Renai Banchou! Inochi Mijikashi, Koiseyo Otome! Love is Power

The heroine has watched everyone around her find their person, and she is tired of waiting. School legend says that tying a yellow handkerchief on the school rooftop will summon a Ren'ai Banchou to help with love troubles. She ties seven of them, possibly out of frustration, and seven Ren'ai Banchous arrive. Perhaps one of them is the destined match she has been looking for.
