Cobalt, Chrom, Kei, and Neon are androids living together in an abandoned house. In order to pay off a huge electrical bill, the four decide to compete for prize money at the Babel entertainment tower. After their first performance, they meet Esora, a boy struggling with the recent loss of his father. The encounter activates a special program within the four androids.
But why?! I'm more like 
an older brother than you, Neon!
!لمَ؟ أنا أشبه بأخٍ كبيرٍ لك يا نيون
Wieso? Neon, ich bin älter als du!
Neon
Neon
NEON
Perché?! Io sono più grande di te, Neon!
Mas por quê? Sou tipo como um
irmão mais velho para você, Neon!
Ну почему? Я ведь для тебя
всё равно что старший брат, Неон!
