Saw this funny isekai sequence, where the MC was badmouthing Douluo at an anime convention, and then a deranged Tang San cosplayer ran up to him and threw blue silly string at him screaming blue silver entanglement and then knocked him down and then started hammering his face with an actual hammer, and then the MC reborn in Douluo with his infinity gauntlet (toy), rinnegan (contact lens), sukuna (doll) jinchuriki
