A/N: This story starts from Masamune's childhood when he still used his childhood's name (Bontenmaru).
Prologue
Kojuro hated those eyes. Where the right one had been was now covered by an eye patch. It was a cold reminder of that fateful day, in which the life of his young master had been ruthlessly changed for good, and all the spirits he had seen in the left one had vanished completely.
He hated the world for condemning the owner because of them. After the incident, nothing but pitying looks and scornful comments had been tossed in the boy's way. Even his mother Yoshihime had fled back to the Mogami clan after her son's tragedy. With only one eye, how could he be qualified as the Date clan's heir?
But most importantly, he hated himself for being unable to do anything about it. After Bontenmaru had lost half of his sight, he had erected invisible walls around him and had refused any contact with the outside world. The boy was still as dutiful and diligent as ever, but it seemed his soul had left him along with his right eye. Now he was merely a shell of his former self, a lifeless doll driven only by duty.
'It might have been better if I hadn't had a heart.'
The boy had commented in almost a whisper in his one and only moment of weakness.
Kojuro wished with all his soul to prove him wrong, but he had no idea how. For now, he could only watch over his master and do his best to educate him.
In order to survive, Bontenmaru had thrown away his heart. If only there was someone to give it back.
