Rias Gremory was showing her Peerage a picture of the house where the stray Devil named Viser was hiding. Something was going to happen, she could feel it in the prickling of her skin, but she didn't know what. The Devil wasn't particularly high ranked, it was just a low level devil that had gotten arrogant.
Before anything could happen, a teleportation circle appeared in the middle of the Occult Research Club headquarters, the seal of Beelzebub glowing before it flared and revealed a blond, bearded man with his hair in a ponytail wearing a black suit and tie, a white and gold sword at his hip. Instantly, Yuuto was out of the chair he was sitting in and lunging forward at top speed. The man just tilted his head, dodging the strike, reached up to grab the sword with his hand, and snapped it like a twig.
"Nice try, Yuuto," the man chuckled, tossing the broken sword fragment behind him, "but I'm a couple centuries too old for such an obvious attack! You're doing alright, then?"
"Yes, Jaune-Sensei," Yuuto bowed at the waist, only to blink as Jaune pulled him into a light hug.
"Good to hear, kiddo," the man said, before turning to Rias and giving a half bow, "Princess Gremory."
"Jaune Arc," she said, smiling at him, "What do I own the pleasure?"
"Who's the old guy?" Issei asked, drawing Jaune's gaze.
"You got a new… pawn, I assume?" He said, "Jaune Arc, I helped train Yuuto in swordsmanship. Anyways, sorry to drop in so suddenly, Rias, but I need a favor."
"What can I do for you, Arc-san?" She said.
"The stray Devil in your territory? I think my King is going after it."
"Ruby is in my territory, and nobody told me?"
"As I said, I think she is. She tends to only tell Ajuka and Blake where she's going and they don't really care enough to tell us normally. I just happened to be dropping by when she was on a call with him and she mentioned Viser. Do you mind if I come with you to deal with her, that way if Ruby is there, I can talk to her?"
"No, of course I don't mind," Rias said, "It shouldn't be a hard fight either way, but it'd be nice to have another High Class Devil there just in case."
— X Ruby X—
Ruby whistled to herself as she climbed off Wilted Rose and began walking through the houses under construction in Kuoh Town, spinning the sheathed form of Floating Array around with one hand. Finally, in the middle of the neighborhood, she drew the recreation of her friend's sword from its sheath and let it split into ten blades, the last one staying in her hand while the other nine were carried by devilish magic into the buildings around her.
A faint smile crossed the huntress's lips as she felt one of the swords be smacked to the ground and pinned there, quivering under the weight of her prey. Ruby didn't so much pick up the pace as disintegrate, reforming in front of the house in several flowing lines of rose petals. The other swords flew to the same location, forming into a pair of wings missing a pinon at her back. With her free hand, Ruby drew Crescent Rose off her back and unfolded it, one handing the hulking scythe. Kicking open the door, she walked into it to confront the devil in question.
She was, at a glance and half hidden in shadow, a beautiful young woman, though that part was easily mistaken among Devils. Ruby herself had been in her physical twenties since becoming Ajuka's Queen a little under six hundred years ago, and it wasn't unheard of for Devil parents to look like their children, or even grandchildren's, older siblings. When your lives were measured in the thousands of years, you tended to age gracefully.
Anyways, away from that tangential thought, the beautiful young woman had short white hair and voluminous breasts… but any attractiveness of her appearance was killed by the chimerical centaurian lower half of her body. A furred, mouthed gut leered at her, red clawed feet gripped onto the missing blade of Floating Array, and a snapping, snake headed tail.
The grin, both of them, died as she realized who she was staring at, "Ruby Rose."
"Viser, right?" Ruby chirped, before her face grew serious, "That is who you are, right?"
"W-why are you here?" She said, swallowing
"Stray Devil's going around eating people," Ruby answered, "Not only does it make us look bad, it's begging for the human world to find out about us. So-"
Ruby dodged the strike from Viser's spear with a simple sidestep. A one handed twirl of Crescent Rose split the spear in two, swinging the scythe to rest on her shoulder.
