"Mamoru? Where are you?"

I lifted my head up from my book, hearing footsteps coming down the steps, "Here." I replied in a bored tone.

A man who stood at six foot entered the living room, wearing a pristine black suit and a sky blue button up shirt underneath with a plain black skinny tie, "Your aunt and uncle are coming over," he stated as he distractedly fixed the silver watch on his wrist with his non-dominant hand.

I tilted my head, trying to remember the woman and man who were my aunt and uncle, "The woman who gave me the toy truck?"

He laughed, seeing the slight disgust on my face, "Yes, my sister. She and my brother in law are going on a trip and we're taking care of their child."

I raised an eyebrow, "They're leaving behind a child that's barely a few months old?"

He scoffed and gave me a knowing look, "I've left you behind for a whole 24 hours and nothing happened."

I stared at him, "You are aware that I was barely one right?"

He waved a finger, "It was a few days after your birthday," he corrected.

I sighed as I leaned back into my chair, returning to my psychology book. That man with the dark black slightly wavy hair and dark eyes that sparkle with amusement, is Raiden, my father.

My new father.

I clearly died. I remember my last life clearly, but I was reborn into a whole other world, a world without a war. But with my rebirth came the death of my mother, Fuyumi. So, I decided to make child raising easier for my father, by making it seem like I'm some sort of genius.

Suddenly the doorbell rang, making my father jump, "Ooh! They're here!"

I sighed as he ran to greet them, sometimes I swear he's gay, or bi seeing how he married my mother.

As I stood up I played with my fluffy ash brown hair, dwelling on my sort of predicament.

In my past life, I was a woman, but in this life, I am a male. It could be weird going through life like this, I thought as I greeted my aunt and uncle formally, but all the worries I had had washed away with new ones as I stared at my little cousin, Ryuuzaki Sakuno.

I knew of Prince of Tennis, my old father had loved it and owned the whole series before books were burned in the streets and were deemed illegal during the war. He had just as much died when the books burned in the flames, but I had read the whole series before the law came to be. That was years ago however, I wasn't confident in my memory.

But my main concern was how I got into a manga.

"Mamo-nii!"

I turned to see a small five year old running up to me. I gave her a small smile as I picked her up, "Hey Saku, how was practice with grandma?"

Sakuno smiled and enthusiastically explained her match with the mother of Sakuno's father. I was currently at her house in Tokyo, playing tennis with the famous coach. Sakuno pulled away from me and said something about having to go potty.

I looked after the young girl wearing a small tennis skirt and a polo shirt.

She doesn't even remember her parents.

I remembered my aunt and uncle because of my adult mind, but Sakuno wouldn't be able to recognize them in a picture because they died in a plane crash coming back to Tokyo when she was just a few months old.

"Kirigaya Mamoru!"

I turned my head to see an old woman wearing a dark pink jumpsuit standing on a tennis court. She pointed her racket at me, "It's your turn!" She called, grinning as she put the racket down, "And just because you're seven doesn't mean I'll go easy on you!"

I sighed and I adjusted my tennis bands before picking up a plain black racket, "Of course, Obaa-san."

Well, I thought to myself, at least I'll have a rather calm life in this world.

I plan on updating in small chapters and somewhat frequently just to get the ball moving, this is just normal life so far.
