Pre-Prologue

"Hi there, stranger!" Byleth looks up at the familiar voice. The fighting instructor of the Officer's Academy leans against the gate. "Long time no see!"

Byleth smiles, stopping in place and spreading out his arms. "Come greet your big brother!"

To the students' shock, their strictest teacher runs from the gate and then flying tackles him. Many eyes widen when she laughs as he spins her around.

"I'm older," the female twin mutters as he sets her on the ground. Their hug is a desperate, familiar thing reminding them they aren't alone. They separate with a wide grin and eyes too sharp. Then she stops ignoring the others, greeting everyone who's come with Byleth.

At least she knows what's coming, he thinks, watching with a fond smile as her emotions are placed behind the cool mask she carries from last life. We'll get through this.

What he gets from his last life is the ease to make friends. With his sister laying the groundwork all these years, it's no wonder he's going to be offered to teach.

He is the most approachable twin, after all.
