Marin and Wakana start to grow closer as he helps her create her cosplay. Though he's happy about the fact that Marin treats him the same way at school as anywhere else, he also starts to worry about the fact that other people think it's weird that they're hanging out. Despite that, Marin takes Wakana shopping so they can look for materials needed for her cosplay.
So I think we should go 
with this black violet...
...لذا أعتقد ينبغي أن نختار هذا البنفسجيّ الأسود
Deswegen fände ich
dieses Schwarzviolett gut …
Así que esta Black Violet…
Así que esta Black Violet…
Quindi potremmo prendere 
quella nera con sfumature viola...
Podemos pegar essa violeta escura.
