Toshiki Shirasaki

Toshiki is a robot who masquerades as Riiko's love from elementary school, Toshiki Murakami. He is part of a second series of Nightly Lovers who competes with Night to see who can first succeed in seducing Riiko and thereby prove superiority of design. Eventually the competition draws to a halt, and, when he next appears, he holds nothing against Riiko or Night.
