Fern (Frieren)

This story is based on a fictional charachter, there will be a chapter for every episode from the anime. In this story Fern isn't a child, she has 18 years old and Heiter didn't died when she was 13, but 5 years later.

Fern is now a beautiful lady, happy to be finally an adult in the human society. She is even higher than her new master and teacher: Frieren.
"okay Mistress Frieren, we are ready to depart"
Frieren's face is passionless like always, maybe a little bit bored.
"What are you talking about? You are clearly not ready, where is your diaper?"
Frieren's word confuse our young hero, that think her master is joking.
"My diaper? I don't hav- I don't use those things"
"But you have and will, so? Where are them?"
Fern is now even more confused, why is she having this conversation?
"Mistress Frieren what are you talking about?"
"Now that you are my disciple, I'm gonna treat you like my master treated me"
Fern can't believe to her hears
"But, I don't know in wich situation you and your master were, but we don't even have diapers here"
"Okay then we will stop to the near village before depart to get everything we need. And thank me, at least I'm not letting you go around wearing "only" the diaper like my teacher used to do with me. I know you human have modesty, so it's enough if you wear those under your skirt. Well, shall we be off?"

After Frieren words, Fern is a little bit shocked, can this be just a big prank? Maybe mistress Frieren just want and excuse to take a look at the town before we start our voyage.

The two girls stroll trough the city market
"Here"
Fern look down, worried
"C'mon Fern, tell him what we need"
In front of Fern there is a young boy, he has more or less her same age, he is cute, lean and with some freckles on the face.
"W- We need-"
Fern couldn't say it, all she sould think about was "Why?"
Why am I doing this?
Why I have to do it?
Why can't there be another girl to ask for diapers instead of her?
"Fern, here another rule, there will be consequences when you disobey me"
But the boy spoke
"If you are here, then I suppose you are looking for some diapers for your little brother"
"YES! My little brother, that's right"
"Perfect, then I suggest these, my own father produce them, the best in the city"
Frieren interrupted the conversation
"No, those are too small and there is no brother, we need diaper for her, do yuu have something?"
"What?" The boy was confused for a moment, took another look to the human girl that looks like she is gonna start to cry now.
"Please Mistress Frieren, can't we just start our jourey and stop with this story? Isn't this enough?"
While Fern's voice was shaking, Frieren's voice was calm, and confident
"No, we will take those, I can see them from here, they should be big enough for you"
Frieren pointed at some pink diapers decorated with a lot of hearts all around. Instead the guy laughed a bit.
"Luckily there's a bench right here, just lie down while I put your diaper on"
"Mistress Frieren wait. Maybe you didn't realized it, but I'm 18, I'm not a little girl anymore. I don't need diapers. Mistress Frieren, let's stop this madness and forget about it. What happened it's already a trauma for me"
"Fern, there will be consequences if you not obey, please lie down and behave.
Fern feel chained like she couldn't move, escape from this crazy situation. She eyes soaked eyes like if it is a miracle she didn't start to cry already, the voice is shaking like never before
"At least can we do it somewhere else. Mistress Frieren, I never spoke to a guy especially my age, I always lived with father Heiiter and you in the wood, I don't want to remember my first experience as me asking him for diapers and then wear them in front of him"
Frieren maked a faced excessively bored
"Okay, but if you piss yourself before we camp tonight, I'm gonna make you walk in just a diaper for a full month"
Fern didn't knew how to react, if being thankful or angry for the way she is being treated, but her gentle and educate soul took control.
"Thank you Mistress Frieren, I won't disappoint you"
Frieren paid the guy, while Fern didn't had the guts to look at him in the eyes and both left quickly.
