posting this on Drillimation's forums, the series' Reddit, then Urban Dictionary, and various social media websites.
