Ep. 6: Gai dan Shu menyusup ke Bendungan Tsukigase untuk menonaktifkan sistem kendali Leukocyte sambil menghadapi Mayor Segai.

Gai survives the attack but reveals that his team and the mercenaries were killed by the Leukocyte blast. At the outskirts of Tsukigase Dam, Gai briefs Funeral Parlor that their next mission is to attack the dam where the Leukocyte control system is located but due to the Leukocyte's security system, he will have Shu use Kenji's Void to disable it. Shu rejects Gai's plan since it means a percentage of them might die, but his words aren't heeded by everyone else who follows Gai and runs away until Inori goes to talk to him. Meanwhile at Tsukigase Dam, Major Segai informs Shuichiro Keido that his men are prepared for Funeral Parlor's attack including Daryl, who wants revenge against the Undertakers for stealing his Endlave Steiner. As Gai gets another blood transfusion in a room alone, he confesses to what he assumes is Inori. He reveals that Shu's words had affected him and the difficulty of shouldering the weight of responsibility for the lives sacrificed for him causes him to question his resolve. Shu was in fact the one eavesdropping and after a brief exchange Shu comes to understand Gai's burden a little: he needs to appear as a strong leader for the sake of Funeral Parlor's stability. The operation begins and Funeral Parlor distracts the GHQ forces guarding the dam allowing Shu, Gai, and Kenji sneak into the Leukocyte control system with Inori defending them. As Gai and Shu hack the control system with Tsugumi's help via Funell, Segai sends Daryl's Endlave to stop them which Gai battles and defeats. However Daryl damages the control system, causing Leukocyte 1 to malfunction and plummet out of orbit into Tokyo. As Segai shows up, Gai (having known about the transmitter all along) makes a deal with him to use the transmitter to stop the satellite, since it is supposed to act as a marker for an orbiting Leukocyte to fire on if activated. In exchange Gai asks Segai to delete all of Shu's data in relation to Funeral Parlor. Gai then steps out while waiting for Leukocyte 3, Leukocyte 1 and the transmitter to line up. Shu, realizing that Gai is going to sacrifice himself and again questions if he is going to just watch or act. At this point Inori heeds Shu's wish to act, which causes her Void to fuse with Kenji's creating a powerful Laser weapon which he uses to destroy both satellites just as their paths intersect. With the operation over, Shu finally accepts Gai's offer and joins Funeral Parlor. Elsewhere, Shuichiro speaks with a mysterious blond youngster over the imminent awakening of "Cocytus" who would be seeking a "King" as Gai and Shu look up at the aurora borealis. (Source: Wikipedia)
