From the last message left by Ishinoo, Yashiro instinctively senses that there is something connected to the "Half-Dragon" behind Jogamine, Indou, and Sarah. When Jogamine and Indou come to BAR Goonies and beg Yashiro for new training, he comes up with a plan. Later, Yashiro, accompanied by his three disciples, infiltrates the party venue of Lord Storm Coffin, the Great Demon King said to be the strongest in western Tokyo.

Having been severely injured protecting Indou, Yashiro takes command of his disciples, instructing them to work together. By complementing each other's weaknesses and utilizing their unique strengths, the three steadily defeat the Nephilim. However, one Nephilim attacks the battered Yashiro. Ido and Levi, who control the Nephilim, also appear, and the hero's battle reaches its climax!
