Tsuwabuki Akihito

Японское имя:

石蕗 秋人

A genius and strategist of the Four Heavenly Kings, he was also Shizuru's former mentor. His unnamed Bubuki is a fountain pen that is able to turn what it writes into reality (such as writing "nothingness" (無 mu) would cancel out an attack), and produce a lazer blade. He previously formed Entei's right leg.
