Note : The events won't match from now, so I will going in details in the story. So, the story might be lengthier from now...

Recap : He got an invitation from Royal Kingdom and he dealt with Mobile Fortress Destroyer

I was wearing a pretty formal black and white dress ( I couldn't find anything related to mens ) whereas Yun-Yun and Chris were dressed in beautiful white dress ( Can't describe much again ). We had to leave tomorrow so he decided not to take on quest tomorrow. I visited wiz to get some information on the Princess since she was the one to invite us.

As usual Wiz greeted me as I entered the store, I asked her, " Do you have any idea about the princess ?", I had seriously no idea about what to expect since I am from a different world. Wiz replied in confused tone, " Yes, I know about the Princess Iris, she is a cute little girl of 12 years and is also known as ' Belzerg Stylish Sword Iris ' but why are you suddenly asking about her? ". I thought to myself, if she is only 12 years old then I could fulfil my dream of having little sister calling onee-san. Wiz said, " Hey Kazuma, what happened?", pretty confused seeing me. I replied, " Umm.. Nothing much was just wondering about you said. Princess Iris has called me for a meal tomorrow in the daytime with my party for our achievements, that's all ". My reply got Wiz into deep thoughts and after while she said, " Hmm... So I suppose you are getting pretty popular, anyways, are you gonna buy some new products which I bought?", she said while clapping her hands in excitement. I bid her farewell since, I was just here to get some information on the princess. I returned to the mansion, had a pretty normal day and hit the bed.

I was trying to fall asleep but out of curiosity and excitement about tomorrow, I just couldn't fall asleep. I was covered in thoughts like, " How will be the princess " , another one " Will I create good first impression?". These type of thoughts had covered my mind so I decided to go to the balcony to relax a bit and free up my mind, it was a full moon night which was looking pretty amazing. I decided to sit over there to gaze the moon for a while but, someone like me wo couldn't sleep me approached me , it was Yun-yun, she said," Umm... Kazuma , what happened? It's pretty late why are you still awake?". I lied to her that I was just enjoying the moon since it looked really beautiful today. We chatted with each other with a while in balcony and after getting tired, we both went back to our rooms.

It was a brand new today, today we had to go to the Capital during lunch time to meet the Princess. We got dressed, had breakfast and we asked the teleporter in our town to teleport us to the capital. But, he refused saying," I am not allowed to teleport anyone to the capital without the permission from the Capital itself ", we showed him the invitation and then he agreed to teleport us. We were outside the castle of the capital so I asked the guards about where is the location mentioned in the letter. It took us about 10 mins to arrive at the location, it was pretty big white colored noble mansion. We went inside, servants and guards bowed down to us as we were walking. I got really nervous and excited seeing this hospitality and soon entered big dinning hall. At the end of the dinning hall, a cute blonde hair child wearing white dressed with some sort of green hairband. She was looking so beautiful, I couldn't get my eyes off of her but, Chris whispered, " Princess, will get the wrong impression if you don't stop staring at her ". She was right so I stopped staring her and sat down on of the chairs.

Two blonde hair onee-sama was standing beside her. The one on left of the princess, seemed like a mage and other one on the right side seemed like a knight. Princess whispered to the on the knight on the right about something. After a bit, the knight spoke up, " Princess Iris would like to hear about how you destroyed the Mobile Fortress Destroyer which seemed impossible to be stopped ". I got up and spoke in a pretty humble manner, " I am Satou Kazuma, an mere adventurer. Princess Iris, I -", that mage spoke up, " Call her your highness, commoners don't address Princess by her name who foolish adventurer. I doubt you will just tell some lies, you are the weakest class with low stats anyways ", she said arrogantly. I tried to maintain to composure and replied, " Job doesn't matter, skills is rather important so if you pardon me then please let me continue ". That mage still seemed angry but stayed silent and the knight asked me to continue. I started telling about the incident from the beginning ( you all have read it so I don't think I should write again ) and as I was half way done. That mage interrupted me, " How can a adventurer like you, use explosion three times *staring at me*. Princess Iris, this fellow is a liar, I told you it will be a waste of time. He will be punished later ", she said all this looking at the princess. I got a bit mad as she was no respect towards me and calling me a liar even though I told me true story, I spoke up in frustration, " You are you to judge me, if you call us to insult us then pardon me, I don't care about you guys either ".

