Young Devil's Tournament: 1

Arriving in Lucifaad's arena the whole Sitri family, excluding Serafall who went to sit with the other Satans overlooking the competition, ventured into the arena to either find their seats or find the waiting room for the competition.

Walking into the waiting room for the tournament there were many different devils of different families ranging from some of the remaining 72 pillars and some from other unknown families.

Sebastian in his white cloak decorated with flower petal designs around the shoulder with a white under shirt including golden decorations on it that held it together. He also wore black pants with golden lines forming an X with a line in it of gold tucked into his leather boots. He walked into the room with his staff in hand eventually finding 2 saved seats beside Rias who waved at both him and Sona when she saw them.

"Hello there Rias it's nice to see you again" Sebastian said to Rias who when he said and flashed her a smile blushed the same colour as her hair "H-hello Sebastian I-im fine!" Rias quickly said while Sebastian chuckled at her reaction and Sona pouted that Rias was getting more attention off of her darling big brother.

While Sona and Rias made idle chatter, mainly about Sebastian, he took the took the time to look around the room and check out his opponents. He checked the rooms for a threat in this competition, which so far after checking around the room 3 times, he found no one to be a 'threat'. Other than Siaraorg Bael who was Rias's cousin nobody else would probably put up a decent fight for him, he knew later on Sairaorg was very powerful needing Issei's power of frien... power of boobs to defeat him.

Sebastian had memorized a lot of spells and could incorporate his Satan flames into them to a degree, he would be using the cool flames for this tournament, even though the matches would take place in a separate space enclosed in the dimensional gap with the same retirement system as normal rating games, Sebastian would rather kill anyone with his demonic blue flames.

"Welcome everyone to this years annual young devils tournament! This year we have quite the number of powerful young devils so place your bets now!" Said Naud Gamigin a sharply dressed devil in a suit of different colours. Naud was the main host of all media all across the underworld including rating games "Before we get started with the tournament here are the rules" Naud cleared his throat before starting "It will be a one on one elimination style match, in order to beat your opponent you must either: knock them unconscious, Do so much damage to them as to trigger the elimination system in typical rating games as to not kill your opponent or force them to resign." He gave a few moments for that information to sink into everyone's heads "With said let's start with the match ups, please advance to the field when your name is called, first match is! ..."

Sebastian watching the matches playing out on a holographic projection felt rather bored until he saw it was going to be his match next against an opponent that was yet decided and to be honest he didnt care as he we just overpower everyone in his sheer amount of demonic power.

Standing up and going to lean against the wall of the teleportation array, he walked away from the still bickering Rias and Sona, he didnt know what they where on about and he didnt want to know either.

Seeing the match end and his his opponent who was someone he hated from DxD it was Diodora Astaroth, Seeing him walk with the demeanour of a gentleman soon to be nun obsessed terrorist could offer pissed him off greatly causing his ever smiling face to break into a scowl if only for a moment but it was noticed by Sona who wondered what this boy did to earn the ire of her beloved elder sibling.

"Next match! Sebastian Sitri versus Diodora Astaroth!" Naud the announcer shouted out. Both of them stepping into the teleportation array appeared on a randomly selected generated environment which in this case was a barren flat grassland perfect for long or short range encounters as there was literally nothing blocking the way of anyone.

"Let's get this over with" Sebastian muttered under his breath as he looked at the supposed calm and smiling 'gentleman' in front of him. He knew what he was really like, recruiting heretical nuns of the church of which he had them cast out of by his own plans to later take them in only to break them and bend them to his will for nothing but the satisfaction and pleasure.

It disgusted Sebastian that Diodora did what he did but he would make sure atleast Asia didnt fall into his hands atleast if the plot of the world hasn't changed much from his birth into this altered universe.

Diodora still smiling with his eyes closed spoke "Shall we get started then?" while forming blades made of demonic energy which appeared dark green in colour around him.

"Glady" Sebastian replied forming a barrier around Diodora's conjured blades immediately closing the barriers in causing the blades to crack and break.

Sebastian produced a large quantity of water aiming it presicly to trap Diodora in "Wait! I resi.." being cutting off by the water consuming him which just as quick as it appeared froze into the shape of a beautiful rose yet made of ice. Sending a wave of his Satan flames with a great amount of air pressure caused the frozen flower sculpture to crack and eventually explode sending Diodora back to the waiting room or more likely the medical centre in an azure blue explosion of ice.

"D-Diodora Astaroth has retired, Sebastian Sitri is the winner!"
