Well, the title page does say "Toho-Project & OnePunch-Man Fan Book". LOL (The letters are above Marisa's head, but they're a bit hard to see because of the bright background.)
Imizu mentioned on Pixiv that he wanted to recreate the battle scene from OnePunch-Man (He also mentioned the collaboration again on page 45). He sure picked the right characters to play the roles!

I always wonder when Imizu will make his own original manga, or what is he doing as current work. I heard he learned drawing in school, so I guess he does something in that way as actual job.
