Multiverse: Starting with Mushoku Tensei

Roah opened his attribute panel, and the transparent display read:

[Character: Roah Greyrat]

[Age: 2]

[Strength: G]

[Agility: G]

[Stamina: G]

[Intelligence: D]

[Talents: Immaculate Soul (Stage One), Fool (Stage One), Greed]

[Skills: Intermediate Magic Knowledge, Swordsmanship (Untrained)]

[Evaluation: You possess exceptional potential for growth, but for now, apart from magic, you're utterly useless.]

He tapped on the "World Capture" section. A small line of text appeared:

[Temporal Power: 50/100 (World capture unavailable)]

The key feature of the system was the World Capture function. According to the system's description, it would split off a fragment of his soul and send it to another world as a "stowaway."

In that world, by completing tasks or significantly altering the worldline, the system would extract the world's essence to replenish itself. Success would unlock access to new worlds.

For the Main God's pawns, this process provided points and exchange permissions.

For Roah, however, it meant he could recover the soul fragment and choose specific abilities from his alternate self in that world.

He didn't know the finer details yet, as he hadn't activated his first World Capture.

Temporal Power increased naturally over time but at a painfully slow rate. After two years, it had barely reached 50 out of 100.

In this world, magic included healing magic, offensive magic, and summoning magic. It was ranked into Beginner, Intermediate, Advanced, Saint, King, Emperor, and God levels.

Magic could be cast via chanting or magic circles. Higher levels granted titles like "Saint Mage" or "Emperor Mage."

The three dominant swordsmanship schools were the Sword God Style, Water God Style, and North God Style. Each school's founder was honored with the title of "god."

Like magic, swordsmanship was ranked into seven levels: Beginner, Intermediate, Advanced, Saint, King, Emperor, and God.

Roah's magical talent was extraordinary, but he was limited to intermediate-level spells due to the lack of advanced learning materials.

'Magic is a fascinating concept,' he thought. 'It's incredibly versatile.'

By channeling mana within the body and performing specific chants, mana could be transformed into various types of power. It could manifest as elemental forces like wind, fire, water, or earth—or as holy light for healing.

Mana was the foundation of all magic, akin to an engine driving a car.

Roah's talent was monstrous, to the point that even the word "prodigy" seemed insufficient.

At two months old, he learned to walk. By four months, he was speaking simple sentences. By six months, he was reading magic books on his own, much to Lilia's astonishment and Paul and Zenith's delight.

In short, Roah possessed an unbelievably high aptitude for learning.

However, his doll-like face was perpetually emotionless.

It wasn't that Roah lacked emotions; in fact, his inner thoughts were quite lively. But his face always displayed a calm indifference.

Even when he was happy, his smile twisted into what looked like a cold smirk, leading Paul and Zenith to think they had upset him somehow.

Only after spending more time with him did they realize this was just his way of expressing joy.

---

Despite his maturity and independence, Paul and Zenith never doubted their son's abilities. Instead, they basked in pride over his talents.

Roah, in turn, avoided troubling them and focused on his mana training.

The process was simple: cast spells, exhaust his mana, and gradually increase his mana pool.

Roah's mana capacity was unusually large. Even as a beginner, it took several intermediate-level spells to deplete his reserves.

As his capacity grew, intermediate spells were no longer sufficient for training, prompting him to experiment with new techniques.

Currently, he was developing something he called the "Magic Sword."

---

'Each person's mana has unique properties,' Roah thought. 'And these properties affect how mana is used for casting spells.'

Through experimentation, he discovered that his mana was not only dense but also unusually malleable and destructive.

Typically, mana served as fuel for casting spells. However, Roah's mana could manifest physically, retaining its destructive properties even without being converted into a spell.

This made his mana highly versatile but also incredibly energy-intensive.

The Magic Sword was a technique he developed to capitalize on these properties.

With a flick of his wrist, a pitch-black dagger materialized in his pale hand.

The dagger, composed entirely of his black mana, bore intricate patterns along its surface and radiated an overwhelming aura of destruction.

By this world's standards, the Magic Sword's fully realized form could rival King-tier spells in power.

Most advanced spells required long preparation times and specific conditions, with instant casting only possible for lower-tier magic. Even prodigies like Rudeus couldn't bypass these constraints for higher-level magic.

But the Magic Sword was different.

It was instant.

As long as his mana held out, it could theoretically obliterate an entire town in a single moment.

Roah twirled the dagger, its dark glow reflecting in his golden eyes. After an hour of practice, his mana reserves were finally depleted.

Thanks to his immense mental fortitude, he didn't faint. Instead, he let out a lazy yawn, feeling slightly drained.

He sighed and walked toward the door.

In the living room, Lilia was diligently cleaning. Her graceful figure moved efficiently as she carried out her tasks.

Paul, ever the doting husband, had been spending all his time with Zenith. Judging by Zenith's condition, it was clear she was expecting another child soon.

Roah observed silently. The large house felt emptier with Paul and Zenith so preoccupied, leaving Lilia to handle the chores on her own.
