As a girl who had stepped into the realm of the extraordinary through the sword, Saeko Busujima naturally possessed physical strength far beyond that of ordinary people. Yet every time they trained in the kendo hall, she would be gasping for breath while Kuzeha still looked like nothing had happened. Now, though the battlefield had changed, Saeko still felt a bit weak.
And as she expected...
Under Kuzeha's series of advanced techniques, Saeko soon found herself unable to keep up. She hadn't expected this to be even more exhausting than sword practice! Earlier, she had even thought that if it got too late, Kuzeha could just stay for dinner—but now, she couldn't even last until then!
Her soul was still exploring, but her body had already given up. If Kuzeha hadn't held back, she probably would've passed out already.
"Saeko-senpai, just rest well for now," Kuzeha said gently, pinching her cheeks that were flushed with pink.
"You're calling me senpai now..." Saeko lifted her beautiful eyes, her expression lazily seductive. "Half an hour ago, who was the one yelling that again?"
Kuzeha looked at her with a half-smile. Seeing her slightly embarrassed expression, he chuckled softly. "Mm, then in front of others, I'll call you Saeko. In private, I'll call you senpai. That better expresses our... unique relationship. No reason to act all close in public and distant in private, right? Wouldn't that just mean you're using your senpai title to buff your attack speed?"
Saeko rolled her eyes at him playfully, though she was clearly too drained to put much force into it.
Kuzeha didn't stay at her place much longer. Once she fell asleep, he quietly left.
Meanwhile, in Sora's room—
A double bed leaned against the wall, pure white sheets topped with a neat row of black-and-white rabbit plushies. On the nearby table sat a massive TV, a game console, and a stack of game cases.
Two stunningly beautiful girls were sitting at the desk, seriously discussing strategy.
"When Yuu comes back, we'll take turns—one hour each!"
"I'll have him play a brand-new little-sister galgame first, and after that, you show him some little-sister anime!"
Sora's face was grave as she spoke to Akiko Himenokoji.
Just moments ago, they had received the latest intel on Yuki...
Well, it wasn't exactly secret intel—it was a message Yuki openly posted in the group chat: she'd be spending the night here!
The news instantly sent Sora and Akiko into high alert. This was their first real challenge after forming an alliance. Whether they could suppress the final boss Yuki or not depended on this first battle!
To avoid repeating their previous mistake, Sora had selected a galgame that included both biological and stepsister routes. The most crucial point: in this game, the blood-related sister's route was filled with resistance from family, friends, and society, ultimately leading to a tragic separation. In contrast, the stepsister's route was showered with blessings, and she and the brother lived happily ever after.
It had taken a lot of effort to find a game with such a stark contrast!
"Yuki, exposing your real little sister identity was your biggest mistake!"
This time, Sora wouldn't repeat her failure!
But Akiko frowned slightly. "No way. You live with him. You get way more time with our dear Onii-sama. Today, I go first!"
Sora bit her lip but eventually nodded in compromise. To keep the alliance intact against Yuki, she would hold back—for now. After all, starting Monday, Akiko had to go back to school. Then, Yuu would be hers again.
Akiko's anime was similar to Sora's game—one where the stepsister ends up happily with her brother. Tonight, their plan was to work together and brainwash Kuzeha with the concept: "Stepsisters are the best!"
Just then, they heard Ayumi yell, "Onii-chan's back!" and their spirits soared.
"I'm going first!" Akiko leapt up, the words "Bro X Sis" printed on her T-shirt clearly visible. She and Sora exchanged a glance—both their eyes burned with determination.
"Good luck!"
Akiko rushed to Yu's side.
"Onii-sama! Come to my room! I want to show you a really good anime!" she said, tugging at his sleeve.
Unexpectedly, Ayumi and Kanao also latched onto his shirt and followed.
"Why are you two coming too?" Akiko asked, confused.
"Aren't we watching a fun anime? I wanna watch too!" Ayumi tilted her head innocently. Kanao nodded as well.
Akiko panicked.
Then Ayumi suddenly looked at her suspiciously. "Wait… is this one of those... not-for-kids anime?"
Akiko's expression shifted. She glanced at Kuzeha, quickly clarifying, "N-no! Nothing inappropriate!"
If she were really planning to show something NSFW, she'd sneak into Yuu's room in the middle of the night. Make a little noise "by accident," and let him catch her... Boom—perfect setup!
She giggled to herself at the fantasy. But no—she'd only dare imagine it. If she could actually pull it off, she wouldn't fear Yuki at all!
"Fine, if you wanna watch, come along."
"Yay!"
The two younger girls cheered. Akiko frowned. Not an ideal start... But they were the least threatening of the sisters. Their feelings toward Yuu were still pure, innocent. Surely they wouldn't understand... right?
