Thouser/Amatsu Gai: Running for Student Council President. Has perfect scores in pretty much everything.

Genm/Dan Kuroto: Also running for Student Council President. Bit of a god complex, and a little unhinged, but he's not too bad once you get to know him, most of the time...

Gaim/Kazuraba Kouta: Member of the dance club, sometimes goes out of his way to help others in need.

Grease/Kazumi Sawatari: Delinquent with an obsession for Idols. Tends to get into a lot of fights.

Cross-Z/Banjou Ryuuga: Member of the boxing club. Gets blamed for beating people up sometimes, isn't very smart, and great at physical activity.

I like to imagine a scenario where Aruto gets elected Student Council over Genm and Thouser.
