This was one art collab that Yamada wasn't expecting to end so strangely.

I wanted to doodle some quick tickles but at the same time go for something a little more innocent and silly. I'm shocked I never thought of this idea before, I mean- it makes sense. Yamada is an artist so what would be more suitable than using familiar tools of his craft against him?

...I'm kinda curious to try this in person one day.
