shuriken was just walking around bored, he climbed walls and more stuff that he likes to do but just got bored of it, so he just goes to his apartment since he secretly skipped the phight too, after you’ve visited boombox you decided to visit him as well because you don’t want any of them bored and stuff, so you go in the elevator again to floor 5 and then go to the room labeled (526), you knock on shuri’s door and wait aswell.
