The God of High School opens with a claim and a promise. Jin Mori, a 17-year-old martial artist from Seoul, says he is the strongest high schooler alive. Then a shady corporation invites him to a tournament that will test it, and tells him the winner gets any wish granted, no question asked.
That is the engine of the 13-episode anime television series adaptation produced by MAPPA, which aired on AT-X from July 6 to September 28, 2020. The show is based on Yongje Park’s South Korean manhwa, serialized on Naver Webtoon from April 2011 to December 2022 and translated into English by Line Webtoon starting in July 2014.

Jin Mori and the Wish
Mori fights with Renewal Taekwondo, a fictional version of the Korean martial art, later shortened to Re-Taekwondo. He is carefree, friendly and self-proclaimed as a “Tough guy.” His reason for entering is simple: he wants strong opponents, and he wants to be reunited with his grandfather Taejin.
The tournament runs regional, then national, to pick three representatives for a World Tournament. The prize is the wish. That structure gives the series its early momentum, and it gives Mori a motive that is personal rather than abstract.
Two Prodigies and a Team
During the opening rounds Mori meets Daewi Han, a Full-Contact Karate expert, and Mira Yoo, an epeeist master. Both fight him, both befriend him, and the three become the Korean Team after the preliminaries.
Daewi’s stake is the heaviest. He is a hard-working 17-year-old paying off his best friend’s hospital bill for terminal cancer, and he enters the tournament to cure the disease. When his friend dies, he finds a new purpose through Mori and Mira, wanting to help them fulfill their own wishes.
That turn is the series’ best material. It takes a standard tournament premise and gives one of its three leads a reason to keep fighting after his reason is gone.
Borrowed Power and Three Realms
The fights are not only fists. Participants use “Borrowed Power,” or Charyeok, a mystical energy granted by supernatural entities. At the dawn of time humans, demons and gods lived together on Earth. The gods let weak humans borrow their powers to defend against demons who wanted to rule them. After the demons were defeated, the gods split the three groups among three realms: the Human Realm, the Sage Realm and the Heavenly Realm, in ascending order of power.
Humans can still use Borrowed Power freely, but they are not allowed to attack gods with it. The Sage Realm holds dragons, minotaurs and phoenixes. The Heavenly Realm holds gods from many mythologies, including the Jade Emperor, Michael the Archangel and Hercules.
Mori is labeled a Genuine Fighter, meaning he relies on martial arts rather than borrowing power. The source of his strength is stranger: his true identity is the mythical Jaechondaesong, or Sun Wukong, the hero of the Chinese novel Journey to the West. After RagnarÖk, he takes a new form and name, Dan Mori, after Park Mujin kills his grandfather and seals his powers.
A Cast That Carries the Chaos
The Japanese voice cast is Tatsumaru Tachibana as Jin Mori, Ayaka Ohashi as Yoo Mira, Kentaro Kumagai as Han Daewi and Koki Uchiyama as Park Ilpyo. The Korean cast includes Nam Doh-Hyeong and Kim Bo-Na as young Mori, with Robbie Daymond voicing him in English.
The series carries four genre tags: Animation, Comedy, Action & Adventure, and Sci-Fi & Fantasy. It earns the last one. The realm system and the Borrowed Power mechanic are what separate The God of High School from a crowded field of tournament anime.
What Holds and What Slips
The premise is chaotic by design, and the show leans into it. A battle between unbelievably strong high school students is the pitch, and the series delivers on that pitch without apology.
What matters most is the three-person core. Mori’s wish, Daewi’s grief and Mira’s ambition give the tournament stakes that a pure fight card would lack. The realm mythology is the show’s second-best asset, and it arrives late enough to feel like an escalation rather than a premise dump.
The weakness is the same one that dogs most adaptations of long-running webtoons. Thirteen episodes is a narrow window for a story that ran more than a decade in print, and the series has to move fast through material that rewards patience. The shady corporation behind the tournament stays vague for long stretches. Viewers who want the conspiracy explained early will wait.
But the show’s confidence is real, and it is earned by its fights and by Daewi’s arc in particular. This is a tournament anime that remembers the people in the bracket.
