He has dark hair, dark eyes, and pale skin, kind of like a vampire, but he is NOT one.
He is quiet, dark, and hardcore emo. Don't ask this kid stupid questions or try to make him be all happy go lucky. He will snap at you. He can be 'mean' and 'rude' but to him he's just being himself and speaking the truth. He is also in love with the Emo Trinity, Hollywood Undead, and Starset (THE BAND). He's always listening to their music. You do not take this said music away from him or you will have Hell.
Sadao is a shadow eternal, a transien, a telekinetic, and a whole slew of other things that won't be described at this moment. Sadao can also resurrect people's shadows, bringing them back to life for a short period of time. He can also travel to a strange place that is in between reality, DD, and the Shadow Plains.
Ryule and Aaron are his fathers. Seyzmon, Uriah, Nixie, and Aliska are his siblings. Reyn is technically his aunt but she feels more a sister. Kuro is sort of like a big brother to him. He is also slightly obsessed with Noemi's band Pure Infinity Insanity. Sadao is also close to Noemi's daughter Koke.
