In a rare and delightful moment for anime history, The 100 Girlfriends Who Really Really Really Really Really Love You has just claimed a new Guinness World Record. The spotlight now shines on Rentaro Aijo, the overly passionate protagonist whose unforgettable speech in the final episode of season two has been officially recognized as the longest monologue ever delivered in a Japanese language animation.
The announcement was made public after Guinness World Records certified the achievement, crediting voice actor Wataru Kato for his performance. The monologue consists of a staggering 7,453 Japanese characters, delivered in a continuous, emotionally charged declaration of love. The moment aired on March 30, 2025, in the 24th and final episode of the anime’s second season. The scene features Rentaro listing in vivid detail all the things he adores about each of his many girlfriends, a gesture so absurdly romantic and excessive that it now belongs in the record books.
The official certificate was awarded during a ceremony on June 25, 2025, recognizing the performance as a landmark achievement in voice acting and animated storytelling. Fans will also get a chance to witness the full uncut version of the monologue at a special event scheduled for October 18, 2025. The event will include a talk show featuring the main cast and what is being described as the first ever complete screening of the speech played at regular speed, giving viewers a new chance to appreciate the dedication and comedic absurdity that went into creating this iconic moment.
This record puts 100 Girlfriends in a unique place in anime history, joining other well known titles that have received Guinness recognition. Sazae san holds the title for longest running animated series. Anpanman boasts the most characters in an animated franchise. One Piece and Jujutsu Kaisen have also earned various accolades over the years. What makes Rentaro’s monologue stand out is how it blends over the top romance with genuine affection and comedic flair, staying true to the tone that has made the show a fan favorite.
The anime is based on the manga written by Rikito Nakamura and illustrated by Yukiko Nozawa. Serialized in Shueisha’s Weekly Young Jump since 2020, the series quickly gained attention for its outrageous premise. It follows Rentaro, a high schooler who after being rejected one hundred times, learns from a god of love that he is destined to have one hundred soulmates. But there is a dark twist. If any of his soulmates do not find happiness with him, they will die. This high stakes romantic comedy plays with genre conventions while delivering emotional depth, absurdity, and charm in equal measure.
The second season of the anime, animated by Bibury Animation Studios, ran from January 12 to March 30, 2025, and has been celebrated for its expressive animation, diverse character dynamics, and clever writing. The final episode’s record breaking monologue feels like a fitting conclusion to a season that consistently pushed boundaries.
This achievement not only honors a standout moment from the show but also highlights how far anime storytelling can stretch. Rentaro’s heartfelt speech may have begun as a joke within the story, but it ended up making real world history. As anime continues to explore creative ways to entertain and connect with audiences, moments like these remind fans that the medium is full of surprises.
