Tunnels on a Dark Night

In her safehouse, Karin finds out that all three Digmas have Atlas AAA ranks, which means they are highly regarded. Takehiko reveals to Kuniko that he was sent by Atlas to guard her. But he has decided to kill her and end Atlas' plans when he found out that they sacrificed children to build the city, including his sister. Kunihito arrives just in time to save Kuniko before Takehiko can kill her. Losing all hope, Takehiko tells Kuniko that AAA rank individuals will inherit Atlas, and he seemingly kills himself by jumping into a storm drain before Kuniko can stop him. Kunihito informs Kuniko that he has quit the army and will try to find his own way. Karin buys Akihabara as her "house". Mikuni and Sayoko arrive to seek refuge at Karin's territory, and place Miiko/Hiruko into a pool for safekeeping. Karin finds out the hard way in pleasing Mikuni. Kuniko and her team investigate the Metal Age's Nerima base, which has lost contact. They discover the entire Nerima base dead from exposure to photo-oxidants spread by Daedalus. Leon takes care of his brother Sion's injury caused by Ryoko's latest beating and tells him to quit if he doesn't like his job. But Sion tells Leon that he doesn't understand him. Kuniko goes to the three old otakus to buy a bomber, but is referred to Akihabara's newest leadership, Karin. Kuniko reveals that she wants to use the bomber to burn Tokyo to the ground, to Karin's shock.
