Raiden Pov:

Yesterday several unexpected things happened, Shiromeguri-senpai's visit and being locked up together with Yukinoshita are among these.

Although the most remarkable thing would be to find out that Yukinoshita has a kind of claustrophobia, I could not see her, but I could feel her trembling with fear, even her way of speaking became very different from how I know her.

I would never have expected that she could behave that way, but I can't judge her for it, all human beings are afraid of something, no exceptions.

Of course, in the end, I ended up destroying the door of the warehouse that had locked us in, my action was very abrupt, but at that moment I didn't want Yukinoshita to continue to be like that.

If I can put it more simply, I blame my big brother instincts, after all, no one wants to see a girl cry. Although I'm not the best one to say that.

And now that I'm thinking about my big brother role.

''I should hurry up.'' I said as I finished bathing.

Today is my cute little sister's birthday, so I was getting ready to take her to the amusement park.

The normal thing would be for us to spend it as a family, but today my parents have work, so it's inevitable that they won't be able to accompany us.

Of course, we could go tomorrow, but I'd rather have all my sister's affection for me than share it with my father.

That must have sounded too siscon.

Putting aside thoughts that would get me a restraining order. I turned off the shower and started to dry off.

As I looked in the mirror, I could notice the scar I got years ago.

I don't know what went through my mind to do something like that, as the best option would have been to push Rumi away, but in my mind there was only the idea of protecting her.

But I don't regret it. Besides, the scar looks quite manly, I can't complain.

Once I finished drying off, headed to my room.

As I was changing, I heard a notification coming from my cell phone.

''Raiden, I'm already with Hina and Yui, we'll finish doing some things and go to your place.''

After reading the message, I replied in a simple way and finished changing.

I invited Yumiko, Ebina and Yuigahama to hang out together with Rumi. This was because I let slip the topic of my sister's birthday, and Yumiko supported the idea of going all together.

And since the idea was not bad, I accepted it.

Once I had everything ready, I went down to the living room where my cute little sister was watching TV.

"Rumi, are you ready?

"Yes! She's excited, it's been a while since we've been to the amusement park, the last time was where I got her that giant Pan-san.

I walked to the kitchen and left Kuro's food served since we'll probably be back in the evening, and I don't want to leave him without eating.

After that, I went to the sofa and accompanied my sister.

''Onii-chan, shall we go?

''Let Yumiko and the others arrive.''

Women take a long time to get ready, it's really a pain in the ass.

"What do you mean?

''I forgot to tell you that Yumiko and the others would accompany us today.''

If they don't take hours to arrive.

''I see.'' Her tone of voice became monotone. Did I say something wrong? ''I'll be in my room until they arrive.'' After saying that, Rumi walked up the stairs.

How strange, I didn't expect that reaction from her. But I guess it must be nothing, so I decided to keep watching TV until Yumiko and the others arrived.

I picked up my cell phone as it was ringing, could it be a call from Yumiko?

But when I looked at the name, I knew it wasn't Yumiko.

''Hello, Nagisa.'' I greeted her. I wasn't expecting a call from her at all.

''Rai-kun, why should I be the one to call and you never take that initiative?''

''Because I have no interest in doing so.'' I said in a disinterested manner.

''You're so cruel, you don't know how many guys wish they had the chance to get a call from me.''

"Too bad for them, but I'm not interested."

''That's why I like you so much.'' She said with a seductive tone.

''So, you called me to tell me that?'' I avoid conversing or spending time with Nagisa because of this.

A year ago, my aunt came to visit together with her daughters. They live in another city. Besides that, my mother and aunt didn't get along well, but after my grandfather's death, they both settled their differences and became close. Of course, we had met before on several occasions, but they were only brief talks.

So, while my parents and uncles were chatting in the living room, we children were delegated to the bedrooms.

Katsumi and Kotori went to Rumi's room, while Nagisa came to my room.

To think it all started because I didn't treat her the way she wanted.

Flashback.

Having family visitors is a hassle, more so when parents send their children to socialize with each other.

Katsumi is somewhat approachable, although the word strange defines her better, and Kotori is like a younger sister, so I have no problem dealing with her. But the problem comes in the form of my older cousin, Nagisa.

I can describe her as a popular spoiled girl. Of course, her appearance totally helps in this, and what to say about her way of expressing herself towards others.

