Trainer? Killer? He is both.
When he was eight years old, he raised a carp king that no one wanted; when he was fifteen years old, the fish used his life to block the family's death from a knife that should have wiped them out.
The home is gone, and the escape route is gone. From then on, he challenged the gym during the day and climbed up the right path of the alliance step by step; at night, he received assassination commissions and wiped out every corpse that could not be seen in the black market - the world called him "Scavenger".
Nidoking, Gengar, Kuailong, Dream-inducing Tapir... None of the six elves came clean.
There were people in the black market snatching his orders, people in the alliance checking his background, and the person he once wanted to protect the most was finding out the truth bit by bit.
As long as he can hide it, he can live as long as he can.
