from left to right ^^ -

Blade- Blade is the youngest of the brothers, he is the clown of the group, sometimes a bit aggrivating. But honestly its not a problem, if your down, he'll bring you on your feet. Blade is a master of the nin-jutsu ninja arts, he perfers melee combat over weapons.

Ying (top)- Ying is the 2nd oldest of the brothers, he's very loving toward all. He gets his strength from the need to protect others. Unlike Blade, Ying loves to use whatever he can get his hands on to beat your ass. He doesn't mind breaking the rules against the baddies, his undying love for Kaeko gives him will power. He's a father of two. however, kae is expecting later on in the comic and still has been undecided..what the second child will be.

Neon (bottom)- He's the oldest, strongest and ruthless brother. He separates from the three way back and becomes a Sol Assassin. Not much in known about him, he wears a mask to conceal his identity. Neon fights with his fists, 2 large claws attached with his gloves and sly traps, being an assassin his kills are most the time unseen.

Blaze- Blaze is a smart ass, completely. He loves nothing more than to prove you wrong, he's immune to all poisons. And is a master at concocting any antidote, poison, medicine. You name it. He likes to battle with poison tipped needles and a short katana. Blaze is very stealthy, he doesn't talk unless its to answer a question or voice an opinion.

^_^ look forward to the coloured version
