I was exposed as the strongest magician to my sister, who has severe brother complex. I can no longer hide my abilities at school!

Chapter 1 : Alvin’s Sister!

That evening, Alvin was fidgeting alone at home.

Unlike his older sister, Cecil, Alvin hadn’t yet attended the academy. Despite his age, he should have started this year. Though he’d love to throw a tantrum, crying out that he didn’t want to go, he couldn’t burden his family by not attending due to their position as one of the prominent Duke’s family.

If he had gone that far, then his family would be facing trouble with the Duke’s reputation being tarnished, and causing more embarrassment would make life even harder for the family in high society and among the nobility.

However, Alvin wasn’t shameless enough to go that far.

…..However, that’s a digression.

‘Now, what should I say when nee-san comes back…’

His sister was like a walking rumor mill. He has to do something or things could get out of hand. He couldn’t allow his years of concealed struggles to crumble in a single moment.

So, somehow… Alvin needed to make Cecil misunderstand.

‘…Well, it’s probably not going to happen that quickly.’

Surely, when she returns, she’ll immediately say, “What’s with that ability!?”

Alvin simulated his response in his head while nervously pacing in front of the entrance. Finally, with a creaking sound, the front door opened.

“Ah, welcome back, nee-san—”

What emerged from there was his sister, whose eyes swollen from crying.

“Hic… I’m home, Al-kun…:”

“What happened?”

This entrance was certainly unexpected for him.

“Everyone said…”

Cecil was usually a sun-like girl who was annoyingly bright and was always smiling. And now, the same bright and cheerful girl was in tears. Alvin couldn’t help but worry about what had happened.

“I told them so many times, but they didn’t believe that Al-kun is strong!”

That worry he initially had vanished in just three seconds when he heard her words.

“Well, yeah. If suddenly someone, who is known for being disgraceful, says, ‘Actually, I’m strong,’ normal people won’t believe it easily.”

“Hic… I said it during the whole-school assembly…”

“What the heck?!”

Alvin had underestimated the walking rumor mill. He never thought she would take such a drastic action. This only made him more reluctant to go to the academy.

“It’s fine, nee-san? You’re having a crucial misunderstanding.”

Alvin looked into Cecil’s eyes with a serious gaze, holding her shoulders, expressing his feelings clearly. Whether it got through or not, Cecil wiped away her tears and smiled.

“Yeah, I understand… Al-kun.”

“As expected of nee-san…”

“Don’t underestimate your onee-san. We’ve spent a lot of time together, Al-kun.”

He understood. Alvin felt a sense of relief and happiness as he realized his feelings had been conveyed.

“Nee-san…”

Alvin may have misunderstood a little —

“The wedding ceremony is supposed to be after your coming of age, right?”

— That his sister was a little crazy.

“No, nee-san. That’s not what I meant.”

“Is that si!? Did Al-kun really say something like getting married to big sis?”

“That’s not what I meant.”

“You said it twice!?”

— In truth, this is the true nature Cecil Astarea. She has a severe brother complex.

Since childhood, she has admired her younger brother, showering him with excessive affection. Despite being an excellent catch with good looks, skills, and no issues with the family succession, she remained unmarried till this date, because she earnestly declared, “I’m going to marry my brother!”

Because of this, those around her have come to know about Cecil’s intense brother complex, and considering they aren’t even blood-related, is seen as somewhat problematic.

However, for now, such matters are irrelevant.

“I’m not as strong as you think, nee-san. You know what people say about me, right?”

“A cool and cute, wonderful young man—”

“I’m called an incompetent disgrace to the Duke’s family.”

Interrupting Cecil’s words, Alvin continued speaking.

“At that time, I just happened to get lost in that cave, and the bandits were already collapsed when I reached there. Also, because I thought that my life was in danger, I just happened to deflect your sword.”

“Is that so…?”

“That’s how it is. So—”

—Clank!

At the moment he said those words, Cecil swung the sword she had at Alvin’s neck with all her might.

The speed was unbelievable as if she was a master swordsman. However, Alvin deflected the sword heading towards him with an ice pillar he created from the ground just in time.

“Please believe me nee-san.”

“There’s no element of belief left.”

Cecil gave a sidelong glance to Alvin, who brushed off his sword and said those words with a straight face as if it was a casual thing to do.

Even so, Cecil has the strength to lead the Academy’s knight order with just her physical strength.

Given that Alvin didn’t even pay attention to the sword aimed at him with the intention of killing, there was indeed some exaggeration in his statement.

“It’s different, nee-san! What you just saw was just a coincidence… Yes, it is a coincidence!”

“It’s amazing how a pillar of ice was created by chance as well.”

“Darn it! A sister who points a sword at her brother is the worst… Haah!”

The servants around were looking at us and talking about something.

By the time we realized, it was already too late… After all, Alvin, who was thought to be incompetent could use magic without an incantation.

“Tomorrow, you will accompany your big sis to the academy and make everyone believe in me.”

“Leave my peaceful life alone Nee-san…!!”

A cheerful smile appeared on his sister’s face, and Alvin’s scream in horror beside her.
