Isn't this from a specific children's book? Where they painted stuff and it came to life? Might just be a coincidence that there's a tiger and the rough art style is slightly similar...

Reminds me of Ikkyu-san.

The pixiv comment points out that this was posted on the anniversary of Ikkyu-san's death.

I think next is Nazrin. I think it is still too soon for Byakuren and besides, I had always loved the interpretation of Kogasa as Byakuren's old umbrela so I would be happy if they get paired and then Kogasa can connect to TD casts.
Nevertheless, anyway is fine as long as we get more of his art.

Ah, the oldest cartoon gag in the book. Love it.

I;m thinking about Shinchan.
