Lost tribe

Mosu Yamamoto, a teen Japanese boy, moves to a rainforest is Peru due to his fathers job as a botanist. All his life he looked for adventure wherever he could find it. It was exciting and all but there was always something missing. He was alone. Besides his parents he didn't have anybody. But he didn't think of it as much as he had his comic collection, the lost tribe. As they are in Peru, as usual mosu looks out for adventure and he got one alright. In the depths of the rainforest, he almost had been eaten, literally, by a ferocious tiger but the spear that killed it was the spear that just about saves his life, and what about the person who threw it? Maybe he wouldn't be alone for much longer after all...
