Level 1 Strongest Sage ~

“Haru-nii, they only have ten months in this world, right?”

Akari asked one day.

“Yup, that’s right.”

There are only 300 days in a year in this world.

By the way, each year has ten months, each month 30 days.

There are five weeks in a month, and 6 days in a week.

It took me a while to master the dating system in this world.

“I see… So they don’t have that.”

Akari looked depressed.

“That?”

“..Christmas.”

Ahh, I see her point.

They don’t have December here, so of course they don’t have Christmas.

Even if they did have December, it’s kinda hard to imagine the custom (?) of old, white-bearded Santa Claus clad in red robes breaking into houses in the middle of the night and leaving presents under the children’s pillows spreading throughout this world.

It’s already a given that only the bandits and robbers would have the nerve to break into houses in the middle of the night.

If they noticed anyone other than the family members sneaking into the house in the middle of the night, that sneaky person would immediately become a target of attacks.

There are also homes that have traps that will be automatically activated if someone other than family is detected.

Aristocratic mansions, in particular, are often equipped with traps that are powerful enough to annihilate monsters and other non-people entities if the installations detected that they possessed mana and magic.

“Then, there shouldn’t be Santa-san here too?”

Akari also believed in Santa back when we were in our previous world.

However, this is the Otherworld, the Isekai.

She must be thinking that if they have Christmas here, then there must be a genuine Santa.

However, this world only had 10 months.

“...Yup.”

If there is a December, a Christmas and a Santa Claus and he’ll go around giving gifts in this world, then that Santa must be someone very powerful or else he won’t be fit for the job.

It’s extremely important that he could evade all the traps laid out.

He must also be gallantly strong enough that he could go toe-to-toe with the family head who would surely attack to protect his family.

Else, he must possess excellent spy skills so that he could detect the traps that even people couldn’t.

I can’t help but think that a burglar has the higher probability of having those skills.

“I-I see…”

Santa doesn’t exist in this world.

Akari became really gloomy once she realized that truth.

It was then that I remembered something.

“Akari. They don’t have Christmas, but they do have something like Santa here.”

“Eh!?”

“Legend says that there’s an Old Man called ‘Gifter’ in this world, and he gives presents to children on their birthdays.”

It is said that only the children who were good throughout the year got gifts.

They get another present in addition to the birthday gift their parents give them.

Children from poor parents whose parents can’t afford to give gifts may also receive presents from the Gifter if they are good.

“Akari’s birthday… if we go by our previous world’s dating system, then it’s next week, right?”

“Y-Yup! Haru-nii, you remember.”

“Of course.”

It’s only natural that I remember the birthday of my cute little sister.

When I transmigrated into this world, my birthday changed.

My birthday was in November in my previous world, after all.

The goddess of the other world created a body

In this world, Akari had transmigrated into a body created by the goddess of the other world, so she didn’t know when her exact birthday was, apparently. And so, we decided to celebrate her birthday according to the date from our previous world.

“Akari helped me defeat Evil God, and you’re also doing your best with the chores. You’ll probably get a gift from the Gifter, I think. You’re gonna get presents from us too, of course.”

Whenever somebody celebrates their birthday in the Ernol family, I prepare a gift according to whatever she wishes.

“Really!?”

“Yeah. By the way, if the Gifter comes by, what do you want from him?”

“Well, hmm…”

Akari blushed.

It must be something difficult to tell me.

“The Gifter will definitely see if a child is good or not. He also knows what that child wants, apparently. That’s why if it’s hard for you to say, you don’t have to tell me.”

“So that’s how it is!”

Akari seemed relieved.

Afterward, Akari told me that she would tell me what she wanted for her birthday from me on the day itself.

It’s something I can prepare on that day, apparently.

Akari probably won’t be too unreasonable with her request, so there shouldn’t be any problems.

By the way, that “Gifter” story is just a legend.

That’s why, as unfortunate as it might sound, a genuine Gifter won’t come on Akari’s birthday.

But then, my sister really looks forward to getting a gift from Santa (?).

I’m going to grant that wish.

“Alright, let’s do this!”

She didn’t tell me anything, but I already knew.

I’m going to evade all the countless traps laid out within the mansion.

I’ll place her gift under her pillow without none the wiser.

An existence surpassing even the best stalker and robbers —

This Isekai Santa will be me!!
