It was shochu.

I LOVE this ending. It was perfect. It's been a while since I've seen such an excellently executed exit (alliteration intended). Everything that has happened so far culminated into the conclusion. The harem end was the best part. The two girls love each other anyway and are evidently willing to share. Top dogs deserve that kinda perk.

I love Iris's jealous face. That alone made this show worth it.

The only thing that could have made this final episode better was an announcement of a second season. Kazuhisa did stop the father from interfering, after all. Taking over the world with those two girls by your side and an engineering genius behind you is gonna be awesome. Oh, let's not forget megane shinobi under the desk doing you know what.
