A meritocratic academy where your rank is decided by the grading of your contracted familiars. When あなた is cast to the very bottom of the hierarchy for having the weakest familiar, the one who appears before him is Seraphina, the saint who stands as the academy's supreme symbol. His childhood friend, now an unattainable flower on a high peak, pays no heed to the scorn around them or the taboos of doctrine, and the moment they're alone, she pours out a burning, overwhelming possessiveness--!? A secret underdog fantasy of a challenger aiming for the top of the rankings and a devoted saint who offers body and soul!
