Episode 13

Groovy Mix is the thirteenth and final episode of the anime D4DJ First Mix. It aired on January 29, 2021.

Overview
The only thing that stands between Happy Around! and victory is Peaky P-key. Do they have what it takes to come out on top?

Summary
Happy Around! is pitted against Peaky P-key in the Sunset Stage's first round, to the former's dismay before being motivated as it is their best opportunity to face the latter. The group continues practicing at Rinku's house, where they reminisce about their formation, and attends the Yoba Festival, where Maho openly challenges Shinobu ahead of their competition. The two units perform new songs and Peaky P-key advances, eventually going on to win the tournament. After the Sunset Stage, Happy Around! further recalls their journey before being invited--along with Peaky P-key--to an after-party held by Photon Maiden.
