@nanze It's not the author (Chica Umino) that had the depression but the shogi player Senzaki Manabu.
The Wikipedia also says: "The manga has commentary by professional shogi player Manabu Senzaki on shogi rules and culture."
I just assumed you were talking about Chica Umino because you used...
@Epicredeemer maybe because it is from the same mangaka? At least she posts new parts in her twitter: https://twitter.com/zyugoya/status/1075689579020046336 .
Edit: Maybe the author's name should be changed so they match in both manga?
@Wancakes @sadmanex I would assume it's the cover for the 3rd Light Novel volume? If I'm wrong, someone correct me.
@gaigous yes that isekai is the one you are reading right now. Mizuryu Kei draws the illustrations for the LN.
@Mogima False alarm for you.
