POV-Deven 3rd

'That girl, she's not human' he thought to himself

(she is human, but she possesses a sacred gear, I don't know which one). He walked down from the roof and to the student council office. He needed to know about that girl. He Knocked on the door. "Come in" he walked in and everyone froze. He closed the door and saw the fear in everyone's eyes. "Calm down, I'm not here to fight, I have a question." he looked around and saw Saji in the corner staring at him as if he were death itself. "What do you need?" Sona asked. "There was a new girl registered recently correct?" He asked. "Yes, her name is Li Niang, what about her?" Sona asked. "She came here with my rival. That means she's a potential threat, she also has a sacred gear". There was another knock on the door. "Come in," Sona said. Koneko walked in. "Senpai, Bucho needs you to come to the clubroom." She said. "Ok, I will be there soon, also, if you follow that girl, be careful."

TIME SKIP

"Bucho, I'm here." Deven walked in to see a man with blonde hair holding Rias by the wrist. "What's going on here?" He was not happy. "Rias, who is this human?" Rias broke out of his grasp and walked over to Deven and grabbed onto his arm. "Deven, this is Riser Phenex, he is my fiance."...a pause….. "What?" he said in utter confusion. "She is correct, Rias-sama is to be wed to Riser-sama by order of the head of the Gremory and Phenex households" Grayfia Said. when the hell did she get here? "This was an arranged marriage?" Deven asked. "Yes, It is for the good of all devils." Riser said. "I will NOT marry you, Riser," Rias said as she held tighter onto Devens's arm. Ah, I see now. "You will, my beloved, and you will be mine." he walked over and tried to grab Rias again but was stopped. Deven pushed him back and grabbed him by the collar. Lifting him up like he was nothing "Listen ass-hole, I don't care how important you are, If you ever touch Rias Gremory again I will personally separate your head from your body and drag your soul down to hell." His eyes started glowing a deep red. "Deven-sama, If you do not release Riser-sama I will have to intervene" Deven turned his head to look at Grayfia with his glowing red eyes. "Stay out of this Lucifuge, you try anything and I will bring your unconscious body back to Sirzechs." Grayfias eyes widened in fear at his threat. She knew she did not have the power to stop him when he was angry. "Now then, you are going to go back home and cancel this marriage arrangement or you lose your other arm." he said with malice. "you-AAAAGGHHH" Deven grabbed risers right arm and ripped it off. Riser fell to the ground and his arm started to grow back "what the hell?" Deven asked as he watched Riser's limb grow back. "You fool, Phenex has the power to regenerate faster than any supernatural creature. I will not break the marriage agreement." Deven stared at Riser. "Grayfia," Deven said calmly. "Y-yes, Deven-sama?" Grayfia stuttered. "I need you to bring me and the bird here to an arena. Then please gather the heads of the Gremory and Phenex households to watch. Do you understand?" Deven said with no emotion. "H-hai Deven-sama." She teleported Deven and Riser to an arena then left to do what he asked. Rias and her peerage were up in the viewing area. "YOU FOOL, do you realize what you are doing!?" Riser yelled from across the arena. "I suggest you gather your peerage here. To make this fair." Deven said with a smirk. "You really are dumb." he snapped his fingers and his full peerage arived. They were all girls….. ALL OF THEM….. Riser explained to his peerage what was happening. Then the fun part arrived. "Lord and Lady Gremory and Lord and Lady phenex have arrived," Grayfia said over a speaker. Deven looked up and also saw a smiling Sirzechs. Deven then said two words. Two words that caused everyone who heard them to stop in fear.

