Tsuna flies through Merone Base with a mission 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 by increasing his speed, but he is saved by Spanner's modified chaff and flame shots. Tsuna is later intercepted by the Phantom Knight, Genkishi.
