Chototsu no Gyō (猪突の形, lit. Way of the Boar Tusk) is one of the Ways of Ryūha Koei Sōgetsu. This method deals with body blows. It also involves swift movements like that of a charging boar.
- Retsuzan Kongō (裂斬金剛, lit. Adamantine Rending Slash): Rintaro focuses his energy into a close-range body blow and slams into the side of his target. The result is a heavy impact, sending his opponent flying away and causing shockwaves powerful enough to rip up the surrounding ground.
- Usain Bolt (超速雷電(ウサインボルト), lit. Super Fast Thunder and Lightning): Rintaro uses all his might to charge straight out of Nangokuren High School's gymnasium when the principal dismissed everyone like a boar charging towards its food or escaping a predator.
