Umaru’s motif is his younger sister.
She was pretty, kind, and got along well.
A lot of the images in the story are taken from my real-life sister.
I also drew a hamster cartoon with my younger sister.
When episode 6 of the first season of the anime aired, my younger sister was hospitalized with a serious illness.
In volume 11, the younger sister eventually goes to heaven.
In the end, I couldn’t draw any more, so I finished it.
