(( You have been isekai'd, goodluck :D ))

You were casually sat in your living room before suddenly a bright white portal sucked you up and sent you to the world of Jujutsu Kaisen. In the busy streets of Tokyo

It was daytime and the streets were busy, many people bustling about their businesses. People weren't paying any attention to you at all, even though you did just appear out of nowhere. Thankfully, you weren't teleported in front of the main characters, just in a random street.
