"Since the monsters are underwater... I won't be able to fight the sharks because... I don't know how to swim." (Ren)
I admitted honestly.
The three of them looked at me in surprise. They clearly didn't expect that I couldn't swim.
It was embarrassing to admit, but... my life was more important than trying to act cool.
If you're wondering why I never learned how to swim, it's because I always had other priorities. I never had time to relax.
I would rather spend my entire summer vacation finding a job than lazing around. Honestly, the last time I saw a swimming pool or the sea was probably in anime.
...That sounded depressing.
Let's not think about it.
And please...
Don't look at me like that. It's embarrassing.
"Then! Ren-kun, do you want me to teach you how to swim?" (Marin)
"Stay out of this, Marin. I'll be the one to teach Ren how to swim." (Ginko)
Ginko declared confidently.
"But... Ginko-san, you also don't know how to swim, right?" (Kurumi)
"Eh...?"
I looked at Ginko, only to see her avoiding my gaze.
"Well, you can teach me later. Right now, let's focus on subjugating the shark boss first. Besides, I want to fight it myself so I can level up." (Ren)
The three of them started thinking of possible solutions.
Ginko could freeze the lake, but then we'd have to dig through all the ice just to find the boss shark. It would be like scraping through a giant frozen block just to catch one fish.
As for Kurumi, she could probably kill every shark in the lake, but she wasn't confident about locating the boss. We still had no idea how deep or vast the lake truly was.
And Marin...
Honestly, I still didn't know what her abilities were capable of, so I was curious.
I looked at the sharks swimming beneath the water.
All of them were huge.
**Name:** Blue Shark
**Skills:** Bite, Swim, Water Vision, Accelerate (Underwater)
**STR:** 1,167
**AGI:** 3,801
**END:** 2,001
**INT:** 554
**MANA:** 1,209
Wow...
Their agility was almost comparable to the boss monster I fought before. Then again, they had the advantage of fighting in water.
"Now then... what should we do?" (Ren)
I muttered quietly, but Marin apparently heard me.
She giggled excitedly, her face practically screaming, *Finally, it's my turn!*
"Hehehe! Since you need my help, Ren-kun, I'll lend you a hand and show you my amazing cosplay!" (Marin)
She said proudly.
...She was kind of cute.
"A-Alright, that would help a lot. Just don't kill the boss." (Ren)
"Then leave it to me!!!" (Marin)
"Who are you cosplaying as, Marin?" (Ginko)
"Ara~ I'm curious too. Just like when Ren-san performs a summon." (Kurumi)
"Hmmm... someone who's really good at controlling water." (Marin)
Marin walked toward the lake, her feet floating slightly above the ground.
Then she activated her skill.
"[Perfect Imitation]."
A bright light covered her body.
After a few moments—
"Now I'm done! Let's do this!" (Marin)
When I looked at Marin again, her entire appearance had changed.
Her doll-like features became more refined and elegant. Her blonde hair turned into flowing silver-blue hair, while her eyes resembled a deep blue ocean.
She wore a modified school uniform mixed with elegant knight armor decorated with blue sapphires and golden linings. A sky-blue skirt and white stockings completed the outfit.
She gave off the aura of a graceful knight.
Then she proudly posed.
"What do you think!? Kurumi-san, Ren-kun, Ginko-sama! It looks good, right!?" (Marin)
Yeah...
Forget it.
Marin would always be Marin.
"It suits you." (Ren)
I complimented her honestly.
"Well... it's not bad." (Ginko)
"I see... You're cosplaying as Umi-san, right?" (Kurumi)
"That's right! Hehehe... But it's still difficult for me to imitate all of her skills." (Marin)
"Well, naturally. Even after all the times I taught you, you still can't imitate my Ice Throne properly." (Ginko)
"*Chuckles* Well then... let's not waste any more time. Go wild, Marin-san." (Kurumi)
"Then watch me!" (Marin)
Suddenly, water gathered into the shape of a rapier in her right hand.
Without hesitation, she dived into the lake filled with sharks.
She moved incredibly fast.
No—
She was even faster than the sharks.
I could barely keep up with her movements underwater. Every time her rapier touched a shark, the creature instantly dissolved into water.
