CHAPTER 1 - The start of it all
"Whoa...
"W-whoa!" 
"Are you ok?!"
"No! Don't let go!" 
"Just a little longer...Hang on...!"
"I can't...Ah!"
The sea was raging as a storm crackled and the downpour was a torrent. Slammed around by waves, a Riolu hit some sharp rocks very hard, right in the torso, causing them to pass out. The waves somehow carried the riolu to a beach shore nearby. By the next morning, the Riolu tried to wake up and move, but couldn't. Their vision blurred as they went unconscious once again. 
Meanwhile, further north at the front of a guild owned by a world famous explorer named Wigglytuff, a vulpix was pacing back and forth, their heart beating a thousand miles a second
"Ok...come on Cinder...time to be a big girl...I...I can do this!"
The vulpix, Cinder, stepped on the grate
"Footprint detected! Footprint detected!"
Cinder meeped and jumped back, shaking and obviously scared 
"Ugh...I can't...What made me think I could do this..."
Cinder looked at their necklace, a stone connected to it hung nicely
"I thought bringing this would help me," Cinder sighed and teared up a bit, shaking the tears away. "I need to go clear my mind. Maybe something washed up on the beach?" Turning around, Cinder headed off toward the beach. 
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
The waves lapping against the shore, the krabby blowing bubbles into the sky, something about it all seemed to calm Cinder immensely. She always came when her fear overtook her and scared her away from her dream of being an explorer. 
"Ah...The scenary always makes my worries disappear. Even when I look around I...What...ah!" Cinder saw a riolu collapsesd in the sand, and immediately rushed over. Upon arriving Cinder shook the Riolu, before smelling stale urine. It didn't matter to Cinder, she was worried about the Riolu's condition.
"Mm...Uh...where...?"
"Ah! You're awake!" 
The riolu's eyes came into focus as he met the eyes of a Vulpix, it only took a moment for the Riolu to realize the vulpix had spoken and thus causing the Riolu to jump back only to wince in pain and slump, getting a glimpse of themself in the water.
"WHAT THE HELL HAPPENED TO ME?!" The riolu tried to stand before a hissing is heard and the riolu and vulpix looked down to see the riolu unconsciously emptying their bladder.
After a few moments where the riolu sat in the water to clean themself, and cool off, he spoke.
"My name is Aster...and as weird as it sounds, I'm a human."
"Um...Sorry but you look like a riolu..."
"Yeah...Ugh I can't remember much else...all I can recall is hitting some rocks...ah! I did feel my stomach get hit...maybe the hit did damage to my nerves...Um...Is...Is there a hospital...or a nurse?"
"Well...there is Audino...She does run a clinic type area. I can take you there, but um...Will you be ok?"
"I should be, Oh right, what is your name? It's weird talking to a pokémon but well, as it stands..."
"I guess you would be confused if you were a human, as you say. My name is Cinder. Here, I'll walk you to Audino. Maybe we can figure out more about you hehe" Cinder smiled and held a paw out, Aster grabbed the paw and got helped to his feet, his lower half wet from the water as he slowly followed Cinder, but the pain kept him from walking very easily. Cinder eventually found a good walking type stick that Aster used that helped with the walking. As they got to treasure town, many pokémon looked at Aster with worry, but eventually Cinder got Aster to Audino's clinic. A pink furret wearing glasses looked up as Cinder and Aster entered.
"Oh my arceus! What happened to him!?"
"Mr.Ace, please, I found him at the beach and he's really hurt, he needs to see miss audino and um...well," Cinder whispered to Ace "He seems to have no idea when he'll...go...we may um...want something to protect during the examination." Ace blushed a bit but given his fur color he was able to hide it.
"Right, i'll get with Audino right away, you're lucky as she's free of clients right now" Ace slithered off to get Audino, in literally 3 minutes Ace calls Aster and Cinder in, as they do Ace hands Aster a pull on type undergarment. Aster was gonna argue but Cinder saying 'beach' got Aster to blush and pull it on weakly as they went to the examination room. After a few minutes, an audino walks in.
"Hello you two, I am Miss Audino, I am the doctor. So...I'm told you got hurt and was washed up on the beach? Mind explaining what happened mister Aster?"
Aster explained how he was getting thrown around in the waves and how his stomach was badly hit and how he went unconscious and was washed up onto the beach. 
"Hmmm...I'd like to do an x-ray on you, and a CAT scan, could I do that?" 
"Ah yeah, that's fine Miss Audino." Aster was a bit nervous but knew that this would help figure out if anything was wrong or if he just needed time to heal up. 
Audino went through procedure and after about an hour of waiting she had the results. She walked in with a bit of a frown.
"So...I got your results, your body is only sore from being thrown around, nothing major...However...It's about your bladder muscles."
"What do you mean? Did something happened to them?"
"Yes...apparently the rock's impact was very strong, so strong that it basically ripped them apart..."
"So...I'm..."
"Incontinent, yes"
Aster looked down and Cinder noticed his expression and turned to Audino.
"Miss Audino? He'd need a perscription to get them easily right?"
"Well, yes Cinder, that would be it...but how will you both make money?"
"Um well...Aster...I wanted to ask you something but I haven't because i've been worried about your results the whole time...But...See I want to make a rescue team, I want to explore the world and maybe find out where this lucky charm of mine goes to...the mystery of it." Cinder showed Aster her lucky charm, a relic fragment. Aster looked at it closesly, noticing it's strange design.
"That is a strange design," Aster handed it back to Cinder. "But what does that have to do with me?"
"Well...Would you...Like to join Wigglytuff's guild with me? I think together we'd be able to pay for your 'perscription' and we'd also be able to explore." Cinder's eyes sparkled with excitement and Aster seemed to hum it over. He'd need money for the diapers, and as it stands he was broke with no experience. After a moment he nodded and smiled at Cinder. "Alright, let's do it, you and me Cinder." Cinder smiled so brightly she practically tackled Aster off the exam table. The sudden hug and jolt caused Aster to wet himself without warning, getting both to blush a bit. Audino meanwhile chuckled a bit to herself. 
"Well, if you both are heading to Wigglytuff's guild I do have a pack of diapers for Aster to wear. It's a 40 pack that should be flexible enough for exploration but absorbant enough for 3 full wettings for a Riolu of his size. I'll have the perscription written but can I ask for a favor?" Cinder and Aster looked at Audino a bit confused. "See, Wigglytuff's guild got some stuff for us, but neither Ace nor I have had time to go grab it. If you both could bring it over, i'd be very thankful and you both would get a reward of Poké"
"Poké?"
"Yeah, it's how you pay for things Aster. Man the amnesia you got along with your body being beat up must have done a number." Aster realized Cinder was covering up his 'human' past by using Amnesia, which Aster did know he had, as he barely remembered his name or past. They agreed and Audino smiled.
"Thank you, now here's the pack, you can change in the bathroom unless you need assistance."
"Ah that'll be fine ma'am, I should be able to figure this out. {I mean...I do recall having younger cousins I helped change as a human...}" Aster went in and after a tiny struggle, managed to get changed and noticed, true to Audino's word, while a bit thicker they were able to move decently well, as much as their bruised body could. He exited to Cinder and Audino waiting.
"Wow, they do fit you Aster, kind of cute" Cinder giggled warmly, no hint of Malice in her words. As Aster and Cinder headed out Audino reminded them to go get her stuff and come back.
"We will, see you in a bit Miss Audino!" With that, Aster and Cinder headed toward Wigglytuff's guild. Aster determined to figure out what happened and Cinder to join and find the truth to her treasure. This was just the start for Team Hiken!
