Tsuna during his time of moving from Yamagakure to the outskirts of Kumogakure fought up against Asura. Asura attempted to steal Tsuna's eyes, stating Tsuna had been using them wrong, and that their true purpose was for controlling the world. During the trade of blows, Asura managed to place the Cursed Seal of the God Slayer. However, upon contact, Tsuna's genjutsu activated and binding Asura, allowing Tsuna to create a gap, and walk away from the scene.