''Raiden, bring something to drink.'' She said while she was placidly looking at her cell phone on my bed.

''I am not interested.'' I'm reading a novel on my desk. Besides, I don't want to go downstairs.

''You should listen to your elders.''

''There's a way to ask for things, but I doubt you'll understand.'' I scoffed at her.

''What are you insinuating?!'' It seems like someone got annoyed.

''Nothing, but if you understood something, maybe that's it.''

''You don't know how many guys would go buy something to drink if I asked them.''

''That's good to know, then go and ask them to bring you something to drink. Oh that's right, they're not here, too bad, looks like if you want something, you'll have to go by yourself.''

I'm not going to let myself be bossed around by a girl, even if this one is beautiful and all, I have no reason to obey orders. And I highly doubt I ever will.

''Tch!'' She went back to her cell phone.

Once our quiet conversation ended, I returned to my novel.

''Raiden-nii, Raiden-nii.'' Another voice made me close my novel, though.

''Hello, Kotori.'' Brown hair and cute ruby eyes, she was none other than my younger cousin, she's the same age as Rumi.

Kotori approached my seat.

''Do you need anything?'' She was supposed to be together with Rumi playing in her room, so it was strange for her to come here.

''I was wondering if you could bring us something to drink. Please.'' She said while looking at me tenderly.

''Sure.'' I stroked her head.

''Wait a minute, why you just do her bidding? lolicon!''

"Who are you calling a lolicon?'' I replied.

''I don't see another lolicon in this place.'' She's very volatile, apparently.

''You should learn from your younger sister who does know how to ask for things.''

I carried Kotori in my arms.

''How about we leave your witchy big sister and go both of us.''

''Yes!'' Kotori replied very cheerfully.

I gave a teasing smile to Nagisa.

I left my room with Kotori in my arms and left her at the door of Rumi's room, since it wasn't necessary to take her with me, I just said that to annoy Nagisa.

''I'll be right back.''

After saying this, I went downstairs.

Once in the kitchen, I took out some drinks from the fridge. While I was at it, I could hear Nagisa's footsteps coming behind me. Since she couldn't get someone to do it for her, it was only left for her to do it by herself.

''It's not so bad to do things by yourself, is it?''

''Don't talk to me.'' Someone got up on the wrong foot.

My mother also went into the kitchen and put on her apron. From what she tells me in the morning, she's going to cook something special for today.

''Nagisa-chan, do me a favor, go to the supermarket to buy the missing ingredients for the grill.'' My mother said in a cheerful tone.

''I'm not in the mood for that.'' Nagisa replied, in addition, I could see out of the corner of my eye as my aunt entered the kitchen.

''Nagisa!'' Apparently, my aunt is as terrifying as my mother, as she didn't hesitate to reprimand her daughter by speaking impolitely to her sister. ''It's an order, so there's no room for refusal.''

Nagisa only lowered her head.

For a brief second our gazes met, so I gave her a mocking smile.

''That's what you deserve.''

''Raiden, accompany your cousin since there are several things, and she won't be able to do it alone.'' My mother decided to include me in the conversation.

''I'm sure she can take care of it.'' I don't want to be with her, she's already unbearable.

''Don't make me repeat myself.'' The tone with which she said this was terrifying.

''I'll go!''

I could notice a smile on Nagisa's face. She really is a pain in the ass.

I went upstairs towards Rumi's room to bring her drinks, then I went to my room to pick up what I needed to go to the supermarket.

Once I made sure I had everything I needed, I went to the living room, where Nagisa was waiting for me.

We gave each other a few brief glances before leaving.

Since the mall was far away, we had to take the train, and after several minutes, we arrived at our destination.

I grab a cart that the supermarket provides and we head to the meat section to buy everything my mother put on the list. And from what I see, this includes a lot of meat. I guess it's worth it to go shopping for everything.

Although since we left the house, Nagisa and I haven't exchanged words, of course there's no need for that either.

Once we put all the meat and vegetables in the cart, we head to the cashier to pay. But the tremendous line tells us it will take forever.

"Raiden.''

"Tell me.'' I replied while concentrating on my cell phone.

''Here.'' Nagisa gave me the money to pay.

As I was about to ask her what she was thinking, Nagisa simply headed for the exit.

''I'm not going to wait here all day, so I'll wait for you at the exit.'' She said with a smirk at me.

