Fun fact about this episode:
Those Gunpla that Chinan and Mao had at the very end?
They're actually custom Gunpla created to promote Gundam Breaker by Komatsu Mikako and Kokuryu Sachi, aka the VA's for Sei and Reiji respectively.
Komatsu Mikako's is the pink one on the left, which references Moretsu Space Pirates.
