Yakumo is youkai man who took on youkai children without relatives and lived with them in the deeply snowy mountains. He didn’t go berserk, and although he’s a huge-bodied, masculine man, he’s gentle and mature. He took down every child who went berserk, and built their graves one by one. He dreamed of a small, modest happiness, but that dream was cut down unfeelingly by the villagers below.
