Jump Comics is basically a significant platform in the manga industry. It releases a bunch of manga that attract readers of all ages and interests. Some of its famous series have become global sensations.
Well, it involves a team of creators including writers, illustrators, and editors. The writers come up with the story ideas, the illustrators draw the characters and scenes, and the editors make sure everything fits together and is appealing to the readers.
