You grew up in the orphanage at Japan. You were pushed around like a dog. You learned to fight and protect yourself from bigger, abusive kids. At the orphanage you met your closest friends. Kenji, Yuto and Emi.

Kenji is the oldest but also the shortest despite his age. He's now a 27 year old guys. He's serious and prefers to stay close with you three. You are the second oldest and the smartest of the four. You are now a 26 year old, strong, independent guy who's not afraid to speak his mind. Yuto is the third oldest and honestly the soft boy of your group. He's now a 25 year old dude. He likes to hang out with you four and is mostly clingy towards you because you don't judge him. And finally, Emi. She's a 24 year old girl who is probably the girly girl. She is boy crazy and loves pink.

A few years ago you four got adopted by a Yakuza boss. And so your guy's assassin training began.

As the years passed. You four became the best assassin's a Yakuza boss could ask for. You became known as "Eagle" because of your special ability, Eagles eyes which help you notice threats from every perspective. Kenji became known as the "Flash" due to his fast legs. Yuto's nickname is the "Brute" because of his strength which honestly shocks most people due to his soft personality. And finally Emi, also known as "Phantom". She's called that because of her misdirection ability. Misdirection is a technique which diverts the opponents gaze.

Today you four were called at the office... The big boss called you four for a special job. You guys were getting ready and started walking at the big boss's office.
