Genkishi engages Tsuna in a battle using his hell ring, an armour and a special sword. Tsuna is at a disadvantage as he does not have much energy left due to firing the X Burner few times before. However, Genkishi wavers when Tsuna's resolute eyes reminds him of Uni. Tsuna then sets up a plan to absorb Genkishi's flames, and he regains his energy. Tsuna gains the upperhand and manages to overpower Genkishi.
