The 100 Girlfriends Who Really, REALLY Love You Season 3: Voice Cast Updates

The fundamental creative team is intact, with studio Bibury Animation Studios returning to bring its characteristically bright, highly fluid animation style. The primary vocal cast is returning, alongside the formal introductions of the next wave of fateful soulmates:

The Main Roster

• Wataru Katou as Rentaro Aijo

• Kaede Hondo as Hakari Hanazono

• Miyu Tomita as Karane Inda

• Mary Country as Shizuka Yoshimoto

• Asami Seto as Nano Here

• Ayaka Asai as Kusuri Yakuzen

• Sumire Uesaka as Hahari Hanazono

The New Additions (The Next Wave)

Because the series relies entirely on the introduction of fresh, wildly eccentric soulmates, Season 3 will formally introduce a controversial and highly anticipated manga character: Chiyo IruniRentaro’s strictly disciplined, rule-abiding younger cousin, who becomes the next addition to the growing group.

Plot Details: What to Expect in Season 3

The narrative engine for Season 3 kicks off with a massive meta-joke setup. At the end of Season 2, the anime reached 11 total girlfriends, which means Rentaro is officially entering the next tier of his monumental task to juggle 100 soulmates without letting a single one experience a fatal heartbreak.

The plot of Season 3 opens with Episode 1, adapting the “Cousin’s Girlfriend” storyline from the manga. The upcoming episodes will heavily balance the growing pains of managing an enormous collective date cycle with pure, unadulterated gag-comedy. Expect intense segments detailing a highly anticipated “Kissing Ban” training arc, chaotic group dates designed to test Rentaro’s absolute limits of multi-tasking devotion, and the series’ signature reality-bending fourth-wall breaks where the characters actively argue about their own manga chapter placement and anime screentime limits.
