The Singing Knights Project

A Rabbit Hybrid, A Brit, and An American. these three have been chosen to become what the government calls 'Singing Knights'. The Singing Knights are very powerful singers, trained in very different ways but have a harmony together better than soldiers who have been to hell and back together.
Sam Gladiator was trained to use his natural tenner voice to hypnotize, then he becomes, who his trainers like to call, Mas, to control and become victorious.
Joey, or Taurtis, was trained in using his voice as a Alto to help increase Sam's power. He chooses to sing certain songs that lead his power of body manipulation, making his victims his puppets, stronger, and songs like those have been proven to be his weapons of choice.
Grian was trained in bass, his most lethal note killed three armed men with only the one sound, he can be persuasive when he sings, and can be very manipulative.
These three are best friends, more like brothers since childhood, and will do whatever it takes to protect each other, protect their family.
When the government sends them to Tokyo, Japan to go into hiding, two of those singers develop a more intense relationship with each other, things become more dangerous when they become a couple, their combined powers will be very dangerous.
