Best Kept Secret (Sona x Male Reader)

Chapter 4 - In the End

"So this is the Leviathans' power?" Usiel laughed. "It's Pathetic, he only dropped the temperature a little."

"I'm going to enjoy slashing you up." Izrail laughed.

"Both of you shut up." Zaphon snapped. "don't take him lightly, he did more then lower the temperature, if the temperature keeps dropping at this rate, it will reach absolute zero."

"Why should we care about that?" Usiel asked.

"Because even fallen angels can freeze to death."  You hold out your right hand and Ice forms, in the shape of a spear, around it. You throw the spear at Usiel but he dodges it.

"You missed." He laughed.

"Did I?" You make you hand into a fist, and the spear shatters into tiny shards of Ice, and they fly back towards Usiel, impaling him in multiple spots. Usiel falls out of the air and smashes into the ground.

"Here you take him." Zephon tosses Issei to Izrail. "Take him and leave. I'll deal with the Leviathan."

"Normally I wouldn't agree to this, but I've had enough of this guy." Izrail flys through the roof.

"I've waited centuries to fight a descendant, of the original Leviathan." Zephon, takes his robe off and it crashes to the ground. "This should be a good fight." The large black haired fallen angel cracks his knuckles before cracking his neck. "I'll be taking you back with us."

"You'll have to kill me first." Ice forms on Zephons wings causing him to drop to the floor. "But I'll kill you long before that happens." Ice soon spreads from the floor on to his legs and it travels up his body exposing itself on his arms and face. His skin turns a pale blue, and he almost completely stops moving.

"You're power is quiet deceptiv..." Zephon stops speaking as his eyes gain a glassy look to them.

"What just happened?" Rias asked.

"His body temperature dropped to absolute zero." Sona bluntly stated. "He froze him on a sub atomic level. every atom in his body is frozen solid."

"You little bastard!" Usiel stands up, and creates a sword of purple light. "I'll personally make sure you die!" He charges at you, but you holds out your left hand and a magic circle forms. In a matter of mere moments Usiel is covered in a thin blue ice.

"I hate Fallen Angels." You kick Usiel in his head, and it goes flying into a wall and shatters.

You drop to your knee as your head pounds. "Damn... it." You wings retract, and you eye turns back to it's normal color. "I still can't maintain that power for long."

"I believe you're missing something." Someone with a cocky tone said. You all turn to Shiori, holding Issei, and Kioko standing next to her.

"Good job you tw..." you try to stand up, but you collapse, and everything thing goes black.

"W-where am I?" You sit up, and look around.

"Good to see you're awake."

"Rias? Where am I?"

"You're in the occult research club room, I had Asia heal you." Rias sits on the edge of the bed. "You suffered a lot of damage for someone that only got hit a few times."

"It was my power, ever since I got injured, My body can't withstand my full power for very long."

"Oh." She stands up and walks to the edge of the room. "I brought you here to help heal you, but I also have some busy to discuss with you." She turns back towards you. "My brother and I have arranged for Shiori and Kioko to receive protection from the Gremory family, but in exchange you join me as one of my servants."

You think for a moment. "Deal, I can't protect them forever, and now that the Fallen Angels know I possess Dimension Lost, I could use the protection from them. So which piece will I be?"

"Bishop would be the perfect piece, but I already have two so I'll make you a rook, it will help with your defense." Rias makes you her rook, and she introduces you to the rest of her servants. "I'll go inform my brother of your decision."
