Behind The Mask

Im Klouis Lambert. Im the brother of the renowned ultimate mage named Erisa Lambert, im on my way home when my best friend told me to go to someone's house, and it's urgent, so I rushed my way there knowing nothing. It literally shook me when i saw a coffin but dont know who it is. I started to go near to it to have a glance. But what i saw is imaginable. The body was torn apart, but one thing that im sure and hoped it's im mistaken... ....it's my sister! It's really is my sister! i know it's her because of her neck it has a star symbol, which symbolizes an apprenticeship with a well-known master. My body can't move in shock. I put my palm on my mouth, hoping not to puke. What they did to my sister is so inhumane. "To think that you'll come back to me like this?.......you're really worthless idiot." Someone beside me said when i turned my head right, i saw a girl holding my sister necklace. Without any confirmation, i know these words are meant for my sister. So, without thinking twice, i use all my powers to send the girl to hell. The girl looks at me. "You dare to do that." It coldly spoke to me.Out of anger, he shouted at her. "How dare you speak to my sister that way." She seems to be investigating me by looking from bottom to top "Interesting, be my apprentice." After that, the girl threw the necklace of my sister to me, and a tatoo appeared on my back. I know because i felt the burn in my back. I didn't think much about that because my priority now is my sister. To this day, i promise to myself that I'll avenge my sister no matter what and kill it the most painful way i can.
