Synopsis
Spanner works on Tsuna's Contact Lenses while Tsuna fights the Deadly Stem Force. Iris Hepburn uses her Cloud Whip to merge the Death Stalk Unit members, but Tsuna breaks them apart with his technique X-Stream. Ginger Bread's doll arrives to help Iris fight Tsuna. Spanner completes the contacts, but he is knocked out by falling rubble. As Spanner falls, he tosses the box with the contacts to Tsuna. Iris and Ginger Bread's doll attack Tsuna, but he blocks the attack. He then emerges from the explosion with his contacts and X-Headphones activated, ready for Operation X.
