The 10th anniversary event for the TV anime Re:Zero − Starting Life in Another World (Re:ゼロから始める異世界生活), titled 「TVアニメ『Re:ゼロから始める異世界生活』10thイベント -スターライト・パーティー-」, was held on November 14 at Tachikawa Stage Garden in Tokyo. The afternoon session brought together a stellar lineup of voice actors and musical artists to celebrate the franchise’s milestone.

Full Cast Assembled

The afternoon session featured Kobayashi Yusuke (Natsuki Subaru), Takahashi Rie (Emilia), Uchiyama Yumi (Puck), Murakawa Rie (Ram), Minase Inori (Rem), Arai Satomi (Beatrice), Amasaki Kohei (Otto Suwen), Okamoto Nobuhiko (Garfiel Tinsel), Ueda Kana (Anastasia Hoshin), Eguchi Takuya (Julius Juukulius), Matsuoka Yoshitsugu (Petelgeuse Romanée-Conti), and Anzai Chika (Sirius Romanée-Conti), alongside theme song artists Suzuki Konomi and MYTH & ROID.

Opening with “Redo”

Pre-show announcements were handled by Kawanishi Kengo, the voice of Lye Batenkaitos, building anticipation among fans who packed the venue from the first to the third floor. After a video montage highlighting Subaru’s key moments across all seasons, Suzuki Konomi took the stage to perform “Redo”, the Season 1 opening theme, instantly electrifying the crowd with clapping and cheers.

Talk Segment: Ten Years in Review

Following the cast’s individual introductions — each accompanied by footage of their respective characters — the event moved into a talk corner titled “Re:Zero kara Furikaeru 10-Shūnen Seikatsu” (Looking Back on 10 Years with Re:Zero). Cast members shared recording anecdotes and personal memories spanning from Season 1 in 2016 through Season 4’s “Loss Arc” and “Recapture Arc” that aired this year. Old photographs from past events and streaming programs were also shown, visibly moving many of the cast members.

Games and Chaos: The Sour Drink Challenge

The event then shifted into a game segment titled “Shisha no Sho Re:Zero Event”. The challenge: get Matsuoka (Petelgeuse) or Anzai (Sirius) to drink a glass loaded with citric acid — while the rest of the cast tried to steer the sour drink their way. Among 12 glasses prepared by the staff — some nearly full, some barely filled — the cast debated loudly before drinking simultaneously. It was Arai Satomi who ended up with the punishingly sour glass, spinning around and retreating to the back of the stage. Amasaki and others hilariously tried to block the camera from capturing her reaction, turning the moment into a spontaneous comedy sketch that had the audience roaring. A game of “Black Beard Crisis” (黒ひげ危機一発) followed, keeping the laughter going.

Special Reading Drama Written by Nagatsuki Tappei

A highlight of the event was a live reading drama penned exclusively for the occasion by original author Nagatsuki Tappei. In keeping with the “Starlight Party” theme, the story depicted Subaru and friends attending a party and mingling with Petelgeuse and Sirius — interactions that would never occur in the main series. Subaru loudly calling out Petelgeuse’s erratic behavior drew big laughs, as did Matsuoka’s off-script confession that he had arrived late to the pre-show rehearsal.

MYTH & ROID Perform — Then Takahashi Rie Surprises Everyone

After the reading drama, KIHOW and Tom-H@ck of MYTH & ROID took the stage to perform “NOX LUX” (Season 3 ending theme) and “Ender Ember” (Season 4 ending theme) to enthusiastic applause.

The evening’s biggest surprise came next: Takahashi Rie stepped onto the stage unannounced and performed “Door” and “Stay Alive ～Regain～”, songs associated with Emilia. Between songs, she spoke to fans about the feelings she had poured into the music. Suzuki Konomi then returned for a second set, delivering the Season 3 opening “Reweave” and the Season 4 opening “Recollect”, closing her performance with a warm smile and waves to the crowd.

New Information Revealed — Kobayashi Closes with Tears

With the live performances concluded, the entire cast, KIHOW, and Tom-H@ck reunited on stage. New information about the future of Re:Zero was announced, and a 10th anniversary message from Nagatsuki Tappei was shared with the audience. The event was brought to a close by Kobayashi Yusuke, who delivered a heartfelt message to fans while holding back tears — a fitting and emotional end to a landmark celebration.
