user 166417 about 4 years ago I was thinking that this artist might be tenako_(mugu77).There are just so many similarities between them.
SciFi about 4 years ago Might be actually, both of tenako's pixiv accounts are gone. inupora appears a couple months after tenako's last know post. Unfortunately there's no links or anything to verify, though after two accounts being lost you couldn't really blame them.
