My Lord's Bedchamber Discipline

Set in the Warring States period, young lord Yoshimasa Tozenji rises through his military accomplishments. A rival lord, Uchizoe Joan, targets his life and dispatches a woman assassin. She infiltrates his chambers, but is discovered and captured. Struck by her beauty, Yoshimasa imposes his own form of punishment—yet her assassination attempt is far from over. In the darkness of the chamber, a tense struggle between the two begins.
