Riser Phenex

The calm atmosphere in the club soon turned tense upon the arrival of the newcomer.

"Riser Phenex…" Rias muttered the man's name with some venom in her voice. "What are you doing here?"

"Oh? I can't even visit my own fiance?" Riser said as if he was unaware of the dislikeness that Rias had on him.

"I am not your fiance!" Rias said while gritting her teeth.

Touma looked at this scene with a frown, but didn't let it out on his face. He was bothered by the 'Young Master' vibes that Riser was giving off, now it only lacked him threatening others with his clan name and being bitch slapped.

"And the marriage is decided only after I finish college, so tell me why are you here, Riser Phenex!?" Rias shouted, but it seemed to go in one ear and out the other. Riser walked towards her with a mocking grin.

(A/N: I don't remember if it was after highschool or after college, but I will leave it as it is.)

"You see, my dear Rias, your fiance couldn't wait anymore and so our marriage was decided in two weeks time." Riser said, but as he was near Touma, he didn't bother to move away and tried to pass through. "Move, human."

Much to his surprise, when his shoulders hit Touma's, it didn't even budge at all even with his devil physic!

"Hmmn? You said something?" Touma asked, mocking evident in his voice.

"You…You dare!" Riser scowled and raised his fist, which was suddenly engulfed in orange flames.

Touma scoffed as he raised his hand and slapped the punch away and immediately brought up his other arm.

*Slap!*

Riser's head twisted in a weird manner as a red mark of a palm printed on his face. He stumbled back as his neck caught fire, similar to his fist previously and was soon standing properly again thanks to the 'Immortality' of the Phenex clan.

"Bastard!" Riser shouted in fury. He was the public image of his family, and being injured by a human would tarnish his and the Phenex's reputation, which is why he won't allow him to get away with that unpunished. The blond devil conjured the flames of Phenex and was ready to launch himself at Touma, however, he was ultimately interrupted by a magic circle that everyone in the room except for Touma recognized.

In a second, a silver haired maid with red lipstick appeared within the magic circle.

"That's enough!" She ordered, causing Riser to stop in his attempt of murder.

"Grayfia!" Rias called her in surprise.

She was Grayfia Lucifuge, the Queen of Sirzechs Lucifer and also known as the strongest Queen!

Riser clicked his tongue and obeyed her, dismissing the attack and his flames. He then walked towards Rias and sat next to her.

"I came with orders from Sirzechs Lucifer, I won't allow anything to happen." Grayfia stated, but then she looked around the room and saw Touma. She raised an eyebrow as she couldn't recognise him from anywhere.

"When the Strongest Queen says that, even I get scared." Riser said that in a carefree manner, but his eyes told otherwise as the fury contained in them would only calm down after killing Touma.

He proceeded to move his hand to Rias' crimson hair while the other went towards her thigh, but they were soon slapped away by Rias.

"Riser, as I said earlier, I have no intention of marrying you." Rias stated, much calmer now after recovering from her initial shock.

"You think our family will allow you to keep up with your selfishness much longer?" Riser asked in an amused tone.

"I have no plan on disgracing my family, but I also don't intend to just allow them to marry me off to someone like you." Rias said as she got up and moved away from him.

"Master predicted something like this would occur, so he proposed a Rating Game between you and your peerages to solve this matter." Grayfia suddenly interjected, causing everyone's attention to turn to her.

"I understand." Rias said as she internally thanked her brother.

"I already have participated and accumulated many victories, so participating in this one won't make any difference. But I have a condition."

"And that is?" Grayfia raised an eyebrow.

Riser pointed his finger at Touma. "I want him to participate."

Grayfia widened her eyes in surprise and turned her head to Touma. While Rias and her peerage had the same reaction as Grayfia.

"Wait, don't let him involv–" Rias panicked and disagreed immediately as she couldn't let her friend involve himself when he clearly wasn't involved in her mess.

"Very well, I will participate in this Rating Game on Rias' side," Touma said.

