Things happen for a reason, either by people's decisions or by something called destiny.

If someone years ago had told me that at some point, I would be having lunch with Miura, I would not believe it. After all, I planned to have the minimum of contact with some characters.

But the girl in front of me is proof that I could be wrong.

It seems that there is a greater force that pulls the strings of life, but since it is my second life, I can't help but think that this is true.

If they asked me; If you saw Miura in danger, would you help her? My answer is obvious, I would help her without thinking. After all, I guess that spending several years with a sweet little sister made my selfish attitude decrease, it doesn't mean that it disappeared completely.

It already seems like I'm a typical romance character though if someone else were in the same situation, I'd just ignore them.

My doubts about the origin of the universe aside, I still find it hard to believe that I'm having lunch with the future fire queen of Sobu High, not that I have any complaints about it.

It's already been several days since I started having lunch together with Miura, so it could be said that one part of me got used to it while the other part thinks I'm in some kind of dream.

To think that Miura was someone so fragile and vulnerable before entering Sobu High is hard to believe. After all, one behaves according to the experiences one gains, so associating Miura with the girl I met that day in the hospital still seems unbelievable, but the proof that I'm wrong is right there in front of me, like this, that to keep trying to find the logic for this will only give me a headache.

"Raiden, do you have brothers?"

Miura question took me out of my thoughts: "I have a younger sister, she is very similar to you, except for the color of her hair." My words seemed to surprise Miura.

'' Oh, is that so?''

"I don't think I have any reason to lie to you, am I right?"

"You don't have to answer that way either" it seemed like this bothered her a bit, and she started pouting. I can't deny that she looks cute while she's doing this.

"If you want, I can present it to you, it is not that I have it hidden or anything like that.''

On second thought, I would like to know how Rumi would react to Miura. In the time at the camp in the original story, Rumi only talked to Hachiman and Yukino, as she found the other characters boring, but currently Rumi is someone different than she should be. I have no complaints about it, after all, what kind of brother wouldn't care about his little sister's future?

''¡Can I go to your house!?'' Miura's voice had a tone of excitement and nervousness at the same time.

On second thought, didn't I just invite a girl to my house?

How stupid can I be? She's nervous about it, I guess interacting most of the time in a disinterested way made me a little numb to these issues.

"If you want, it's not that I make you do it or anything like that"

I don't know why, but what I said sounded as if I was trying to trick someone into coming to my house.

"If you agree with that, I have no problem." Miura for some reason seemed happy about this, I understand this girl less and less.

Before she could respond, rang the bell that marked the end of lunchtime.

''See you at the exit Raiden'' After saying this, Miura rushed back to her classroom, she looked happy for some reason. I repeat what I think, I don't understand Miura at all.

As we drive to my house, I can't help but wonder why Rumi responded so cold when I called out to her.

Flashback

It seems that I managed to get out of school before Miura, I guess I can take advantage of this to call Rumi.

If you're wondering what kind of parents give their youngest daughter a cell phone, I'll tell you they're the same parents who almost gave her a heart attack when Rumi got lost when we went on a trip. To prevent it from happening again, they gave him a cell phone. Of course, I had to teach him the basics to use it well.

"Onii-chan are you sick? Since it's strange that you're calling me" Rumi is very insightful, even a little scary.

''Are you home already?''

"I've been here for a while, is something wrong?''

"Just a friend wants to meet you, so I'm thinking of taking her home''

Several seconds passed, but there was no response.

"Rumi, are you still there?"

"It seems I'm hearing wrong, could you repeat what you said?" For some reason, her tone became more serious than normal.

''I said she would bring a friend home since she wanted to meet you.''

I managed to hear some murmurs but couldn't understand them.

"Okay, you can bring her, after all this is your home too" After saying this, Rumi cut off the call.

End of Flashback

I guess it's nothing serious, maybe I'm thinking about it too much.

"Raiden, aren't we there yet?

''We are already close''

After a few more minutes, we finally arrived, Miura looked exhausted. Not that my house was too far, right? After all, it only takes me 20 minutes to walk.

''Is this your house? I imagined it smaller"

"I apologize to your majesty that this humble servant could not live in a more humble house" I said in a sarcastic tone. After spending several days with Miura, I can't help but be more confident, she doesn't like it being too formal.

"My mistake, will we stay here, or will you invite me in?"

''I feel comfortable right now, so I wouldn't mind staying here'' After saying this, I felt a hit on my arm, it seems like it became a habit that every time I win a conversation with Miura, she hits me on the arm. I don't understand women.

"I understand, so much violence is not necessary."

I proceeded to open the door, after which I was greeted by a ball of black hair.

"Kuro, did you miss me? I missed you too"

I was ignored by Kuro since he seemed more interested in the visit than in his owner. You hurt the heart of your owner, Kuro.

"So, this is your pet, huh, it looks really cute." Miura said, as she started to pet my cat.

"You know what they say, pets look like their owners"

"I guess it doesn't apply to this case, does it?" Miura looked quite happy after saying this, as if it were revenge for what I said earlier. I definitely cannot relate Miura to the girl I met for the first time.

''I understand. I understand, you can sit on the couch while I bring something to drink.''

With that said, Miura and Kuro went to the couch.

"Miura, are you okay with some tea, or would you like some water?"

There was no answer, this girl can sometimes have a headache.

"Yumiko, are you okay with some tea or water?"

