S04E98 — Declaration of War

Byakuran calls Irie and tells him that Mukuro has been defeated and that he was found to be transmitting data, possibly to the Vongola Tenth. Byakuran tells Irie that he is the most important person in that base and must escape if they invade the base. Irie for some hidden reason, can't leave. Irie calls all the Milliefore Japan members in the base and tells them he shall be leading the base now. The members are outraged and prepare to attack Irie until a swordsman by the name of Genkishi tells them anyone who opposes master Irie will be killed. Irie becomes the boss of the base. Afterwards the Vongola have received the data transmitted by Mukuro. In it was the picture of the white box Tsuna saw in his dreams. Training is resumed and Reborn gives Yamamoto a box about the sword emperor.
