8 parts Ongoing MatureKaito Renji, an 18-year-old Slayer wielding the silent precision of Void Breathing, lives by oath and discipline. His golden eyes betray nothing except when they linger on the wrong person. Beneath his stoic mask lies a heart willing to break every rule for someone he should despise.
Akihiro, a century-old demon cursed with Shadow Dominion, is feared for his hunger and cruelty. Yet behind the fractured gaze and sharp tongue is a soul chained by sorrow, tethered only by his dangerous attachment to Kaito. His love is both salvation and downfall.
What begins as a violent clash becomes an uneasy alliance, then a dangerous intimacy. Fighting beside Tanjiro and his friends, they earn suspicion and silence in equal measure. The Hashira argue: betrayal, some say, something deeper, others whisper.
But love here is no blessing. It is a curse. Through fire, shadow, and blood, their devotion grows even as it damns them. Kaito risks his oath; Akihiro risks his restraint. Together, they gamble with annihilation.
When Muzan sends his strongest demon to tear them apart, tragedy strikes. Kaito falls, but Akihiro's desperate love refuses to let him go. In defiance, he resurrects Kaito with his blood, not as hunger, but as a sin of devotion. Kaito awakens transformed: a demon of the abyss.
No longer Slayer or Demon, they vanish from both Corps and Muzan's ranks, carving a path belonging only to themselves. Bound in defiance, they become shadows haunting the war, a pair of lovers who should never have existed.
Eclipse of Desire is a tale of forbidden love, sacrifice, and tragedy, where devotion transcends humanity yet becomes the reason it is lost. Was their love salvation or the greatest sin?
