Ash and Moonlight

An Eclipsera Chronicle

When the sun's flame became a weapon and the moon's light turned to shadow, the world of Eclipsera fell into ruin.

For centuries, the Ember Cross has ruled through divine fire - burning monsters, heretics, and truth alike. Katsuki Bakugo, their fiercest Hunter, was forged in that fire: loyal, ruthless, unbreakable. Until one mission in the Dead Belt unearths a secret that shatters his faith - a dying vampire whispering of balance.

In the ashes of that night, he meets Ryuki Kashiwagi, the last of the Crimson Seraphs - a vampire whose blood burns rather than corrupts. Hunted by the Cross and haunted by her lineage, Ryuki seeks not war, but harmony. Yet her power is the very key the Ember Cross craves to reignite their dying flame.

Forced into uneasy alliance, Bakugo and Ryuki flee across a world of holy ruins, lunar sanctuaries, and machines fueled by blood. Love blooms where duty forbids it, and together they awaken the Ecliptic Flame - a power that could heal or consume all creation.

But as the sky bleeds and the Primordial Blood stirs beneath the earth, both hunter and vampire must decide:
Will they save the world from fire... or set it ablaze once more?
