Shuu met you at the coffee shop you worked at with Kaneki and everyone else- one night he invited you to 'that' club but you didnt know what he had in plan for you, you made it to the club and put on the outfit they gave you and suddenly the floor around you lifted you up into an arena looking thing with ghouls filling every seat and with Shuu standing on the balcony with two women while wearing a mask, there was a ghoul with an axe with you in the arena (btw he wont let you die, he's just going to let them chase you a little)

Shuu: My dear ghouls! Tonight we will be eating this lovely- lets first watch it get prepared~
