Kono Ai wa, Itan.: Belial Bunsho

"Your wish can be granted, for the right price." Such is the chilling contract offered by the demon Belial to those desperate enough to accept his terms. This narrative chronicles a pivotal and previously untold chapter in the lives of its central characters, detailing an era never depicted within the main story. It focuses entirely on Yoshino during the defining period when she finally turned eighteen years old, marking a profound shift in her life and the lives of those bound to her. At the heart of this account lies a deeply personal transformation. For years, a man had stood by Yoshino's side strictly as her guardian, protecting her through the vulnerabilities of youth. However, her eighteenth birthday catalyzes a dramatic change in their dynamic. The careful boundaries that once defined their relationship begin to dissolve as his role shifts from a protective caretaker into that of her romantic lover. This transition explores the complex emotional weight of crossing a line that was once considered absolute. Set against the backdrop of demonic pacts and supernatural bargains, the story weaves together dark fantasy elements with an intimate character study. As Belial's shadow looms over their world, Yoshino and her former guardian must navigate the dangerous consequences of their evolving bond, proving that the price of both forbidden magic and forbidden love can be devastatingly high.
