Yeah I think Redline exists just for the animators to brag about their skills. It's beautifully animated and a simple story.
If you want something similar, check out Promare.
And it was a comic, Books of Doom. Been a while since I read any manga, I wanted to get back into it recently.
Ohh.. I've heard of Promare, but never checked it out. Will do so! :)
Ohh~ I haven't really checked comic books... usually just manga or webtoon. :)
