Highschool DxD: An Old Friend

Koneko x Male Reader

====================

A young man sat at the edge of a large building, he stares at the busy city below his feet, he cracks his fingers as he did. "Another boring night." He tells himself as he blows a piece (H,C) hair off his face, his cloudy (E,C) eyes showing boredom. "Greetings (Y,N)." He sighs before he turns his head to a tall, elegant male that looks older than him, he pushes himself up before he steps in front of the man. "Hello again Sirzech." The older male smiles as he puts his hand the boy's shoulder, he squeezed it lightly before bringing him in for a hug. "Ah, its so good to see you again (Y,N), how long has it been?" The young male pulls back and gives the king of hell an unamused look, a small smile forms on his face before he answers. "I don't remember, I've been hit on the head too many times now, I think its messing up my memory." Sirzech shakes his head as he chuckles, a magic circle appears under feet, which teleports them to hell, to the office of the devil, in the home of the Gremory's. "Its good to be back here." (Y,N) says as he looks at the familiar surroundings, Sirzech nods as he takes a seat on his desk. "I did bring you here for a reason." The boy turns to him and nods before he sits in front of his old friend. "What for?" Sirzech smiles as he looks into the boy's eyes. "I need you to train an old friend, Koneko Toujou."

====================

"Can't believe I agreed to this." (Y,N) tells himself as he stands in front of door, he shakes his head before he knocks on it. "Oh well, at least I get to see old friends." The opens, revealing a blonde haired priestess, Asia, she smiles. "Hello, how may I help you?" She asked, (Y,N) knew about the harem, he had to read on the Great Red Dragon Emperor in order to know who he will soon meet. "Hello, I'm (Y,N) Nightclaw, I believe Sirzech sent me himself." Her eyes wide before she let him in, she tells him to tale a seat while she gets Rias. "Comfy." He comments as he waits, looking around until he is sent to a wall, he gets up and holds his cheek before turning to the culprit, the yokai herself. "Good to see you again Koneko." The white haired yokai glares at him as she holds her fist in front of her body, he bares his fangs. "Why are you here (Y,N)!?" She asks harshly, suddenly a dark aura fills the room. "What is going on here!?" The crimson haired devil, Rias steps between the two and glares at the both of them. "She attacked me." He says as she turns to Koneko. "You deserved it, don't act innocent." She comments as she lowers her guard, the Red Dragon Emperor himself walks besides her along with Asia. "Who is this guy?"

"My name is (Y,N) Nightclaw, Sirzech sent me here to help Koneko control her powers." He says as he holds an icepack to his cheek, Issei just stares at him while Koneko is looking away eating, Rias stands up. "I see my brother finally got the message, even though Koneko has been training with her sister, I believe its a good idea to train with an old enemy." Issei gets up and looks at (Y,N), he just looks right back as he crushes the ice pack. "Enemy?" He asks, Koneko stops eating and gets up, she walks out the door, slamming it so hard that it falls off it's hinges. "I'll g-." Rias stops Issei as (Y,N) follows Koneko, she gives him a reassuring smile. "Let those two work it out, how about we take a bath?" She asks, he smiles and follows her, but still worried for his friend.

====================

Koneko stood in an open field, she just looks at a tree with a few claw marks on if, (Y,N) watches her and sighs before she begins to talk. "Why did you let yourself go?" She asks, taking the breath of out him, he looks at the ground before he speaks. "I wanted the power to protect you and Kuroka, after you two became strays, I knew she would probably get you two killed." He says as electricity surges through his body, making his hair stand up, giving him a spiky hair style. "You didn't have to do that, you hurt us more than you helped, I didn't want to believe that my best friend sold himself for power, just like my sister." She says as tears slowly fell off her cheeks, he steps closer and turns her head towards him, he wipes the tears off her face. "I'm sorry Koneko, I just didn't want you two to get hurt, but I did." He says as he looks into her golden eyes, she pulls away before she hugs him tightly. "Don't ever sacrifice yourself for power, you and Kuroka already did it once, I don't want it to happen again." He nods and smiles, hugging his old friend back, but something inside wanted more.

====================

Its been five months, Koneko trains with (Y,N) near the Occult Research Club, he smiles as he blocks most of her attacks. "Give up?" He asks with a smirk, she shakes her head before she begins to punch him more, he rolls his eyes and jumps back. "That's enough for now." He says as Issei and Rias walk up to them, (Y,N) watches as Koneko hugs Issei and smiles, he frowns a little. Rias smiles at both of her servants, he walks off, deciding to clear his mind after training. He walks down a small path, he stops when he sees the tree, he stops in front it and a blink of an eye it came crashing down, shaking the ground. "(Y,N)?" Koneko walks up to him and looks at the tree, he turns to her and gives her a fake smile. "Just wanted to get rid of old memories." He says as he looks sown at his old friend, she gives him a small smile. "Okay, why did you walk off?" He looks down and sighs. "I just has to think about something and now I'm sure." He says before he grabs the nekomata by her shoulders and pulls her into kiss, she tense up for a bit before she kisses her best friend back. "I told you he loved her." Asia tells Issei as they spy on the new couple. "You were right, but I will pummel him if he hurts her." Rias giggles before she hugs Issei. "Well I doubt he'll ever do that, but its nice that you're defensive." (Y,N) lifts Koneko up and carries her back to the old building of the Occult Research Club, she giggles as she held onto her boyfriend. "What now (Y,N)?" She asks as he smiles a little. "Training, but not in combat."
