Yuuji invades Oslo's ship alone and takes out several of the latter's men. Meanwhile, Agnes and JB inform Yumiko that they are currently 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 Yuuji after learning everything about him. On the deck of Oslo's ship, Yuuji meets a man who looks just like him but with white hair. The look-alike, who calls himself Du Pont, also refers to himself and Yuuji and Kazuki's brother. The two engage in an intense and fast paced fight to the death. Yuuji appears to have the advantage at first until Du Pont injects himself with a booster drug and tries to make Yuuji do the same but he refuses. With the drug boosting his physical abilities, Du Pont gains the advantage which forces Yuuji to take the drug as well. The two fight evenly but Yuuji ultimately wins and kills Du Pont.
