🧟‍♂️⚔️ Otherworldly Munchkin: Let’s Speedrun the Dungeon with Only 1 HP! (2025) — One Life. One Mission. No Room for Error.

"If I mess up once… It's game over."

Get ready to die trying—literally. Coming this October 2025, Otherworldly Munchkin: Let’s Speedrun the Dungeon with Only 1 HP! launches exclusively on Crunchyroll, and it’s not your average isekai anime. With a killer premise, high-speed action, and just 1 HP on the line, this wild dungeon-crawling adventure is a heart-pounding ride from start to finish.

Adapted from the manga by Yū Shimizu and Makoto Aogiri, and animated by Studio Durandal, this series promises tight pacing, unpredictable strategy, and emotional depth—all powered by sheer determination (and a serious lack of hit points).

💀🎮 The Plot: Reincarnated, Reckless, and on a Rescue Run

Yukito Kirihara, a 16-year-old boy living with his beloved younger sister Sana, doesn’t exactly expect an ogre to come crashing through his window. But when it targets Sana, Yukito throws himself in the line of danger—and pays the ultimate price.

That’s not the end, though.

A mysterious woman offers Yukito a second chance in a fantasy world, handing him a character sheet from a strange book. But the real twist? Sana is also inside that book. Now reborn in a magical land, Yukito must race through deadly dungeons, boss battles, and glitch-like traps to find her.

The problem? He only has 1 HP—no healing, no margin for error, and no time to lose.

"Speedrunning a dungeon with 1 HP isn’t just hard—it’s suicide… unless you play smarter than anyone else alive."

🧙‍♀️👑 Characters: Speedrunners, Sorceresses, and Siblings

• Yukito Kirihara (Voiced by: Kazuki Ura)A gaming-savvy teen reincarnated into a brutal world with just one health point. His sharp wit and devotion to Sana are all he’s got to survive.

• Charlotte R. Brownia (Kana Yūki), Lumilia Sherwood (Yui Ishikawa), Liverna Dark (Kaori Maeda)— three powerful women with magic, mystery, and their reasons for aiding or challenging Yukito.

• Nephilia Curse (Yoko Hikasa), Rocinante (Fukushi Ochiai), and Managarmr (Ayasa Itō) add layers of chaos, mentorship, and menace.

📖📈 Origins: Dungeon Crawling with a Manga Mindset

Serialized since 2019 under Kodansha’s Suiyōbi no Sirius imprint, the Otherworldly Munchkin manga has carved a niche with its combination of speedrun gaming logic, dark fantasy, and emotional core. With 12 volumes and counting, it blends frantic combat with brother-sister loyalty and a sharp satire of game mechanics.

"You don’t need HP if you never get hit."
