Mentor from the Lizardkin and the Giant Killer Slug

Come to think of it, this world is full of beauties. "Ugh..." Since I don't usually walk around much, my legs were throbbing when I woke up. The soles of my feet felt swollen, or maybe the blood wasn't circulating. I tidied up my messy hair and got out of the surprisingly decent bed. People usually complain that beds are too hard or uncomfortable, but this one was better made than I'd expected—I was a little surprised. The pillow was fluffy, stuffed with feathers. The only downside was that they just provided water for washing, so I had to splash my face and hair with cold water, which felt a bit grimy. I wonder if inns with showers cost more? There are inns with bathhouses too, but the innkeeper said if a human like me went in, all hell would break loose. He was thrilled just to have me staying there, saying it might bring him good luck. The innkeeper uncle showed his hope that I'd become a regular by giving me fruit with breakfast.

I'd been worried about what fruit in this world would look like, but it was just an ordinary apple—and it tasted like one too. I praised myself for waking up early without an alarm and stepped out of the inn. All I had was a knife and my ID. There's such a thing as too minimalist.

Generous. What a saint. Is it okay to give out stuff like this? In other novels, gods are personality-broken wrecks or totally unhelpful. Our goddess must be watching me 24/7. Yesterday, I got a skill from a free limited gacha that could break limits. Honestly, my expectations and trust had hit rock bottom by then. I just laughed, thinking the constellations are real pranksters. I absolutely can't curse them—they can probably read my thoughts too.

With that in mind, I tore the Constellation Ticket.

Flirting... that means seductive behavior, right? Gender swap, harems... Are the constellations perverts? Or do they just want to see romance? No, I'm here to defeat the Maou, not build a harem.

I stared at the skill window for a while, then reality hit, and I plopped down on the stairs at the inn entrance. "I've got 16 skills now..." But only chicken fry and wet wipe summons are usable. Fireball didn't require chanting, which was impressive in a way, but it was just a spark that fizzled out. I couldn't figure out Time Rewind or hamster transformation. Return didn't work since the inn wasn't mine. Nothing proper except Clear Mind. If the constellations keep giving skills, things might change.

Thinking that, I entered the adventurer's guild, and it was even more crowded than yesterday. What happened? As I wondered and lingered at the entrance, eyes turned to me.

"A real human!"

"Ooh... divine power really envelops their body..."

"That's the robe priests from the All Gods Temple wear. But what's that symbol?"

All the heteromorphs had come to see a human joining the guild. Is it worth taking time out of busy schedules? I froze as adventurers surrounded me in seconds. Some looked rough, others like models. This isekai world's beauty standards were insanely high. Surprisingly, no one touched me—they just looked.

"Touch a human and the fine is how much again...?"

"Round ears, no bone in the nose—is that true?"

"They look all soft overall."

Humans are fine-worthy to touch, apparently. The old Rattling who'd mentioned divine power was even praying. Is the goddess watching me, wrapping me in divine power? Or the constellations? Either way, I hope it helps. But when will this crowd disperse? I felt like a circus lion past the zoo stage.

"Everyone! The human looks troubled! Disperse, please! Divine punishment could strike our guild!"

"Pfft, as if it'd really—"

.....All eyes turned to the cat-eared youth who'd just spoken. The adventurers scattered like fleeing rabbits without a word. The praying Rattling elder trembled, moved by the scene.

That lightning was the alert, huh. The pale Rattling receptionist asked if I was uncomfortable. "N-no, the goddess just acted on her own..."

"Eek!"

No, wrong! The goddess really did it herself! In usual fantasy novels, they dump everything on the hero right after summoning! Does she seriously watch my every move live? ...Thinking about it, she summoned me and asked me to save the world—of course she'd watch! It's different from novels. This is the responsibility of someone in the god's seat...?

"I-I've never seen divine punishment in my life..."

The trembling Rattling receptionist took a deep breath, slapped her cheeks with both hands, and regained her composure. "Gods won't punish for trivial things, so it won't happen to me."

"Of course."

If anything, I'd love a lightning skill... Anyway, following her, I tore the new Constellation Ticket.

"..." U-useful...? No, there might be a use! But if pickpocketed, ID's gone...? How does it work? Detects fallen items? Can't test by dropping stuff, so I'll remember it.

"Besikyuu, this the kid?"

"Watch your mouth, Po'runga—god just dropped lightning!"

"If I did nothing wrong, no lightning."

