While Tsuna and his family are observed by their respective Arcobaleno tutors, Collenello notices that Yamamoto is visibly disturbed by something. The first generation Rain Guardian, Ugetsu Asari, appears in front of Yamamoto and announces that his trial will take part that night at Nanimori Shrine. Yamamoto meets Asari and begins their trial. Yamamoto, blaming himself for their lost in the battle of Choice, fights Asari in an aggressive manner and seemingly defeats him. However, Asari announces that Yamamoto has failed the trial, saying that he is unworthy to inherit his power in his current state.
