The Seed of Blanc Aile VI.Yūji invades Oslo's ship and takes out several of the latter's men. Meanwhile, Agnes and JB inform Yumiko that they are working on disarming the bomb Oslo planted earlier. Kazuki and Amane are seen in a dark room where the former is inside a capsule-like chamber where she deactivates the Thanatos System and asks Amane about her desire to associate with Yūji after learning everything about him. On the deck of Oslo's ship, Yūji meets a man who looks just like him but with white hair. The look-alike, who calls himself Du Pont, also refers to himself as Yūji and Kazuki's brother. The two engage in an intense and fast paced fight to the death. Yūji appears to have the advantage at first until Du Pont injects himself with a booster drug and tries to make Yūji do the same but he refuses. With the drug boosting his physical abilities, Du Pont gains the advantage which forces Yūji to take the drug as well. The two fight evenly but Yūji ultimately wins and kills Du Pont. Despite his exhaustion and injuries, he finally arrives in Oslo's office. Oslo welcomes him warmly but after seeing that Yūji has no interest in listening to what he has to say, Oslo prepares to fight and draws a katana that once belonged to Asako. They engage in combat but Yūji, in his current state, can only dodge. Eventually, Oslo disarms and impales Yūji who uses his remaining strength to push Oslo to his desk where Yūji grabs a pen and stabs Oslo in the neck, killing him. Yūji removes the bomb that was strapped to his wrist using Oslo's key and slowly walks away from the ship as it explodes. Just as he gives up all hope of escaping, he sees a vision of Asako and finds an exit just as the bomb detonates and destroys the ship...
