The main character of a doujinshi titled Chokujou Shinki | 直情真気 created by Drum-kan (Kine). It was later animated by Danzi Engine (aka Shiba Yuuji | 司馬ゆうじ). The Lora was trained on the animation.
Base model used: Illustrious v2.0
There is no mention of his name anywhere so I used the name of the doujinshi title as the trigger word :D
