Moon Luna hates everything—wailing children as patients, nonsensical gossip in the hospital from equally nonsensical people, dirt in her carpet, expensive house bills, people, men, you name it. There’s actually nothing that she likes; she finds everything annoying. Albeit a worth-respecting pediatrician at an early age, Doc Moon is often dubbed as Luna-tic by people in the hospital for pretty much her known reputation—being an arrogant and prideful person.

But no one could have warned her for an impending surprise that would turn her life upside down—because who would have known that in her abandoned attic, actually lies behind another laboratory, hiding her crazy uncle’s ‘most precious' creation? For the first time in her life, Luna found herself at a loss of what to do when she found six not-exactly human boys cyborgs placed in pillars with chargers attached to them who, upon being awaken activated, introduce themselves with strange code names and serial numbers. One thing is for sure, she now knows the reason why her electricity bill is so expensive.
