Hikari and Kei were challenged by the student council president to a pro-wrestling showdown but they were cheated when Hikari and Kei got handcuffed. That didn’t let them lose and SA ended up as victors..
I think there’s nothing special about this episode and the comedy is totally lacking something… and that repetitive “Ni-san” joke is already getting old and corny. I also find Kei’s character design…um…bad compared to the manga because he really looks good there. Last but not the least, the OP theme… I wonder why Yuko Goto’s Mikuru voice is singing it. It’s just too…Mikuru-ish(HORRIBLE in other words)..
