If your Netflix queue needs a fresh weekly obsession this July, Thunder 3 (サンダー3) might be exactly that. The isekai mystery series — based on Yuki Ikeda’s manga from Monthly Shōnen Magazine — debuts globally on Netflix on 8 July 2026, with Singapore subscribers able to stream from day one.
What Is Thunder 3? The Manga That Just Ended
Thunder 3 ran in Kodansha’s Monthly Shōnen Magazine from May 2022 to June 2026, wrapping up its complete 8-volume run literally weeks before the anime adaptation premieres. Written and illustrated by Yuki Ikeda, the series sits at the intersection of isekai, mystery, and science fantasy — a more interesting combination than it might first sound.
The story follows three inseparable middle schoolers — Pyontaro Tezuka, Hiroshi Ochanomizu, and Tsubame Azuma, nicknamed the “Small Three” — who stumble upon a mysterious disc belonging to their teacher, Dr. Doc. Playing it unleashes an alien dragonfly from their TV screen, and in the chaos Pyontaro’s younger sister Futaba and the family pet are dragged into a parallel world and captured by its extraterrestrial inhabitants. What starts as ordinary boyhood friendship turns into an interdimensional rescue mission.
Netflix, Fuji TV, and a Surprising Director
The TV anime premieres on Fuji TV’s +Ultra block from 8 July 2026, broadcasting every Wednesday night, with Netflix handling global streaming from the same date. Singapore viewers can jump straight in on launch day — no region restrictions.
The creative team is worth noting. Per the Anime Expo 2026 press release coverage, Hiroyuki Seshita directs — the same filmmaker behind the bleak, atmospheric sci-fi of Blame! (2017) and Ajin: Demi-Human on Netflix. Series composition is handled by Hiroshi Seko (Witch Hat Atelier, Rooster Fighter), with studio UNEDN producing the animation. That pairing of a hard-sci-fi director with a chibi-inflected adventure story is one of the more unexpected creative decisions of the summer anime season.
North American Premiere at Anime Expo 2026
Thunder 3 gets its North American premiere at Anime Expo 2026 on 4 July — Room 408AB at the Los Angeles Convention Center, 3:15 PM PDT — with Seshita and Seko present for the panel. For Singapore fans weighing up a new seasonal watch, that screening lands just four days before the Netflix global drop, so any buzz coming out of LA will be very fresh when the series goes live on 8 July.
How to Watch Thunder 3 in Singapore
Thunder 3 is a Netflix exclusive in Singapore from 8 July 2026, with new episodes dropping weekly. The manga source is fully concluded at 8 volumes — available digitally through Kodansha USA’s Azuki platform for anyone who wants to read ahead or revisit the story after the credits roll.