"Touma…" Rias was touched for a second, but shook her head and tried to stop him. "But…"

"However, even if I participate, what will be in it for me, Riser Phenex? As the one who proposed the condition, what will you offer?" Touma asked with a smile on his face.

"Such arrogance…" Riser's eyebrow twitched in annoyance. "If Rias wins, the Phenex clan will grant you a request as long as it doesn't put the clan in danger nor tarnish our reputation."

'Let's see if you can still smile after I burn you to ashes!' Riser thought as he sneered at Touma.

"Make it two."

"What?" Riser was taken back by Touma's words.

"I will accept it if the Phenex clan grants two requests." Touma pronounced as he demonstrated with his hand, making a 'V' sign with his fingers.

"V-Very well." Riser said, with his eyebrow twitching even more. Not wanting to deal with him anymore, Riser turned to Rias.

"Will Miss Grayfia approve and serve as witness to this agreement?" Touma asked as he glanced towards the maid.

Grayfia nodded, causing both of them to smirk for separate reasons.

Then Riser turned his head to Rias and a mocking smile appeared on his face.

"Besides, I want to ask this, is this your entire peerage, Rias?" Riser asked.

"And what if it was?" Rias said with a frown, causing Riser to guffaw and snap his fingers.

A Phenex magic circle appeared on the ground as Riser summoned his full peerage.

'Were they already waiting to be summoned?' Touma thought in curiosity, but remained silent to let the events occur.

Suddenly, a young girl from Riser's peerage kicked the ground and flew towards Touma at a speed that was difficult even for a newly reincarnated devil to accompany.

The girl thrusted her staff into Touma's stomach while her lips curled up into a mocking grin.

Touma looked at her with an untroubled face and took a step aside when she was almost reaching him. Then he clenched his fist and swung his arm. The back part of his hand made contact with the girl's face and sent her flying outside of the building to touch some grass.

Grayfia stared at Touma, her mouth slightly agape as she didn't expect Touma to be this strong, while the ORC members were the same. Meanwhile, Riser and his peerage stared at him in shock.

"It was self-defense." Touma said as he rubbed his hand with a hand towel to clean off the saliva that unfortunately landed on his hand.

His voice snapped Riser snap out of his shock and his brows furrowed in fury. He raised his hand and a fireball with the size of a head appeared.

"I will kill you!" Riser said and was about to throw it.

But one thing he forgo by rage was that he was in presence of the strongest queen, Grayfia Lucifuge.

A wall of ice surrounded Riser as the fireball was extinguished without damaging the wall.

"This is it. More than that and I will have to use force." Grayfia said as she glared at Riser.

Rider's fury doused by Grayfia's words, he grit his teeth and glared at Touma.

"Enjoy your life while you can, human, because I will make you regret being born." Riser declared as he instructed his queen to grab his pawn before disappearing in his magic circle.

*Sigh*

A sigh escaped Grayfia's mouth as she held her head with her hand. A rare moment where Grayfia broke her maid persona while still on duty.

"This became quite problematic." She said and then looked at Touma with narrowed eyes. "Are you confident in defeating Riser, sir?"

"My name is Kamiya Touma and yes, I believe that I can defeat him." Touma said confidently.

She continued to look at him for a second before breaking off and turned her head to Rias.

"And get stronger Rias, the current you can't defeat him." Grayfia warned before returning to the Underworld. "Good luck…"

After the strongest queen left, Rias sat on the sofa.

"Touma, why…?" She wanted to know why, why he would help her when he wasn't involved.

"It doesn't hurt giving a friend a hand, does it?" Touma asked her, not only that, he doubted that Riser could beat him anyway.

"Touma…" Rias' heart pounded fast, and a pinkish hue found made its way to her face. "Thank you…"

"No problem." Touma said with a smile.

"Ara~President and Touma-kun are flirting, should we leave the love birds alone?"

"A-Akeno!" Rias shouted as the blush increased.

Touma chuckled as he clapped his hands, gathering everyone.

"While this is fun and all, it's better if we all return home for today and rest. Because for the next few days, your training will be harsher than before, understood?"

"Understood!"
