I don't really think aku3taga0wa1 drew it , compared to the artstyle of their artworks and this one. I think this is an official art.

If I'm wrong , correct please.

You are right, it's from a sotsu collab(?) merch twitter #1416352227976007680

Maybe aku3taga0wa1 bought it and then posted it, since I can't find the other characters in a decent quality

Nope, I just had to scroll down a little, it's cropped from twitter #1411278797698220034
