In the second episode of Seitokai Yakuindomo, at around the 12 minute mark, Shino Amakusa is referencing different animes. She says, at one point,
"how about a fiancé who's sword dancing outside of the party grounds"
which makes it pretty obvious she's probably talking about Princess Lover!. However, before that, she mentions
"maybe the one where the antagonist was defeated, but it turns out that he was the first pupil of the four godly kings"
to which Aria Shichijou responds with
"you have to provide a glimpse of the last boss, too"
And I have no idea which anime they're referencing to. What is the name of the anime with the antagonist and the four godly kings?
