Today's top could be tomorrow's bottom when playing the caste game!

School is hard enough as it is, but when students are forced to play a cutthroat game to determine their social ranks--and subsequent treatment--all bets are off.

Karino is growing closer to the increasingly vile Eno, and Azusa is spending more of his time with Daisho, a former student recently returned from a year abroad. But unbeknownst to Azusa, Eno is working on yet another twisted scheme. Karino doesn't want a repeat of the culture festival, but is it too late for him to right those wrongs and save Azusa?
