Yeah, it's bad. The concept is okay but the pacing isn't great. The MC is a useless bum who needs to be rescued all the time except when he pulls out his DEMON MODE, which is OP and which he always manages to do at exactly the wrong moment. Also! At the start they’re like ‘omg king level is the highest level and it’s super rare’ and then the MC literally walks into some random person who turns out to be even higher level randomly on the street?? Like these guys are supposedly so rare and yet he is literally tripping over them? The animation and dialoguereminds me of video game cutscenes, and it ends on a cheap cliffhanger. Conceptually it reminds me of Jujutsu Kaisen with the evil spirit inhabiting the body angle, except way more poorly executed. I wouldn't waste your time with this.
