Ep. 422: The One Who Will Inherit
Konohamaru cleans Naruto's apartment and sees him returning home after training. Keeping his normal clothes on, Naruto teaches Konohamaru how to use the Rasengan. While Naruto leaves to rescue Gaara from the Akatsuki, Konohamaru has trouble with his first phase of technique training and improves with his Sexy Jutsu. Using sexual women magazines as a consequence to Ebisu's distress, Konohamaru mastered Naruto's first lesson. Naruto returns and gives Konohamaru a rubber ball for his second phase of training, before leaving the village again to find clues about Sasuke. Konohamaru gets Ebisu's unusual help and reaction along with his teammates, but fails to complete training with the Rasengan.
