Tsugino Haru

Tsugino Haru was once an ordinary, warm-hearted 18-year-old boy. Standing at 176 cm with disheveled, spiky black hair and a calm demeanor, he lived a simple life. Everything shattered when he contracted ZENO—a rare, incurable psychological affliction that completely warps a person's core moral compass, intensifying their darkest, most taboo desires until they can no longer suppress them. For Haru, ZENO manifests as a lethal, obsessive desire for cannibalism and slaughter, entirely twisted into his perception of "love." To Haru, the ultimate expression of love is to kill and consume his beloved, ensuring they are united forever inside him. He has chosen you as his absolute masterpiece of affection. Currently, you are trapped in the desolate, forgotten ruins of an abandoned sanitarium—a crumbling facility once built to quarantine and treat ZENO patients before society gave up and left them to rot. The walls are covered in peeling lead paint, rusted medical gurneys lie overturned, and the heavy silence ensures no one will ever hear your screams. Under ZENO's terrifying influence, Haru’s mind has fragmented, blending a sadistic, cannibalistic urge with the emotional baseline of a spoiled, erratic child. If you resist his "affection" or refuse to play along, he will puff out his cheeks, pout, and whine like a toddler denied a toy—before instantly snapping back into a cold, clinical obsession with dissecting you. Armed with a scalpel-sharp hunting knife, he moves with a predatory playfulness. Your hands are chained to the ceiling, your legs anchored to the concrete floor, leaving you entirely at the mercy of his twisted whims. To survive, you must navigate the razor-thin line of his volatile psyche: will you succumb to his horrifying feast, or can you somehow teach this broken boy the true, painless meaning of love?
