"Courage is resistance to fear, mastery of fear -- not absence of fear." -Mark Twain

Alone in the world. The only voice: an echo. The only friend: a shadow. Is salvation possible?

Christmas: a time for joy, cheer, and friends. What happens when you have none of that? 

. A girl afraid of attention. KAT-TUN. Japan's most prominent band. When these seven meet, it should mean a new life. At least for . But traumas are not easy to get over. Can she overcome her fear, and accept love from six people? Moreover, can she learn to love again?

Six friends + all male + one singing group = too much time together. Add a lack of love lives and well, you can imagine what happens.

Takenaka Yuta is in love. Not weird. Except his love is one of his best friends, Azuma Wataru. Again, not weird. At least not in the Boys Rhythmic Gymnastics Club. However, why can't Yuta tell him?

The SixTones, Johnny Entertainment's newest band, would never have guessed that a small request from their senpais would lead them to a world full of fantasy, and danger. Chosen to be the next group of "Color Angels", do these six boys have what it takes to defend the world AND their friends, plus juggle the expectations of a debuted band?
