"What !! why my body looks younger!!" I'm screamed. I woke up in a luxurious unknow room. "What's wrong, young master!" asked a butler with tiredness. Maybe he hurried to come to this room when he heard me scream.

"Hey, can I ask you who am I?" I am asking. Butler looked surprised and asked, "Do you remember me, young master?" I shook my head. The butler shocked," Please wait for a minute, young master",and then, the butler ran out with a hurry.

After a few minutes, the butler came with two other people I did not know. It seems that the other two are husband and wife. The guy there is snow white hair and a pair of emerald green eyes while the woman has a shiny blonde hair and a pair of sky blue-eyed eyes. They wear clothes like an acient people.

Suddenly, the woman then hugged me and asked "Do you still remember me, my little Kei?". Oh, it seems my name is still Kei in this world. Then, I asked "Are you my mother, ma'am?". The woman is fixed and continues to answer "Yes, yes, I'm your mother". She cried a little when answering my question. 'Do I am too harsh?' I'm mateologist myself.

Suddenly, the man said firmly "I'll make you pay for this, Marquis Garfold!". Hmm, it seems my story is about the same as Isekai's new story. Then, it must be that 'I' experienced an accident that cause because of this Marquis Garfold person and died but my spirit came to this world as a substitute of the 'Kei' spirit. Heh, don't underestimate No 1 School, Smartest Boy!

"Then, you must be my father. I'm sorry for my discomfort that caused me amnesia." I say in formal tone. They all seem shock." Is there something wrong?", I asked.

"Well, no, but you're just a quiet person before this.",my mother said. Then my dad continued "And you're just 7 years old but you can talk to me politely".What!? I'm a 7 year old boy!? Oh sh*t!(in my mind).

"I'm honor, father" I said respectablely "But father, I have a request" I said. "Hmm? What is it? This is the first time you have a request, l'm looking forward for it" my father asked.

"Well, I want to re-study what I missed". "Of course you can, sweetie" my mother interrupted, "In fact, our own home is a library if you want to learn what you missed" my mother said. "What !? This house has a library ?!" I asked with surprise. "Of course, but you must have forgotten" my father affirms.

"Oh right! You must have forgot about yourself and your family.",mother said like she just remembered. "Then, Harley come here", my father look at the butler. then, the butler come to him. Oh, so the butler's name is Harley.

"Tell Kei again about himself and this family and I have something to do, I'll eat dinner with him at the dinner table", my father said. "Yeah, that's true. I still have something that need me to be present. So we're eating together tonight, okay! " mother looks wrong.

So, my father and mother still ARE busy people in my world. "It's okay, mom, I'll wait for you tonight!", I said cheerfully. "Okay, we go first, Kei" my father smiled. I smiled back before they left.

~ In the afternoon ~

"Well, young master, let me reintroduce Duke Carl Swiss family to you" ', said Harley's butler. After 2 hours, this family introduction session ends. Hehe, now I know that, I'm the heir to Duke Carl Swiss! The butler told me, I need to say <> to see information about myself.

I immediately went back to my room. "<>". I said it after locking the room door. "Oh man! why is my status is too low ?!" I complained.

Hmm, it's look like I need to practice my ability more. But, SERIOUSLY?! Level D for a child like me??. It's even higher than some people in the guild! Maybe because I'm the son of the former hero and the famous black mage.

Oh wait, did I forgot to tell that my father is the former hero and my mother is the famous black mage? But it's okay at least I know who they are.

I know that they are powerful, but I do not think it to this extent. My mother is weak against father but very sly against father. I should not hide something big from my mother if I still want to life..

I opened the door and walk in the hallway. I wanted to go to the library. My house had two floors and my room is in the last of the hallway. God, I will get tired even before doing anything.

From upstairs, I saw my father was talking to someone I do not know. " You means that the servant in the carraige with my son is Marquis Garfold spy?"(father)" Yes, because he is the only one that know young master whereabout that time."(worker)

Father seemed very shocked." HOW CAN YOU LET HIM ACCOMPANIED MY SON WITHOUT CHECKING HIS BACKGROUND?!". My father has turned furious." I, I'm sorry your highness." The worker said while trembling.

If you wonder why he called him ' your highness' it's because in this world, Duke is a part of royal family. Leave that to be, now I should enjoy watching this. Hehehehe.

"My son had amnesia because of your carelessness!!". My father has hold his sword. Will I see someone get killed today? I laughed devilish in my mind.

" Now, now. Please be patience your highness." Someone interfered. This guy had a long green hair and brown eyes. " Why are you stopping me, Charles?", father asked.

"This is my job as your secretary to prevent you from causing problems", the guy said. " Humph!", my father walked away. " Guards! Send him to interrogation room", ordered Charles.

The guard came and dragged the worker. Oh, it seem like it has finished. I should go to the library now.

"Hey, young master", I looked back seeing Charles is behind me right now with sharp eyes.

"Hey, young master", I looked back seeing Charles is behind me right now with sharp eyes.

"Uhh" I shuttered."What? Are you shocked, young master?" He asked. How can he be behind me in a blink?? It's impossible! Unless...

~flashback~

"Young master, in this world there are rank class for everyone" Harley said. " Like Master and Mistress, they are both S+ and S rank" He continued.

"What is the highest rank?" I asked." The most low one is F rank and the higher one is SSS+ rank" He said." Wow! The difference of rank is so big!" I shocked.

"Yes, the only person that ever reached that rank is the Demon King". Wow! That's much like I expected. " So is he still alive?" I asked. "Hmm, sadly he has gone 5000 years ago due to his illness" he continued.

" So do we has hatred towards the demons?" I asked again. But it must be right? After all, ever since I awaked, I don't even see any demon.

"Yes because they killed our king to give his heart to the ill demon king". Oh.. I don't think that they need to use the king heart to heal the demon king.

" What is the highest rank in human race?". I wanted to know since it's look like we were so weaked. " Right now the highest rank is S+ and S rank"

" The S+ rank were achieved by 2 person while the S rank was only for the Twelve Fallen Angles and your mom was one of them" He said proudly.

"Who is the other person that achieved S+ rank?". " He is your father right hand. Don't worry, you will eventually know it" He smirked.

~ End of the flashback~

" Are you done observing me?" Charles smile. " huh?!" I woke up from my pensive. " That habit of yours still doesn't change, huh? Nah, it's okay. Till we meet again, young master~" He vanished into the air.

Wait, he must be that S+ right hand of father right?!! After all, he is father's secretary. Why didn't I realised it sooner??

I walked quickly to the library. " Hello, young master. Is there anything I can help?" The cute librarian asked. Wow, I don't think we have a cute servant since I'm just being escorted by butler all the times.

"Nah, it's okay. I preferred to search for it myself" I reply informally. "Okay, you can call me if you need any help" the librarian smiled gently.

I walked to a big, golden colour book shelf. It contains about my last world knowledge and magic. As far as I know all magic aptitude was stored here.

I picked some books and started reading about them. There are darkness, holy , elemental book.

Sometimes, I asked my mother about dark magic while reading the book. I'm also asked father about light magic when he has time

~ A week passed by ~

I filled my time by reading books in the library. I even know the cute librarian name is Felicia.

" Young master, Mistress is asking for you" my reading is interrupted. " Hmm, okey. Tell mother I'll be there in a minute". Felicia nodded.

I quickly finished my last page and hurriedly went downstairs. I saw my mother was talking to a butler. Maybe a high level butler?

My mother saw me and wave her hand to me. Seems that she wanted to tell me something.
