On the rooftop of an abandoned building in Kuoh Town. There, the Gremory Peerage surrounds a hunched figure. An aging Stray Devil, with a disgusting smirk stretched across his face.
"Yuuto!"
Rias' voice is sharp, commanding.
"Yes, President!"
Kiba dashes forward, blade gleaming under the moonlight. With a precise slash, the Stray drops to his knees, defeated.
A breath later, Akeno, Koneko, and Asia ascend the staircase behind them.
"Oh my, it's already over?" Akeno smiles, teasing.
"Akeno-san, Koneko-chan."
"We're finished too. Well done, everyone." Rias says. Kiba keeps his sword aimed at the devil's throat.
"This one was really weak." Koneko mutters and tosses down a strange looking insect. It hisses and melts into goo.
"That thing was his familiar? Gross." Issei makes a face.
"It came after my breasts for some reason." Akeno ponders aloud.
"...Your breasts?" Rias raises an eyebrow.
"An Issei-senpai-like insect," Koneko says deadpan.
"Hey! Quit comparing things to me!" Issei groans.
"Everyone..." Asia stumbles up behind them, flushed and panting.
"Are you okay, Asia?" Issei asks.
"Y-Yes... Akeno-san and Koneko-chan protected me..."
Rias steps forward, arms crossed, standing over the defeated devil.
"Stray. This is checkmate. Unless... you'd rather die here."
"No, I surrender," the Stray grumbles. "As expected I'm no match for the daughter of the Gremory family."
His eyes drop. "Nice tits."
{Ryusei's House}
In her bedroom, Ryusei is doing one-handed pushups with Charcadet watching from the dresser.
She suddenly stops.
"...I feel an overwhelming urge to murder someone. But I don't know why." She stares into space, mildly confused. Charcadet tilts his head.
{Back to the rooftop}
Issei lunges forward, face red. "Hey! You don't talk to the President like that!"
"An Issei-senpai-like devil," Koneko mutters again.
"Seriously, what is it with you all and these comparisons?!"
"Akeno," Rias says coolly. "Restrain him. Send him to Hell."
"Gladly," Akeno purrs. "It's more fun for me if you resist." She raises her hand and binds the stray in glowing light. A crimson teleportation circle glows beneath him.
"Let Hell decide your fate." Rias declares.
The Stray chuckles darkly.
"I only did what was needed to be done." And he vanishes.
Issei watches, still confused.
"What the hell did that mean?"
Rias brushes dust off her skirt.
"Well, I'll see you all tomorrow."
"Where are you going?" Issei asks.
"To visit Ryusei. I'm meeting her sister tonight."
"Wait, why? It's not like you two are together."
Rias only smirks.
"Oh... we are."
"Wait, WHAT? Also-what happened to Riser? I was out cold for a whole week and no one's explained anything!"
"I'll tell you tomorrow, Issei." Rias turns, walking off.
{Later- at Ryusei's house}
Rias and Ryusei sit on the couch, whispering. Ryusei blushes as Rias gently presses against her, lips brushing softly.
The front door opens. Haruka Okkotsu, Ryusei's older sister, steps in wearing scrubs, clearly just home from a hospital shift.
She freezes in the doorway.
Rias is lying on top of Ryusei, and Ryusei is clearly mid-kiss, wide-eyed in shock.
"...I'm home?" Haruka says slowly, blinking.
"H-Haruka!" Ryusei stammers, quickly pushing Rias off. "I-I can explain-!"
Haruka walks in, setting her bag down with a deep sigh.
"...So my little sister has a girlfriend now."
Rias stands up gracefully, smoothing her skirt and bowing politely.
"It's an honor to meet you, Haruka-san. I'm Rias Gremory."
The scene shifts to the kitchen, where Haruka and Rias stand side by side at the stove. Haruka, having tied her hair into a quick ponytail, stirs a sizzling pan of vegetables while glancing sideways at her guest. Rias, donned in an apron Ryusei lent her, is chopping onions with surprising grace.
The sound of oil popping fills the kitchen-alongside a growing sense of tension.
At the dining table, Ryusei slouches in her chair, face in her hands, mortified.
"So..." Haruka starts, "You and Ryusei."
Rias offers a small smile. "Yes."
"You like her?"
"Very much."
Haruka raises an eyebrow. "And you're not just playing around?"
"I would never." Rias replies smoothly. "I care about Ryusei deeply. I respect her strength, her heart... and her loyalty."
Haruka hums. "You're very poetic."
"I mean every word."
Haruka turns off the heat and leans on the counter, arms folded. "Listen, Rias. Ryusei might seem like the 'tough girl' type, but she has had it rough the past few years. She's not the type who opens up easily. So if you're going to be in her life... be serious about it."
Rias nods sincerely. "I am. I don't take this lightly. I want to be someone Ryusei can rely on."
At the table, Ryusei lets out a muffled groan into her hands.
"I can hear you both, you know..."
Haruka smirks.
"Good. Then maybe you'll think twice before making out on the couch where your big sister can walk in."
"Haruka!!"
The three sit down together.
"Alright, let's eat before I ask about your grades, curfews, and whether you've had the talk yet." Haruka teases.
"I am going to evaporate into pure energy and never return."
"You know," Haruka said as she stretched, a sly smile tugging at her lips, "if you're too tired to head back tonight, Rias, you're welcome to stay over."
Rias blinked in surprise, then smiled warmly. "I'd love to, actually. If it's alright with you."
"Of course," Haruka replied as she leaned against the doorframe. "You're practically family now, right?"
Ryusei choked on her own breath. "Wait, what-?"
But Haruka wasn't finished. She stepped closer with a twinkle in her violet eyes. "And if you're staying the night... maybe I can show you some of Ryusei's baby pictures while we're up late."
Rias's entire face lit up like a child on Christmas morning. "Oh? I'd love to see those."
"No!" Ryusei sat up so fast the pillow on her lap tumbled to the floor. "Anything but that, please!"
Haruka gave a faux-innocent tilt of her head. "Why not? You were such a cute baby. Especially in that duck onesie with the little webbed feet. Remember that one, Ryu-chan?"
"Haruka, I swear to god-!" Ryusei sputtered, horrified.
"Oh, now I definitely have to see it," Rias giggled, clearly reveling in her girlfriend's embarrassment.
"It's settled then," Haruka said with mock formality. "I'll bring them out in the morning."
With a groan of defeat, Ryusei collapsed backward into the couch cushions, burying her face in one.
Rias leaned in, brushing a strand of Ryusei's hair behind her ear before placing a soft kiss on her cheek. "It's okay," she whispered playfully. "I love every side of you-even the duck onesie version."
From somewhere beneath the pillow, Ryusei's voice emerged, muffled and despairing. "I'm never going to live this down..."