Hearing me, princess spoke for the first time, " It's true, we called to discuss about your accomplishment but, seeing your arrogant behavior was changed me mood ", she spoke in pretty disgusting manner which invoked me and I replied in an angry voice, " You will be a princess but you are still a child and that should show some respects to others, you don't even know much about the outside since you all live in the castle ". The knight charged at me to attack me which I dodged pretty easily and attacked her with my own sword making her drop the sword, seeing this the mage started chanting something ( probably to attack me, although I am not familiar with magic so I had no clue ). Yun-yun counted her magic with her light of saber saving my ass. This casual talk suddenly turned into a battle. Yun-yun was standing with me to protect me while Chris was a bit behind us. Princess shouted, " What are you guys doing, Claire and Rain put down your weapons, we didn't invite then here for a duel ", hearing her voice everyone lowered their weapons. I felt like I messed up so I spoke, " I apologized for what happened, I got carrier away seeing Rain disrespectful behavior towards my achievement. Please forgive me ", princess seemed to understand and said, " Yeah, I get it. Thanks for coming, I am sorry for our behavior as well. Looks like everything is ruined now because of that little battle so we should be heading back to the castle ". Rain ( the mage ) started chanting as a circle formed below them and we were standing close to them bidding then fair well but all of a sudden, Princess grabbed my hand and before I could think, I was standing in front of the castle with them and Iris still holding onto me.

I spoke in confusion and was a bit scared, " Did you brought me here to execute me? ", princess giggled and said, " It's not like that, I just wish to hear about more of your adventures ". Claire whispered to me, " Princess has done something wilful for the first time, please don't reject it ". It was the best thing, I myself wanted to spend time with her and she brought me with her. This is called pure luck, I celebrated in my mind. We went to her room, where she sat on the bed and I sat on the chair nearby. Rain had some work so she left us while Claire was still with us. I asked Claire, " What about my friends, they will be worried... ". Claire told me not to worry, they will be notified to return back to Axel and you will sent home safely and made me satisfied then, Princess asked Claire to leave us alone which she expected without any question. I was nervous, she is so cute and she is the princess and I am alone with her. I don't know what to do, I spoke after gaining a bit confidence, " Umm... Princess I- ", she interrupted me and said, " Just call me Iris and please tell me about all your adventures and stories ". That sentence made me regain my composure and spoke up, " Then allow me to, Iris ". I was telling about all the incidents when Claire came by and got mad at me seeing how close I was from Iris and how I was mentioning with just her name. She spoke up, " Don't get too ahead of yourself Kazuma, although she has brought you here but, you don't have any right to mention her by name ". I was about to reply when Iris suddenly spoke up, " Claire, I asked him to talk to me in a casual tone and refer to me as Iris and can you please leave us alone ". She went away as she can't go against her decision and we started to discuss.

For the next few days, I got to taste some quality cuisine, got maids and butlers to order around, lived a comfortable life in the castle. Most important, enjoyed spending time my cute little sister, oh yeah, she started mentioning me as onee-san in these days. She grow affectionate towards me which I quite enjoyed. It was pretty fun to hang around with her, I was her only friend since she doesn't get a chance to go out and play like normal kids and had to be really mature in front of anyone. But, she was just like a little kid around me. She told me how much she wishes to go out and become an adventurer like me but she is forbidden. I told them that I will go home tomorrow. Iris was looking at me like she was gonna cry after hearing me and she wouldn't let me go out of her room to sleep, she was holding on to me and asking me to spend my last night with her at least. I got into an argument about how we could get into trouble if someone saw us, she took the responsibility and I ended up laying beside her. It was pretty uncomfortable since, I haven't got any experience with any girl, though she is very young but still she is really cute and her body is so warm. We had only one pillow so she ended up putting her head on my arm while I used the pillow. She slowly cuddled up towards me, she was so close that I could literally feel her breaths on my chest. I was really nervous when she spoke up, " Onee-san don't worry, nothing will happen. I trust you, so I have no problem sleeping like this so calm down and sleep ". This little girl was trying to comfort his onee-san, she is just something else but, hearing her words did released my nervousness , I decided to put my arm around her which made her flush a bit but she remained quiet.