The four of them gathered in Akiko's room. It wasn't large, with a bed, wardrobe, TV, and a single large cushion on the floor. Big enough for two. Three at most. But four?
Akiko popped the anime BD into the player. When she turned around, Ayumi and Kanao were already snuggled up on either side of Kuzeha.
Narrowing her eyes, she quickly laid down beside him, half-resting in his lap. Three girls in a triangle—Kuzeha in the middle.
Kuzeha didn't mind. He was used to having little lolis clinging to him since he was a kid.
The Blu-ray loaded, and the anime began.
Kuzeha's lip twitched. This was an anime adaptation of his own light novel. A top-tier incest drama modeled after several classics from his past life. It had shattered sales records upon release. Even after the anime aired last year, BD and merch sales kept skyrocketing—earning him a fortune.
He still carried the nickname "The True God of Incest."
Of course Akiko would pick this for tonight's agenda. He should've guessed. Especially with Ayumi and Kanao here too...
He glanced at the two girls, both fully focused on the screen. "Hopefully Akiko won't influence them too much…"
Three episodes in an hour—just enough to lay out the plot. And during the OP and ED, Akiko kept passionately explaining the siblings' emotional journey, hoping to drive the point home.
As the original author, Kuzeha remained unfazed. But Kanao and Ayumi listened intently. Ayumi even pulled out a notebook.
"So... stepsisters do all this for their brother?" she muttered, jotting down notes.
Akiko's mood turned complicated. She felt like she had just trained two rivals with her own hands…
"But aside from Yuki, the others aren't a big threat…"
An hour passed.
Sora, who had been waiting, finally opened the door.
Seeing Ayumi and Kanao there surprised her. She and Akiko exchanged a glance before Sora cut straight to the chase. "Yuu, come play games with me!"
Ayumi and Kanao weren't that into games. Sora successfully pulled Kuzeha away.
The game was already at the galgame main menu. Kuzeha didn't need to ask—he got the message. No wonder she hadn't barged in earlier—they'd planned the schedule together.
Halfway through, Kuzeha noticed the game's theme had changed—it was now a stepsister route...
"These two girls really are staying on high alert for Yuki…"
He chuckled to himself.
Yuki should be arriving tonight. And just as he thought of her, her familiar voice rang out from the living room.
"Yo, Akiko! Long time no see!"
"Where's my dear bro? Don't tell me you've already snatched him up?"
"Oh, I see—he's in Sora's room!"
"Wait, it's not your time yet...!"
Yuki's voice was followed by quick footsteps.
The doorknob turned.
Locked.
Yuki raised an eyebrow. "Locked?"
Inside, Sora smirked slightly. She'd learned her lesson last time and wasn't going to repeat it.
Outside, Akiko mentally gave Sora a thumbs-up. Truly worthy of her long-time rivalry with Yuki—even anticipated this.
But then, Yuki pulled out a key from her pocket and click—opened the door.
Akiko's jaw dropped.
Yuki twirled the key, smiling. "Did you forget? I'm the one who changed this lock, remember?"
She strolled up behind Kuzeha, leaned in over his shoulder, and looked at the screen. Then turned to Sora.
"Switched to stepsister now?"
Sora bit her lip but stood firm.
"Stepsisters are number one!"
Akiko stood beside her. Together, they raised the flag of "Stepsisters Forever!"
"That's right!"
"They're the true path!"
Yuki blinked, amused by the show of unity. She chuckled like a queen.
"Do you two even understand how rare real little sisters are?"
She stepped forward, speaking with conviction.
"Real sisters are the forbidden love born from the ultimate combination of brother, sister, brocon, siscon—it's rare across the entire world!"
"True incest is one of the rarest, most precious bonds in existence!"
"Stepsisters? They're just a degraded copy!"
"You say stepsisters are number one?"
"Well, then real sisters are the sky above them!"
Her words rattled Akiko and Sora. Their confidence wavered. After hearing Yuki's passionate speech, they couldn't help but feel like... she had a point.
"Think it over."
With that, she turned back.
"Oh, and bro worked hard today judging. A thoughtful little sister knows how to help her brother relax at night~"
Seeing the shaken expressions on the two girls, Yuki's scheming eyes glinted. She nodded, satisfied.
Round one of the Akiko-Sora alliance: complete defeat.
Late at night.
Yuki quietly stepped out of her room.
She glanced at Akiko and Sora's rooms—completely silent.
"They're really being obedient?"
Even she was surprised.
With light footsteps, she approached Kuzeha's door.
"Too bad... looks like tonight, this disobedient little sister will have to do it herself."
