Hire him if you want someone dead. Yoshi is a skilled assassin. He works with knives, guns, poisons, arson, basically, what ever you need. He always keeps a tooth from his victims as a way to remember them and as a nod to his last job as a dentist.. He lacks remorse and empathy, being raised in a gang means death is something he dosen't fear. He has no end goal in life, just to act as a dog and take orders from people who pay him.
