“Kyoko! Wait!”

A familiar voice called out for the ultimate detective who was about to leave her classroom. An out of breath Makoto had ripped open the far end door of the classroom, sprinting towards her. He came to a stumbling halt next to Kyoko wheezing with his hands on his knees.

“Hah… F-Finally… Hah… Finally got a hold of you.”

He wiped the sweat off his forehead with the sleeve of his jacket.

“Do you have something you wish to discuss with me Naegi-kun?”

“Uhm… Well… I was just wondering if you… wanted to hang out. I’ve been trying to catch you after school for a while now, but you’re always already gone by the time I get to your class.”

Makoto straightened himself up as he spoke, his cheeks still red from the sprint.

“I am sorry to disappoint you Naegi-kun but I have other matters that will require my attention shortly.”

“Oh…”

The disappointment in Makoto’s voice was unmistakable. Kyoko couldn’t help but feel a little sorry for her schoolmate. He couldn’t have possibly known how inopportune his timing would have been today.

“I will be free next friday however. If you still wish to hang out by then, that is.”

His eyes lit up.

“YES!… I mean uh… Sure that would be great.”

“Good, next Friday, same place, same time then. Don't be late.”

“I won't!"

“I have to go now, goodbye Naegi-kun.”

Kyoko pushed open the door, stepped out of the classroom and made her way down the hall. She kept her guard up, making sure nobody was following her. Makoto was too nice to attempt tailing her, but better to be safe than sorry. She took a left into one of the academy’s many stairwells and made her way to the ground level. From there it was a straight shot to her destination. The ground floor girls bathroom. Before Kyoko entered she scanned her surroundings for potential stalkers one last time. Inside the bathroom, which luckily was empty, she made a B-line for the stall at the very back. To the uninitiated the toilet-less stall housed nothing more than a mop, bucket, and other miscellaneous cleaning supplies. Kyoko however confidently slipped inside and pressed down on the leftmost tile in the second to last row. The tile sunk into the wall opening a hidden door leading down another flight of stairs. The ultimate detective stepped inside, closing the secret door behind her. Dim incandescent light bulbs cast the hidden stairway in barely enough light to see the next step.

“Almost there.”

Kyoko thought as she reached the bottom. She had arrived in the school's maintenance tunnels. Following a familiar path, the detective hastily strutted through the web of tunnels until she arrived at another door. From the outside it didn’t look much different than the others she had passed on her way here. Only this one instead of bearing a physical lock had a little pad set into the adjacent wall. Kyoko produced a little round transponder from her pocket, pushing it against the pad before pressing its button. A faint beep came from the pad as the door unlocked.

Bright yet warm light welcomed her on the other side, tinting the room's white walls a soft yellow, as the concrete flooring of the hall gave way to polymer parquette. On the far end of the room the flooring was covered by foam tiles upon which a small sofa sitting in front of a wall mounted flatscreen TV as well as a line of drawers has been placed. The side Kyoko was on meanwhile had a small podium in front of a whiteboard bolted to the ground. Across from the door, a garbage disposal chute was let into the wall.

“Right on time detective.”

Turning her head to her left she saw Peko, as well as, Maki sitting on a set of school chairs awaiting their club president. Next to them stood another currently unoccupied chair.

“I apologize for the wait. I had to shake someone on my way here.”

“Don’t mind Maki Kyoko, we all know she tends to be a little wound up by the time our meetings roll around.”

Peko replied, earning a dirty look from Maki.

“Drop dead.”

“From what I have been told we are expecting a new club member anyways right? We can’t exactly start the activities without them”

The ultimate assassin scoffed, refraining from any further comments.

“Correct Peko, she should be arriving shortly.”

“Are you gonna tell us who this new face will be, detective?”

“You will find out soon enough, Maki.”

Kyoko earned herself the assassin’s second scoff of the day.

Only a couple minutes passed before, as the ultimate detective had promised, someone knocked at the door of their club room. Through its peephole Kyoko could see the silhouette of a green haired maid patiently waiting in front of the clubroom. She opened the door allowing Kirumi to step inside. The maid performed a curtsy as she addressed the room.

“I’d like to express my deepest gratitude for being allowed to join your society. It is a pleasure meeting everyone here.”

“We are just as happy to have you with us Kirumi. I assume you came prepared for the initiation ritual?”

The maid turned towards Kyoko who had already placed herself behind the podium again.

“Indeed, I must admit I am quite excited if not a little nervous.”

Despite her direct admission no trace of said nervosity or excitement was detectable in her voice or demeanor.

“As you’ve instructed I’ve put on the provided undergarments in my chambers before making my way here.”

She raised her dress exposing the massive puffy white diaper that had been concealed beneath it till now. It was a small wonder that Kirumi was able to maintain her usual posture with diapers that looked thick enough to force a giant into waddling.

“Well done. Now if you could please recite the core tenets of our society.”

“With pleasure~

Tenet One: No word of the society shall be spoken outside its confines.

Tenet Two: Each member is entitled to suggest one new member for the society which shall then be put to a vote.

Tenet Three: No member of the society shall change their own diapers.

Tenet Four: Any violation of the previous tenets is to be punished via means the other club members deem appropriate.”

“Very good. Now just one step remains before we can welcome you into our club Kirumi. I am sure you already know what I am going to ask of you.”

“I do”

The maid closed her eyes, taking a deep breath through her nose. Moments later, accompanied by a familiar hissing sound, a wet spot appeared on the front of Kirumis diaper. In less than a minute the entire front of her padding had been engulfed by wetness, tinting the now saggy and bulging padding a faint yellow. Kirumi however was far from done.

