Tsuna, Gokudera and Yamamoto goes out of the hideout and to the outside. They try to find Kyoya Hibari but run into Lambo and I-pin protecting Haru Miura and Kyoko from two Millefiore Family members from Blackspell. Just as Future Takeshi Yamamoto is about to defeat them, a cloud of purple smoke appears and the past forms of Takeshi Yamamoto, Lambo, I-pin, Haru, and Kyoko appear.
