1. Umaru itself is a character created based on the motif of his younger sister (he is friendly, pretty, good at studying, and even spreads around the house)
Although they were 2.2 years apart, their parents were busy from a young age, so they took care of them and raised them.
3. I drew cartoons as a hobby at school, and when I came home, I played with my younger sister drawing cartoons, and those were hamster cartoons.
4. (Umaru) Even when the series started, my younger sister was happy and said, “It’s my story haha.”
5. The problem is that when episodes 6-7 of the first season aired, my younger sister became seriously ill and began to be hospitalized.
6. I was contacted via messenger saying that it was a serious illness and that there might be a big problem, but the writer himself took it lightly, saying, “It’ll be okay, so don’t make a fuss~”
7. Umaru left for heaven around volume 11. At that time, I was so sad that I went into a slump thinking, “Why am I drawing this?”
8. Even though I understood it in advance, I couldn’t help but think, “Why my sister?”
9. The cover of Umaru’s volume 11 shows Umaru wearing a shirt, modeled after the shirt in his sister’s photo (I wanted to keep it as a memory)
