The 100 Girlfriends Who Really, Really, Really, Really, Really Love You focuses on high school student Rentarō Aijō, who in his lifetime fell in love and confessed to exactly 100 girls, only to be rejected by all of them. While praying in a shrine, Rentarō is approached by the God of Love, who reveals that he, due to an error, is destined to have 100 soulmates. However, he also tells Rentarō that if he does not return the feelings of any of his soulmates, they will suffer an accident and die. Not wanting this to happen, Rentarō is determined not to let any of his soulmates die as he meets and dates them all at the same time.

Synopsis

Rentarō Aijō has confessed to (and been rejected by) 100 girls in his lifetime. On the last day of middle school, he visits a shrine and prays that he get a girlfriend during his time at high school. Suddenly, the God of Love appears and tells Rentarō that the reason for his non-existent love life is because everyone is only supposed to have one soulmate in their life, but due to an error on the God of Love’s part, Rentarō is destined to have 100.

Sure enough, on the first day of high school, Rentarō meets the wealthy Hakari Hanazono and tsundere Karane Inda. Both girls instantly fall in love with him, and Rentarō is attracted to both of them, but unable to decide between them. That evening, he visits the God of Love again and is informed that if he does not return the feelings of one of his soulmates, they will die in an accident. Not wanting such a fate to befall Hakari and Karane, Rentarō decides to date both of them at the same time, with their blessing. As the story continues, more girls are introduced and become Rentarō’s girlfriends, establishing a polyamorous relationship.
