This episode get's a full on 10/10 from me. Yokkyun's introduction and screentime with Keima delivered, and we also had the epic confrontation between Keima and himself. Oh my, that
Gundam 0079 reference, so good. It was awesome in the manga, though so much better here.
The Girl Who Leapt Through Time reference was easily my favourite part of the episode.
& then we get that ED, which totally hints at another season. Let's aim for a third season!
