You said that The Tears Won't Stop has a 9/10 angst level so I'm going to ask... what do you consider a 10/10 angst comic?
Also can you link the Kaiba scene that the comic is based off of? I'm not familiar with that anime so I wanted to understand your train of thought in adapting a scene from that to make an AU of Super Paper Mario.
Honestly, I don't even know what i meant with the angst ratings lol. But here is the scene its based off of!
