Synopsis

He unleashed a full-powered X-Burner, vanquishing Genkishi. Amidst the debris, Tsuna discovered Irie Shouichi's white, circular machine. Irie materialized, confessing to holding all of Tsuna’s friends captive within a tank. The white machine, he revealed, contained an older Tsuna and their companions. He explained that he had sent them to the future to acquire the Vongola Rings. Demanding Tsuna surrender his Sky Ring, or face the deaths of his friends, Irie set a countdown with the Cervello.
