The main character is Crim Fury. The boy who travels from world to world in search of his home and memories. However this caught the attention of the Truck-kun the god of Isekai.
—----------------------------------------------------------------------------------------------------------------------------
"Sir, there seems to be an anomaly in one of the worlds." one of the goddess remarked while she monitors the worlds through a scrying glass.
"This person…." mutters Truck-kun as he watches through the scrying glass with the goddess. The boy… every step he took had intent, every action he made had purpose, it was evidently clear that the boy did not come here by accident. Through the scrying glass, Truck-kun sensed overwhelming power emanating from the boy. Did perchance the other gods send this boy here?
"Should I send someone to dispatch him?" asked the goddess.
"No, I will take care of him myself." replied Truck-kun. If what he surmises is true, then this adversary was too much for the other "gods" and "goddesses" of this world to handle. The worlds that he curated, the worlds that he worked so hard to create, could all be destroyed by this single individual. Whatever reason this boy entered this world, he must be eliminated.
Crim looks at his watch/compass as he walks through the city-like area.
I'm going in the right direction. He thought to himself. For there to be so many buildings, there was not a single person outside. While it doesn't pertain to him, he couldn't help but wonder, what could be the reason? Is it a holiday for these folks? Is it dangerous outside? Hmmm maybe there is a monster.
**Crash**
Suddenly, a giant humanoid truck appeared before him. The truck monster glared at him with menacing bright lights, engines revving loudly, and exhaust spewing behind it. It was Truck-kun.
Unfortunately, it was in the middle of day, Crim could not notice the bright lights from the truck monster. Hmmm perhaps this world is inhabited by truck peoplleeaaaaAAAAAAAAA "AAAAAAAAAAAaaaaaaaaaaaa!!!....."
Before finishing his thought, Truck-kun punts Crim into the air like a soccer ball. In a split second, Crim was now in another fantasy world, it was lush with green forestry, a castle can be seen from afar, animals roaming arou- THWACK! Suddenly, Truck-kun warps behind Crim and punches him into another fantasy world, the sky gleamed in twilight, there was a cool chilling breeze in the air, dust raised from the- BAM! Suddenly, Truck-kun appears in front of Crim and double-fist slams him downwards, sending Crim into another fantasy world, the world had a futuristic - WHAM! Truck-kun sends Crim into another fantasy world.
With Truck-kun's barrage of attacks, Crim visited multiple worlds within a few seconds.
Crim crashes into a big floating rock. This world has asteroid-like rocks floating in mid-air, on top of them are glowing crystals that lit up this dark world, below are floating islands occupied with temples and rubble. The creatures that roam the temples emanate purple smok - CRASH! Suddenly, Truck-Kun appears in front of Crim yet again and launches another punch towards him. However, this time it missed. Crim successfully dodges Truck-kun's attack, now is time for a counter-attack.
The stage is set, the rubble and debris from Truck-kun's punch floated around the two. Crim leaps from the asteroid-rock at 1300 kph and lands on a small pebble. He then leaps off the pebble towards Truck-kun and commences his attacks. This was Crim Fury's ability. Whenever Crim enters a new world, he would sometimes attain an ability that might help him on his journey. Some abilities appear more frequent than others. Crim named this one "Burst Speed." While a simple name, "Burst Speed" allows Crim to essentially become almost weightless and able to stand on objects no smaller than 6.5 mm in midair. Not only that, on record, Crim's initial velocity increases by 150 - 2000 kph, depending on the world.
Rock, arm, torso, rock, leg, other leg, moving to the back, back to a rock, back of the head, repeat. Crim maneuvers back and forth between the floating rocks and Truck-kun, launching a flurry of punches and kicks for every moment he was on Truck-kun. However, it was futile. Crim placed all his might into every single attack, but it only resulted in small, light dents to Truck-kun's exterior, no significant damage was made.
"Hmmf! What's fruitless effort! No matter how strong you are, you could never hope to defeat me," proclaimed Truck-kun.
Oh, so this thing can talk. Crim stopped his attacks against Truck-kun and stood on a floating piece of debris. "Truck monster, why are you attacking me?" He pointed towards Truck-kun demanding for answers.
Truck-kun's eyes shined even brighter. In this dark world, the light was blinding.
"MONSTER? I AM NO MONSTER, I AM A GOD!" Truck-kun's engine revved with such ferocity that the world they occupied shook, debris from the temples fell, some even started cracking, the dark creatures moved away and took shelter. "MY REIGN IS OVER MANY WORLDS! THOSE WHO INHABIT MY DOMAIN, NO MATTER HOW POWERFUL THEY ARE, NO MATTER HOW POWERFUL THEY BECOME, THEY WILL NEVER BE AS POWERFUL AS I! THE GODS AND GODDESSES, THEY SERVE UNDER ME AND ME ALONE! NO ONE IS ABOVE ME, NOBODY CAN DEFEAT ME, TRUCK-KUN!"
"Hmmm, then that makes me a nobody huh?" Crim grinned with smugness, chuckling at his own joke.
"...What a foolish being you are. To have the audacity to mock me, a god, and have the audacity to believe you are on the same level as me. Invader, I will destroy you, for the safety of my world and the worlds I oversee. Your very existence is a threat to my world."
