Aijou Rentarou

Rising high school student Aijou Rentarou had lived a life of heartbreak, having just gotten his 100th rejection from a girl he confessed his love to. Upon visiting a love shrine and praying to receive a girlfriend, he was told by the god of the shrine that he was destined to meet not just 1, but 100 soulmates during his coming years in high school. However, any soulmate that didn’t fall in love with him and be happy would die a cruel death. Despite the seemingly insurmountable odds laid in front of him, Rentarou set out to accomplish the impossible task of dating 100 girls at the same time. Little did he know that his love for his girlfriends would unlock his potential, granting him superhuman abilities. At the time of this post, Rentarou currently has 27 girlfriends who all have assembled into a friend group, forming connections with not just Rentarou, but each other.
