Volume 5 Chapter 21 Wet Rhythms
Edited by: Kanaa-senpai
”Ngh… haah… This is just my mouth, but… it feels like an electric current is surging through my brain. I’m going crazy…”
Late spring. The setting: Takanashi Hirose-san’s room.
Inside, Kushima Koharu was taking Hirose-kun’s finger into her mouth, receiving a skill treatment.
”Haah, haah… Hibiki-chan, this… this is dangerous,” Koharu said, her breath hitching.
”I-I know, right? Just finish up quickly… look, Kirino-san is next,” Hibiki replied.
The usual members were present: Hibiki, Koharu, and Kirino. Hibiki and Koharu had already completed their treatments.
”Hirose-kun, please…… ngh, ah,” Kirino whispered.
Sitting before Hirose-kun, Kirino opened her small mouth wide and clamped down on his extended finger. She let out a series of wet, rhythmic sounds as her tongue swirled around him.
Her teeth were white and perfectly aligned. Kirino came from a wealthy family and had finished her orthodontic work long ago. As Hibiki had explained to Hirose-kun before, a full set of braces usually costs about a million yen-roughly ten thousand dollars. Even if done as a child, the cost for a perfect smile is never small.
But a woman’s pursuit of beauty knows no bounds.
Having already layered “pretty” upon “pretty” through Hirose-kun’s numerous skills, the three girls were radiating a newfound sensuality. Even Kirino, who was already considered the most beautiful girl in her grade, had been polished to a blinding brilliance.
She, too, was brimming with curiosity about Hirose-kun’s new skill. If Hibiki and Koharu had received it, then she had to as well.
She had requested the Divine Dental Restoration¹ skill, but the Recoil² was of an entirely different breed than the previous ones.
The inside of my mouth feels… good? Hirose-kun’s finger is tracing my teeth, and it’s making my head spin…
The Divine Dental Restoration skill functioned as follows:
Method: Trace the interior of the mouth with a finger.
Effect: Alignment correction, whitening, bite adjustment, tooth regeneration, breath purification, and gum health improvement.
Recoil: Body flushes for a set duration; heightened physical sensitivity.
Honestly, it wasn’t just “unbelievable.” If this skill became public, dentists would be obsolete. It was that powerful.
As with his other skills, there was a Recoil, but the fact that it was triggered orally was the problem. Right now, Kirino was feeling intense pleasure just from his finger tracing her gums.
”Auh… ngh… no, this… ahhh… Hirose-kun’s finger… it’s so… mwah… it tastes delicious…” Kirino moaned, her eyes glazing over.
At first, she had simply followed the movement of Hirose-kun’s finger, but soon she was moving her mouth instinctively, sucking and licking as if trying to draw him deeper. The wet sounds filled the room, sounding exactly like a simulated act of intimacy. The pleasure of her tongue was transmitted directly to Hirose-kun’s hand.
”Ah, Kirino’s gone over the edge too… ngh,” Hibiki muttered.
”I can’t help it… I want Hirose-kun’s finger soon, too…” Koharu added.
Watching the treatment, Hibiki and Koharu seemed to develop an oral fixation of their own. They began sucking on their own fingers, waiting impatiently for Kirino’s turn to end. A desperate urge to be licking something had completely taken hold of them.
”-Phew, that’s it. Good job,” Hirose-kun said.
”Ahh…!” Kirino let out a sharp cry of regret.
A few minutes later, when he pulled his finger away, Kirino let out a pained whimper. His finger was drenched in her saliva. He grabbed a nearby wet wipe and cleaned his hand.
”Hirose… it’s okay now, right?” Hibiki asked, stepping closer.
”Hirose-kun…!” Koharu urged.
With Kirino finished, Hibiki and Koharu pounced. They had been holding back this whole time, and their restraint had finally snapped.
”Wait, let me rest a litt-“
”No way♡” the two girls said in unison.
Hibiki stole Hirose-kun’s lips, while Koharu took his left finger into her mouth, her tongue entwining with it in a frantic rhythm.
”Then, I’ll excuse myself as well,” Kirino said quietly.
”Kirino!? That’s the-ngh!” Hirose-kun gasped.
Hirose-kun expected her to take his free right hand, but instead, Kirino was already sliding down the zipper of his pants.
”Ah… I can’t stand it… my mouth is just… begging for you, Hirose-kun…♡”
With those words, Kirino buried her face in Hirose-kun’s lap.

”Mizobe! Fifty meters left! You can still push it!”
After school. In the indoor pool adjacent to the school building, the female coach of the girls’ swim team barked out orders.
From here… the final spurt!!
The girl executed a perfect turn, kicked off the wall with power, and sliced through the water. Her arms rotated in a beautiful, efficient crawl as she surged toward the finish line. Using her height-unusually tall for a girl-her strokes were long and graceful. She was the swim team’s undisputed ace.
Tweet!!
”…Hmm. Not bad. But I know you can shave more time off that!” the coach said.
”Yes, Coach!” Mizobe replied.
As she reached the wall, Mizobe climbed onto the poolside. She pulled off her goggles and swim cap, shaking her head. Her hair, accented with blue highlights, shimmered as it scattered water droplets.

