La brava
A character in the season four of my hero academia with the quirk of love that is: the power to increase the power level of any one she loves. Gentle criminal fought against midoriya uses her quirk to strengthen himself. The whole heartfelt battle between midoriya and gentle criminal was based on how gentle criminal felt about La brava and his plans.
Initially la brava used to be some kind of secrete admire to someone in her class but when she was able to gather enough courage to send a love letter, her supposedly crush mocked her in her absence calling her a stalker, well to cut the long story short she met gentle crimal on the web during his usual live streaming and became his accomplice.
