Kyoya Hibari vs. Phantom Knight
Hibari simultaneously inserts 3 Rings into his Cloud Hedgehog Box Weapon. Genkishi's Mist Slugs are pushed aside by the Reverse Needle Sphere, leaving only Genkishi and Hibari. The two attack each other in an airtight deathmatch arena. Elsewhere, Spanner and Tsuna are cornered by Iris and the Death Stalk Unit. Iris whips the Death Stalk Unit with her Cloud Whip, and they grow to immense sizes because of the Cloud Flame's Propagation characteristic. Iris calls them her "reinforcements".
