The secret to Genjuurou's strength: Eating, sleeping and watching movies.
Chris's very Magical Girl-equse transformation in episode three. Not to mention the lyrics of her song.
Rather than a greeting I'll give you my gattling. You're just trash that deserves a good trash burning. 1, 2, 3 You're an eyesore!
Genjuurou randomly breaking into song during the training sequence in episode 9, with Chris playing the Straight Man the whole way through. And Chris completely sucking at the training despite being the most Hot-Blooded girls.
Made even more hilarious when that song is "Ying Hung Gu Shi (Cantonese: Hero's Story)", the main theme for Police Story, originally sang by Jackie Chan, with Chris' comment in the background is basically saying "Won't we get into copyright infringement with this song?"
The training montage itself. Tsubasa is in her own pace, Hibiki is giving it her all, while Chris is...borderline keeping up and failing in almost all of it.
In Episode 10, Hibiki goes "I'll bring back Miku even if I die!" -"You're not allowed to die!" -"Then I'll come back alive even if I die! I swear!" to a baffled Genjuurou, who honestly can't answer anything to that.
Ending montage. Tsubasa complains that Chris isn't calling her 'senpai' anymore, so Hibiki teases her... which led to Chris exploding and reminding her that she is Hibiki and Miku's sempai.
