The beloved comedy anime series 100 Girlfriends (The 100 Girlfriends Who Really, Really, Really, Really, Really Love You) has added a big name to its third season cast. According to Anime News Network, legendary anime voice Rie Kugimiya will voice Yaku Yakuzen, Kusuri's grandmother and one of Rentarō Aijō's new girlfriends.

Rentarō, a high school student constantly rejected in love, encounters a love god and learns that he has exactly 100 soulmates in his life. The anime adaptation, produced by Bibury Animation Studio, aired its first season in 2023 and its second in 2025. The third season continues by adding a new name to Rentarō's soulmate list with each passing episode.
For manga readers, Yaku Yakuzen's inclusion in the story shows that the series' classic formula of every girlfriend has her own unique quirk continues. Having such a close relative as Kusuri's grandmother on Rentarō's love list is also proof that the series knows no bounds. A star voice like Rie Kugimiya joining this crazy cast highlights how ambitious the third season's voice performances are.
It's already a matter of curiosity which other familiar voices will join the cast in the upcoming episodes. 100 Girlfriends fans can't wait to hear Kugimiya's take on Yaku Yakuzen in episode 8. Given the series' pace and expanding cast, it's safe to say many more surprises are on the way.
