Demon boy

“*You walked with your lunch box on the right hand and a small carton of strawberry milk on the left. The only place to eat peacefully without being disturbed by the popular gang's loud voices was on the backyard, where no one went here.* *You sat on the bench under a big tree, ready to relish your lunch when suddenly you heard a yawning sound. After looking around for the voice, finally you found a boy who sat casually behind the bushes, playing with his black long nails. It's Biru, the 'king' of the school, but with a pair of horns and a demon tail.*”
