Summary
Consumed by grief over Dimitri’s miserable end at Gronder Field, Byleth musters the last of her power to go back in time to his childhood and prevent the tragedies that befall him all throughout his life.
Unbeknownst to her, Dimitri still has a darkness innate to him—only this time, he’s hell-bent on making his beloved tutor Byleth his and his alone.

Summary

To her surprise, Byleth is pleasant, and Dimitri starts to see her as the mother she never had. The idea of Byleth being family soon becomes appealing.
Until it all goes awry when Dimitri’s affections twist into something perverse.

Summary
There were two versions of Dimitri—the boy and the man. The boy was dead, so she buried him in a box in her mind—to a place she’d forget, hopefully. She and the man wed, they were happy, and all was well.
But unbeknownst to her, the boy doesn’t stay buried for long.

Summary
After a tragic accident shatters Byleth’s dreams of greener pastures, she wakes up from a seven-year coma to find Dimitri, her foster brother, waiting for her.
Dimitri is the perfect caretaker. He’s sweet and patient, always tending to her every need with devotion and an unwavering smile. So when a quiet unease stirs within her—when his touch lingers, when his kindness feels a little too perfect—Byleth ignores it.
He just misses her. That’s all.

Summary
The Azure Moon Project was the Faerghus Aerospace Corps’ plan to terraform the moon until it could house human life indefinitely.
This project was handled by the Blue Lion Terraforming Corps: a group of eight highly skilled astronauts, all under the guidance of their Chief Officer. The astronauts were divided into two groups, each one taking a six month shift of active duty. While one group was on active duty on the moon, the other gave them support from back in Fhirdiad.
While on duty on the moon, Dimitri realized that perhaps his grasp on reality was slipping.

Summary
The year of our Lord is 1476.
As a slave lucky enough to be bought by an alchemist under the full influence of the Renaissance, your curiosity was encouraged, fostered. With his death, ripped away. Your next buyer is a decrepit drunkard, recent widower, and father of three. He takes your first kiss—so you knee him in the balls, and dash outside in nothing but your nightdress. He tackles you to the ground; his beard scratches your closed eyes, closed mouth; his blood soaks through to your skin.
Above you a creature of the night has his limp flesh on a long claw, crimson spilling from its gnawing teeth. Without hesitating you spring to your feet, and run right into the woods towards a dark castle with two human corpses impaled outside.
You never look back.

Summary
“I see. Well, an heir is important for a kingdom,” the older woman says, her tone rising slightly on the trite response, like she were suddenly addressing a child. It's the tone she might use to address her own. Crossing her arms over her chest, shaking her head, a furrow coming to her meticulously plucked brow. “Have you considered a surrogate?”
“What?” The short, sharp word is out before she realises that she has spoken. Byleth forces her jaw to halt and seize to stop her teeth from grinding.

Summary
She leans in towards him, and, with no sign of agitation—or any hint, really, of what she is about to broach—she asks him, “What payment do you seek from me? My blade is yours already, so I do not understand what it is you want from me. Unless it is my body you want to have?"
For a moment, Dimitri cannot understand what she has just said to him. He has never heard her joke. Nor has he ever heard her say something so—incomprehensible. Then, seeing his utter confusion, she gestures from her breasts, to her groin, to the pale length of her thighs. Her skin is visible through the pattern of her tights. It looks so tender, he can only imagine how soft, how warm—

(Or, Dimitri wants to share a meal with Byleth, and Byleth has been taught there is no such thing as a free meal.)