We fell asleep just like that, I woke up pretty early in the morning. I opened my eyes to find her still cuddled so close to me, I just let a sigh after seeing how cute she is while sleeping. I slowly got up, making sure that I won't wake her up. I sat next to her just looking her sleep peacefully next to me, I lost track of time as I was consumed by her cuteness then Claire came in to wake up the princess and got shocked seeing me sitting next to her and staring at her while she is sleeping. She shouted, " Kazuma what do you think you are doing here with the Princess? ", I replied nervously, " It's not like what you think ", she replied without wasting any time, " Then what is it? ". Iris opening her eyes , probably our small fight caused her to wake up. She looked around and spoke up, " Kazuma must have been waiting for me to wake up as he was planned to leave before the breakfast, he told me last night while telling me the stories. He must have fell asleep on the chair and was sitting here waiting for that ", Iris saved me right there and I nodded in agreement. Claire seemed to buy that and said, " Is that so? But you should have atleast wait for breakfast Kazuma, you caused misunderstanding unecessarily. I agreed to stay till the breakfast.

After breakfast, Rain came by to teleport me back while Claire and Iris was standing nearby. Claire asked me, " Are you ready to go Kazuma? Princess seemed to be really fond of you, can you give us some tips to help deal with her? ". Iris flushed a bit and I laughed and said, " I don't know why she seems to like me this much. Iris , I will come around soon to meet you, ok? ". Iris still flushed replied, " Onee-san please come back soon ", Rain asked me, " So we good to go? ". I nodded towards Iris and patted her head and said, " Don't worry Iris and Rain I know teleportation so I can go, you don't need to worry ". Rain seemed a bit surprised and said, " Very well then, goodbye ". I started chanting and they faded away and I ended outside the manison. I went inside to meet the girls who were relaxing on the couch and chatting and got happy seeing me. They asked about what happened and I told them most of the things and the I asked Chris, " I want to make a magic sword, do you know who is the best blacksmith for this purpose? ". I had this thing in my mind for a long time, I wanted to change my weapons for a long time. After the attack by Claire, this thought seemed a lot important as my sword took some damage when I tried knocking her sword. Chris was thinking for a while and replied at once, " Yes, I do know one. I heard there is an excellent blacksmith in the capital but I don't know his location. You should ask someone in the kingdom itself, they must know about it ". So, I am thinking of visiting the capital again as I want to order my weapons as soon as possible. I told them that I will be back soon as I had already set up my second teleport point, in the capital which means I can freely visit it any time. I put my teleportation point in between my stay in Iris's room as they might not let me inside the castle but, if I just manage to meet her, they won't be able to anything to me. That was my thought behind my placement of the point.

I started chanting and soon after I opened my eyes in Iris's room and saw Iris sitting on the bed and Claire sitting on the chair taking her class. If you don't know then, Claire and Rain are in charge of educating my little sister. After they both noticed me, Iris spoke up in excitement, " Onee-san you are already back? Did you came her to play with me? ". Claire also asked me, " Kazuma what's the meaning of this teleport and why do you have set your teleportation point in Princess's bedroom ". I thought of an excuse and replied, " Umm... I am here to get information about the blacksmith, I want him to forge me a magical sword . I got some information that the Royal Family knows where is the best blacksmith in the capital so I just came to ask about it. My apologies for setting my teleportation point here, I will change it later ". So after a bit of conversation, Iris decided to show me the way and lead me to the blacksmith's home. I went with her, she was holding onto my hand just like your little sister holds onto you when you go to somewhere new. We chatted on the way and after for sometime, we arrived at the destination.

I went inside and asked about what do items do I need to make the my weapon. The blacksmith name was, John. He was a pretty great man, he told me to get him some items ( secret until when I collect the weapon ). I wrote them down and teleported back to Iris's room where Claire was waiting for us. I also asked Claire that if she know the skill, Dual-Wielding and Advanced Dual-Wielding. To my surprise, Claire didn't knew it but instead my little sister did. She took out her sword and asked for Claire's sword and told me to come to the training grounds. Her sword seems like a magical sword although I didn't question it and followed her blindly. We reached the training grounds, inside the castle and Claire accompanied us then she showed me the skills. I didn't have any skill points to learn it, neither have any use so will think about learning it later. For now, it seemed like a good option to atleast have it on my menu, you know. So, after that I teleported back to the mansion , I decided to visit Wiz to order the products for my sword and also I asked her to keep this items secret and not tell it about this to anyone. Why I did that? Well, I guess, I would like to suprise them later.

I have some goals in my mind, I want to get the products required for my sword and one of the products was Goddess Eris-sama's blood so I asked all the Eris Churches about it but, sadly got no lead. So, I need to figure out a way to get my hand on her blood and I need to train my level to learn some skills which I have in mind for some time.