No point in complaining about this, so I continued to stand in line to pay.

Once I paid for everything, I took the bag and headed for the exit.

With this, all that's left is to go home.

''I told you, I'm not going with you.''

''Come on, don't play hard to get, I assure you we'll have fun.''

I recognized Nagisa's voice.

As I approached, I noticed how together she was with 2 other boys her age. Although these looked dodgy looking.

I can guess that she caught their attention by her appearance, and as Nagisa was not very courteous in responding to their attempted courtship, it gave this result.

I can intervene, but a chastisement would do her good, so I merely observed.

''I wouldn't accompany ugly men like you even if you were the last man in the world, so step aside.''

''You're very cruel with your words, but I like being insulted.'' That guy has a strange fetish.

One of them grabbed her arm, which did not seem to please Nagisa.

''Don't touch me!''

Nagisa slapped him.

This is going to get out of hand, so I decided to intervene.

Since it's one thing if it's just words, but I highly doubt that guy is happy to have been slapped.

''You're a bitch!''

That guy raised a hand to hit Nagisa back, but with my free hand I stopped him.

''I wouldn't do that if I were you.'' Even though I don't like Nagisa, she's part of my family.

''Who the hell are you?!''

I released his arm and we both stepped back.

''Raiden!'' Nagisa stood behind me, as if I was a shield.

"You can both go to hell." Nagisa stuck her tongue out at them after saying this. She can be very childish.

''Stop provoking them.'' With my hand, I gave him a little tap on the forehead with my fingers.

''That hurts.''

''You deserve it.'' I felt better about myself after doing so.

''Wait a moment!'' Apparently, they won't let us go.

One of them tried to touch my shoulder, but using my arm, I pushed him away.

''You don't think I'll let them go after they insulted me.''

Seriously, people of their kind are pure idiots.

''That's what you deserve, don't think that a beautiful girl like me would respond to the insinuations of a trash like you.'' Nagisa said while using me as a shield, seriously, this girl couldn't be worse.

This guy tried to hit Nagisa, so I tried to intercept him with my free arm, although his fist hit my face.

That's it, I'm pissed. If I didn't have enough with taking care of an idiot cousin, now an asshole makes me angry, although the good thing about this situation is that I can de-stress, since now it's self-defense.

Since this guy is an idiot, I didn't need to take him seriously, so while his arm was still stretched out towards my face, I used my right arm to grab him by the neck and move him towards me, kneeing him in the stomach, I didn't hold back, so it must have hurt.

His other friend went to help him, but after we exchanged glances, this one focused on the boy on the ground.

''That's what they deserve, pathetic, hideous, ugly...''

I tapped Nagisa's forehead with my fingers again.

''That hurts!

''Stop getting me in trouble!'' I complained.

Seriously, the way she acts reminds me a lot of her since then, even as a child, she got me into every bit of trouble she could. I'm glad she went to another city.

''Let's get the hell out of here.'' My mood improved, as I was able to release some stress.

Nagisa remained silent during the train ride.

After leaving the station, all that was left was the way home.

''By the way, Raiden, thank you for helping me.''

Her tone of voice was somewhat low, but I could hear her.

''Don't even mention it.'' Even if she's unbearable, she's my family, so I have no choice.

"By the way, does your face hurt?''

''Huh?'' Her attitude towards me had changed.

''I say this because of how you received the blow to your face.''

''I've had worse days, so don't make a big deal out of it.''

That guy's punches don't compare to sensei's punches.

''By the way, I wanted to apologize for my attitude today.''

''What did you do with Nagisa?''

''I'm apologizing, and you're joking around, you idiot.''

She started to hit me, but since there was no strength in her blows, I only received them.

''You have known, since I was a child, I got used to getting anything I wanted, even in school, this was no exception.'' I could imagine it from the way she acted. ''That's why it bothers me how you rejected me without hesitation.''

''I'm not like others who will just accept orders for the sake of it, I have my own criteria.'' I like to do things because I want to do them rather than because I'm forced to do them. Of course, my parents' orders are exceptions to this rule.

''When those boys started to become more aggressive, I was afraid for a brief second, but that's when you intervened.''

''And that's why you acted proud and arrogant when I intervened?'' If she had kept quiet, I would have avoided hitting that guy.

