Reika Shimohira is a young, beautiful and popular idol who dies during Izumi’s killing spree in Shinjuku. Pulled into the Gantz game, Reika proves to be a formidable opponent against the aliens and also happens to fall in love with Kei Kurono.
She takes over the team leadership when he eventually departs, but a rebuff to her advances leads to a small mental breakdown and she realigns her goals in order to make the required 100 points in order to revive a new copy of Kurono for herself!
Reika is stunningly brought to life here by popular cosplay and gamer girl Linda Le, probably best known by her online handle, Vampy!
