A shining light came from the old structure of the Hakurei Shrine, now residing in City Z. Reimu and Sanae's aura grew dim as they finished a spell they were casting.

"There, this barrier boost should protect the shrine from these monsters when we're not around...hopefully." Reimu said sounding a little unsure, she still needed to get used to the new laws and rules of the new universe. Meanwhile all of the other girls were hanging out also adapting to their new environment.

Starting from Marisa, she and Alice have begun to look at the new books Patchouli picked up. Remilia just sat around waiting to bother Reimu. Aya was starting to research in all the News studios the humans had, she was both extremely interested and jealous. Youmu, well she takes frequent walks while also thinking about Yuyuko. All the girls were sitting around bored until Reimu suggested they head outside.

Bored out of their minds the girls complied. As soon as they did they felt something zoom past them rivaling Aya's speed. They had to hang onto something to keep from blowing away.

"What the hell was that da ze?!" Marisa exclaimed fixing her hat. Aya got some leverage in the air; she hovered a hand over her eyes and squinted. She saw a familiar shine and grinned.

"It's Mr. Baldy!" She exclaimed.

"That was Saitama-san?!" Sanae exclaimed in disbelief.

"Wonder what he was running to?" Youmu said making all of the girls wonder themselves.

"Ah, you all are gathered in one place." Genos walked up to the group showing his usual attitude.

"Genos-san why are you here?" Sanae asked.

"I was wondering if I could ask you all questions?" He asked. The girls glanced at each other and then looked at him suspiciously.

"Why?" Reimu was the first to ask.

"I can see why you all would be suspicious, but I have my suspicions as well and I was hoping you all could clear any confusion." Genos explained calmly while he faced the suspicious looks, even some glares from the girls.

"Well...it wouldn't hurt. But Genos-san please don't disclose any information we give of Gensokyo to anybody else. We don't want anything bad to happen." Sanae said giving a little stern tone.

Genos nodded, "Understood." But then he thought for a moment.

"What about Sensei?" He asked.

"Alright, but you two only no one else!" Reimu exclaimed. Genos nodded again and they all backtracked into the shrine.
------------------------------------

"So....Gensokyo is like a different world? And it's inhabited mostly by beings called Yokai huh?" Genos asked. They spent about 2 hours discussing and disclosing information.

"That's right, it's completely cut off from other worlds. No one can come in or out...well some are an exception." Sanae explained.

"If that's the case...how'd you all end up here?" Genos asked. Reimu bit her lip thinking very hard about this decision, but seeing as how the past attempts at getting home proved to be useless she decided to bite the bullet and just tell him.

"Well," Reimu started and then sighed, "The barrier that separates Gensokyo from the outside world has been weakening." She said. Genos still didn't understand so Sanae elaborated.

"When the barrier weakens, it could give the Yokai a chance to come to the outside world and wreak havoc upon humans. If it collapses who knows what chaos could ensue." She said worriedly. Genos thought for a moment, and he looked at the worried expressions of both Reimu and Sanae. He was convinced this wasn't a story they thought up on the spot.

"Alright. And that's the reason why you were so desperate on getting back?" Genos asked.

"Yes." Reimu said.

"Also..." Genos trailed off, "I was wondering if I could assist you." He finally said.

"Ehh?! You wanna help us?!" Marisa asked in shock.

"Yes, not only to help you all, but for the safety of this world as well." He said determined. Sanae pat his shoulder while giving a big smile.

"Well we could use whatever help is necessary." She said.

"Right." He nodded and then stood up.

"Oh? Where are you going?" Aya asked curiously.

"Back to Sensei's home, I'm now living there. And her should be back any moment, I'll take my leave." He said bowing and heading out the shrine doors.

"I don't see why you put so much trust in him Sanae." Remilia said once Genos got out of their hearing range.

"Well, who else can we trust. I mean we have known Genos-san and Saitama-san here for a while now. Plus who knows maybe they can help?" She suggested, Reimu shook her head already done with all of the unnecessary stress.

----------------------------------
The next day, Youmu and Aya were out wandering the streets. They were the next ones to gather the groceries, or as Marisa called it "food stock."

"Mr. Baldy!" Aya suddenly called out as she rushed over to Saitama. Youmu shook her head exasperated as she jogged over to the commotion. Saitama gave an annoyed glare to the excited tengu.

"Don't call me that!" He exclaimed.

"And Mr. Ninja too!" She said excitingly taking out her camera.

"I JUST SAID MY NAME WAS SPEED O' SOUND SONIC!" He yelled loudly clearly more than frustrated.

"Well you all together makes my job easier, today's the day I will-"

"Sorry but I'm kind of busy, can we do this later." Saitama cut him off nonchalantly and just kept walking. Sonic did not look happy as he got out his sword. Youmu saw this in the corner of her eye, and on instinct she got out her main sword as well.

"You think you can esca-?!" Sonic was caught off guard and was forced to block an incoming attack from Youmu. The two swords clashed, the commotion catching the attention of the people surrounding the area.

"What?! What do you think you're doing?!"

"You want to fight so badly? I'll give you a challenge." Youmu said pointing her sword in front of his face. Her ghost half flew next to her and gave her an even more intimidating look. Sonic grit his teeth, he wasn't about to let his chance to fight Saitama go to waste. He ran disappearing from Youmu's line of sight.

"Crap I forgot he was fast!" She exclaimed running to that direction. Sonic swung his blade towards Saitama, however before it could make contact he bit straight through the sharp metal.

