Koneko x OC Brother

Punishment (Finale)

*Soren POV*

I woke up confused for a second before I remember the events of yesterday. I came back to the ORC and Kuroka confessed her love to me, and now I'm in her bed. She's snuggling into my chest, occasionally purring. I suddenly hear yelling upstairs, curious, I make my way to the ground floor. The yelling is around the corner, so I listen in.

"Soren will kill me Rias! Please don't tell him I was here! I'll leave for a while until he calms down okay? Just don't let him find out!" I hear Issei, I grow angrier by the second as I remember he forced himself on Koneko. I round the corner and speak.

"I already have" I say, Issei turns toward me with a look of fear on his face, and Rias has a small look of concern.

"Soren! Please don't kill me! I'll never even look at your sister again! I promise!" He yells in fear.

"I'd normally forgive you in time for just looking at Koneko. But you've crossed the line Issei, you forced yourself on her and took advantage of her. So I have 2 punishments for you." I say, he gulps but stays quiet, not wanting to anger me further.

"1, I will never forgive you and if I ever catch you looking at Koneko the wrong way I'll break a bone. And 2, and since this is a punishment I won't allow you to refuse." I say pausing, him tensing up at the suspense.

"Issei Hyoudou. I challenge you to a battle." I say, appearing in front of him and teleporting to an abandoned battle field, I put a magic barrier around the arena, and slowly everyone else appears, most likely Rias brought them.

"Now, I may hate you with all of my being right now, but I'm not a monster. If you win, I will personally guarantee that you get a harem, and you know that's in my power." His eyes widen and a perverted smile appears on his face. Disgusting.

"However, if I happen to win Issei. 'I pause, gaining a smirk' You are never allowed to touch another woman, not even with your eyes!" They may be stupid wagers but I know it'll encourage the pervert to actually put up a fight. His eyes actually tear up at the thought, but he quickly shakes them away and gains a determined look.

"I will win Soren! You can count on it!" I inwardly smile, happy at the possibility of this being a fair fight. I look over at Rias and signal her to do a countdown, manifesting a microphone for her to speak into. Her voice booms throughout the arena.

"This is a match between the challenger, Soren Toujou, and the challenged, Issei Hyoudou. The match will be over when 1 of the 2 is unable to fight any longer. Issei Hyoudou has permission to promote. The match will begin in 3 'Issei and I get into fighting stances' 2 'We lock eyes' 1 'He yells out balance breaker, but I wait to use mine' Begin!"

A loud boom is heard, most likely the sound barrier breaking as we both rush at each other with insane speeds, I'm still holding back my speed and power so this fight lasts longer. We both match the other's punches and it goes on like that for about a minute, I see a break in his defense and go for it, knocking the wind out of him. I roundhouse kick him in the face and send him flying into a nearby building. I smirk as his aura grows tenfold, as he walks out unscratched.

BOOST is heard a few dozen times. He rushes at me with about 3 times more speed than last time, I match his speed yet again and go a little faster. I hear his grunt of annoyance at my speed as he does what I was hoping he would.

Balance Breaker Overbooster! Explosion! He starts attacking with his full power, and speed. I struggle a little and fall back. 'Now this is a fight!' I think, time for me to get serious.

"You better get stronger Issei! Because I'm gonna start fighting now!" He only growls in response as my body radiates a black aura.

1st Longinus Balance Breaker! Damnation Armor! A voice yells from my body, a giant mace appears is my hand as armor forms around my body. 'picture at top, hopefully it's actually there this time'
