The unbelievable commotion began one morning near the end of autumn.

The mornings are getting colder, and the plants and animals are getting ready for the long winter.

The area around the house where Allen and his friends live is also covered with fallen leaves.

In the midst of the silence, a light humming echoes in the living room of the house.

"Mmm-hmm-hmm...

"Huh?

Allen looks up from his newspaper and blinks.

He looked up from the newspaper and saw Charlotte sitting in front of him, buttering a loaf of bread and playing a song with a smile on her face.

The scene was so funny that he couldn't help but smile. As I folded the newspaper, I asked Charlotte a question.

What's the matter, Charlotte? You're in a very good mood today.

"Oh, I'm sorry, ......, was that too loud?

No way. I'd like to hear more.

I interrupted you because I wanted to know why.

I thought it would be unusual for you to be so happy. Did something good happen to you?

"Well, it's more like ...... I'm going to have something good happen soon. It's a personal thing.

"Oh, that's a new one.

As Charlotte replied with a sly smile, Goussetsu, who was having breakfast right next to the table, looked up from his food dish.

He can turn into a human, but in normal times he is always dressed like this. It is said that his shoulders are stiff in that way.

He strokes his chin with a round paw and tilts his head.

You are going to play with Miaha and Eruca? If so, I will escort you.

No, sir. It's just a personal thing. ......

"What's that? When you're happy, Lu is happy.

"Hmm. Thank you, Lu.

Charlotte strokes Lu's head as she puts her chin on her lap.

Charlotte stroked Lu's head, and Allen and Gousset's eyes widened at the heartwarming sight.

I'm sure you'll be happy to know that the flowers in the garden are about to bloom and the birds are about to leave the nest. ......

Happiness is happiness, even if it is small.

I would not have been able to savor such happiness in the way I lived until early spring this year.

It is because of this that Allen feels warmth in his heart when Charlotte looks happy.

However, the ...... heartwarming atmosphere disappeared in an instant.

Charlotte put her palms together and said.

"Actually, I ...... have a birthday tomorrow. I'm turning eighteen.

Dogobichabareeeee!

Allen flipped over backwards in his chair, and Gousset slumped over and plunged his face into the food dish.

Silence reigned in the living room for a while.

Lu rolled her eyes and nodded her head.

'What's wrong, you two. What's wrong?

"Are you okay, Mr. Allen? I'm sure you'll be happy to hear that.

Charlotte ......, is that true ......?

Charlotte rushed over to Allen, who was lying on the floor.

Allen grabbed her hand tightly.

The blood drained from his face and his whole body was trembling badly. Still, he squeezed out a faint voice.

"Are you sure ...... tomorrow is your birthday?

"Yes, it is. Yes, but ......?

Charlotte's eyes went black and white, but she nodded firmly.

It's a good idea to have a good idea of what you're looking for.

Then Lu walks over and pulls on Charlotte's sleeve.

"Hey mom. What's the day of birth?

It's the day you were born. Don't you know, Lu?

"Well, Lu and Fenrir live a long time, you know. Maybe they don't care about the calendar too much.

While the two were chatting heartwarmingly, Goussetsu got up staggeringly.

With a piece of apple stuck to his face, Gousset squeezed out the same shaky voice as Allen.

It is true that demons like us are not familiar with this culture, but I remember that ...... humans used to celebrate birthdays. Is this a now defunct custom, by any chance? ......?

No, it is. It's still in use and celebrated with great fanfare.

"Is that so?

Charlotte just nodded her head as Allen assured her emphatically.

In some parts of the world, everyone rejoices on the first day of the new year.

However, in this country and in Charlotte's hometown, it was common practice to celebrate birthdays in a rather big way.

Gifts are given and small parties are held. When Allen was in his parents' house, he was also celebrated in an exaggerated way every time.

But Charlotte didn't seem to be getting the idea.

When I lived with my mother, we celebrated. ...... Aren't these things only for small children or special people? Natalia, your father and mother-in-law had big parties for their birthdays.

"You went by the name of the duke's daughter, didn't you ......? Didn't you have a party or something to show off to the rest of the family? ......

I've never been to a ...... party. ............ Oh!

Charlotte pondered for a while and then made a face of realization.

It's always a great time of year to have a big party at the mansion. But every year I'm told to stay in my room because I have a cold,......, and that's what I'm doing,......?

"So that's what ...... is.

Allen can only cover his face and nod.

(Probably because he was annoyed with celebrating his concubine's daughter. ......)

(He probably didn't want to celebrate his concubine's daughter or something.

The shyness and lack of self-esteem that she had in the beginning improved considerably, and Charlotte became much more positive.

However, due to her long years of slavery, she is still unaware of the world.

Although I had seen glimpses of this side of her from time to time, this was indeed unexpected.

This is the first time I've ever seen such a thing.

It's also my fault for not asking until now. ...... I'm sorry, I'm really sorry. ......

I'm sure you're not the only one.

It's not too late to apologize, Allen. It's not too late, Mr. Allen, why don't you give it a shot? I'm willing to help you.

"No, wait. Let's just focus on the task at hand, shall we?

I'm sure you'll be able to figure out how to do it.

It's not a bad idea to go for a shot here, but right now every minute is too precious.

Slowly standing up, Allen shouted from the bottom of his stomach.

"Yes! I've got it, Charlotte!

"What? What?

Charlotte tilted her head in confusion.

He wanted to congratulate her for 18 years.

That's why Allen wanted to declare...

"Tomorrow I'm going to make your birthday a big deal...

"Hey, I'm here to visit you!

What the hell?

As soon as the door behind him opened, a mass of deadly energy jumped at him.
