The Greatest (The Beginning After The End X Male Reader)

Little sister

The time has come... What is it, you ask? My little sister, Eleanor, will be born today. Even though my memory of the comic is vague now, I remember that Arthur has a little sister named Eleanor, and she will be mine and Arthur's little sister.

Despite the fact that I was reborn and am living my life as Alexander Leywin, I don't feel like I deserve this life. Maybe I'm overthinking, but am I supposed to exist? I know there are many alternate universes out there, but I just don't get it.

I am waiting outside of the room. My mood is a bit of a mess. I never thought of having a little sister, but now I'm going to be a big brother. Even though Art is supposed to be my big brother, he never really acts like one in the first place... maybe because we are adults in mind.

"Sigh... I need to stop overthinking." I close my eyes, trying to relax my mind.

Finally, I heard a creaking sound as I opened my eyes. The door opened, revealing Dad and the baby on his arm. His smile is warm as he looks at the baby.

"Alex, from now on, this is your little sister, Eleanor Leywin." Dad gave me the baby Eleanor. I stare at the baby.

"Hello~ I'm your big brother." I whisper softly as I caress her.

Her little hand suddenly grab my finger and laughed. Dad gently smiled as he watches us. I smile as I continue holding baby Eleanor.

Although I'm busy training I'll make sure to make time for Eleanor. At least, I'll fill the place that Art couldn't do in Eleanor's early life.

Training has been daily life for me but my body needs a lot of development and rest. Being healthy is more important than forcing my body to train and break.

After training, I always take care of Ellie when mom can't. She's adorable and it's urged me to hug her everytime, she's the cutest little sister ever.

And without notice, my personality has changed. I can express my emotions easily with my family which I'm really happy about and with Ellie, she easily melts my serious demeanor.

Anything for my little sister, I would do it. After all, it was a big brother's job.

...

"The training today is over. You could rest now." "Master said."

As always, the master quickly left without any more words. Leaving me alone on the ground, I jolted up and went back to the manor.

I enter Ellie's room and am greeted by mom, holding baby Ellie. Mom smiled as she saw me finish my training and asked, "Alex, how's the training today?"

"Just like usual, training my wind magic and water magic." After I said that, I held out my hands to hug little Ellie, but Mom pushed me away from Ellie.

"You are sweaty, young mister. Go take a bath." Mom sternly said,

"Buttt Ellie recover my stamina! I swear it'll be quick." I pouted.

"No is no. Now go take a bath and clean yourself up from the sweats. " Mom warned me.

"Alright..." I let out a sigh of defeat.

Big Time Skip (3 Years)

Three years have passed, and my routine every day is training and babysitting Ellie. I've been progressing at a quick pace. I am now a light orange core mage.

Only my family and master knew (including the Helstea family). They were in disbelief when they saw how fast I was progressing, but my master assured them that it was my talent and nothing dangerous would happen to me.
