Artist. Releases works under the circle name "Tsumi-chan Honpo". Gives reading of name as "ツミタニ ダイスケ".
The third kanji in their name is actually the character for "shinu/shi" and is associated with death. Using the related meaning of "die", this is presumably where they come up with the reading of "dai" from.
Japanese name: 罪谷死輔
