S7·E183 Aloof Cloud

Hibari's trial does not involve combat which causes Hibari to lose interest. Alaude, the First Cloud Guardian, tells Hibari he must demonstrate his worth as the Cloud Guardian to pass his trial and he has a day to complete it. While Tsuna and his friends try to persuade Hibari to take the trial to no avail, leaving only Ryohei to persuade him. During Ryohei's persistent way of persuading Hibari, Skull appears with a blimp and attempts to force Hibari to take the trial by attacking him. Hibari damages the blimp which causes it to begin its descent on the school.
