The Broken Prince

Natsume disappears for two years without a trace after saying he was going to go on his own little adventure through the mountains. Nobody thought of it as no one wanted to freak out the Fujiwara's. Except Nyanko sensei knew something was wrong as he could not even see or sense Natsume as he would fly around the mountains often. Worried Taki, Tanuma, and Nyanko sensei goes and finds the lost boy.