"Balance Breaker"

The Vortex that surrounded him was darker and bigger than the others he used. The sky darkened and sparks flew across the sky. No one had seen Devens balance breaker. This was the first time. The vortex cleared and The figure who stood in its place was terrifying. The figure was large, a full head and shoulders taller than Riser. The armor was pitch black and heavy set. Two golden horns stuck out from the helmet. There was a red cape on his back and two glowing red eyes. The figures chosen weapon was a Greatsword. Equally as black as the armor. "Come, servants of the house of Phenex. Come meet your doom" Riser stood without fear. "Go my adorable pawns, bring me his head." eight girls rushed forward. Two had cat ears and paws. Two others had chainsaws. One had a staff. The last two used their fists. The one with the staff got there first. She swung for Devens's head. *CRACK* the staff broke on contact. "What?" Deven grabbed her by the head and slammed her into the ground, creating a crater. She disappeared in a blue mist. The two with chainsaws came next. Deven stood with his arms crossed. The chainsaws hit and broke after a moment. The two girls locked up in fear. He grabbed them both by the face and slammed them into each other. They were knocked out instantly. The cat twins jumped at him from either side. He caught them both and threw them across the arena. They hit the edge and were eliminated. The last two were knocked out by one swing of his sword. The two knights attacked next. One with a zweihander, and the other with a broadsword. He caught the zweihander with his hand and blocked the Broadsword. Shattering the zweihander, he grabbed the girl and threw her into her comrade. Both were eliminated. Next were the rooks and bishops. Both bishops started casting spells that had no effect. The rooks approached him. He raised his hand "Egredietur clientibus meis" four wolves raised from the shadows. They attacked the bishops while he dealt with the rooks. They both rushed in and landed punch after punch on him. They stopped after realizing that it was doing nothing. They stood frightened. "Spiritus est hydrae" he spoke. "Uhh….what?" Suddenly the face of a dragon took over his helmet. The mouth opened and a large stream of fire took them both. The rooks and bishops were eliminated. The wolves came back. He kneeled down to PET them. *BOOM* a large explosion suddenly hit him. He was obscured by smoke. High above, Yubelluna hovered with a smile on her face. When the smoke cleared, he stood unphased "What!?" she screamed. "Igneous imber" he held out his hand. And a small ball appeared. He threw it up at Yubelluna and out of instinct, she caught it. After looking at it….*BOOOM* an even larger explosion overtook her and she was eliminated. Deven then summoned a black pole axe. There were several things he wished to try on Riser. "BASTARD!" riser rushed in for a flame punch. Deven moved his axe in front of him just in time. Riser's hand hit the blade and he screamed. Deven pulled it back. The sickening crunch of bone was heard before Deven stabbed his spear through Riser's face then threw him to the side. He healed then charged again. This time Deven Spartan kicked Riser in the chest, causing him to fall on his back. He then planted the blade of his axe into Riser's chest and Dragged him back a bit. He pulled out his axe and Riser tried to crawl away. Deven planted a boot onto his back and stabbed him in the back. He picked Riser up from the back of his shirt. "Non erfuger potes" he hit Riser with the hammer of the axe. Effectively knocking him out. But he wasn't done.
POV- Rias 3rd

Deven started to slam Riser around. Stabbing and throwing him around. Destroying the arena and causing destruction. "What is he doing?" Rias questioned. "It's his sacred gear! It's trying to corrupt him!" Koneko yelled. She ran out to the arena. Ignoring the yells for her to stop. She ran over to the rampaging black knight. "SENPAI! STOP! You have to control it!" the knight turned and looked at the small devil. He walked toward her. He raised his axe but she stood her ground. "Senpai, please! I know you're in there!" he swung at her. "SENPAI!" she closed her eyes and waited. But it never hit. She opened her eyes to see the axe an inch away from her face. The knight was trembling. It staggered back and dropped the axe. Grabbing its head and roaring in pain. It fell to its knees and continued to roar. Then the knight went silent and limp. It fell forward and collapsed "Senpai!" she knelt down next to his head. "k-ko-ne-ko?" he spoke, then fell unconscious. The vortex surrounded them both. Inside the vortex was dark, but she could feel the armor melting away. The vortex cleared and Deven was in his normal outfit…...snoring
