Frederick Felix Leon was a child picked up by Frederick during a mission.
As a time traveler, Leon has always been careful to live in the iron and blood. After all... he knows what kind of camp the iron and blood is. There are basically... few normal people here.
Until the day when he became an adult at the age of 18, Leon asked Frederick, who raised him from a baby to an adult, his only wish for a coming-of-age ceremony.
"Frederick, my only birthday wish is to go out and see."
"Huh? What are you...saying?"
For the first time, the iron-blooded person in charge showed a confused and flustered expression. She had thought about many possibilities, including her own situation, but...
She didn't expect that her child would want to leave her.
"I said...I want to go out and have a look."
Leon thought it was Frederick who didn't hear what he was saying clearly, but after he repeated what he said a second time... he found that Frederick's eyes seemed a little bit wrong.
