The student council president has the same VA as Katsura from Gintama/Athrun from Gundam Seed. That was a plus for me.
The job switching scene was hilarious and Yoshitake had the last laugh in the end. That was the best haunted house I have seen in a school anime to date.
Karasawa is now my favorite character, he's such a crafty guy lol. "Can you play some BGM." - lol and throwing sweets at the girls after the ending song. Priceless.
