9 Young Devils Tournament: 2

After surely not going overboard on the dispatching of Diodora and definitely not traumatizing him of that event Sebastian teleported back to the arena waiting room.

Arriving back in the waiting room to looks of mainly looks of fear, some of respect and a few of awe Sebastian just ignored them all and went to take his seat next to Sona again.

"Well done brother I knew you'd win! I dont know what that guy did to annoy you but he probably deserved it!" Sona said "Y-yeah well done S-Sebastian you did great!" Rias meekly shouted out.

"Well thank you but I look forward to both of your matches and I'm sure you'll do well in them" Sebastian said and smiled at both the girls causing them both to blush the same colour as Rias's hair.

Many of the crowd outside had different views of what just transpired in the arena.

Members and supporters of the old Satan faction thought Sebastian was showing he was a 'true devil' by displaying his power to those weaker than himself, The new Satan faction thought it was excessive but he must of done it for a reason.

The ones who belonged to no faction didnt really know what to think, some were shocked that two children fighting would be that brutal but others opinions seemed to coincide with the two Satan factions.

The members of who were few of the rapidly rising terrorist group know as 'Khaos Brigade' thought Sebastian would be a great ally if he could be swayed to their side.

The matches progressed on some, others winning others losing and the opponents Sebastian fought either all resigned as soon as the match started or were quickly despatched but not to the intensity of Diodora's beat down.

Eventually from winning their matches and leading to the closing few it was time for Sona vs Rias and the prize? Sebastian has to take the marry the winner which he by no means agreed too or had an opinion in.

Appearing on an island in the middle of a dried up lake bed Sona and Rias glared at each other for a few seconds before Sona decided to speak "You will lose you know, big brother is cheering for me afterall and I will marry him" to which Rias laughed at "Fufufu it's funny you think Darling would cheer for you instead of his future wife but if you can beat me I'll consider letting you be his mistress"

"No! wife will be mine!" Sona shouted throwing a literal tsunami at Rias to which she flared her power of destruction destroying the water before it could touch her. Rias once again flared her destruction power throwing blasts of it at Sona who made barriers of water that exploded on contact with the the volatile blasts of energy.

The crowd watched with bated breath at every magical blow and rarely a physical blow when they got close enough to each other exchanged between the two of them.

The landscape around the two was battered with deep gashes in the surface of the simulated world or holes in the sides of the dried up lake beds sides where attacks were either deflected or missed

After sending spells, punches, kicks and other various means of inflicting damage on the other both Sona and Rias where tired out and slowly lost momentum in their attacks.

"This will be the last one Sona! put everything you have into it" Rias shouted as she gathered as much destructive energy as possible in between both of her palms.

"Your going down Rias!" Sona shouted just as loud, swirling water formed in her hands creating a vortex.

Both of them released their attacks at the same time causing the water that struck the destruction to turn into mist and block the viewers sight.

The arena was quiet and no one spoke to not miss even the faintest noise that came through the transmitter.

The mist slowly cleared to reveal Rias lying on the floor breathing heavily and the same with Sona but on her knees.

"You know Sona I'll let you be the mistress" Rias said in a small voice before falling unconscious and leaving a grinning Sona behind.

"The winner is Sona Sitri! we know move into the semi finals!" Naud announced making the viewers erupt in a cheer of excitement.

Sebastian, not that he would lose, was preparing for his next two fights to end the tournament. His new staff was proving very useful as a medium for casting spells without much effort but with a missing sword to sit in the staff's sheath it didnt feel complete and as such a sword would need to be added.

"Next match Sebastian Sitri versus Sona Sitri! The winner advances to the final!"

Sebastian stepped into the teleportation circle leading to a clear open circle in the middle of a forest.

Sona and Sebastian stood around 10 metres apart from eachother both calm and collected.

Sona was still breathing heavily and look exhausted presumably from her earlier match with Rias, she couldn't fight well in that condition but her pride as a devil wouldn't cause her to back down but her overwhelming bro-con tendencies just might.

Sebastian dropped his staff to the ground letting it fall into his systems storage space disguised as his separate space for storing weapons and walked over to Sona who looked about ready to faint.

Putting a hand on Sona's cheek to which she blushed at Sebastian flashed her a smile and started speaking "I'd hate to see you get hurt Sona and I'd much rather It would not be by my hand and your exhausted so please retire Sona and get some rest, I'd rather not hurt my cute little sister"

Sona's face went the same colour as Rias's hair as she meekly nodded and made a weak "hnn" as an agreement not being able to do much more due to her embarrassment.

"I'll see you after I win this then Sona make sure to cheer for me" Sebastian said as he took his hand off Sona's face and continued to smile at her.

"I-I resign" Sona said which caused her to burst into white particles and be teleported out of the area.

"Sona Sitri resigned. Winner is Sebastian Sitri! Next round is the final! we'll take a short break before the final."

Sebastian was teleported out of the arena in same manner as Sona arriving back in the waiting room for next match he decided to meditate for a while until his fight to decide who the strongest devil kid is.

Sona and Rias sat in the medical area having both recovered from their exhaustion, obviously nothing being wrong with them other than being tired but the on sight medics from the Serafall memorial hospital took their jobs seriously and had to check them over for any injuries.

Both of them sat in silence not really having anything else to say to eachother before Rias started to speak "Your strong enough to be Sebastian's mistress so maybe we can work towards you being the second wife" she said holding out her hand for Sona to shake "Sure I'll play along for now but dont blame me when you become the mistress" Sona said shaking Rias's hand sealing the deal on their new found sisterhood.

"Its time for two young devils to duke it out for the title of 'the strongest kid devil'! Final match Sebastian Sitri versus Sairaorg Bael!"

On that day the greatest bromance the underworld had ever seen was born.
