------------------------

A blinding heat wave.

Outside, creatures that sound like cicadas are chirping loudly.

It's been quite a long time since I came to this world. And just like in my original world, summer has finally arrived here as well.

"Ah, it's so hot..."

"It's so hot, I don't feel like doing anything..."

"Yes, just a little movement makes me sweat, and I don't feel like moving."

Noru, Estel, and I are in the living room. We're all complaining about the heat while sitting in chairs, looking listless.

Noru, in front of me, has her face on the table, looking exhausted. Estel is using wind magic from her fingertips, continuously sending a breeze throughout the room. Thanks to that, it's a bit more bearable, but it's still hot.

"Where's Sisya?"

"She was rolling around in the hallway a while ago."

"Did she attack Runa again...?"

I hadn't seen Sisya since morning, but... is she still up to that? Leaving her like this in the heat might be dangerous. I should go and check on her.

"Hey, are you okay?"

"Hahee~ Is something the matter, Ookura-san?"

"Oh, it seems she's still conscious."

"Why are you just lying here in the hallway?"

In the hallway of the house extension, Sisya was lying face down with her hands stretched out in front. When I called out to her, she responded in a lazy voice. Huh? If she can respond, it doesn't seem like Runa bit her.

"The floor here is so cool and feels nice~."

"...Your clothes will get dirty, you know?"

"I clean every day, so it's fine~."

Sisya smiled softly, rubbing her cheek against the floor, looking comfortable. Even if you clean every day, you shouldn't be lying on the floor... I understand wanting to do that in this heat, though.

As we stood there, dumbfounded, watching Sisya, my smartphone suddenly vibrated.

"Hm? This is...!?"

"What's the matter?"

"Judging by that reaction... is it a gacha?"

I took out my phone and looked at the screen. It showed, "Limited-time Swimsuit Gacha! Special items galore!"

"It's a limited-time swimsuit gacha."

A swimsuit gacha... I didn't expect there to be a limited-time gacha in this game. I don't have great memories of limited-time gacha from my original world. I remember rolling endlessly for the featured swimsuit unit that never appeared...

Looking at the details, it seems like special equipment exclusive to this gacha can be obtained. But I shouldn't go overboard... I'll just roll a few times and if I don't get anything, I'll give up.

"Swimsuits...?"

"Oh, swimsuits sound perfect for this weather. Let's roll it and then maybe go to the beach."

"Going to the beach sounds great. I'd love to have a day out with everyone."

Hearing about swimsuits, Estel and the others perked up and came closer. Even Sisya, who was lying on the floor, got up, looking very interested.

The beach, huh... The thought of the ocean in this world scares me a bit because of potential monsters. But Estel and the others seem excited, so I can't say no. Besides, the thought of seeing them in swimsuits is appealing.

"Alright, let's roll it a couple of times."

"Hehe, since it's a swimsuit gacha, I expect something cute."

Deciding to limit it to two rolls, I started the gacha. I wonder what I'll get...

I tapped the gacha, and the first roll started. A treasure chest appeared on the screen, turning silver, gold, and stopping at gold.

【R Sunscreen, SR Swimsuit 'Male', R Straw Hat, SR Swimsuit 'Female', R Beach Parasol, SR Beach Ball Set, R Barbecue Set, R Blue Hawaii, R Summer Bed, R Sunglasses, R Snorkel】

Whoa!? It's completely geared for the beach...

I tapped the gacha again for the second roll. The treasure chest appeared on the screen, turning silver, gold, white, and stopping at rainbow.

"Whoa!? For real!?"

"Wow, it's UR!"

"I wonder what it is."

To think I got a UR on the second roll! I'm amazing for getting a UR from a limited-time gacha!

【R Float Ring, SR Swimsuit 'Male', R Beach Flag, R Body Board, R Frisbee, SR Swimsuit 'Female', R Cooler Box, SR Swimsuit 'Female', R Fan, R Beach Tent, UR 'Summer Devil' Estel】

"Huh... me?"

Seeing the UR that was drawn, Estel looked surprised. What does this mean...? Let's check it out.

----------

●'Summer Devil' Estel

The outfit changes to a summer version, and a title is added.

----------

"It seems it's just a special outfit and title."

"Oh, a special swimsuit just for me? That's exciting."

Hearing it's a special outfit just for her, Estel clasped her hands together, looking delighted. It doesn't specifically say swimsuit, but since it came from the swimsuit gacha, it should be one.

"Want to switch to it right away?"

"Wait. Does that mean my current clothes will change too?"

"Probably... yeah."

"Then, let's wait until we get to the beach. I want to save the fun for then."

