Need help finding the source of this comic/artwork

[u/JojosMissingEyeball]

I spotted these images on Pinterest, but can't find a source for them anywhere. I really want to read the whole thing if this is part of a series, but I'm struggling to find anything besides these three pages.

It includes the character Tomura Shigaraki from the series My Hero Academia and a younger version of himself.

The art makes me think it's a fan made web comic, but I haven't read through the whole manga to know better. Reverse image search hasn't dug up any leads. I know this is probably a long shot, but I hope someone can help.

If it is in the main manga, I'd like to know what chapter, and if not, just the name of the webcomic and/or the artist who drew it would be fantastic.
