Koikyuu
From Broccoli: Violation of the rules in the love game! When you are Cupid in training, you must follow the rules: do not communicate with your goals. Do not associate with the enemy. Practice archery every day. Maybe if someone said Koi, Ai and Ren, they could not get into trouble. Girls are trying to finish their missions by the rules, but there is always something that stands on their way.