I was about to switch it on my smartphone, but Estel stopped me. It makes sense to save the fun for later.

***

So, we headed to the beach south of Brune. There were other people on the shore, swimming and playing in the sea. It seems there are no monsters around here.

"...It's so bright. Why do I have to come out on a day like this..."

"It would be lonely if Runa-san stayed home alone!"

"That's right. It's best to go together on such occasions."

Runa shielded her eyes with her hand, looking annoyed. Noru and the others said it would be sad to leave her behind, so we brought her along, but will she be alright? Isn't it dangerous for a vampire to be on a sunlit beach...?

"You seem to be having a hard time. Are you okay?"

"...It's fine. I'll just watch from the shade. Maybe I'll even take a nap outside for a change."

"You're going to sleep after all..."

Typical Runa. Even in a situation like this, she chooses to sleep.

"Alright, Noru and the others, let's get changed. Estel, you'll switch with the gacha, right?"

I handed the Dimension Room to Noru and the others so they could change inside. I was already wearing swim trunks under my clothes, so I just needed to take them off. Estel could switch to her swimsuit in a snap, so she could do it behind something for privacy.

"Wait, Onii-san! I'll change with Noru and the others."

"Huh? But you could switch in an instant and wouldn't have to worry about being seen."

"That's not the point. It's a tradition to change into a swimsuit and then say, 'Sorry to keep you waiting,' right?"

"Uh... yeah, I guess so."

I realized I had been inconsiderate. Estel was a bit angry, puffing out her cheeks. It’s a tradition to change into a swimsuit like that...

I handed my phone to Noru and the others and waited. In the meantime, I petted Mofuto, who I brought along.

"Hey, Mofuto. How does it look, a guy in swim trunks petting a rabbit?"

When I asked, Mofuto squeaked and snuggled up to me. It feels like it's trying to comfort me. Mofuto is a good rabbit.

After waiting for about 10 minutes...

"Ookura-dono, sorry to keep you waiting!"

Finally, Noru called out from behind. I was curious to see what she looked like in a swimsuit since she's always in a knight-like outfit with no sex appeal.

"Alright, let's see—huh?"

"Is something wrong?"

"What's with that outfit?"

"It's a swimsuit."

In my view was Noru, dressed in a white wetsuit from neck to toe. She was even wearing a black mask with a snorkel attached to cover her face. There goes all my expectations...

"Haha... I guess that's how you'd react."

"Whoa!?"

Sisya spoke up while I was stunned. Her swimsuit was a black bikini. The top crossed under her chest, naturally drawing my eyes there.

"Hehe, Ookura-san, where are you looking? Naughty~."

"I-I wasn't looking at your chest! Really!"

"You're easy to read. But I like it when you look."

She laughed, finding my reaction amusing. Damn, Sisya always enjoys teasing me. Looking at her is bad for my heart.

"Onii-san, how do I look?"

Next, Estel returned, coming to my rescue. She wore a white tube top with a black pareo wrapped around her waist. She also had a red flower ornament in her hair and a matching red scrunchie on her wrist, making her look very cute.

"Wow, it suits you. You look cute."

"Hmph, I'm happy you said that, but your reaction to Sisya was much stronger... I'm a bit dissatisfied."

Estel pouted slightly, dissatisfied with my calm reaction. But it can't be helped... I'm a man, after all, and seeing such an outfit naturally draws a reaction

. Estel's outfit is cute and wholesome, so I can appreciate it calmly.

Finally, Runa returned. Her swimsuit looked like a navy-blue school swimsuit. Why!? Why a school swimsuit!?

"...What?"

"Well, it's a classic, but..."

"This was the easiest to wear. Now, I'll go take a nap over there."

While a common type of swimsuit, is it really appropriate? Runa didn't seem to care, picking up Mofuto and walking away. She's as cool and indifferent as ever.

"Onii-san, you're quite toned without your clothes on."

"Hey, s-stop it, that tickles!"

"Hehe, it's fine, isn't it?"

While distracted by Runa, Estel came up and started touching my arms and stomach. When I told her to stop, she laughed and stepped back. It tickled because I'm not used to being touched there, and it gave me chills.

"S-so! Now that we're here, what should we do?"

"Of course, we'll swim since we have so much water here!"

With that, Noru ran into the sea. Is it okay to go in without warming up... Can she even swim? Watching her with concern, Noru happily jumped into the sea... and sank.

"Ugh, ugh... It's salty..."

"That's because you submerged the snorkel's breathing tube..."

