The self-cultivation of the passer-by hero

"Fran?! Why are you here?"

Remilia was shocked. She was not shocked why her sister would appear here, but she was surprised that the other party's attitude seemed to be to stand against her.

This is a story about a certain 495-year-old young vampire.

Her thick blond hair is tied into a slightly curly side ponytail, and she wears a pink hat on her head. She has red eyes, a dark red miniskirt, and weird wings with colorful crystals hanging from her back.

Her name is Flandre, Flandre Scarlet.

That's right, she is the owner of the Scarlet Devil Mansion - Remilia Scarlet's younger sister.

The Scarlet Devil Mansion has just moved to Gensokyo. However, whether in the outside world or in Gensokyo, even if everyone knows that the owner of the Scarlet Devil Mansion is a powerful vampire lord, they will never know that she has a sister.

Not to mention that this younger sister has never shown her figure in front of people.

In fact, to be more accurate, it should be that the second lady of the Scarlet Devil Mansion was never allowed to appear in front of people.

All the residents of the Scarlet Devil Mansion have a common understanding of her, that is——

"She is still a child, and it is not easy to control her emotions. Although she is very well-behaved at times, it is difficult for others to understand her."

Flandre usually lives in the basement of the Scarlet Devil Mansion, which is deeper than Patchouli's big library.

For the second lady of the Scarlet Devil Mansion, who was of the same mental age and appearance, she couldn't understand why the attitudes of the people around her were so cruel to her.

The maid Sakuya always brought food to herself respectfully, and then left without saying a word.

Although doorman Meiling often plays with her, whenever she asks to go out, the other party always refuses with a wry smile.

Her friend Patchouli always had a cold face towards her. Although she never treated her harshly, whenever she tried to "escape" forcefully, the other party would always use magic to stop her.

Finally, there is her sister, Remilia.

The elder sister's attitude towards her is very strange. Everything the other party does in memory seems to be for one purpose, that is to alienate her.

She was locked in the deepest basement of the Scarlet Devil Mansion, and she was not allowed to go out. Although she would visit her occasionally, she left immediately.

Flandre was still just a child, so she naturally didn't know what a prisoner was, but now she really felt the feeling of being imprisoned.

No one can understand her, no one is willing to play with her. Every day, Flandre wakes up from a human world and can only remain silent in front of the toys piled in the room.

The long-term loneliness has made her forget the concept of time. She can't remember how long she has been here, and she doesn't know how long she will stay here.

The spiral of contradictions pricked Flandre's young heart, until this day, a stranger appeared in her world.

"Huh? What, it turns out to be a child. I thought I finally found the mastermind of the mutation, Da☆Ze."

She has golden hair similar to her own, but not as gloomy as her own. The other person always seems to maintain a sparkling attitude.

That's great.

Inexplicably, looking at the strange blonde girl, Flandre felt envious.

But soon, she started fighting with this strange sister whom she had a crush on.

Yes, that's right, fighting.

Although Flandre wanted to understand what the longing in her heart was, she still preferred having someone to play with her.

It had been too long since happiness had appeared in her world.

She immediately launched an attack on her strange sister. Although the other party was a little panicked at first, she quickly reacted. Unlike the people who had alienated her in the past, she actually showed a cheerful smile.

"Damage game? Interesting Da☆Ze!"

While this strange sister was dodging her attacks, she started to counterattack with gorgeous magic. At the same time, she asked herself without hesitation——

"Hey kid, my name is Marisa Kirisame, and I am a magician. What about you?"

".Flandreau."

How long has it been since anyone asked you your name?

It’s been so long that I can’t even remember.

Suddenly, something deep in Flandre's heart seemed to be touched. She suddenly smiled, revealing a smile that was crazier and more dangerous than ordinary children, but more in line with her true heart.

"My name is Flandre, Flandre Scarlet!"

Wielding Levatin, Flandre's weapon, a giant sword made entirely of flames, she acted unscrupulously on her own instincts.

Destroying everything in front of him, and truly enjoying it.

She chased Marisa, breaking the bedroom door along the way, breaking the barrier in the basement, and even breaking the barrier set by Patchouli in the library.

Never felt like this.

As if they had a tacit understanding, Flandre and Marisa were immersed in the battle called "Damaku Game" regardless of everything, even if there were gravel and sawdust flying around them every moment, they didn't care.

Most of Marisa's magics are of the light and heat type. Although they are gorgeous, they seem to be slightly less destructive. Flandre's attacks just make up for this. Her attacks are very powerful.

One of them forgot that they were here to solve the mutation, and the other forgot that this was their home. They showed the art of fighting to the fullest.

Until she appeared——

"No wonder it's so noisy, Fran, it's you."

"Patch."

The sudden appearance of her friend woke Flandre out of her world of interest. She looked at the indifferent Patchouli with some fear, not knowing what to say for a moment.

"Remi is doing something very important now, so don't cause us any trouble."

Trouble, it seems to have always been like this.

Flandre's eyes dropped.

As expected, Patchouli raised her hand and a water column hit her. Flandre, who no longer wanted to resist, was easily comforted in a water ball.

Water is a vampire's weakness, and Patchouli used this method to stop herself every time.

The excitement in her eyes was no longer the same, and all that was left in her dim pupils was loss and powerlessness. Patchouli's magic was like a cage, sealing herself in a lightless world, with no hope and no way to escape.

However, Flandre never thought that the so-called cage could be broken.

"Hey, magician, is this red mist caused by you?"

Without fear, the human magician Marisa, who seemed a little immature to Flandre, actually stood in front of Patchouli.

"It seems like an unknown rat has slipped in."

Staring at Marisa coldly, the magic book in Patchouli's hand began to glow with a strange light, and the destroyed magic circles in the library began to reappear at a speed visible to the naked eye, as if going back in time.

"Hey, are you a magician too? Just right! Let's use magic to show off Da☆Ze!"

Marisa took out the Bagua furnace-like prop. At first glance, she knew how ridiculous it was compared to the power of Patchouli Noreki, the magician who studied orthodox magic - Nanaya.

"Hehe, hahahaha——"

It was a mocking laugh. Even Patchouli did not hide her contempt for Marisa. In other words, it was precisely because it was Patchouli that she felt disdain.

"It's interesting. A kid who has studied magic for several years actually dares to say such things in front of me."

As soon as he finished speaking, the number of magic circles around him instantly increased several times, and the library was already surrounded by densely packed magics that were ready to go out.

The expression on Marisa's face finally changed. Patchouli raised her hand, and the surrounding light instantly became more dazzling.

"At least before you become undead, let me see what real magic is like. It can also be a good conversation piece after you arrive in the underworld."

"Hey, don't underestimate me! Magician!"

Without hesitation, Marisa rode her broom and rushed forward to face the countless magics. The Bagua furnace in her hand emitted a weak but still dazzling light.

At that moment, Flandre saw something different in the other person's appearance, which seemed to have nothing to do with the strength of the power itself, but something beyond that.

""Master Spark" (Extreme Spark)! "
