Engine Legs walked onto the Omega Tofu Stage.

Prince Icy Hot walked onto the Omega Tofu Stage.

They looked each other in the eyes.

Mic Man was still announcing the festival. "It's the semifinals Sports Fans! I know those bets are being made at the betting booth! Go ahead and cast your bets now! Who know how this match will turn out? After all, both contestants are descended from professional hero families! It's Glasses Guy Engine Legs versus Half White Prince Zuko! These students are the top of their class! By the way, did you notice that the semifinalists are all from Class 1-A? Mr. Ninja Turtle, your students are doing so well! What's your secret?"

Mr. Ninja Turtle replied, "Hard work, dedication, and intense training. Every week, I meet with each student for one-on-one sessions for goal setting—"

"Wow he works hard! You can't find teachers like that just anywhere folks! Which student is he rooting for? Which student will win? Let's find out! Battle, START!"

Ice Prince used Ice Rush!

Engine Legs dodged and sprinted around the stage.

Ice Prince used Ice Rush!

Engine Legs was trapped between two walls of ice. Not even fazed a bit, he squatted, and proved that his hamstrings and glutes were just as powerful as his calves.

"He did a standing long jump!" both Blushy and Green Boi exclaimed.

Yes he did. And then he used, "Super Nitro Leg Boost!" to maximize his leg power. He tried to kick Ice Prince in the head, but Ice Prince dodged. But Legs Boi twisted in mid-air and, WHACK!

He kicked Ice Prince on the head. Quickly, he grabbed Ice Prince by the collar of his shirt and dashed like mad to throw the Prince off of the stage.

But he underestimated the Prince, and apparently he forgot that the Prince could freeze whoever he touches. Before he even realized it, Engine Legs was trapped in a pillar of Ice.

The Sexy Lady shouted, "Engine Legs can't move! Prince Zuko wins!"

"It-it can't be!" exclaimed Legs Boi. He shivered, and whimpered, "I failed, Big Bro…"

"You're no match for me," The Prince said as he rubbed the back of his head. A welt was already forming. "But you sure are fast," he grumbled, as he walked off the stage.

"Hey, come back here and defrost him!" Sexy Sadist Lady demanded.

…

"The next match is the terrifying creature of darkness versus the terrifying creature of rage!" Microphone Speaker Man shouted. "It's Dark Demon Bird Boi versus Angry Explosion Boi! Who will win? Place your bets! Battle, Start!"

Angry Boi, of course, started off the battle with a barrage of explosions.

THE LIGHT! IT BURNS! Little Peepers hissed telepathically.

Bird Guy grunted, and tried to dodge Explochan's flashy superpower.

NO! KEEP IT AWAY! THE LIGHT, IT BURNS US!

"Stay calm Little Peepers," said Birdy Boi. But the situation wasn't good. Not good at all. Explochan was rushing at him, exploding all over the place. Bird Boi couldn't keep up. And he was running out of darkness. He wouldn't last much longer.

Up in the stadium, Blushy asked Green Boi, "Didn't Birdy-kun say something about being weak to light?"

Beside her was Tits-chan and Acid Girl. They gasped. "Is that why he's being a wimp?" Acid Girl asked. "Because he embarrassed the hell out of me during my battle. Now all of a sudden he's acting like a scrub."

Red Head, who was sitting behind them, leaned forward and said, "Oh, he's weak to light? I guess every quirk does have a weakness." Tape Boi, sitting to his left, added, "Oh so then it just sucks that he ended up fighting Explodey-kun."

Pikachu Dude groaned, "Aw man if he was up against me during the first round, then I could've won!"

Earphone Chick said, "No, you'd probably just use your million-volt shock and fry your brain again."

All of them were startled by a particularly loud explosion, and a bright flash of light. Explochan shouted, "Super Flashy Quirk Attack!"

Explochan had pinned Bird Guy down, grabbing him by the beak, while sparking bright flames from his other hand, like the world's angriest firecracker. "Give up and die, loser."

"B-but how? How did you know my weakness?"

"Your stupid bird thing was screaming about it."

"Y-you can hear Little Peepers? But, but that means…"

Bird Guy had a flashback to his youth, when he had first sold his human face to obtain Little Peepers. He had acquired this power from a crazy old woman. She possessed a bow and arrow that either granted you supernatural powers, or killed you. He still remembered the pain he felt as the old woman shot him in the belly with the arrow.

But it was worth it. There was no other way a quirkless kid like him could have gotten a super power. And the first time Little Peepers spoke to him, Bird Guy was surprised that no one else could hear it.

Only those with hearts full of pure darkness can hear my voice, Little Peepers had told him.

"Darkness?"

In this world, there are people whose hearts embody one of the seven deadly sins. Greed. Lust. Gluttony. Wrath. Sloth. Pride. And Envy. You, my Master, embody the sin of envy. You so desperately coveted a quirk that you were willing to go to such lengths to attain one. Now you are cursed, and must forever bear the burden of my endless desire to feed on mortals.

"Very well then…"

Right now, looking up into Explochan's violent eyes, Bird Guy realized that not only was Explochan's quirk more powerful than his, but the darkness in Explochan's heart was orders of magnitude stronger than his. There was so much wrath… or was it pride? Or… or both?!

Explochan may have beaten his opponent with light, but it was his darkness that caused Bird Guy to say, "I surrender."
