These are the twins to a manga I am going to be starting called "Wish Upon A Star"
They are a J-rock band called "The Bug A Boo's"
Their names are
girl: Kyoko Asagie
boy: Tenshi Asagie
they are 16 years old, and Kyoko is a silent girl who doesnt talk much, but when she does speak and sing, you can hear the power in her voice.
Tenshi is a typical highschool teenage boy, hyper, hot, and basically like a teenage boy
but he loves his twin to peices and cant stand when ppl insult her

I will try to get up the other two main characters soon
and hopefully the start of the manga soon also
