The Kawata Brothers

Despite his appearance, Zlyuka is a kind and peaceful person. He cares deeply about his friends and wants to protect and support them at all costs. His brother stated that he's not the type to beat anyone up, because Zlyuka is too kind for that.

Nakhoya is very protective of his younger twin brother, never wants to see him cry, and isn't afraid to get his hands dirty. He enjoys a good fight and a strong opponent. His opponents find him extremely difficult to read due to the constant smile on his face, which remains regardless of whether he's angry or tired.

Nakhoya is loyal to his friends, but his strongest loyalty is to his brother.

Unlike his older twin brother, Soya doesn't have peach-colored hair; instead, his hair is turquoise, matching his often hazy turquoise eyes. Unlike his brother, he doesn't have a constant smile, but rather a snarl with prominent veins. He is the same height and build as his twin brother – short and slender.

Nahoya is short and small-framed, but he manages to compensate for this with brute strength. He has a voluminous, fluffy peach-colored afro hairstyle, and he always smiles. He has fair skin with a light tan from time spent outdoors, and he is almost identical to his twin brother, except for his hair color. Nahoya often tries to match his brother's clothing, inverting the colors, but he is usually seen in biker gear.
