The Priestess - Freya

One of the students in the F-class was Dray. He was a simple-looking boy with black hair and black eyes. He has been in this school for two years now but he was still unable to improve his skills to the next level. Most of the other students looked down on Dray because he was still an F-class!

No one else knew it, but Dray had a seal placed on his body to block his power. He wouldn't be able to remove the seal until he was eighteen years and all of the power he has been getting till now was only being stored inside the seal. When the seal breaks, Dray knew he should jump straight into the S-class or even higher! But if he releases the seal before he becomes eighteen then he could die from the influx of excess power. He had to be careful till then.
