2 years old.

{Part 1}

2 years old...

At this time, he finally realized the existence of Mana. With Zenith performing Healing Magic, he wasn't an idiot not to realize it. That the reason he was able to walk in his own two feet despite being a newborn baby, was because of the mysterious energy called Mana.

And that Mana could be used to strengthen his body by wrapping it around his body and wear it like an invisible armor.

At first he only subconsciously use it, but with his tremendous talent he was able to master manipulating Mana.

"That's too easy." There is no sense of achievement when he finally got the hang of it.

This past two years, his routine would be mastering this Technique to augment his physical abilities along with his locomotor mechanical movements.

Two years passed and he finally could fully control his body and move it how he wanted.

With his relationships with his surroundings, it is okay.

Zenith was a doting mother. His relationship with her was the best amongst everyone. Reinhard liked being breastfed on her loving arms. Though he was very embarrassed being breastfed, there is nothing he could do about it.

Paul was the handsome cool guy of a father. He occasionally see him being flirty with Zenith. Reinhard is observing him practicing swordsmanship in the yard

Lilia was a capable maid and was good with cleaning. Reinhard liked her because she is very capable and reliable. Though he could sense that deep inside, Lilia feared him but didn't show it in her face. Not only him, but also his twin brother.

As for Rudeus? In his eyes he was nothing more than a creepy pervert. Out of all the people Reinhard met, he was the one who had the lowest affection points. He is just a side character in his eyes.

"Reinhard Greyrat."

Finally he could speak the language of this world very fluently. The language of this world was close to Japanese, so he was able to pick it up quickly enough.

The written characters were completely different, but the grammar was close to what he was familiar with, which thankfully meant he mostly needed to learn vocabulary, a good chunk of which he wasalready been exposed to. Paul would read to him along with Rudeus, which allowed him to readily pick up words.

Once he finally begun to read, he just needed to do some self studying to be proficient with the language. Using a stick and try writing it on the ground forming letters.

Whenever he is done with his everyday routine of physical exercises, he would study on his own.

"Lilia, is this right? My name?" Reinhard pointed at the dirt with a clumsily written letters that had the spelling of his name. Still with the way he talked is very cute being a 2 years old and all.

Lilia who is by his side doing some household chores complied. She looked at the letters arranged in the dirt and nodded, "Yes, that is correct. [Reinhard Greyrat]."

"Okay." Reinhard nods to himself and practiced writing even more letters and words.

{Part 3}

Lilia looked at Reinhard with a very strange eyes. Ever since a year ago, she was greatly impressed with both the Young Masters in the household.

A year ago the child that she was very repulsed with, Rudeus, started looking at the books in the study.

One day, Lilia took a quick peek and there he was, staring fixedly at a book and muttering to himself. What he was saying didn't sound like words. Not words from the common language on the Central Continent, at least. In recent days, she'd gotten a sense of earnestness and diligence from him that she was loath to interfere with.

As for the child he deeply feared the most, Reinhard, had sensed a prideful attitude. A newborn baby just the day after it was born can walk with it's own legs.

Lilia had once heard a story in the palace harem. Back when the Asuran prince was still a baby, he'd crawl all around the harem grounds, night after night. It turned out he was possessed by a demon. Not knowing this, one of the attendants picked him up, and he pulled out a knife he'd hidden being his back and killed her by stabbing her in the heart. It was a frightful story.

And Reinhard was just exactly that. Lilia had no doubts: This was another case of demonic possession. Oh, the boy was calm and placid now, but once the demon within him awoke, he'd make his way through the house while the family was asleep and kill them all one by one. Though she felt the same creepiness with Rudeus, but Reinhard had the qualification of physical ability to carry out such actions.

"He really grown so fast didn't he?" Madame Zenith doesn't seem to be worried or alarmed by the strangeness at all.

It was up to her to do something about it.

Lilia rushed to the store, spending a small sum on what she needed. Then, when the Greyrats were asleep, and without asking Paul for his permission, she performed a traditional charm of banishment from her homeland.

Thinking back on it now, she wondered if the charm worked. Or simply if the devils that possessed the twins got a change of heart? Or lastly nothing was really wrong in the first place.

Either way, nothing did really happen.

{Part 4}

Reinhard missed his previous life as a highschool student.

He is not like every person in a light novels or fanfictions that romanticized the 'isekai' genre.

Truthfully, if you give him a choice wether he should continue living in this world or go back to Earth. He would choose the latter.

"Nothing to do... So booored... I wanna play soccer and crush those trash... I want to eat pudding..." Out of boredom he would mumble these kind of things.

Finishing his daily routine of physical exercises and studying, he would just watch the scenery in the windows of his room.

There in the yard was a handsome young man in his early twenties doing some sword practice.

His pupils would follow those rapid movements swings and could perfectly see it in slow motion.

Even in his previous life, his Dynamic vision had always been strong. And it seems in this world, it got even stronger, he didn't even know why.

This was also the reason why he's so super talented in sports in his previous life. Being able to observe kinetic motion stronger than ordinary people made his training speed much faster. If it was a game, he had some kind of [Exp Boost].

"Swordsmanship, unlike Magic this kind of thing would be my style." Reinhard was thinking.

Reinhard played lots of games with this kinds of settings before. Warriors, thief, archers, mages, swordsman, assassin, paladin, etc...

If you let him choose his job class, he would not hesitate and pick anything that has to do with swords. After all the main actors in this games are heroes, and heroes–though somewhat clichéd, always wield holy swords.

As for the other job classes, for him those are just for side characters that joined the hero's party to slay the Demon King. There had never been heroes that weren't swordsmen, at least in the games and stories he knew.

"I have decided, I'll practice Swordsmanship. And I will shine and become a One True King."

But first he will build his strength, and wait for his body to grow suitable for strenuous training.

After all he's only 2 years old...

Well he isn't in a rush. Rushing will only hurt his body and suffer irrecoverable injuries. Unless there is some kind of strong Healing Magic.

He will take it slow and steady.
