"Haneru and Dad's Stormy Summer Festival!"  

"Haneru to Tō-chan Haran no Natsumatsuri" (ハネルと父ちゃん 波乱の夏祭り) 

Haneru and his father Tetsuo argue with each other after Haneru refuses to take part in the family's traditional drumming for the annual summer festival. As both parties remain stubborn, losing focus as a result, Haneru, upon reflection, decides to put on a special Bon Odori for the festival, with Tetsuo as drummer.
