Siblings in the Atmosphere (大気圏の兄妹 Taikiken no Kyōdai) is the 14th episode of Kakumeiki Valvrave and the second episode of Season 2. It first aired on October 17, 2013.
Having made it past the Dorssian blockade, the Valvrave pilots return to the transport ship for a breather while Akira refuses to leave Unit 06. Afterwards, Takumi outlines a course to the Ookuma District. Later, as rumors of Akira's past are held in check, she reluctantly leaves the safety of Unit 06 and upon running into Marie, the two share a tender moment with respect to having Shōko as a mutual friend. Afterwards, the New JIOR transport ship successfully commandeers a landing shuttle and feigns clearance through the Space Station's Follow Rings, despite being discovered by the Dorssians due to Satomi's judgement. As Satomi blames himself and recalls how he failed to defend Akira from being bullied after she was caught hacking a school entrance exam for him, the Valvraves soon overheat, leaving the shuttle defenseless. Although Akira selflessly defends the shuttle, Unit 06 finds itself thrown out of the Follow Rings and beyond help. However, Haruto manages to get to Akira after defeating the Dorssian mecha using a new Familiar weapon. Thinking fast, Akira hacks into the ground control radio transmissions and Satomi manages to decipher a new landing trajectory which allows the shuttle to rescue Units 01 and 06, much to L-elf's hesitance. Now way off-course, the ship plummets through Earth's atmosphere and eventually crash lands deep within Dorssian territory.
- The box Akira uses to sneak out for food in has the words "SUN⚫️RISE" written on it, Sunrise being the creators of the anime.
