The wait for more chaotic romance is almost over. The third season of The 100 Girlfriends Who Really, Really, Really, Really, REALLY Love You has released its first teaser trailer, giving fans a look at what is coming this summer. The new footage confirms a July 2026 premiere date and introduces the voices of two new girlfriends joining Rentaro’s ever-growing family.
The teaser video dropped on March 20, 2026, across official channels, sending excitement through the anime community. The 30-second clip shows the Rentaro Family working together toward a new goal—performing on an idol stage. The animation looks sharp, and the tone remains just as wild and funny as previous seasons.
New Trailer Reveals Idol Arc and Two New Voices
The newly released teaser trailer gives viewers a taste of what Season 3 has in store. The video shows Rentaro and his 13 girlfriends training hard for what appears to be an idol performance. The group is working toward their goal of getting on stage, adding a musical element to the already packed story.
A major highlight from the trailer is the debut of two new character voices. Fans can hear Chiyo Iin and Naddy for the first time in the teaser, though their voice actors have not been officially named yet. The voices match the characters’ personalities—Chiyo sounds responsible and proper, while Naddy speaks in her unique energetic style that mixes Japanese and English.
The trailer also includes a preview of the insert song “HAKOBUNE 100 nin no ttemo daijobu,” performed by the Rentaro Family cast. The upbeat track fits the idol theme and gives a hint of the musical episodes to come.
July 2026 Premiere Set for Third Season
The third season will begin airing in July 2026. The official announcement came alongside the teaser trailer, confirming the summer release window. Production is once again handled by Bibury Animation Studios, the same team behind the first two seasons.
Hikaru Sato returns as director, with Takashi Aoshima continuing as series composer. Akane Yano is back as character designer, ensuring the visual style stays consistent with what fans loved in earlier episodes. The returning staff means viewers can expect the same high-quality animation and sharp comedic timing.
Two New Girlfriends Join the Rentaro Family
Season 3 introduces two new characters to Rentaro’s growing circle of soulmates. Chiyo Iin is Rentaro’s cousin and a responsible middle school class representative. She brings a more serious and organized energy to the group, though her feelings for Rentaro create plenty of awkward family moments.
Naddy, whose full name is Naddy, works as a Japanese language teacher with a unique personality. She grew up in the United States and tries very hard to act like a traditional American, but her understanding of American culture is completely wrong in hilarious ways. She speaks in her own “Naddy language,” mixing Japanese with English words she learned from movies.
The teaser trailer gives fans the first listen to both characters, though the official voice actors will be revealed at AnimeJapan 2026. The event takes place at Tokyo Big Sight on March 28, 2026, where a talk show featuring Wataru Kato (Rentaro’s voice actor) will include the new cast members as secret guests. The stage event will also stream live on YouTube.
Returning Cast and Staff for Season 3
The main voice cast returns for the third season. Wataru Kato voices Rentaro Aijo, the boy destined to love 100 girlfriends. The returning heroines include Kaede Hondo as Hakari Hanazono, Miyu Tomita as Karane Inda, Maria Naganawa as Shizuka Yoshimoto, and Asami Seto as Nano Eiai. Other fan favorites like Kusuri Yakuzen, Hahari Hanazono, and Iku Suto are also back for more adventures.
The production team remains the same, with Bibury Animation Studios handling animation production. Takashi Aoshima continues as series composer, maintaining the show’s signature blend of rapid-fire jokes and genuine romantic moments. The costume design team now includes Riko Iwata alongside returning designers Mika Nishiyama and Tsumugi Maeda.