“FRHTCHCHHHHHHHHHHFRRRRRRRRRRTFRLTTTTTTTTTTTTTT”

A foreboding enormous muffled fart escaped the maid. The slightest tremor went through her hands as she pushed.

“PBLLLLLLLLLLLLRRRRRRRRRRRRRRRRRRRRRRT! BLLLLLLLLLRRRRRRRRRRRRRRRRPHHHHHHHHHH!”

The waves of mush that followed instantly doubled the size of her diaper lifting Kirumi off the ground in the process. Despite the circumstances she did not flinch, remaining calm and collected as she let her body purge its waste into her now bean bag sized diapers.

“I do hope this suffices to prove my worthiness to be a member of this society.”

Kirumi finished her performance with a slight bow towards Kyoko. The detective in turn got off her podium and stepped in front of the maid or rather her diaper which at this point had taken such proportion that its wearers crotch sat at the president's eye level. Without hesitation Kyoko sank her hand into the padding, producing a wet squelch and prompting another mild tremor in its wearers hands.

“Not too shabby…”

The detective mumbled to herself as she groped the initiates diaper.

“I am glad to hear that my performance was satisfactory. I held it all week as you instructed.”

“Pff, that load is a week's worth for you? I could do that in half a day.”

Maki’s arm dug itself into Kirumis mushy smelly rear.

“Please excuse Maki, we had to postpone our regular club activities to make time for your initiation, our little master assassin gets cranky when she has to hold herself back for longer than usual.”

Peko had also left her chair and pulled the ultimate assassin's arm out of Kirumi’s padding.

“It’s quite alright, it was quite difficult to hold this load for so long so I can only imagine what pressure Harukawa-san must be under on a daily basis.”

“You won’t have to worry about that Kirumi, your initiation is hereby complete.”

Kyoko in the meantime had taken her hand off the maids padding and was now holding up a small nondescript transponder to their newest member.

“You’ll need this to enter the club room. You can come and go whenever you please so long as you ensure nobody follows you here.”

“I understand”

Kirumi slid the transponder into her breast pocket.

“Maki, Peko, you two can get dressed for club activities. I am gonna change Kirumi and will join you afterwards.”

The two girls nodded and made their way towards the drawers in the back of the room. Kyoko meanwhile rolled out a changing mat which she rolled the poopy maid onto.

“Make yourself comfortable, this won’t take long.”

“I did not expect that I would be changed by the club president. I was fully prepared to change myself.”

Kyoko chuckled at Kirumi’s comment.

“Did you already forget the third tenet? You are a member of this society now. But don't worry you’ll have plenty of opportunities to show off your changing skills.”

The ultimate detective first undressed the maid, throwing her clothes to the side, before undoing the tapes on her diaper giving her privates a thorough wipedown and finally balling up the used diaper. After rolling it to the side she finished the change with a fresh diaper and a generous helping of talcum for Kirumi.

“Here you can wear this until we get a proper outfit put together for you.”

She handed the maid a simple forest green shirt which she immediately pulled over her head.

“Thank you for your generosity, Kirigiri-san”

“No need to keep it so formal, you are a part of this club now.”

“Of course, my apologies.”

As the maid sat herself the other club members had already returned now sporting the same thick white diapers taped around her waist. Peko was wearing a white T-shirt with a tiger printed onto the front as well as a pair of loose black sweatpants which her diapers bulged out. Maki on the other hand sported a black onesie adorned by a pattern of roses and revolvers whose snaps looked like they were barely able to contain the massive diaper she was wearing. A pacifier clip connected the red and black pacifier in her mouth to the seam of her onesie.

“Whad chu looging ad?”

The ultimate assassin mumbled from behind her pacifier.

“Oh nothing, I just thought that you looked quite adorable in that onesie.”

“Drob dead”

In the meantime Kyoko had stuffed the maids diaper down the garbage chute and was in the midst of changing into her own club time outfit.

“Alright, I think we are all ready to begin this meeting of the Hope’s Peak Stoic Society in earnest.”

The three other girls turned their heads towards their president who was now wearing a lavender colored onesie as well as a deep purple tutu that did little to hide the puffy diapers beneath. She made her way towards the podium one last time for the day.

“I hereby declare… Nfff… the 11th club meeting of our society for… Nfff… OPEN!”

Kyoko’s cheeks puffed out a little as she spoke. To Maki and Peko it was as much a que as it was Kyoko’s most obvious tell.

“FLBRLRLRLRRLRLBRBRBRLRRLRLRLRLRLLLRLRLRLRLRLTTTTT!”

The detective's diaper instantly ballooned out pushing against the whiteboard behind her. Meanwhile the girls besides Kirumi were both following their club presidents example. To her left Peko’s eyes were rolling back, a blush appearing on her face as the bodyguard let go.

“FFFFFFSSSSSSSSHHHHHHHHH!”

“Ahhhhhhhhhhhn~”

she moaned as hot pee soaked the front of her diaper causing a notable sag. To Kirumi’s right, the reaction to Kyoko’s declaration was even more blatant. Maki had popped into a squad with her hands squeezed into tight fists and a strained look on her face.

“BLBRLBBBBBLLLRRRRLRRRLRRPHHHHHHHHHHHHHHHHHHHHHW!”

The strained snaps of her onesie snapped immediately as her diaper raised the assassin off the ground and onto a beanbag of her own poop. Her strained look was replaced by a dopey drooly smile.

“Hehe…, m-makin poobies!”

Kirumi couldn’t keep her eyes off the girl's impressive messing effort. She was finally ripped out of her trance when she heard Kyoko’s voice from the side.

“Welcome to the club Kirumi.”
