After setting up their base, Shoichi guides Tsuna through the intercom where he runs into Torikabuto. Tsuna is seemingly overwhelmed by Torikabuto's attacks until he releases his box weapon, the Sky Lion Na-Tsu. Torikabuto surrounds Tsuna with projectile attacks and seemingly impales him in a sphere of needles. However, Tsuna transforms Na-Tsu into a cloak and wards off the attack.
