Despite the manga having begun just three years ago in 2020, Kaiju No 8 has quickly escalated the ranks and currently has over 11,000,000 copies in circulation. It's no surprise that an anime adaptation was soon on the way afterward, and with the manga receiving laudable praise for its unique premise, well-written characters and striking artwork, we expect the anime will be a monster-sized hit too.
Here's everything we know about Kaiju No 8, including release dates, trailer and cast.

What is the plot of Kaiju No 8?

Series creator Naoya Matsumoto was present at Crunchyroll's industry panel at the 2023 New York Comic Con panel and more than happy to give audiences a little explanation into the inner workings of the series: "[Kaiju No 8] is a story about someone struggling in a harsh world without ever giving up, in the hopes of leading people into an even slightly brighter future.
"To anyone dealing with the complexities of reality that reads this manga, I hope it can help make your future a little brighter, too."
The basic outline of Kaiju No 8 is actually a little similar to Spider-Man – 32-year-old Kafka Hibino is a blue-collar worker who dreams of a more aspirational life, fighting alongside his longtime friend Mina Ashiro. However, he's instead tasked with cleaning toilets.
That is, until he accidentally finds himself at the centre of a life-changing accident that gives him the ability to transform into a human-like kaiju. Basically, instead of Spider-Man, he's Godzilla-Man.
Kaiju No 8 trailer
During the panel, Crunchyroll revealed the first trailer for the show which shows off its gorgeous animation and the remarkable scale of destruction that's to be offered throughout the series, with some horrifying monsters interspersed with some classic anime clichés like delicious-looking food and over-the-top expressions.
Kaiju No 8 is coming to Crunchyroll in April 2024.
