Synopsis

The protagonist, Logan, visits the Duke, who he suspects was the sword master he encountered earlier. Logan presents the Duke with a powerful aphrodisiac, a highly concentrated version of an earlier product, knowing it could have a significant effect on an aura user. Impressed by the gift and its potential, the Duke offers to repay Logan's kindness, and instead of taking the offered favors, Logan asks for a swordsmanship book. Ultimately, the Duke decides to personally teach Logan a sword technique.
