Fairy Tail- Plunder (Male Reader)
(F/N) is unable to use magic. One day, his family is murdered by a dark guild. Soon after, on a dark and rainy night, with only a sword, (F/N) kills every member of the dark guild. Natsu's team had been camping out nearby and heard everything going on. When they found what it was, they were shocked to find dead bodies lying all over the ground. After (F/N) says he killed them because of what they did, he walked away. But suddenly, the sky opened and lightning struck him. He wakes up in Fairy Tail, where shortly after, he found out about his new powers.
