A Mosey Through Mock Town
Isao had become so distracted by the loud call of some mysterious being that He hadn't noticed that he jumped into the opening into Mock Town. He sailed through the air, looking behind him for whatever possible threat may have appeared. Was that a bird or something? Isao would not have the chance to find out, as he slammed into the back of a building's wall. The impact caused Isao to leave an imprint of his body on the wall, but it didn't look like he quite broke through. Isao looked around, attempting to get his bearings. He was lucky that he was on the back side of the building. From what he could tell, no-one had seen his accident. Brushing himself off for the second time today, Isao casually made his way down the small alleyway into the main street. What he saw next was a jaw dropping experience for him.
Before the young man was a street full of humans. They really did look like Skypians without their wings. Some were offering services while some were simply walking up and down the street. He saw a pair of humans seeming to be arguing and getting ready to fight. Some watched on with intrigue, seeming to wonder what would happen next. Isao's hand would instinctively reach up to hide the gills that were on his traps, forgetting that he was in his shinobi suit. He was careful enough to ensure that he was well covered. The average person would be unable to tell that he was a Fishman. It would be best that way. Refocusing himself, he realized that his arrival here was perfect. It meant that He could get the information that he needed. Someone had to have the information on how to get to the sky. The Knock Up Stream was surely the only way to get to the sky.
Since he had seen that there were a number of people going into the Tavern, He figured it would be the best place to start. Walking though the street, he pushed the swinging doors aside and found himself in a large room with a number of humans sitting about. Some seemed to be carrying on, enjoying their drinks, while a few seemed to look Isao over as he entered the bar. Without much thought, Isao made his way to the bartender and slapped a hand on the table. He would be grinning underneath his mask, but there was no way to tell.
"Yo, I heard that there was something called a Knock Up Stream. I figured I could take it up into the sky to find out if there is land up there. Do you know where I can find one of those things?"
Isao looked on with excitement in his eyes, whether he realized it or not. To see a human town like this, full of, well, humans, was something quite unusual for him. Luckily, no one had noticed Isao's face to the wall accident, and he attracted no attention to himself. Under the radar behavior would be good for him, given his status as a Fishman. Isao saw men and women entering and exiting a tavern on the street. The tavern was a popular one, and so it got a lot of customers. Isao quickly realized going there would make sense. Perhaps there was someone there that had some information that would be useful to him.
Entering the tavern, Isao made his way straight to the bar. What he did next, though, was surprising to say the least. Walking up to the bartender, Isao slammed his hand onto the table with excitement, asking - loud and clear - a question that was so entrenched in his mind that he could not even sleep if he wanted to.
"Yo, I heard that there was something called a Knock Up Stream. I figured I could take it up into the sky to find out if there is land up there. Do you know where I can find one of those things?"

Every last man and woman looked over at Isao with a dumbfounded look on their face. A moment of silence for the absurd question, before laughter took the tavern like a roar.
Bwahahahaha!!!
Huahahahahaha!!!
Ghahaha what an idiot!
Kuakakaka, look at this fool!
A land in the sky he said, hyahahaha!
The crowd laughed, in disbelief. Sitting at the bar over to the right was man with white hair and a tattoo covering his whole left arm.

More of this nonsense... What a moron.
The man said outloud, before turning toward Isao.
Oi, get the hell out of here you clown! We're trying to enjoy a drink here.
The man said, referring to Isao's strange getup.
Oh man, Roshio is mad at him. This won't end well...
One of the men in the crowd said.
