This is the mahjong club at Kiyosumi High School ten years ago.
This is the story of how the famous semifinal match from ten years ago was changed.
This is a changed world, with one extra transmigrator in it...
Except that superpower mahjong is one thing that can't be changed ╮(￣▽￣")╭
P.S. The author's mahjong rank is pretty average, so I'll do my best to make sure everyone can follow along.
My own settings take precedence. These include Kenzaki Kyouka being a first-year student, Kiyosumi still being a student council ten years ago, and the existence of seven crowns and world ranking tournaments.
Also, the mahjong matches in the story come from Riichi City game records and superpowers provided by the author and group members. Many thanks [wait, what].