''It's just that, for some reason, at that moment I felt safe, like no matter what I did, nothing would happen to me.''

''I should have left you with those guys.'' I replied mockingly.

''But you didn't, even though we had argued, you still went to save me.'' Her answer surprised me.

Now I'm starting to regret intervening.

''I just couldn't leave you alone. That's all.'' I don't like the direction this conversation is taking.

''Come on, be honest. ''It's because you couldn't let those guys keep your beautiful cousin.'' Her tone of voice returned to normal.

''Think what you want.'' There was no point in continuing this conversation.

''I will, by the way, do you have a girlfriend?''

''You think I might have a girlfriend?'' I made fun of myself.

Nagisa took my free arm.

''From now on I'll be counting on you, Rai-kun.'' She said with an animated and playful tone.

Why do I feel as if I got into trouble?

End of Flashback.

Even if I want to change the past, it's impossible, so I gave up on Nagisa.

''Today is Rumi-chan's birthday, so I called her to say hello, but her tone of voice wasn't very cheerful, so I chatted with her. Seriously, you can become an airhead, but I still love you.''

''What do you mean?'' I ignored the last thing she said.

''That day we went out, Rumi told us a bit about your day-to-day life. Later we'll talk about how you've been cheating on me, but back to the topic, you spend little time with Rumi-chan, and for a younger sister, losing the attention of the one you admire, and love is tough.'' I can understand where she is going with this. ''That's why Rumi was looking forward to this day to have her beloved big brother all to herself, but instead, her stupid big brother told her that he had invited more girls to join them. How many girls are you cheating on me with?''

Leaving aside the last thing she said I guess Nagisa is right, I haven't spent much time with Rumi lately. Besides, the times I'm home, Rumi is at her friends' house, so our schedules haven't coincided lately.

What kind of big brother am I if I can't figure that out?

I really screwed up today, but I can still remedy it, even though it would be more expensive and exhausting.

With the answer in mind, it's time to do it.

''Thank you, Nagisa, I wouldn't have noticed if you hadn't told me.'' I was very clueless, more than I wanted to be.

''Don't worry, I'll always help you. By the way, since I helped you, how about showing some gratitude to your beautiful cousin?''

''Even if I don't want to, I owe you one this time.'' As long as it's not something crazy, I'll have to do it.

''A date.''

''Alright.'' I was already expecting it.

''Really, you're serious? Even though all the other times you've turned me down.''

''As I said, I owe you one.'' I could only sigh at this.

''I figured it was only a matter of time before you fell under the influence of my beauty. I already have it planned, we'll go to the beach, then to the movies, we can go to a restaurant, and maybe to top it off watch some fireworks, also ...''

''Sure.'' I'll pass on that; it sounds like hell. ''How about the 32nd of this month.''

''It's a few days away, but I guess I can wait.'' Her tone denotes that she is happy. ''Besides, if we g... Wait a minute, there's no 32bd in the calend...''

I hung up.

I'm grateful to her, but what she's asking for is more than my mental stability can take.

I proceeded to block her number, otherwise my cell phone would ring all day.

Mental note, unblock Nagisa's number later.

Putting this issue aside, I have to call Yumiko.

I looked up her contact and called her.

After a few seconds, I could hear Yumiko's voice.

''Raiden, we're already going to your place, in about 5 minutes we'll be there.''

''Actually, there is a change of plans.''

''Did something happen?''

''You could say yes, but it's a hassle to explain. So I apologize for it.''

Canceling plans at the last minute is not something well-seen, let alone if it's to girls.

''Alright, you must have a good reason for doing it, but we will still expect compensation for it.'' There was some cheerfulness in Yumiko's voice.

I guess they'll ask me to take them to the mall or karaoke or anywhere that's common for girls their age, but I have no choice.

''I already resigned myself before I called you, so you can take it for granted.''

''Why do you say that as if it's a punishment?''

''Earning the hateful gaze of the guys for being surrounded by 3 beautiful girls is exhausting, you know?'' I couldn't help but complain.

Although I already got used to receiving looks full of envy and jealousy.

''It's a small price to pay to be able to have my company.'' Her tone of voice became animated by my words.

When you're aware of someone's feelings, it's much easier to deal with this one.

''Whatever you say, Ojou-sama. Then I'll see you at school.''

''See you, Raiden.''

