A tremendously great novel written together with AI novelist-kun

Charlotte (?) the exchange student swears revenge on Ami-chan, a Kansai native who once became her fiancée, and settles everything through mahjong. Betrayal by allies, flying cheating, and finally emotion—will Charlotte be able to win through the high-stakes mahjong game?! This is a collaborative work between me and AI Verist-kun, but we didn't set strict rules and wrote it with total freedom. I'd say it's about 7:3 (Verin at 7 and me at 3). I wrote the cool lines, but Verin wrote the special techniques.
