Once every five thousand years, the twelve beast kings do battle to determine their places in the zodiac. That time has come once again, and the snake king Jaou has chosen Makabe, the "queen" of her school, to be his proxy in the upcoming war.

A two-chapter short series.

Masaharu Tsuchiya has just become a freshman in high school and he’s looking to make a change in his life. He wants to be more active and more involved in school life, since the only club he was a part of in middle school he just coasted through. He’d also like to get over his lack of social skills when it comes to women. However, in his future, he’ll soon be tossed into a strange and magical world full of dancing after he witnesses his school’s competitive dance club in action…

"Koganeiro" is about a group of high schoolers in their second year who are confronted with the possibly lifer-altering decision of what to do after high school.
