I have a cushion I don't use anymore, so I was thinking about throwing it away. But I leaned against it when I went to toss it out and remembered how comfortable it was, so now I can't throw it away.

Sometimes I livestream myself drawing. Solitude used to be one of the perks of working late at night, but now I enjoy a raucous time with people from around the work while I work. It's amazing the way times change!


  • Many parts of the cover and inner cover pages of volume 11 and 13 are ideas and thoughts from the translator and stream audience. If you are able to speak Japanese, feel free to suggest something when Murata is asking for ideas during his stream!
