Ayumu and Yumina are at odds from the moment they first meet. They bicker endlessly, day after day, until finally Yumina goes too far and starts a fight just before a critical test. Her failure dooms her to repeat the year.

But just when it seems all hope is lost, a mysterious girl named Kurokawa Kirara appears and invites Yumina to run for Student Council President.

According to Kirara, whoever wins an Election War and becomes President will have the power to change any school rule he or she likes. Realizing that this is her only hope of becoming a senior, Yumina agrees to join the race, and drags Ayumu along for the ride!

Thus begins an epic tale of love and friendship in which youthful passions run high and debates shake the foundation of the heavens.