"It's my job to take you out," Ruby said, and the blades of Floating Array changed as she pushed her Special Technique, Silver Eyed Warrior, through them. They blazed with the same silver light as her eyes, making a burning combination of halo and wing behind her back as the blade beneath Viser's foot lit up too. The Stray Devil lept back with a yelp, the foot that had held Floating Array having turned to stone. The blade picked up off the ground and joined its siblings in making her fake wings, "I could understand you going Stray. I wouldn't even mind it, really, I wouldn't. But the fact that you've started eating humans… that's over the line for me."
"What was I supposed to eat?" Viser snapped, firing two trails of acid from magical circles over her breasts. Ruby disintegrated around them, reforming once the sprays were done and shifting Crescent Rose into rifle form so she could aim it at Viser.
"Literally anything else," Ruby said, followed by the sound like a car backfiring and the anti-material rifle petrifying Viser and then blowing the statue to pieces. Yawning, she deactivated Silver Eyed Warrior and returned both Crescent Rose and Floating Array to their sheaths. Walking out of the house, she blinked once before a wide grin split her face.
"Hey, Jaune!"
— X Issei X—
Issei watched the woman step out of the house, her entire body except for her lower face covered by a red cloak. There was a heartbeat before a wide grin split that lower half and she began to walk forwards, spreading her arms as she went and revealing a black leather riding jacket and a red skirt with black leggings, "Hey Jaune!"
She hugged the taller man, who hugged her right back before pulling away and beginning to look her over, "You're alright, right? You haven't gotten hurt since the last time we saw you?"
"Jaune, I'm fine," the woman batted down her hood, revealing a pretty woman a few years older than Issei, red tinted black hair cut in a spiky bob and strange gray eyes glimmering in the moonlight as she did, "I ran into a couple of exorcists down in Recife, but I talked them down. Oh, you brought little Rias and her Peerage"
The woman immediately broke from her hug with Arc to run up to the President, pulling her into a hug that Rias happily returned, "Look at you, you've gotten so big!"
"That tends to happen when you get older, Rose-san," Rias joked, only to break from her behavior as Rose tweaked her nose, yelping cutely.
"Come on, Rias, none of that "Rose-san" nonsense. I've known you since you were a baby."
"Please don't play with my nose like that," Rias blushed, "I'm almost a full grown woman."
"You'll always be little Rias to me," Rose said, before turning towards Akeno and offering her a hug. The black haired devil smiled and stepped into the slightly taller woman's embrace.
"Yuuto," she said, "I know you aren't one for touching people you don't know that well. Is it alright if I give you a hug?"
Kiba nodded, and was pulled into a hug in turn. Finally, she broke from the hug and turned to Issei, "Hello! I don't think we've met?"
"Uh, no. I've only been a Devil for a couple of days," Issei said, swallowing as the weird grey eyes looked him over, "I'm Hyoudou Issei."
After a moment, a smile blossomed on her face and she pulled Issei into a hug, her chest pressing against his and causing his brain to malfunction for a second. Holy crap, he was being hugged by a woman!
The hug broke quicker than Issei would have liked, and she swept around to face Jaune, "So what are you doing here, Jaune?"
"Looking for you," Jaune said, "We need you back in Akihabara. I'm not sure if Ajuka told you-"
"-the newest version of the portal will be ready soon? Yeah, he did, I was gonna head to Akihabara right after this."
"You live in Akihabara?" Issei said, the Otaku Holyland?
"We're in charge of it like Rias is in charge of Kuoh," Ruby said, "actually, if you want, you could come along for a bit? I'm sure Sona can pull some strings if you're out of school."
"She doesn't like doing that," Rias pointed out.
"But she will if Sera and I ask her to," Jaune said.
"Please, Buchou?" Issei pled.
"Oh, fine. A day won't hurt anyone, I'll mark it as an extra curricular club activity," Rias sighed.
