Reisen Udongein Inaba 

A character from the Japanese game franchise Touhou and made her first appearance in the series’s 8th instalment Imperishable Night as the stage 5 boss. She is a rabbit from the moon and worked as a soldier before fleeing to Earth after the Great Lunar War. She currently resides in the game’s fictional world of Gensokyo and lives in Eientei located in the Bamboo Forest of the Lost. She works as a servant for both Eirin Yagokoro and Kaguya Houraisan often peddling medicine for Eirin or doing other manual labor.
She also works with Tewi Inaba who also lives at Eientei, however Tewi is often depicted as rather disobedient to Reisen and often pulls cruel pranks on her (poor Reisen).

She has appeared in other entries in the Touhou franchise with the most significant being her appearance as a playable character in the series’s 15th instalment, Legacy of Lunatic Kingdom. She gains a new appearance and is given her iconic bunny megaphone. She is often associated with this game’s antagonist Junko and is depicted as the victim of a very Junko.

Reisen has also been included in many ship pairings between characters. Her most popular are her ships with Junko and Youmu Konpaku (and occasionally Eirin or Kaguya).
Reisen has also received lots of merchandise and has had 2 official Fumo releases as of 2025. She is also included in the Touhou mobile/spinoff game LostWord.

For those who are fans of Reisen, she is the very reason for our existence. Reisen is love and Reisen is life.
The girl with the purple hair and bunny ears is Reisen Udongein Inaba!
I love Reisen (she is best girl!).
That person is cosplaying Reisen (a true GOAT).

Reigen Arawakan 

A horrible misspelling of Reigen Arataka. You probably typed this in as a mistake, but now look what you’ve done. You’ve created a monster. Reigen Arawakan will always live knowing he was a mistake. Nobody loved him. How do you feel now, hm?? Maybe check your typos before you search stuff.
Reigen Arawakan: I am not a psychic and I don’t live in the 21st century. I am normal and I am not a tumblr sexyman.

Sister: This meeting was to discuss the rough draft of my essay, where we discussed the subsidiary questions I added in my rough draft. We also discussed the relationship between my main title and the real-life situations I chose to use in my essay. We discussed the structure of my essay as well, specifically the Math AOK section and how it relates to the contradiction of the title. This second meeting was particularly helpful in discussing the implications of my essay claims and how to apply the title across various areas of knowledge. There were many sections of the essay that could have been cut down in wordiness and the ways of knowing required further and more in-depth analysis.
