Z-City, 1:01 PM

"Hey, where did Demon Cyborg go?" Mumen Rider asked after noticing a lack of input from him in a while.

"Weren't you listening?" Tatsumaki scolded. "Child Emperor told him to run to Caped Baldy's house and pick up a personal belonging of his that he's touched recently."

"...Okaaaaaaay?"

"You don't even know why, do you?"

"Don't be so hard on him," interjected Atomic Samurai. "It's kind of hard to keep track of your surroundings when it's this boring."

"Ah, speak of the devil," Fubuki said, pointing down the block.

Everyone turned their heads to Genos as he sprints towards them, shooting rockets out of his palms to accelerate himself. He stopped the rockets and slide to a halt in front of an unflinching Bang. A black skid mark stretched for several meters behind him.

"Sorry for the delay," he said, holding a green gym bag underneath his right shoulder.

"How did that not catch on fire?" questioned Tatsumaki.

"Ah, just in time," said Child Emperor using his pinchers to walk. In both hands, he held a black cube with a white circle holding a black "8" in the center of one side. "Ladies and gentlemen, allow me to introduce the 8-Cube. It allows us to travel between dimensions and doubles as a DNA tracking device. With this, we should be able to track Saitama no matter which universe he is in."

"So that's what the bag is for," Mumen Rider said.

"Yes," Genos confirmed. He unziped the bag and revealed several folded boxers, socks and a pale indigo tooth brush. "However, I could not decide what which would be the most effective item in tracking sensei. So I brought all of them."

"...What the hell…" Speed-o'-Sound Sonic whispered.

"That's, a bit of a stretch, doncha think?" asked Atomic Samurai.

Fubuki covers her mouth with her left hand as her right cups her elbow, blushing.

"Is that a stain?" Mumen Rider asked as he paled slightly.

"What kind of stain is that?" says Puri-Puri Prisoner.

"Ahem," Child Emperor faux coughed. "Give me a boxer, stained preferably."

Genos' eyes scan through the gym bag as he rummaged through it. Various charts appeared in his vision, observing each pair of boxers for the quality of stains. He heard a beeping sound as he focused on a gray pair with a dark stain in the center of it. He shamelessly picked it up gave it to Child Emperor.

"Thank you," he said as he puts a pincher through the entrance of the boxers. He brought it half an inch away from the 8-side of the cube. The top of the circle emitted a thin green light that traveled down the boxers. Child Emperor placed the cube on the ground and stepped away from it. In about a second, a bolt of purple lightning shot out of the left side of the cube, creating a wormhole in the process.

Inside the wormhole was an image of another cleaner, and semi futuristic city.

"This is the universe Caped Baldy is currently in," Child Emperor announced.

"W-wow," said Puri-Puri Prisoner in awe. "I've been inside some sketchy holes but this one takes the cake."

Speed-o'-Sound Sonic turned to him.

"Why is everything sex with you?" he asked.

"Well, here we go." Child Emperor said as he walked towards the wormhole. Genos walked directly him as he has been eager to do this since the morning. Mumen Rider gulped and walked his bike to the portal. The rest of the group soon followed.

"Has this thing been tested?" Fubuki asked folding her arms.

"This is the test," responded Child Emperor without looking at her.

Fubuki squinted in annoyance as Child Emperor put on a sly smirk.

The group of heroes stepped into the wormhole leading to an unknown world, surely ready to take on trial in order to save their friend from unknown perils.

...Or so they thought.