"I just said I was busy, now piss off before I punch you." He said irritated it made Sonic, and even Youmu and Aya got shivers. Saitama once again set off walking, while Sonic growled in irritation.

"Ahh! It's that suspicious person!" A girl exclaimed cutting off all the action. A girl with a bun was pointing to their direction was screaming obnoxiously loudly.

"Halt there suspicious person! Tank top Tiger is calling you!" A burly man in a striped Tank top who went by the name Tank top tiger, showed off his muscles to the crowd. Both Aya and Youmu gave a deadpan stare to the man.

"There! That man was acting all suspicious yesterday." The girl called.

"Heh, hey Sonic. They're calling you out for being all violent-"

Tank top tiger harshly placed his large hand on Saitama's shiny head, "She means you cue ball." He said.

"Wait what?"

"Ehhhhh?!" Aya exclaimed loudly in confusion catching some unwanted attention.

"If I may ask, why is he suspicious?" Youmu spoke up.

"He was running around yesterday with a weird, angry look on his face!" The girl pipped up again. Youmu gave an annoyed stare at her before turning her attention to Tiger again.

"But isn't Mr. Baldy a hero too?" Aya asked.

"For the last time don't call me bald!" Saitama yelled at her.
"But she's right I am a hero!" He argued trying to prove at least some innocence.

"I, Tank Top Tiger, have never heard of you! What's your hero name?"

"WHO CARES I JUST STARTED YESTERDAY!" Saitama screamed really starting to bring up a panic.

Youmu cleared her throat, "As a witness I can say that he indeed did only sign up for the registry yesterday."

"Well, if you're a newbie I suggest you go home. You going on and acting like that would be an embarrassment to the other heroes!"

"Unless..." Tank top tiger leaned near Saitama's face with a sick grin.

"You're willing to fight me, a 6 ranked C class and make me look good." He whispered menacingly. Youmu had just about enough of his cockiness and quickly unsheathed her sword, pointing the blade near Tiger's neck in a threatening fashion. This made Saitama blink in confusion.

"And I suggest you take your arrogance levels down a notch. Even you, a mere C class could get hurt messing with the wrong person. And right now you're making a big mistake." Youmu's aura radiated off of her showing her to be scary, her ghost half showing its true nature. Tank top tiger froze in his spot visibly shaking, and quiet murmurs were starting to be brought up from the crowd. Everything stopped when an object came in contact with Tiger's head and exploded on contact. It successfully knocked him out.

Youmu's, as well as Aya's eyes widened as they were caught off guard. The crowd dispersed in a panic, the culprit standing there with his hand outstretched.

"Then I'll give you a reason to fight me!" He exclaimed and jumping up while giving a wide grin. His eyes flickered to Youmu and Aya for a moment; Youmu's eyes widened slightly.

"Hail of Carnage!"

She threw three shurikens in their directon. One heading for the girls, Youmu grabbed Aya by her shirt and dodged while the other two maneuvered into buildings.

"What the?! Hey Sonic stop that!" Saitama called watching the buildings explode. Sonic only grinned while he took out more shurikens.

"Come and make me!" He exclaimed throwing them.
War of Formation!

"Spell card! Wind Sign: Opening wind of the Tengu Realm!" Aya whipped her fan towards the shurikens making then explode in the air. She grinned as she flashed behind Sonic, this caught Sonic off guard but he was able to dodge a swift kick sent to him. Youmu came his way slashing her katana, Sonic kicked her away, forcing her to land on the ground. Sonic grinned even wider as went up against Aya, he put his training into action as he kept dodging her. She took out her camera, still intending to get a few pictures and was grinning herself.

Sonic took out his exploding shurikens, it flew in all directions. A stray car flew up from the force heading straight for a crying child. Youmu panicked inwardly as she saw the danger, even though she was a yokai, she was still half human. She wasn't about to let a human child perish. She was about to slice the car in half, until Saitama stepped in crushing the car.

"I don't have time for this!" He exclaimed making Youmu raise a brow.

"I need to find a bad guy!"

'Is he serious?' Youmu thought. She whistled over to him, her turning slightly to Sonic who was busy battling Aya. Saitama blinked, until his mouth shaped into an 'o' and he got what she meant. Just as Sonic swiped at Aya, Saitama suddenly appeared behind him.

"Tag." He landed a blow to the back of Sonic's head, it was powerful enough for him to land and create a fissure on the ground. Youmu and Aya cringed slightly. And Aya was also momentarily praising Sonic for his ability to survive, seeing at how Sonic was twitching on the ground. Youmu sheathed her weapon and her grey eyes stared at the unconscious ninja below her.

"So...do we just leave him here?" She asked with uncertainty.

"I think the police got it." Saitama pointed to several cars with flashing gathering around.

Youmu nodded, "Then there's no reason for us to be here then." She said, her eyes caught a flash. She glanced to the left seeing a familiar white, transparent figure, a butterfly that had cherry blossoms littering its trail.

Her eyes widened slightly as she turned, her body on high alert. She knew only one being who has butterflies like that.

"Yuyuko-sama?!" She cried quietly in shock, however one blink of her eyes and the butterfly was gone. She became disappointed as the butterfly came and gone, just like an illusion. The one figment of her master gone.

"Youmu!" Aya yelled at her causing her mind to snap out of its daze. She saw Aya and Saitama way ahead of her making her wonder how long she was dazed like that. She ran and caught up with them both.

"What happened with you?" Saitama asked, even though he sounded disinterested.

"Nothing...just thought I saw something familiar." Youmu mumbled her eyes casting glances where the butterfly once was.
