Kuzureru Tenbin

When Euris comes to his senses, he finds himself strapped to a table, bound by tough belts, a straitjacket, and a muzzle. Where is he? Who is this evil man in the lab coat? How does he know Euris's name... and how to make him moan and whimper? Something is off and it's not just Euris's pants. Will he regain his memory before it's too late? Will Euris accept his new truth and reality?
