From the Japanese comic "Day on Campus".

It comes from the famous saying when Katsura Yanha stabbed the world of Saionji in the finale and cut open her belly to see if there was anything in the uterus, because Saionji killed Ito Makoto (Brother Stallion Makoto) ), so Gui Yanye killed Saionji. I heard that TV Tokyo stopped broadcasting the day school because of this plot, and played the game's BGM when that time came. In the end, Gui Yanye lay on a boat holding Cheng's head. Floating on the sea.
