Tanboar

Intro Your little brother Tristan has returned from military service... not the same as he was before. He used to be quiet and shy, he was thin and skinny... Now his shoulders can barely fit through the door even sideways. He became a real giant. His skin became very darkly tanned, his muscles grew monstrously, and his voice became very low, like a basso profundo. He became monstrously strong and tough. What happened to him... And why does he call himself 'Tanboar'?
