A Shared Older Sister
Elmidgit, Gloucester, Cumberland, York, Exeter, Clarence, and Lancaster.
These seven ducal houses traced their lineages all the way back to the imperial family itself—prestigious bloodlines collectively known as the Seven Great Nobles.
Gail was the direct heir of the Gloucester Ducal House, and Estelle—illegitimate or not—was still the daughter of the Elmidgit Duke.
And the transfer student, Luna, was the daughter of the Lancaster Duke. She hailed from a super-elite noble house on par with—or even surpassing—Gail and Estelle.
That Luna Lancaster had just called Leon "brother."
Will and the other classmates erupted in murmurs. Even Estelle's eyes went wide.
"Are you... actually some noble house's secret bastard child or something?"
Felica Scarlet, the marquis's daughter and classmate, spun around from the seat right in front of him, glaring at Leon with her scarlet eyes. Up until now, she'd barely ever spoken to him.
After all, Felica had a strong sense of class hierarchy and looked down on commoners like Leon. The other girls in class feared his Absolute Command skill so much they wouldn't even sit near him.
Leon shrugged and answered Felica's question.
"No way. That girl and I aren't siblings."
His surname was Lancaster, sure—but his blood ties to the Lancaster Ducal House were distant at best. Four generations back, one of his ancestors had been part of the duke's family, but as a branch line, they'd long since lost their noble status.
His father was a renowned Guardian in his own right, but only a knighted commoner with a title granted for a single generation.
"Then why would the Lancaster Duke's daughter call you 'brother'?"
"Well, it's not like there's no reason."
The petite Luna bounced over to Leon with lively steps.
And just like that, she plopped down in the empty seat next to him. With an "ehe," she grinned, her silver hair swaying.
"Please take care of me, Onii-sama♪ Oh, right—I skipped grades to transfer in. Pretty amazing, huh!? Praise me, praise me!"
"That's impressive, yeah."
"No heart in it at all~! We both trained under Aria-neechan together, didn't we? You could be a little nicer~."
Luna giggled with a mischievous chuckle.
That's right. Leon and Luna had trained together under the genius Guardian Aria when they were kids.
The Lancaster main family had heard about their distant relative's adopted daughter and hired Aria as a tutor for their second daughter, Luna.
Of course, Aria had been busy, so she couldn't devote much time to it. And Luna had plenty of other tutors besides.
But Luna had idolized the beautiful genius Aria. "I wanna be just like Aria-neechan!" had been her catchphrase back then. Aria had doted on her sweetly in return.
Leon had visited the Lancaster Ducal House with Aria and trained alongside Luna under her guidance. Back then, Luna had been friendly toward him too.
As the little brother of the person she admired, at least. Luna never minded his Absolute Command skill and had always been a sweet girl.
Leon excelled at swordsmanship, so she'd sparkle those emerald eyes of hers and say, "Onii-chan Leon is so cool!"
Indeed, Luna had called him "brother" back then. They were distant relatives sharing the same surname, so she'd looked up to Aria and Leon like an older sister and brother.
If things had stayed that way, they might have ended up as close childhood friends—or even like real siblings—despite the class divide.
But then Aria and Leon were kidnapped by anti-empire terrorists, ending their connection. Aria went missing, and naturally, she couldn't continue as Luna's tutor.
Three years passed without Leon seeing Luna. The 14-year-old girl before him now had grown far more womanly.
Her breasts were large for her age, straining against her uniform blouse. Either the size was off, or it was deliberate—either way, a glimpse of cleavage peeked out.
Leon's gaze was inevitably drawn to that white valley. Luna noticed and covered it with both hands, her face flushing red.
"Onii-sama's such a perv...!"
She said it in her clear, carrying voice. The entire class turned to stare.
Leon's reputation could hardly get any worse. Then again, enslaving the class saint had probably tanked it as far as it could go.
Luna stood from her seat and deliberately leaned against Leon, pressing her breasts into his chest.
Leon stiffened. The innocent little Luna from back then overlapped with the girl now.
Suddenly, Luna lowered her voice right by his ear.
"Planning to turn me into a slave with that skill and rape me too?"
"N-no, nothing like that."
"But Onii-sama Leon raped our precious Aria-neechan, didn't you? Shoved your cock in her over and over, knocked her up as your sex slave—you're a total monster, right?"
Luna giggled softly, blowing sweet breath into his ear.
What was Luna's goal...?
If this has you hooked, excited for more, and looking forward to the naughty training of this cheeky self-proclaimed little sister—
