Biryuu Enshoutan: Jiko Kouteikan ga Gekitei na Dragon-kyuu Bishoujo Maou wo, Yuusha ga IchaLove de Taiji suru Ohanashi

Iver, a dragon demon lord of immense power, has long since ceased to care. After countless cycles of resurrection and defeat at the hands of legendary heroes, the fire of her ambition has dimmed to a dull, cynical ember. Each new life has only brought more of the same—a relentless cycle of violence and loss that has left her with a profound lack of self-worth and a deep exhaustion with the world. Enter Mirio, the hero of the present age. By sheer accident, he stumbles upon the legendary holy sword, a weapon destined to slay the demon lord. But when he finds the apathetic and beautiful Iver, he does not see a monster to be vanquished. Instead, he sees the wounded soul beneath the dragon's wings. Unprecedented for a hero, Mirio falls head over heels for the very being he is supposed to destroy. This is the story of an unlikely couple: a demon queen with no self-esteem and a lovestruck, slightly dopey hero. Their bond is forged not in the heat of battle, but through hesitant steps of understanding and unexpected moments of tenderness. As they navigate a world that demands they be enemies, their fight is no longer against each other, but for the happiness they both thought was impossible. Can a hero's unwavering love ever heal a demon lord's ancient scars?