"Ah! Marin-san, don't turn the fish into water! We still need to grill them later to see if they taste good!" (Kurumi)
...Kurumi really sounded like a housewife now.
Marin gave her a thumbs-up before continuing her hunt more carefully.
Thirty minutes later—
"Hmmm... this won't work. I still can't find the boss shark, and most of these monsters aren't intelligent enough..." (Marin)
Then her eyes suddenly lit up.
"Ah! That's right! If you don't want to show yourself... then let's see about that!" (Marin)
"Ginko-sama, Kurumi-san, Ren-kun! I'm going to cast a large spell now!" (Marin)
"This girl... she only thought of that now?" (Ginko)
Ginko muttered with a dumbfounded expression.
Marin swam toward the center of the lake and quietly whispered—
"Whirlpool."
The entire lake began spinning violently.
Round and round—
Until a gigantic whirlpool formed.
The poor sharks were dragged helplessly into the raging current. No matter how hard they tried to swim away, they were continuously pulled back in.
Then—
*CRASH!*
A massive fifteen-meter blue shark burst out from the center of the whirlpool and lunged toward Marin.
Marin simply smiled calmly.
"Got you... Bubble Aquarium." (Marin)
The entire lake suddenly rose into the air, forming a gigantic floating sphere of water.
The giant shark was trapped inside.
No matter how violently it struggled, it couldn't escape.
"Ren-kun! I'll leave this one to you now!" (Marin)
"Then... leave it to me." (Ren)
"Be careful, Ren-san. Even if you're strong, you still need to stay cautious, okay?" (Kurumi)
Kurumi spoke gently while Ginko silently looked at me, waiting for my response.
"A-Alright... Thanks for worrying about me, my Kurumi and Ginko." (Ren)
I smiled warmly before briefly hugging both of them.
Honestly, I could probably kill the shark with a single bullet...
But who would refuse free hugs?
"Hey... I don't mind you three acting sweet, but could you do it later?" (Marin)
The three of us immediately separated in embarrassment.
"Sorry about that, Marin. I'll head over now." (Ren)
Then a sudden realization hit me.
Wait...
I still didn't know how to swim.
"Hey! Why are you still standing there? Ahhh, right—you can't swim." (Marin)
...Please stop reminding me.
"Don't worry about it." (Marin)
"Hm?"
"I can control your movements inside the water. And don't worry about the shark either. If anything goes wrong, I'll step in immediately." (Marin)
Honestly, I doubted the shark could kill me anyway.
I look at the shark
-- Name: Blue Shark (Boss) - -
Skills: Bite, Rapid Swim, Night and Water Vision, Ghost Body
Looking at the stats of the boss of the shark. I could tell that the shark boss was not that different to those bosses I fight before.
Then my gaze turn into the boss shark unique skill Ghost body. This must be the reason why Marin can't locate and kill it. How O. P for a boss monster, if it is a normal adventurer I doubt they will be able to kill it.
As I finish looking at the stats of shark boss. The difference in stats was obvious and even if unforseen danger encounter happen like one when the boss monster red bird queen.
I'm confident that my waifu will save me.
Yoshhh...
Let's do it then.
---
The battle ended far faster than expected.
The moment the giant shark charged at me, I threw a single serious punch.
The moment my fist collided in the shark—
The shark's massive body exploded apart from the impact.
Silence filled the water.
Even I stared at my own hand for a moment.
...I really had become this strong.
I saw the level up screen keep popping in my eyes.
At this rate being level 100 is not a far too reach now.
---
After returning to the surface, Marin guided me safely out of the water while canceling her spell.
"Yabaaa... now I'm completely soaked." (Marin)
She complained while wringing water from her clothes. Her appearance slowly turning into her normal self.
And I can see her bra showing in her wet clothes.
I quickly looked away before my two wives misunderstood anything.
"Ahem... anyway, let's head back to the safe room." (Ren)
"We're having a seafood feast tonight!"
All their eyes lit up... Since a new type of food have come.
Everyone immediately agreed.
The giant shark also dropped a blue badge, which I collected before the four of us returned to the safe room together.
And that night—
We spent our time eating grilled shark meat, talking, laughing, and enjoying the peaceful atmosphere together.
Honestly...
My life as a summoner really was peaceful.
