Tsuna flies through Merone Base with a mission and that mission is to find Shoichi Irie and the white, round device in his laboratory. Irie tries to interfere with Tsuna's movements by moving Merone Base's blocks. With Spanner behind him, Tsuna cannot shake off a homing missile, but he is able to fend it off with chaff and flame shots that Spanner modified. He is later intercepted by the Phantom Knight, Genkishi.
