The Hyoho Niten Ichi-Ryu (兵法二天一流) is a school founded by Syuusuke Maruyama, whom wanted a place to teach aspiring fighters different fighting styles. One of Syuusuke's goals is also to make majority of his students learn to follow the code of bushido. When ready, he would teach them the swordstyle known as undefeatable, the Toko Niten Ryuu (常二天流, Infinite Two Heavens Style), a style created by Syuusuke, after he learnt the Niten Ichi-Ryu (二天一流, Two Heavens as One Style) and changed it to fit his fighting style. Syuusuke also teaches the Niten Ichi-Ryu to people who are able to pass one out of the three tests they have to take before being deemed as worthy. The academy's location is currently unknown.
