[Explosive Advantage] Engaging in a Mental Battle with the Strongest Evil Spirit Since Birth, I Exceeded the Measurable Magic Limit – The Humble Conquest of the Cursed Child - Chapter 13

“Kai! Happy fifth birthday!”

Surrounded by a birthday cake, his father and mother smiled warmly.

Kai had turned five years old.

It had already been a year since he began training with Miss Kagami, and despite his young age, his body had become rather well-toned.

Concerned that this might stunt his growth, Kai had once asked Kagami if building muscle at such a young age could affect his height.

Kagami explained that the idea of childhood strength training stunting growth lacked scientific evidence. Furthermore, she added that for an exorcist, being short was not a disadvantage—in fact, having a smaller target and greater agility could be advantageous.

After hearing this, Kai thought, “Yeah… guys like Me* or Riva** are short but crazy strong…”* and was satisfied.

(Still… I’m five now…)

Being five meant he only had one year left until the age of six—when his parents had died in his previous life.

To be precise, his birthday was April 3rd, and his parents had passed away around April 14th.

(I don’t know if something like fate convergence really exists… but if I’ve got just over a year, I need to approach training with real focus…)

Kai quietly reaffirmed his determination.

Just then—

“Kai! Here’s your birthday present, the one you wanted!”

Unaware of his son’s solemn thoughts, Kai’s father cheerfully held out a bag.

“Woooow! Thank youuu!”

Kai responded with deliberately childish excitement.

“Still, I’m relieved. I thought you might ask for something weird, but wanting a Wii U is nice and normal for a kid.”

“Hehe…”

Kai gave a bashful smile outwardly while smirking inwardly.

(With this… I can finally browse freely.)

That’s right—the Wii U had a web browser.

Kai’s true aim was to use it to research magic-related topics on his own.
Honestly, he would’ve preferred a laptop or tablet, but those were too much for a five-year-old’s birthday. Even a game console was pushing it, but because he never usually asked for such things, it worked in his favor.

(Man… It’s 2015, so no Switch yet…)

As he mused over such trivial matters—

“Hey! What is this marvelous contraption?! Let me try it, boy!”

(…Someone’s a little too excited. Let’s just ignore him.)

Then—

“Fuh… fuhnyaaah! Fuhnyaaah!”

The other person in their mother’s arms, who had been sleeping peacefully, suddenly woke up.

“Oh my, Meguri, do you want to celebrate your big brother’s birthday too?”

Their mother smiled gently as she spoke.

Yes—this was Meguri, Kai’s little sister, who would soon turn one.

Looking at her, Kai thought—

(My little sister… You’re still… adorable, aren’t you…)

There was a reason for that still.
In his past life, the two of them hadn’t been particularly close.

Kai knew Meguri would grow into a beautiful woman, just like their mother.

However, her nickname for him in their previous life had been: “Loser Brother Crap.”

That was what she’d called him.

(At least call me Crap Loser Brother… That way, brother is still the main part, but “Loser Brother Crap” puts the crap first…)

Reflecting on his sad former life, Kai gently stroked Meguri’s cheek.

“There, there…”

“Fuhnya…”

Meguri stopped crying and looked at him curiously.

“Kai…! You’re so kind!”

“Kai, you’re gonna be super popular with girls one day!”

His parents praised him exaggeratedly. Watching them, Kai thought—

(…After we lost Dad and Mom, we were both immature, and I was pretty harsh with her in the past life…)

He regretted the estranged relationship he’d had with his sister.

That’s why—

(In this life, I’ll be as kind as I possibly can…)

He made that resolution.

However… sibling quarrels are more or less normal.

“That’s it! Kai and Meguri should just get married! Hahaha!”

(…What is this man saying…?)

Kai gave his father a cold, deadpan stare.

“Oh my, Papa’s getting ahead of himself, isn’t he~?”

Their mother smiled serenely as she spoke.

Kai would soon come to realize that his parents’ comments weren’t entirely jokes.

In this world, aside from the existence of spirit demons (reima), there were a few other… unusual differences as well.

“Fuhnyaaah…”

Unaware of all this, Meguri yawned contentedly.