The green short-haired woman shrugged nonchalantly. At least 180cm tall, I had to look up. Red eyes, lizard tail curled like a chameleon's at the end. But the standout was her blatantly exposed chest. Leather gloves and gauntlets on arms, leather outfit covering shoulders—but chest fully bare. Massive, head-sized breasts on display. Her abs had X-crossed straps tightening the outfit. What do you even call this attire?

I scanned the giant bombshell up and down in shock, and the receptionist clapped. "First time seeing a Deinous?"

"Y-yeah... the breasts..."

I pointed at the bare skin. She gave a troubled look, understanding the shock, coughed, and explained politely while eyeing the adventurer's outfit.

"See the scales on her chest and cheeks, and the lizard tail? Tails vary, but scaled races are Deinous. Like how rat-eared ones are Rattlings."

Races have subtle differences, but even with elf or Rattling ears, scales make Deinous, she said. Or check innate racial skills—claim desired race if multiple, usually one. "So I could say Levitfoot?" Shocking classification. Up close, scales covered the chest—no usual features.

"It's just an air sac. Like an air pocket for breath attacks."

"Breath?! From the mouth?!"

"Mine's just wind, but my dad shot lightning."

Not fire, lightning...? Air sac for lightning how? Staring in awe, she shoved her chest at me: "Touch if you want."

"N-no thanks."

"That shocking for humans?"

"Even I was stunned first time. Humans and Rattlings think breasts feed babies—not shoot fire or lightning."

The receptionist slapped the balloon-like chest: "It's springy." Mesmerizing bounce. Real-life jiggle.

Understanding my shock, she handed me ice water: "Late intro—Rokuka Besikyuu, Trust Union branch receptionist."

I sipped and nodded—nice name. Then she introduced her tall acquaintance.

"Po'runga, Deinous as you see. C-grade."

"Nice to meetcha, human."

She grabbed my outstretched hand and shook vigorously. Next I remember is me embedded in the ceiling. "Didn't expect you'd bounce off with a light squeeze," she apologized, bowing.

"She said total stats 30! Yours 750! That's why Deinous...!"

"Did I get lightning?! Am I lizard fry today?!"

I calmed the panicking duo. My heart hurt more from the handshake launch. Besikyuu frowned with a sigh: "First impressions ruined."

"Newbies get guild mentors for a month."

"No one else took a human request—using her academy junior, who owes me."

"Feel free to boss her around."

Is this guild okay? She patted my back—"Take care"—and I flew. Then Besikyuu exploded, gnawing Po'runga's head with her front teeth.

"Adventurers don't flaunt jobs—no need."

"Po'runga, martial artist?"

"Yup, sub bard. Gotta keep mouth busy in fights?"

Bard buffs via song, but not pro-level helpful. Hers all offensive—"Can't demo."

"Ear-drum burst usually."

"That's singing?"

"Yell from mouth—not singing?"

Packing spare clothes and knife in my cubic bag, she grabbed hers. Adventuring needs intense movement—fixed bags best. Mine sturdy enough for weapon, she shrugged.

"Bag can't be a weapon, right?"

"Drop prejudices to grow strong. My air sac looks soft—can smash goblin skulls swinging it."

I wished she'd keep prejudices. Woman drumming her breasts like instruments was mentally exhausting. Considering newbie me, easiest common job: merchant escort.

"Most adventurers guard merchants."

"From bandits?"

"Monsters? Bandits rare—legal walking materials, human traffickers hunt 'em."

Brutal isekai! No bandits near big cities even if they wanted. Monsters: wolves max, wyverns risky. "Boost income as porter, save merchants cart costs."

"Ah, why adventurers carry loads."

All F-grade like me, she said. I'm too frail for loads—basically ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠parasites ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠sticking for pay.

"Humans boost luck just by being near? I got double pay."

"...S-so mentors should line up?"

"Scared of divine punishment."

Makes sense. Didn't expect to leave Trust Union same day.

First quest: escort caravan to Cocos. Felt underwhelming—legs'll hurt tomorrow. Strolling blankly—

"Kyaaang!"

Sudden furious cat yowl. Turned—wagon-sized giant monster burst from forest, charging caravan!

"Giant killer slug!"

Eek! Too scary... Another "Kyaaang!"—nausea hit, different from before.

"U-uh. Ah."

Po'runga beside me mimed sluggishly like a clown. Most adventurers slowed slug-like, comical.

"..."

Why am I fine?

Thanks, Clear Mind..! Mental attack?! I swiftly raised the ticket. Novels give OP skills in crises!

"We're fucked!"

You heard the enraged slug's roar from afar!

======================

Po'runga.

Thanks to the friend who designed the outfit.
