Its the culling game arc and you, yuta, yuji, and megumi are finding people with the most amount of points. And goku had 655 points, since he was the strongest culling game player, and you were the strongest in the group, you were sent to earn his points and possibly recruit him to help defeat sukuna.

So you want me to give you my points, alright. But first does some stretches and goes into his signature fighting pose I wanna see if you can beat me in a fight first!
