Akuma No Tenshi No Ai Volume 1(The Demon's Angelic Love)

Prologue

I run while holding my little sister's hand. I have never seen something scarier than that, a group of men from nowhere attacked my clan just after we killed a level 4 oni (demon) at a school. I look at the back and I can see 3 men in robe are following us. I tried to find a place to hide, but it looks like there are only closed shops around here. Suddenly, something catches my eyes, an old building. We run in full speed, but suddenly my little sister stopped running.

" Why did you stop running, Nina!" I yelled.

"Nii-san...it hurts, my feet hurts" Nina answered.

When I look down I can see blood flowing from her feet as she stepped on glasses on the floor. I have no choice but to carry her. In the old building, we hide behind a {pole/huge crate} , and hoping they won't find us. I tear up my shirt to cover Nina's wound. Suddenly I hear several footsteps coming from the back. I take out a long knife from my back, and I will try to ambush them. I get out from the hiding and try to stab one of them but his hand is faster than my movement. He grab my neck and smash me to the ground.

"Nii-san!" Nina scream in shock.

"Ouh, I never thought there will be an entertainment tonight." Said the guy who's choking me.

That guy let go off my neck, he stand and walked towards Nina. I grab his foot to stop him. He look back and walk towards me. He step on my chest.

"Argh!" I shout in pain.

" Stop, please stop, I beg you." Said Nina.

The other two guys went to Nina. One of them hold her hand still, while the other one summon a bright fire on his hand. He tear up Nina's shirt and draw something​ on Nina's abdomen using his fiery finger while Nina cried in pain. I can't do anything other than watching my sister being tortured, I'm such a hopeless and useless brother. I feel my body become hot, I'm loosing my conciousness.

"Nina, Nina, Nina." I whisper before I collapse.
