Demon King Evolution History

And my favorite sister didn't know where to go.

Kotori's mouth formed a へ shape in boredom, rattling on the swing.

"Uuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuu..."

Tears fell drop by drop, Kotori wiped her eyes with her sleeve.

Kotori often cries at every turn, which is what is often called a crybaby.

I was reminded by my sister just this morning, maybe I will be hated by my sister if I go on like this.

No... Maybe my sister doesn't like Kotori anymore, that's why I didn't go home today...

Now, what are you crying about?

Such a voice came from above Kotori's head.

"Eh……?"

Kiri raised her head.

An indescribable figure was standing there.

Obviously knowing where the other party is, but can't tell what kind of appearance it is.

He could clearly recognize the words, but he didn't know what kind of voice it was.

Such a person is there.

Kotori's shoulders trembled.

Even if he had been warned not to talk to strangers, it was hard not to be wary of such unknown characters.

"No, it's okay... my sister has almost gone back..."

Saying so, Kotori wiped her eyes, jumped off the swing, and walked towards home.

But

snort!My father, mother, and sister are not here, so it's my birthday, but I'm so lonely!

Hearing this, Kotori couldn't help but stop.

"W-why? This kind of thing..."

A certain person did not answer this, and continued to speak calmly.

As long as you become stronger than now, you will be able to gain sister's approval!

"……that is……"

nah!Want to get stronger?Let my sister no longer have to worry about her own strength, don't you want it?

Kotori fell silent, feeling that someone laughed softly.

Then, she stretched out her hand towards Kotori.

On the palm, something like a small ruby ​​appeared, emitting a dim light, a very mysterious object.

"so beautiful……"

Someone smiled again at this, and continued.

If, if you want to become stronger, you should get in touch with this.In this way, you will become stronger than anyone else.Your sister will definitely like you who have become stronger.

Kotori swallowed hard.

"Really...can Oni-chan...like me?"

ah, of course

Kotori slowly stretched out her hand to 'touch' that...

This touch is bad.

In an instant, the red gemstone melted into Kotori's palm, and his whole body felt hot like a fire.

At the same time, Kotori's clothes burned and transformed into something like a wonderful kimono.

"...Ah, ah..."

Kotori's expression was distorted by the hot pain that hit her whole body.

But things didn't end there.

There was a red flame around Kotori

"Ahhhhhhhhhhhhhhhhhhhhhhhhhhh"

As Kotori shouted, the flames spread around.

To the park, to the home there, to the apartment next to it, to the store further to the other side.

Violently, violently, as if trying to swallow up the entire town where Kotori was.

At that moment, a flash of light poured down from the sky onto the ground, and the person in front of Kotori disappeared.

However, the current Kotori has no spare time to take care of it.
