It also goes behind the series: One's original 2009 webcomic and the pun in its Japanese title, how a hospitalised Yusuke Murata came to redraw it, the Madhouse first season and the criticised J.C.Staff second, JAM Project's openings, the voice actors, the games, the Overwatch crossover and the long-gestating live-action film. Difficulty runs from easy questions any anime viewer can answer to expert questions for readers of the manga.
