The manga series Kaiju No.8 has come to an end in Shonen Jump+ after a 5 year run starting in July of 2020. Winner of a number of Manga awards in 2021 and 2022, the series received positive critical reception and even has a highly rated anime adaptation still airing.
English fans of the series will have to wait a while to able to complete their physical Kaiju No.8 Manga collection though the series can be read up to the final chapter over at Viz media's Shonen Jump platform. For those collecting Japanese manga releases, the final 16th volume will be hitting store shelves in September.
