[Musutafu City, Japan]
At a playground near the local school for children below 5 years.
"Kagama! I told your quirkless ass to not mess with me!" The kid, Katsuki Bakugo said.
"K...Katsuki, I just answered the question which the teacher asked." The kid Kagama told to Katsuki.
"A QUESTION THAT I COULDN'T ANSWER! I NOTICED YOUR SMUG FACE LOOKING AT ME!" Katsuki pushed the Kagama onto the ground. He began walking towards Kagama.
"AHA! Look at this dumbass. Quirkless and useless." Katsuki taunted a helpless child. The child was quivering with fear with each step Katsuki took.
"Bakugo, please, please just leave me alone." The child pleaded as Bakugo threw explosions at him. "SHUT UP!" Katsuki kicked him. The three kids along with Katsuki began laughing.
He threw an explosion that sent the boy flying away a few yards. Before Kagama could wake up, Katsuki threw another punch that pummeled the kid into the ground.
"Bakug-" Kagama's sentence was cut short by another punch. When Katsuki pulled back to deliver another punch, another child came in between them. The child's emerald eyes glowed pristinely in the sunlight.
"Izuku? What are you doing here?" Katsuki asked. The child referred to was none other than Izuku Midoriya. He was a friend of Katsuki.
Of course, in this hero society, those with quirks are deemed...superior. Those who have been declared quirkless are as useful to society as animals, You may object to that statement with the fact that some people do not think that way, and you would be correct. However, the sad truth is that society does not share the same opinion.
"Kacchan, please leave him alone." Izuku said, mustering up his courage.
"DEKU! Get out of my way." Katsuki pushed Izuku aside. As he raised his fist to hit the other Kagama, just before he landed the punch, his fist contacted not the child but Izuku.
"Kacchan, I-I won't let you hurt him," Izuku said. "This is not what being a hero is."
"SHUT UP!" Katsuki punched Izuku but Izuku stood up again. He punched him again, and again and again. But Izuku, he kept rising. His face was now bruised but his spirit was unwavering.
"Kagama, we're classmates, right? I heard you were super smart." Izuku said while smiling. He looked at Katsuki who was trying to kill him...that's what he looked like. Katsuki swung his fist onto Izuku's face but in the nick of time, Izuku ducked below.
"KACCHAN!" Izuku yelled as he dodged another punch. Izuku ran against Katsuki and managed to grab Katsuki's hair. He pulled it down causing Katsuki to fall. Before, Izuku could react he was blasted off by an explosion.
He stumbled across a few yards. He let out heavy pants. Suddenly, Katsuki tackled him and began barraging Izuku with punches. Punch. Punch. Punch. Punch.
Izuku's nose was now broken with him bleeding profusely. "I can't fight you but I won't let you win but once I get my quirk...," Izuku said as he was nauseous. "Katsuki." Suddenly, a soul, unknown to this multiverse collided with Izuku.
Katsuki's eyebrows twitched in annoyance. He ran at Izuku but then. A greenish crystal zone surrounded 10 metres radius. Time Stop. A voice rang out but it was not the voice of Izuku.
Izuku opened his eyes to see Katsuki frozen in his place. The fountain's water was still. The birds hung in the air. He moved behind Katsuki in a short time and then. Resume.
Izuku was not the one in control now—it was the soul that collided with his own, bursting into his mind with overwhelming force.
"HAHAHA! HA HA HAHAHA! I HAVE ARRIVED!" Izuku's voice echoed as the being inside him revelled in its triumph. "My attempt to cross into another world is successful! I, Chronos, the god of time, have achieved immortality!" The laughter was relentless. "And it seems... ah yes, a part of my power followed me through. Wonderful." The god, now fully in control, gazed around the world with curiosity. Then, he sneered. "You, pitiful human… why are you here? What is your purpose in this insignificant existence?"
Katsuki Bakugo raised an eyebrow, glaring. "Izuku! What the hell are you saying, you damn nerd? Are you dumb or what?" he said.
Chronos slowly turned his head. Izuku's familiar, kind eyes were gone. "Humans never learn," Chronos muttered. "Whatever the world, they're all the same."
With a flick of his hand, time obeyed.
"Time Stop."
The entire world froze in an instant. Katsuki's scowl froze halfway through a twitch. Everything stopped—except Chronos, wearing Izuku's body. He approached Katsuki's immobilized form, raising his fist high.
Punch.
His knuckles connected with Katsuki's chest.
"Time Resume."
In the blink of an eye, Katsuki was launched through the air like a cannonball, slamming into the earth meters away, leaving a cloud of dust. He groaned, clutching his ribs in pain. "Deku, what the hell?" he wheezed.
'Who… Who are you?' Izuku's voice echoed.
Chronos was startled for the first time. 'You… A mere mortal? How are you still here? No human mind should survive my possession!' The disbelief in his voice was apparent.
But Izuku's voice came again. 'I said… Who are you? What do you want from me?'
Chronos scowled. "Foolish boy. You should not even be conscious, let alone capable of speaking." He sneered, but there was a hint of curiosity in his ancient voice. "Very well. If you wish to know the truth, then hear it: I am Chronos, the god of time—eternity given form. I bend time to my will, and this body of yours belongs to me now."
Izuku's mind shouted in defiance. 'This is MY body! You don't get to take it from me!'
Chronos chuckled, amusement in his voice. "Ah… such naivety. Your courage is admirable, child, but courage alone cannot stand against the inevitable flow of time. I am not some simple villain or passing threat. I am eternity itself, I can wait forever. Can you?"
But Izuku, 'I don't care how powerful you are… or how long it takes. I'm not giving up. Not ever.'
Chronos sneered, intrigued by the boy's tenacity. "How amusing. Very well, mortal. Let us see how long your spirit endures… for time, after all, is on my side."
Suddenly Chronos fell onto his knees in pain. As his eyes went white, Izuku's consciousness came back. Izuku began gasping for air as he lay down. 'Seems that the universe sent me into you, young mortal. You seem to be able to withstand my power, let us see how you hold up in the grand scheme of things.'
Before Izuku could respond, he fell to the ground.
