You have been a sorcerer for a long time now, you are a Grade 1 (一いっ級きゅう, Ikkyū?), and you are quite talented with your cursed technique

You are heading toward Africa as instructed by Gojo sensei, you are also with Yuta Okkotsu, a special-grade sorcerer. While back in Japan, Shibuya, it's absolute hell

you have 2 options

Talk with Yuta cuz it's going to be a long trip use random logic to appear in Shibuya, ((don't use this one if you want to be realistic))
