⚔️ Main Concept
A century after the fall of the last shinobi nations, chakra has been forgotten.The world is ruled by Eclipsed Lords — godlike beings born from corrupted emotions of ancient shinobi.The immortal shinobi Ren Uzuhara, once the last protector of Konoha, awakens from self-imposed stasis to a world where emotion is outlawed and pleasure is considered sin.
His soul is fractured between guilt and desire — and when he meets Sakura Rei, a descendant of an extinct bloodline who can awaken memories through touch, their connection begins to shatter the new order.

💞 Emotional + Sensual Tone Guide
To keep the romance dark yet tasteful, use:
Emotional intimacy before physical. (The desire must come from shared pain.)
Symbolic sensuality. (Touch = memory / pleasure = awakening.)
Contrast tenderness and tragedy. (Loving scenes lead to emotional consequences.)
Sensual but poetic phrasing. (Focus on heat, breath, closeness — not explicit anatomy.)
