Hero From The Toilet
Fantasy
10
Rangga just wanted to take a dump in peace.
His life was already complicated enough. Living in a boarding house, working odd jobs, and struggling to keep up with college.
But that night, the old toilet he usually used suddenly changed.
A magic circle appeared beneath him.
A group of robed figures in another world were summoning a “hero.” And somehow, the one they got was Rangga.
No special powers.
No grand destiny.
Not even a chance to prepare.
In a world filled with magic, monsters, and kingdoms, the only things he has are logic, recklessness, and whatever little physics he happens to remember.
But sometimes, the most dangerous person isn’t the chosen hero, it’s an ordinary man who doesn’t know when to give up.

Chapter: 10. I Think I Accidentally Invented Disaster Magic
But Rangga wasn't finished. He raised his hand again, imagining ionization and plasma. The air inside the vortex began to glow blue.ZZZT!Sparks of electricity appeared between the colliding stones, building an increasingly powerful static charge."RANGGA!" Arcelia shouted.The tornado was now glowing. Plasma flashed inside the vortex while electricity jumped from stone to stone, filling the air with a violent hiss.ZRRRRRRT!It was no longer just a tornado. It looked like a miniature energy reactor spinning in the middle of the valley.Arcelia backed away even farther."THAT'S NOT STABLE!"KRAAAK!A small bolt of lightning struck the ground, sending dust flying as the winds throughout the valley became increasingly violent.The guards immediately panicked."WHAT IS HE DOING?!""GET AWAY FROM THERE!"Arcelia kept her eyes fixed on the vortex."...You created a storm."Not an ordinary storm. It was a storm of wind, plasma, and electricity, continuously spinning and even beginning to g

Chapter: 9. Apparently, Rocks Can Be Guided Missiles
The molten metal moved as if guided by an invisible hand, spreading out and reshaping itself into several curved metal plates of different sizes.Arcelia stared sharply."...You're forging without a hammer."Rangga raised his hand. Moisture in the air began to gather, forming droplets that immediately fell onto the heated metal.SSSSSSHHHHH!White steam burst into the air as a sharp hissing sound echoed across the valley.A few seconds later, the iron plates darkened. Solid, Hard and finished.The valley fell silent again and Arcelia walked closer, picked up one of the plates, and tapped it.Ting.She turned the plate over in her hand."...You just did something that normally requires a furnace, a blacksmith, a hammer, and hours of work... in less than a minute."She looked at Rangga."You even shaped it directly."Arcelia let out a quiet sigh."...Rangga. You're not just experimenting."She glanced toward the carriage, then back at the metal plate in her hand."...You're creating tec

Chapter: 8. Who Needs a Furnace When You Have Plasma?
The carriage finally came to a stop, its wooden wheels creaking softly against the rocky ground as the coachman pulled on the reins, bringing both horses to a halt in front of the old mining valley.The place was silent.Gray rocky hills surrounded a vast basin, while several dark mine tunnels gaped open along the hillsides like the mouths of caves. Old wooden supports still stood in several places, but it was obvious that the mine had been abandoned for a long time.Rangga climbed down from the carriage, and the moment his feet touched the ground, he stretched his body with a groan."Ugh... should've made some springs or something."Arcelia stepped down far more elegantly before glancing at him."Springs?"Rangga pointed at the carriage."To reduce the shaking."He walked over and immediately inspected the underside of the carriage. There was no suspension system, only a rigid wooden frame connected directly to the wheels.He knocked on the frame."See?" he said, pointing at the whee

Chapter: 7. I Should Probably Not Make a Black Hole
She stepped closer and stopped in front of the table, her eyes dropping to the book in Rangga's hands."...Is this part of some plan of yours, or are you genuinely just curious?"Rangga immediately raised one hand."Hey, don't blame me."He pointed toward the window."I didn't know you guys considered light magic to be illusions and stuff. Your concept of light is different from mine."Arcelia stared at him for several seconds before letting out a small sigh."...That is true."She stepped closer to the table and Rangga pointed toward the page about earth magic."This one. I can't experiment with this here."Arcelia raised an eyebrow."Why?"Rangga pointed at the illustration."If I experiment with it... I'm worried I might accidentally move a tectonic plate."Arcelia blinked."...A tectonic what?"But Rangga was already continuing."Then the castle really will disappear."Silence.Arcelia stared at him for a long moment before finally speaking quietly."...You're right."Rangga looke

Chapter: 6. Science Is More Fun with Mana
She looked at Rangga again."But that does explain something—the mana of this world reacts extremely strongly to you."Her mind returned to the hole in the castle wall."What you did earlier wasn't simply using mana..."She narrowed her eyes."You treated it like a tool." Arcelia continued, "We need to conduct several more tests."She paused."...And no, you do not need to show me the Sigil." Then, in a dry tone, "...I would prefer not to see it."Rangga suddenly raised his index finger."So if I want fire... something like this?"He closed his eyes. In his mind, he wasn't simply thinking of the word fire.He was thinking of a concept plasma. Ionized gas. Electrons stripped away from atoms.In his world, creating it required extremely high temperatures but here there was mana.Arcelia immediately sensed a change in the air. Not heat, but energy pressure.She stood up."Wait—"Too late. A bluish-white spark appeared at the tip of Rangga's finger.Zzzzzzt—The air hissed softly and Arce

Chapter: 5. My Hero Sigil Is on My Butt
The King gave a small nod, as though that made perfect sense and Rangga continued casually."I need an assistant—someone who at least knows how this world works and what's going on around here."The elderly mage nodded."That can be arranged.""And I need a house or somewhere to stay," Rangga added."That has already been prepared," the King replied without hesitation.Rangga nodded, then added in exactly the same casual tone,"...Also, I still haven't wiped my ass after taking that shit earlier."For several seconds, everyone simply stared at him. The young mage immediately turned away, his cheeks turning red. The guard captain covered his face."...Gods above."Several knights finally burst out laughing. The elderly mage rubbed his temples."...Very well."The King let out a long sigh, clearly suppressing a smile."That is... an extremely reasonable request."He then turned toward a woman in dark blue robes who had been silently observing everything from the sidelines."Arcelia."Th
