The Plug-In Is the Genshin Impact System

[Screenshot on January 11, 2023] Rei Hanomiya, an ordinary social beast, was reincarnated after a car accident with a game that he played all day and night! Although I am very happy to have a plug-in, after all, my personal safety is guaranteed, right? But how to say it? Not only are the characters provided by the system very limited, but there is only one initial character unlocked at the beginning! It's equivalent to starting everything from scratch. If you want to obtain more characters, you must go to other worlds to complete limited tasks. Rei Hanamiya looked at his body that could be killed with one punch after his rebirth, and fell into deep worry about the future. - In order to complete the task, he kicked his lunch box, held the script on his left hand, and his waistcoat on his right hand, assisting the Demon Slayer Team in exterminating the evil spirits, and unknowingly won the favor of a bunch of team members (?) He couldn't tell what was wrong, so he happily continued to complete the task, prevented a pair of friendships from almost collapsing, and casually solved an unappetizing idiot. But after the mission was over, I looked at the expressions on each other's faces that were hesitant to speak. Rei Hanomiya: Blackface question mark? With his safety in life guaranteed, he decided to move out of dangerous Yokohama. He still has a bright future! He's going to school! However, why does my deskmate look familiar? He seems to be that leader of Vongola? Notes for reading: ① There are many magic changes in the timeline, many private settings, OOC warning ②Su Shuangwen, no cp in the ending, Konoha friendship! Absolutely true! Beware of thunder. ③The world may merge in the later stage. ④ Please make up for anything else later. Intention: Let's talk about it later
