A cute fighter (male y/n X yami sukehiro)

You are a 5'5" male, who had been kicked out of the Royal Family: Agastami Manor. You are the oldest brother of two. Nik a vice captain and Alex a tryout. Your parents had hope in you, but you let your anger control your body and mind; putting siblings at risk with your Earth Manipulation Grimoire..
However, it all changed when you reached 16: they kicked you out. No. They sold you to be a test subject. You remained there for 3 years, slowly being transformed into an emotionless killing machine and weapon. They forced surgeries and adjustments to you, to your body, but most of all, your brain.

Due to the heavy training and permanent differences on you, abilities like fire and wind creation had developed. Your Grimoire was feared upon the others in the same chambers. You wielded a fire sword, that cut through most magic, even its opposite: water.

During this story, Captain Yami, 22, has been a Magic Knight Captain for two years. You'd heard rumours that the group named The Black Bulls was a 'club', containing Henry, Vanessa, Magma, Charmy, Luck, and Finral. They were always last place, but in battle, they were the best.

Your strong rage during training killed and mutilated most of the other test subjects, and guards. Amongst the rubble and blood, you could be found in the midst of it.
A man looming at 6 feet tall, wearing a white tank top, black, or brown, trousers, a ruffled up cape with The Black Bulls' crescent, and dark leather boots. A book holster wrapped around him for his own Grimoire, with a katana holster, too. A lit, and burning, cigarette was held between his fore and middle fingers. He recruited you, and you both slowly fall, head over heels, for one another after your first mission...
