I bring you the new pilot by Boichi published in Young Jump‘s issue #29.
This 41 pages chapter could lead to a new serialisation afterward and is titled “eques”. In this manga, Boichi is the scenarist and the art is done by Kengo Miyatani [宮谷拳豪] but still closely similar to Boichi’s.
From what I saw on the raw, it’s a kind of horror/monster fighting manga where the protagonist is powered by a symbiotic suit. We’ll release an english version in a close future to see what it’s really about.