What? Crim pondered on what Truck-kun meant. What does he mean that I'm a threat? What did I do? What could I do? Before Crim had a chance to ask, Truck swatted him off into another world.
Truck-kun took a moment before warping to the next warp. His engines felt like they were overheating. His cooling fan worked overtime to keep his temperature cool. Truck-kun felt despair. He felt panic, he felt anxiety, and more importantly, he felt fear. This invader, how? HOW?!! Dents!? Considerable amount of coolant started leaking out of Truck-kun's body. Truck-kun's gallant outward appearance, his bravado began to crumble. Nothing should be able to injure me, not even as much as a dent! I am a bonafide true god! Nothing should…"
A few moments pass as Truck-kun tries to regain his composure. I must eliminate the invader as soon as possible! Truck-kun warps on to the next world.
The next fantasy world is similar to the first. Scenery is full of lush forestry, wild animals roaming, peddlers moving their wares, adventurers looking at their map towards their next destination, clear blue skies, small rocky mountains, the invader was nowhere in sight. "You… YOU THINK YOU CAN RUN FROM MEEE!!?? THERE'S NOWHERE YOU CAN ESCAPE, NO MATTER WHERE YOU GO, I WILL CATCH YOU!"
5 km away from Truck-kun's location, Crim hid in a cave within a small mountain. He leaned against the wall that was in front of the cave's entrance. The wall blocked out Crim's body and silhouette from the outside. Taking a breather, Crim could finally assess the situation. Dammit, that might've been my one and only chance to defeat him. I no longer can use "Burst Speed" since I changed worlds. While I ran around on his body, there didn't seem to be any openings. I'm not small enough to enter through the gaps either. Crim starts to feel pain that he didn't notice, coursing all over his body. It seems that my adrenaline is starting to wear off, it's a miracle that I was able to tank all of Truck guy's hits as I flew all over the place, but it won't be long before I end up like a splattered bug on his windshield. Crim moves his head closer to the edge of the wall and peeks outside. He also called me a threat earlier. I want to know what he means by that. It could be a misunderstanding. But I don't think he will listen to me unless I kick his ass, and only then can I… I…
"FOUND YOU"
While it is daytime, the truck's blaring lights crept through the darkness of the cave. The loud truck horn echoed into its walls. The smell of exhaust and the sound of the engine seeped into the cave. Crim's pupils constricted, the adrenaline that was slowly fading shot right back up. Crim makes a mad dash deeper into the cave. That's his arm right? It should be about 40 meters long. I just need to sprint a little further and I should be out of his reach. Crim looks behind him, to his surprise, he did not expect this predicament. NO WAY… THE ARM… IT'S DETACHED FROM THE MAIN BODY. IT'S STILL FOLLOWING ME! The horn shrieks behind him, bashing into the walls breaking the structure of the cave.
SHIT SHIT SHIT! IF I GET HIT, I"M DONE FOR!!! The cave curves towards the right, the truck turns sharply, shredding the wall of the cave. Right now, even without "Burst Speed" I can run as fast as 60 km per hour, but the truck can't speed up faster than 55 km per hour because of the cave's terrain and its narrowness. As long as I can keep up this pace, the truck can't hit me. As the chase carries on, Crim sees small green creatures that resembled bald ugly children with pointy knife ears and pointy teeth ahead of him. Ah this cave already has dwellers occupying it. The bald ugly children notice him running towards them. They snarl and ready their spears, clubs, and bows for an attack. And they don't seem very friendly either. A truck from behind and a horde of creatures at the front, Crim is caught in a pincer attack.
As Crim gets closer, the creatures leap towards him, one of them lunges their spear at his body. Crim evades the attack and continues moving forward. He immediately punches one of the creatures ahead of the spearman while maintaining his speed. Another tries to bash Crim with a club, but Crim hurdles over it immediately and pushes off its face with his hand to gain a little bit more momentum. One of the bowmen locks its arrow and aims it at Crim, but it gets runovered by the menacing truck from behind.
Crim needed to move perfectly, any impediment to movement, any successful attacks towards him, could become catastrophic for him. Crim evades, counters, and parries every single attack coming towards him. His gracefully spins, passes, and jumps over every one of the hostilities in front of him. Every being that he passes becomes roadkill for the truck.
Crim continues to run until he reaches what seems to be the nest of the green creatures. This time there were more, way more of them than the horde guarding the path. They stopped whatever they were doing and focused their attention on Crim, who stood before them. Like the guards, they readied themselves to battle against the intruder of their den. They had what seems to be a shaman casting a spell in the back line. The bowmen took aim, swordsmen and clubmen raised their weapons, and the spearmen pointed their spears.
But Crim's attention was not to the creatures but to the area itself. Shit, it's a deadend! But it's spacious. Maybe I can- The scene unfolded in slow motion, the truck's horn sounded as it barreled into the den, the creatures swarmed the intruder, and the intruder dove, tucking and rolling to the entrance's left side. Ultimately, the truck plowed through the creatures and slammed into the cave's rear wall, creating a small exit to the outside.