With that settled, all that was left was to go to the amusement park with Rumi.

Rumi Pov:

I got ready to go out today with my brother.

He's still in the shower, so I went down to the living room to watch TV until he comes out.

We haven't been spending time together lately, mostly because our schedules don't coincide much, and we tend to stay in our rooms when we get home.

So being able to be alone with him today makes me very happy.

It's not that I'm envious of Yumiko and the others, who almost always tend to monopolize my brother's attention.

Thinking about it, I manage to remember the words Kotori said to me that day.

The sound of my brother coming down the stairs brought me out of my thoughts, it's finally time to go.

I'll tell Onii-chan to get me another giant panda in the prize games. Since my Pan-san will be happy to have a friend.

I couldn't predict the words he was going to say.

I just replied in a monotone and headed to my room.

Once in my room, I threw myself on my bed and hit my pillow.

''Onii-chan, you idiot.'' As I was lying on my bed, I noticed the Pan-san that my brother gave me earlier today. This made me very happy, but my spirits are currently not the best.

I know he meant well, but I still can't help but insult him.

Come to think of it, he has changed since he met Yumiko, of course I don't mind this. Moreover, I'm glad Onii-chan has friends, but you shouldn't neglect your little sister, you idiot.

But I can't tell him that I want to go out alone with him, after all, I'm not selfish enough to ask him to cancel plans with Yumiko and the others.

While I was trying to convince myself that his decision was not so wrong, my cell phone registered a call.

Seeing the name, I realized it was my older cousin, Nagisa.

"Hi. Nagisa.''

"Hi Rumi-chan, happy birthday.''

"Thank you.''

"Is something wrong? You don't sound so cheerful, and knowing Rai-kun, he must have prepared something special for your birthday.''

I explained the situation to Nagisa since even though she is special in her own way, that day we went out she proved to me that she can act like an older sister.

''I see, seriously, Raiden may be a jerk, but he's still cute.''

''Could you stop saying that? I can hear you.'' Although she can act like a decent big sister, she's also weird in her own way.

''Don't worry, Rumi, you can trust me, I'll take care of reprimanding that idiot.''

''No need, it's not that bad either. Hello? Nagisa?''

She hung up on me.

But maybe if Nagisa talks to Onii-chan, he might change his mind, although I will feel bad for Yumiko and her friends.

Now that I remember, Kotori mentioned that as a younger sister I can be as selfish as I want, after all, it's our right.

I didn't take her words to heart, but she always does that when she comes to visit, so maybe this time I can be selfish.

I just want to spend my birthday with my brother, after all, he is the most important person.

In addition, Yumiko and the others are with him at Sobu High.

I made up my mind, just this once, I want to have my brother to myself.

I left my room and went downstairs.

But as I went downstairs, I could hear him on the phone, he was apologizing to Yumiko.

''Onii-chan, did something happen?''

I decided to ask when he finished his call.

He got up and came over to me, he started stroking my head.

''I just realized that I can be an idiot sometimes.'' Apparently, Nagisa was quicker than me.

''That's very generous of you to say some occasions.'' I teased him.

''Give me a break, I have enough things to worry about later, but for today I'll forget about all that. Then Rumi, let's go.'' He said with a cheerful tone.

''Yes!'' I replied.

The day was quite fun, we went to various attractions and played many games, my brother had no qualms about spending money as he bought me anything I asked for.

Besides, looking at my side, I can see the XXXL size Pan-san that my brother got again. This time about 2000 tickets were needed to get it, but he managed to get them, I even think he broke a machine that gave tickets according to the strength with which you hit it. Onii-chan spent a long time getting tickets from that machine.

It was a pretty exhausting day; I have no complaints as I had a lot of fun.

''Rumi, don't go to sleep, there are a few stations left to get off.''

We are on the train back, but my body feels quite tired.

''It'll only be a moment, it's still a few stations to go.'' I feel absolutely exhausted.

After saying this, I leaned on his shoulder and closed my eyes.

I opened my eyes slowly, the feeling I felt was warm and very comfortable.

My brother was carrying me on his back. It had been a long time since I had done this.

I couldn't help but smile.

Since he's carrying me, I guess I can go back to sleep.

''Onii-chan, I love you.'' Normally I wouldn't tell him this, but for today, I can at least tell him.

After saying this, I let myself get comfortable and closed my eyes.
