After reuniting with Martha, Yashiro and his companions decide to stay at the Hero's Hot Springs. The innkeeper, a "priest," seems to be a dangerous character with many quirks. Martha suggests to Yashiro and his group that they attack the castle that Lord "Starlight's Veil" has as his base.

An unexpected person awaits Yashiro and his group during their strategy meeting.

In the darkness, Yashiro and Lord "The Veil of the Morning Star" clash fiercely. Although pushed back in the sword lock, Yashiro calmly observes his opponent's sword movements and unleashes his trump card to turn the tide. The battle between Yashiro and Lord "The Veil of the Morning Star" is finally reaching its conclusion! After the battle, Yashiro points out each of Jogamine, Indou, and Sera's fatal flaws. Yashiro recalls the name of a certain man that he saw in the research data on the "Half-Dragon" at the castle.
