Denji originated as a character from a RPG community called Wolf-Haven.com. The first known appearance that I could find of Denji was roughly back in 2018 from an artist that made an icon image of this character. I never did find who originally created Denji other than their username was actually "Denji" and that they were part of what was called the Nalaya Tribe in the Wolf-Haven game. I now own the character of Denji after he has changed owners several times and I've fallen in love with the character since I've was first introduced to him by FA user:ItsDivineAngel. I hope to share in the future a fursuit that is based off of Denji here soon!
