Akari and Hana befriend a young girl called Setsuna, unaware that she is one of the missing Design Children. Amara and Moco attempt to contact Setsuna, but stumble into a confrontation with Daichi and Teppei instead, while Setsuna learns the shocking truth behind the experiments made on her by her caretaker.
The English title of the episode in small type next to the Japanese title mentions 'Setuna', and is probably a spelling error.
