Guillaume — Character from ISEKAI The Otherworlder’s Heir

Guillaume

Born in the Stratocracy of Algonis, Guillaume grew up in a world where a man’s worth was measured by the weight of his sword. Victories were celebrated. Hesitation was despised.

He had neither taste for discipline nor patience for obedience.

From an early age, he developed a different weapon.

Observe.

Understand.

Exploit.

The tavern air was thick with alcohol, exhaustion, and poorly concealed pride. Every evening, the same faces returned—soldiers on leave, overconfident adventurers, and mercenaries looking for distraction.

And every evening, Guillaume placed an egg on the table.

“Make it stand.”

The laughter always began the same way.

Then came the attempts.

Hesitant fingers.

Clumsy movements.

Hardening stares.

Guillaume never looked at the egg.

He watched hands.

Shoulders.

Silences.

He knew.

Before the egg even touched the table, he knew who would fail.

And they all did.

His coin purse grew heavier.

His smile never changed.

That evening, however, something shifted.

A man sat down without a word.

He did not touch the egg.

He watched.

For a long time.

Too calmly.

Guillaume noticed him immediately.

“How much have you made with this?”

The voice was calm. Almost indifferent.

“Enough to avoid working.”

A brief silence.

Then a faint smile.

“I’m not interested in the egg.”

Guillaume barely looked up.

“Then what?”

“You.”

One eyebrow rose.

“Strange way to flirt.”

Todd did not react.

“You’re wasting your time here.”

A silence settled.

“You never look at the egg.”

A pause.

“You look at people.”

The noise of the tavern seemed to fade.

“You read them before you face the problem.”

Todd folded his arms.

“That’s why you win.”

He gestured toward the room.

“They see an egg.”

“You see their mistakes.”

A brief silence passed.

“You’re making money off drunkards.”

“I’m making money off nobles.”

“You have talent.”

“You’re wasting it here.”

Guillaume laughed, openly.

A little too quickly.

“Still recruiting, Todd?”

A beat.

“For the fourth time.”

“And for the fourth time, no.”

“Why?”

“Because I like choosing where I go.”

“Because I choose my contracts.”

“And because leaders have a habit of thinking they’re smarter than me.”

Without replying, Todd reached for the egg.

The silence this time was real.

A few heads turned.

Guillaume did not move.

But his eyes never left the gesture.

A light tap.

Almost nothing.

Todd set the egg down.

Balanced.

Time seemed to hesitate.

Then resume.

Murmurs returned.

Guillaume remained still.

His gaze shifted from the egg… to Todd’s fingers… then to his face.

A smile formed.

Slow.

Genuine.

“Well?” Todd asked.

Guillaume exhaled softly.

For the first time in a long while…

he had not seen it coming.

“Alright.”

He nudged his coin purse forward.

“I suppose you win.”

A brief silence.

Then, quieter:

“…but don’t expect me to enjoy taking your orders.”

That night, Guillaume joined Todd’s mercenary company.

Over the years, they traveled roads where loyalty was sold as easily as steel. Merchants, nobles, organizations—it did not matter, as long as the contract held.

Guillaume never grew used to taking orders.

His arguments with Todd often ended in disagreement, sometimes in insults, and more than once they nearly parted ways.

Yet year after year, Guillaume remained.

The reason was simple.

Todd was arrogant.

Dominant.

Demanding.

But he delivered results.

When he said a contract could be done, he found a way.

In the mercenary trade, that was often worth more than anything else.