”As expected of Mizobe-senpai…!” one junior whispered.
”She’s in top form today!”
”The coach still doesn’t look satisfied, though.”
”That’s just because she expects so much from her. Mizobe-senpai is the only one in this school who can actually compete on a national level!”
-Mizobe Aya.
She was the ace of the swimming club and deeply respected by her juniors. A serious student who worked harder than anyone else at her sport. Winning at the Tokyo regionals was a given for her; she was a top-tier athlete with the national team in her sights.
But even she wasn’t perfect.
”Adah!?”
As she walked along the poolside alone, her foot caught on a kickboard left on the floor. She slipped and wiped out grandly.
”Hey, first-years! I told you to put the kickboards away properly!” the coach barked.
”W-We’re so sorry!!” the students cried out.
Even at a powerhouse school, there are always newcomers. The first-years, scolded by the coach, scrambled to gather the boards and bowed deeply to Aya. “We are so sorry!”
”Ahaha, it’s fine. Just be careful next time,” Aya said with a gentle laugh.
”Seeing her like that… it makes Senpai look kind of cute, doesn’t it?”
”Yeah, that clumsy-girl vibe is the best!”
The imperfect Aya. That side of her was another reason she was so well-loved.
* * *
”-Takanashi-kun. It looks like you haven’t turned in your career path survey yet. Is everything okay?”
Morning in the classroom. Mizobe Aya approached Hirose-kun at his desk. She was a striking girl with her blue-tinted hair and somewhat thick glasses.
Aya had poor eyesight, which was why she wore prescription goggles while swimming. But once the goggles came off, her vision was poor, making it hard for her to notice things left on the floor.
”Ah, sorry, Class Rep³. I filled it out, so here you go,” Hirose-kun said.
”Honestly. If you had it, you should have brought it to my desk in the first place,” Aya sighed.
”Ahaha… sorry. You’re so reliable, it really saves me.”
”That’s only because you aren’t reliable at all…!”
Aya snapped back with a hint of irritation, but she wasn’t truly angry. She was the Class Representative for Hirose-kun’s class. She had been the Class Rep type since she was a child and had volunteered for the role here, acting as the leader who held the class together.
She had actually intended to be the captain of the swim team as well, but the coach wouldn’t allow it, fearing the administrative duties would hinder her performance.
”Excuse me-is Hirose-senpai here?”
Standing by the classroom door were Suzumori Aoi from the basketball club and her best friend, Kozuka Rio. Aoi was waving frantically at Hirose-kun.
”…They’re calling for you, Mr. Popular,” Aya whispered.
”C-Class Rep. That’s a bit mean…”
”I’m just stating facts. Anyway, don’t keep them waiting. Go on.”
”Thanks, Class Rep.”
Hirose-kun stood up and headed toward Aoi. Aya watched him leave and whispered to herself.
”Takanashi-kun… he really is a mystery.”
She had only met him after being placed in this class. She’d noticed his skin was unusually clear, but she didn’t see any particularly masculine charm in him. And yet, girls from all over the school were constantly swarming him. It was baffling.
And she wasn’t the only one watching.
”……Tch.”
Watching Hirose-kun leave, one of the boys let out a quiet click of his tongue.
”Okada-kun, is something wrong? Hey, tell us more about the Dungeon!”
While not as mobbed as Hirose-kun, there was one other boy surrounded by girls. He was Okada, one of the few registered Adventurers in the school.

Trivia:
- Kirino’s dental work cost approx 1 million yen, highlighting her wealthy background.
- Aya has poor eyesight and wears prescription goggles, which explains her clumsy ‘dojikko’ moment.
- Aya was blocked from being swim captain to protect her performance, leading her to become class rep instead.
- Okada is a registered Adventurer, placing him in a similar ‘special’ category as Hirose, though likely through traditional means.
- The dental skill actually regenerates missing teeth, which is medically impossible

TL Notes:
Notes:
• Kushima Koharu – A reserved, literature-loving girl (F, 156cm, G-cup, black braid) who struggles with family problems, including bruises and emotional stress. She experiences dramatic physical and emotional improvements after Hirose’s skill use, revealing a hidden wild side during explicit nighttime encounters.
• Kirino – Strikingly beautiful with blue long hair (F, 168cm), Kirino is gifted with ice magic and feels isolated because of her appearance. Hirose’s Beauty skill helps her improve her self-image and social comfort, directly affecting Kirino’s relationship with her family and classmates.
• Mizobe Aya – Class Representative (Iinchou). Ace of the girls’ swim team. Tall, blue inner-color hair, wears thick glasses. Clumsy (dojikko) personality.
• Kozuka Rio – Aoi’s best friend. She has a neat, precise look with side ponytail black hair and is slightly shorter than average. She was initially friendless, making her connection to Aoi incredibly important. She is highly suspicious of Hirose and what he’s done to change Aoi, viewing him as a threat.
• Rio – A member of the Beauty Committee who previously worked with Hirose and already holds a negative opinion of him, seeing him as a ‘playboy.’ She has short dark hair and is dressed neatly in her school uniform. She is Aoi’s friend and is currently determined to ‘rescue’ her.
• Okada – Male student and registered Adventurer. Popular with girls due to his dungeon progress.
