Potentially Dangerous

We see a handsome man who seems to be in his early 20's. He has shoulder length crimson hair and blue eyes, similar to Rias. In fact, some say he is the male version of Rias.

This man is Sirzechs Lucifer, formerly known as Sirzechs Gremory, he is the Satan Lucifer who is in charge of Domestic Affairs.

He is the former heir to the Gremory Clan, the eldest child of Zeoticus Gremory and Venelana Gremory and the older brother of Rias Gremory. Sirzechs is also the husband of Grayfia Lucifuge and the father of Millicas Gremory.

Known as the Crimson Satan, he is the leader of the Four Great Satans who ruled the Underworld with the title of 'Lucifer'. His peerage is said to be the strongest group in the Underworld.

He and his family were currently situated in the viewing box, a place where they could spectate the ongoing Rating Game. It was invisible and indestructible, so nothing could potentially hit or damage it.

"He's one hell of a fighter, isn't he father?" Sirzechs looked at Zeoticus, his father.

Zeoticus has the appearance of a middle-aged, handsome looking man with long crimson hair that is tied in a loose ponytail with a black hairband.

He also has bright blue eyes just like his two children, Sirzechs and Rias Gremory. He also has a short and red beard or stubble.

Zeoticus nodded. "He is. But I didn't know he was the Red Dragon Emperor though. Grayfia, remind me why did you hide that fact from us? " Zeoticus asked Grayfia who bowed.

" Apologies, Lord Gremory. But I thought it would be a good surprise for you all." Grayfia apologized.

" Well it certainly was a surprise for us when we heard 'Boost'. I haven't heard that in a long time. " Zeoticus replied with a nostalgic look on his face.

" Mommy, I'm scared. That guy is so scary." Millicas, Grayfia's and Sirzechs son whimpered. He hugged Grayfia's leg.

Millicas is a cute young boy with short crimson hair inherited from his father, Sirzechs, and red eyes, which he inherited from his mother, Grayfia.

"It's going to be alright, Millicas. We are all here to protect you." Grayfia whispered as she hugged her son. Sirzechs was focusing on the fight though.

'His aura feels like a dragon more than anything. This has never happened with the other users of the Boosted Gear before, how interesting. ' Sirzechs mused.

Back at the confrontation. Issei was staring at Riser's horrified expression with a stoic look of his own.

Issei slashed his broadsword horizontally, sending out a massive wave of orange fire towards Riser. Riser flew up with his fiery wings, dodging the attack. The ground under him exploded.

*BOOOOOOOOOOOOMMMMMMMM!!!!!*

Issei disappeared and reappeared above Riser. He glared at him. He raised his flaming broadsword in a high stance.

He flew down towards Riser, his weapon leaving a large flaming trail behind it.

"Blazing Meteor!" Issei muttered and slammed the sword into Riser's face.

*BAAAAAAAMMMMMMM!!!!!*

Riser spat out large amounts of blood as his body was slashed cleanly in half. His falling body was burning while all of it was happening.

*BAAANG!!!*

Riser crashed back down to the flaming ground. Issei floated on the sky while looking down at where Riser was.

A few seconds later, Riser emerged from the flames with his body fully regenerated. He was breathing heavily while looking at Issei.

Issei appeared on the ground far away from him.

"Boost!!!"

"Hell's Vortex!" Issei shouted out and slashed his sword downwards, sending a large spiral of flames towards him.

The flames were spinning so fast that it turned into a large black ball that had a red tint surrounding it.

"I won't let you win!!!!" Riser shouted and fired a large fire beam towards Issei's attack. It did nothing as the black ball dispersed the fire beam easily.

*BAAAMMMMMMM!!!!*

Riser spat out more blood as the black ball crashed violently towards him. His face and body were deformed instantly.

He was sent flying back to the remains of the school building. *BOOOOOOOOOOOOMMMMMMMM!!!!!!*

Suddenly, a black dome exploded out of nowhere, engulfing and decimating everything in its path. Issei appeared far away from the ongoing destruction, not wanting to be injured by his own attack.

Rias and her peerage were hiding behind four layers of magical defensive barriers cast by Akeno and Rias.

Ravel used her wings to stay floating in the sky and far away from the destruction. She couldn't believe it, her brother was losing. And by the looks of it, Issei didn't even break a sweat using that attack.

The dome disappeared, a large barrier of smoke followed it and covered the entire area but everyone could see a building sized crater hiding behind it.

Riser was lying in the middle of it, he was breathing heavily. It took literally all of his demonic power to regenerate his body back to pristine condition. His sanity was lost, he had lost the will to keep fighting.

All he could see was the blazing broadsword stabbed to the ground in front of him. Issei was nowhere to be found.

" Boost!!!"

"What.....What is he going to do." Riser asked between heavy breaths. Suddenly, a giant shadow covered the crater he was lying in. Riser looked up and was horrified.

"ROAD ROLLER DA!!!!!!"

*BAAAAAAAAAAMMMMMMMMMMM!!!!!*

Issei grinned maniacally as he slammed a giant road roller into Riser's body. He had found this staying idle in the backyard of the academy. He didn't know why, but he needed to do a Jojo's reference.

"Boost!!!"

A dangerous dark red aura surrounded him. Issei was extremely irritated and angry. Riser wad stubborn and wouldn't give up. Well, maybe this would make him give the fuck up.

"MUDAMUDAMUDAMUDAMUDAMUDAMUDAMUDAMUDAMUDAMUDAMUDAMUDAMUDAMUDAMUDAMUDAMUDAMUDAMUDAMUDA!!!!!!!!!!!!!!!"

Issei shouted crazily as he kept punching the road roller repeatedly with his fists. The road roller started caving into the ground. Issei kept punching until he ran out of stamina.

"I'M GONNA KILL YOU!!!!"

"BOOST!!!!"

*BAAAAAAAAAAAANGGGGGGGG!!!!!*

The ground exploded once more, blood splurted everywhere. Issei breathed heavily as he stared at the pool of blood under the destroyed road roller.

"Riser Phenex has been retired!!! Rias-sama's team wins!!!!"

"WWWRRRRRRRROOOOOOOOOOOOAAAAAAAAARRRRRRR!!!!!!!!!!" Issei roared dominantly at the sky, spewing out a large sea of flames from his mouth. He felt the dragon inside him controlling his actions for the moment.

Issei stopped his show of force and grinned. Grey smoke was rising out of of his mouth.

"Issei!!!"

Issei looked at Rias who climbed up the road roller and ran towards him.

"Issei!!" Rias shouted and jumped towards him. She wrapped her legs around his waist and hugged him tightly. Issei chuckled and hugged her back endearingly.

"We won!" Rias squealed excitedly. She then looked at Issei who gazed into her blue eyes.

"Ise. I love you... I love you more than anyone else... " Rias whispered to him. Issei smiled warmly at her.

" I love you too, Rias. No more hiding secrets from me, okay?" Issei asked her. Rias nodded.

"I promise to never let you out of my sight, Ise. " Rias whispered while caressing his back.

" Kiss?" Issei asked her. Rias blushed deeply.

"My whole family is watching, Issei. " She whispered. Issei smirked.

" Then let's give them a good show. " Issei whispered in her ear, making Rias blush even more.

They looked at each other while their faces were inches away from kissing. They leaned in fully.

They kissed.

"Chu!~"