"I'm fine with some water"

After Miura calmed down, I went to call Rumi.

"Rumi, can you come down? I want you to meet someone"

A moment later I could hear Rumi coming down the stairs.

Miura seemed excited to meet my sister for some reason.

After Rumi reached the room, she looked at Miura with a somewhat defiant look.

"I'm Tsurumi Rumi, nice to meet you" Her words were quite serious, I can't understand the reason for her attitude.

"Nice to meet you, Rumi-chan, I'm Miura Yumiko, but you can call me Yumiko"

"I'm sure I didn't give you the confidence to call me by my first name." Her words seemed to discourage Miura.

Something is wrong with her, I know she can be a bit blunt and serious, but that's not how Rumi normally behaves.

"Rumi, that was rude, wasn't it? Yumiko was just trying to be nice." For some reason, her attitude started to bother me.

"Onii-chan can you shut up for a minute, I'm talking to Miura-san." I had never seen Rumi behave like this. She must have a reason for behaving that way, so I will choose to watch this situation unfold.

"Answer me something, Miura-san, what is the relationship you have with my brother?"

After hearing this, Miura seemed to regain the confidence that he lost.

"Raiden and I are friends."

''And how can you prove that exactly?''

"I do not understand your question." I agreed with Miura, what exactly did Rumi mean by showing friendship?

"Let me put it simpler, how do I know you are not using my brother?"

"I think I'm old enough to choose my friends, Rumi." After saying this, I could see how Rumi was looking at me, as she was telling me to shut up.

Miura looked thoughtful as if she was choosing her next words very carefully.

"If you think that I associate with Raiden for convenience or things like that, let me tell you that you are very wrong, after all, I could not do that. Raiden is a special person to me, he is someone who helped me when I had problems, someone who helped and advised even though I never asked, someone I enjoy talking to, someone I would be determined to help even if I didn't ask for help.''

I was surprised by Miura's words. I think she thinks too much of me, although I will not deny that I enjoy the hours we have lunch together or when we talk while we go to her house.

These words seemed to cheer Rumi, she had a smile on her face.

"You are approved" Rumi said in a cheerful tone.

''Was it some kind of test?'' Miura asked, I also thought about it what was the need for Rumi to test Miura?

"Knowing how clueless my brother can be, I could end up being used by other people for their convenience, so I wanted to test you to see if you were someone who wouldn't take advantage of my brother."

A part of me felt happy for these words, after all, Rumi cares about me, while on the other hand, I feel insulted. It's not like I'm someone who can be easily fooled, nor am I someone who can be intimidated or anything like that.

"Rumi, your onii-chan is not someone who can be easily fooled, after all, your brother is someone wise and very trustworthy" I said it intending to show that Rumi is wrong in thinking that I am someone weak and disoriented.

Rumi motioned for me to kneel.

Following her instructions, I got down on my knees she started patting my head like some kind of animal. "Of course, you are someone trustworthy onii-chan, you are someone wise and responsible." She could feel the sarcasm in her words as if she thought I was innocent and naive.

Rumi-chan, your words hurt your brother's heart, but I guess I can't deny it, after all, in her eyes I'm just a clumsy brother who has already hurt himself several times.

While all of this was happening, Miura watched silently, as if she was waiting for the right moment to speak.

"I can tell you that you get, along very well although it is wrong that you make your little sister worry about you, Raiden-kun." There was nothing but mockery in the way Miura said this.

Give me a break, please.

"I'd like to apologize if I sounded really rude at first, as I didn't know what your intentions were with my brother, but now that I know, I can be more at ease." Rumi's words sounded sincere.

"Don't worry, I see that you care about your brother. After all, I know that Raiden can be a bit stupid sometimes. By the way, can I call you Rumi-chan?''

"I'm fine with it, Yumiko-san"

This put Miura in a good mood as if she had achieved some specific goal, I don't understand this girl at all.

After Rumi's test we spent the rest of the afternoon watching some movies, while Rumi and Miura took the opportunity to chat as if they were friends who had not seen each other in a long time. They seemed to get along well; it even seemed a bit scary how quickly they became friends.

Seeing that it was getting late, I decided to accompany Miura to her house, after all, I would not let her go alone right now.

"Yumiko-san, will you come back another time?" Rumi seemed to enjoy Miura's company.

"As long as Raiden agrees, I don't see any problem. My parents come at night, so I suppose I could come a few times."

"Don't worry about Onii-chan, you can come whenever you want, you are welcome on any occasion, I think my parents would be happy that my brother has a friend as beautiful as you"

Rumi's words made Miura start to blush for some reason.

"See you later, Rumi-chan." Both girls seemed happy after their little goodbye exchange of words.

"Onii-chan, I suppose you will accompany Yumiko-san to her house, after all, I don't think you will let her go alone so late."

"I was going to do it even if you didn't tell me anyway."

After leaving my house, we decided to take a train to Yumiko's residence.

It was already late, so it might be dangerous for two 15 year old students to walk right now. Of course, nothing would happen because the first one who tried it would end up in a deplorable state.

After leaving the station, we walked for a few minutes until we reached Miura's house. After saying goodbye, I decided to walk back as I enjoy walking.

Although the day did not go as expected, I cannot deny that I did not enjoy it. I'm happy for Rumi and Miura, I never thought they would get along so well, I guess having a similar personality helped a lot.

With these thoughts, I continued on my way home.
