"Congratulations, host! You have successfully defeated a king-class evil spirit, earned 5000 spirit coins, and have been promoted to Exorcism Master!"

"........"

Listening to the system's notification ringing in his ears, and glancing down at the gradually dissipating corpse of the spirit king at his feet, Hachiman Hikigaya exhaled deeply.

Previously, when he saw how powerful the king-class evil spirit was, he was still wondering what level of strength he would need to successfully defeat such a high-tier spirit. Unexpectedly, he somehow ended up leveling up without much effort...

"Congratulations on your level up!"

Rimuru, who also had a system, clapped immediately in celebration after seeing the spirit king's body turn to ashes.

After all, for the next few days, he would be Hachiman's personal human ATM, so maintaining a good relationship with him was essential if Rimuru wanted to enjoy life in the modern world.

"Well, I'm Hachiman Hikigaya. May I ask who you are?"

Coming back to his senses, Hachiman put away his Demon-Slaying Sword and started a simple self-introduction.

"My name is Rimuru, and I'm a slime~"

"A slime?!" (both said in surprise)

Hachiman and Yotsuya Miko both widened their eyes at Rimuru's answer.

"That's right, if you don't believe me, look…"

Saying that, Rimuru transformed back into its slime form on the ground.

"So cute!"

After the previous interactions and confirming Rimuru was easy to talk to, Yotsuya Miko's eyes immediately lit up seeing the jelly-like creature.

"Uh..."

Rimuru keenly noticed Yotsuya's gaze.

After all, when it was in its own territory, its minions looked at it the same way.

Transforming back into human form, Rimuru moved a bit closer to Hachiman.

Compared to that dangerous woman, it felt much safer being near this junior with uniquely sharp eyes.

"So, Rimuru-senpai plans to play around in my world for a while?"

Seeing Rimuru with such a cute face approaching him, even though he knew its true form was a slime, Hachiman instinctively stepped back a little.

"That's right!"

Upon hearing Hachiman's words, Rimuru's eyes lit up just like Yotsuya Miko's.

Cola, game consoles, manga... it was impatient to get back to them!

"Alright, but I hope you'll follow the rules while playing in my world…"

Seeing Rimuru's excited expression, Hachiman naturally couldn't ask it to immediately return to its own world.

However, Rimuru's ability to scare off three god-level evil spirits just by showing up still worried him a bit.

After all, Rimuru might look adorably innocent, but if it goes out to play, troublesome people will definitely target it...

"Don't worry, once I'm in your world, I'll naturally abide by your world's rules!"

Rimuru confidently patted its chest, promising not to cause any trouble in response to Hachiman's concerns.

"Let's hope so..."

Seeing Rimuru misunderstand what he meant, Hachiman sighed but didn't say more.

In any case, he'd keep a close watch on Rimuru during its days in his world.

"Onii-chan, where did you run off to?"

At this moment, Komachi sat on a bench in a corner of the plaza.

From afar, she saw Hachiman get off a bus with a girl. But suddenly, a crowd blocked her view.

By the time she reached the bus stop, both Hachiman and the girl had disappeared...

Just as Komachi sighed about losing track of him, she suddenly noticed Hachiman coming out of a karaoke bar.

"KTV? Onii-chan would go to a place like that?!"

Seeing Hachiman come out of the KTV was shocking enough for Komachi.

But when she saw two girls following him out, she was even more stunned into silence.

"Onii-chan said he was going to that girl Yotsuya Miko's house for exorcism!"

Seeing this scene, Komachi's face flushed with anger.

She had been worried about whether Hachiman would be tricked by that woman, but he was actually taking two girls to the KTV to hang out!

Without hesitation, she stood up from the bench, put away her mask and sunglasses, and fiercely stormed toward Hachiman pretending it was by chance.

"Well then, next we'll go to Yotsuya's house to exorcise..."

Despite everything that had happened earlier, Hachiman hadn't forgotten that the purpose of meeting Yotsuya Miko today was to solve the evil spirits troubling her life.

So, standing at the KTV entrance, Hachiman apologized to Rimuru while explaining.

"Onii-chan!"

At that moment, Komachi's voice suddenly came from nearby.

Hachiman then saw the cutest creature in the world suddenly cling onto his arm.

"Komachi, why are you here?"

Looking at Komachi hanging on his arm, Hachiman showed a trace of surprise.

"Well, after you left, I made plans to hang out with friends. But one of them suddenly bailed on me..."

Wearing a troubled expression, Komachi earnestly made up an excuse.

Then she abruptly changed the topic, asking about the two girls beside Hachiman.

"Onii-chan, who are these two big sisters?"

"Hello, I'm Yotsuya Miko, your brother's friend."

Seeing Komachi call Hachiman "brother," Yotsuya immediately realized this was her future little sister-in-law.

She smiled warmly and greeted Komachi.

After hearing Yotsuya's self-introduction, Komachi immediately sized her up.

Hmm, though she was reluctant, seeing how well Yotsuya matched Hachiman, she couldn't argue...

"Well then, next is..."

Skipping the sad topic, Komachi turned her gaze to Rimuru standing at the back.

"Uh, Komachi, come here for a moment..."

Seeing Rimuru about to introduce itself, Hachiman quickly waved it off, then pulled Komachi aside to explain Rimuru's special identity.

A few minutes later, after learning Rimuru's true nature, Komachi returned to the group.

"Hello!"

Seeing Komachi come back, Rimuru's face instantly lit up with a friendly smile.

"Hello, I'm Komachi. Welcome to have fun~"

Having understood everything, Komachi was a bit surprised looking at Rimuru but could communicate normally.

After all, if something like a system had appeared, it wasn't strange to have a few guests from other worlds.

However...

Staring at Rimuru's cute face and flat chest, a doubt popped into Komachi's mind.

By the way, do slimes even have genders?
