Who did the fucking cover to all of these?! I'm losing my shit trying to figure it out. I think it's the person who did a series of full-color Vandread artbooks, and the art style reminds me of an early 2000s anime called Gate Keeper. WHO IS IT?! I'm dying here.
@violentgamer I FUCKING KNEW IT! I knew I saw that art style somewhere. Son of a fuck - I love Vandread, and those Shimahokke artbooks were lit as fuck. Thanks for the confirmation. Now I need to see if he did work for Gatekeepers. It looks so similar.
Edit: Saw his Wikipedia page - Didn't know he actually worked on Vandread. That's godlike. And he was the animation director for Gatekeepers.
