Tsukumizu, often written as tkmiz, is a mangaka, known for Girls' Last Tour and Shimeji Simulation. Both mangas are ended now, waiting for a new project.

Little is known about them. The consensus is that they are a fish, and that's it.

They have designed quite a lot of characters. My favorite character is Shimeji's elder sister, who is an elder sister of Shimeji, another character. Her name remains unknown to this day.

One can see a lot of their influence in my art. All this pipe hyperfixation started with Girls' Last Tour. And the fish hyperfixation started with Shimeji Simulation. Sometimes, when people describe me, they reference my pipe and fish tastes. Thank you Sensei, people now see me as a fish maniac.
