Sushi Kokuu Hen (Japanese: 寿司 虚空編) is an educational Japanese webcomic about googology, drawn by Doom Kobayashi (Japanese: 小林銅蟲). It has attracted considerable attention for its surreal atmosphere and "overwhelming incomprehensibility."
The comic began on September 11, 2013, and the first six episodes were published in the U-2 league of Shogakukan's Ura Sunday, which shut down at the end of 2014. It restarted on April 13, 2015, on Pixiv, where episode 7 was published with translations to English, Simplified Chinese and Traditional Chinese. Episode 7 of “Sushi Kokuu Hen” has the same content as episode 6 of another pixiv comic, “さいはて -Daydream Attractor-”.
It was published on August 10, 2017 by Sansai books in Japan.
The story begins with the explanation of Graham's number. The title of the comic is "Sushi", and the readers expected to read story about sushi, but the first story was unexpectedly all about math. As the story goes on, more advanced topics of googology, such as Fish numbers and chained arrow notation are presented.
