, better known by his pen name, is a Japanese manga artist. Sakuishi has a wide variety of interests which include baseball (he is a huge Chunichi Dragons fan), martial arts, MMA, and music (he is a huge Red Hot Chili Peppers fan). Each of these has become the basis for his most popular series (baseball in Stopper Busujima, fighting in Bakaichi, and music in Beck). His series also often include character cameos from his past works; one of the newspaper reporters in Beck is actually from Stopper Busujima and so on. Additionally, he's a big fan of Sangokushi (Romance of the Three Kingdoms) with an altered version of that story appearing in Beck written by "Christy Sakuishi". In Beck he included many famous people in background crowds. These included many popular musicians, characters from Happy Sangokushi and MMA legends Royce Gracie and Kazushi Sakuraba.