Floundering, Noru struggled to stay afloat, her body rising and sinking repeatedly, until she eventually managed to swim back to shore. Jumping in and submerging the snorkel, of course that would happen...

After that, Noru quietly returned to the sea, this time keeping only her head above water. She's probably doing the dog paddle.

"What about Sisya...? Huh!?"

"She's running on the sea..."

I looked for Sisya and saw her running on the water. Other people on the beach were also amazed, watching her.

Hey! What is she doing!? She's drawing too much attention!

"Phew, swimming feels great."

"Swimming...? How is that swimming!? And how did you do it!?"

"Huh? I just kicked off the water with one foot before the other sank and ran."

Sisya, having run around the sea for a while, wiped her sweat with her arm, looking satisfied. What was swimming again? And she managed to do that using an old theoretical trick...

Sisya then swam normally, heading towards Noru, who was still struggling with a dog paddle. She should have swum normally from the start.

While still bewildered, I turned to look for Runa, who had gone somewhere. It didn't take long to find her...

"...What is it?"

"Nothing, but you're more relaxed than I imagined."

"Yes, it's better than I thought."

"It looks like the most mature way to enjoy the beach..."

Runa was lying under a beach parasol on a summer bed, relaxing. She had her legs crossed, wearing sunglasses, and sipping a blue Hawaii drink from a glass. Nearby, a beach tent was set up, and Mofuto was comfortably seated inside. To think the most elegant ones enjoying the beach were a little girl and a rabbit... Maybe we're doing this wrong.

"Sigh, I'm already tired and we've just arrived at the beach..."

"Oh, but Noru and the others seem to be having fun, so isn't it good?"

"Aren't you going to join them, Estel?"

"You know I'm not good at moving around, right?"

Watching Noru and the others, I felt inexplicably tired even though we had just arrived. But if they're enjoying themselves, that's fine.

Estel had been staying close to me the whole time. Now she was sitting on a sheet laid out on the beach, gazing blankly at the sea. Estel isn't very active to begin with, so if she joined Noru and the others in swimming, she'd probably tire out quickly.

"Onii-san, if you're staying with me, could you apply this to my back?"

"Huh? Sunscreen?"

"Yes, Sisya and the others applied theirs earlier, but I haven't done mine yet."

Estel took out the sunscreen from the gacha from her bag nearby. While Sisya and the others applied it themselves, Estel hadn't. Maybe she planned this... Well, if it's just applying sunscreen, I don't mind.

"Alright, I'll apply it then."

"Yes, please."

I laid Estel down on the sheet and started applying the sunscreen. When I squeezed it out, it was a white cream, so I mixed it with my fingers. I think I heard that you're supposed to mix it first. Not sure why, though.

"Mmh, ooh... ah..."

"Can you please not make those sounds?"

"I can't help it, it tickles."

As I applied the sunscreen to Estel's back, she let out strange sounds and her body twitched. It feels like I'm doing something inappropriate! I understand it's because I'm touching a spot that isn't usually touched...

"Ookura-dono, want to play beach volleyball?"

"Beach volleyball? No way."

"Why not! Let's do it!"

"Yeah, let's play!"

Just as I finished applying the sunscreen, Noru and Sisya came back from the sea, holding a beach ball from the gacha. Playing beach volleyball with Noru and Sisya... Normally, playing with girls would be fun, but with Noru and Sisya...

"Noru, I'll throw the ball up. Hit it towards the sand."

"Huh? Okay, but..."

I handed the ball to Noru and asked her to spike it. She tilted her head in confusion, but when I threw the ball up, she immediately jumped and shouted.

"Funnu!"

She then spiked the ball down into the sand with all her might. The moment it hit the sand, it made a dull thud and buried itself. As expected... The ball had a deadly force.

"...It's buried in the sand."

"See? If Estel and I joined, we'd die."

Sisya and Runa are probably at a similar level, so if we played together, Estel and I would get killed. I don't want to play murderous beach volleyball.

"Boo, boo, I guess I'll take Mofuto for a walk."

Looking dissatisfied, Noru picked up Mofuto from the beach tent and walked away.

"In that case, I'll go to Runa-san..."

"Hey, don't come here. Go run on the water by yourself."

"Aww... sniff, sniff..."

Sisya, wanting to play with Runa, approached her but was shooed away. She collapsed to her knees, expressing her disappointment dramatically. Did she really want to play that much...?

"They're so noisy..."

"Hehe, isn't it fine? This seems more fun, doesn't it?"

"Yeah, you're right."

They're a bit too noisy, but this isn't so bad. After that, we played frisbee and had a barbecue, making our first beach trip rather enjoyable.
