Chapter 3

"eh?" Miyuki was confused, but she decided to answer her brother's question.

"Reincarnation huh? there isn't a lot of debate regarding the topic but isn't that the philosophical or religious concept that the non-physical essence of a living being begins a new life in a different physical form or body after biological death?"

Tatsuya nodded

"That's correct, and the soul of a human being is immortal and does not disperse after the physical body has perished. Upon death, the soul merely crosses a gate before cleansing the soul clean before it transmigrates into a newborn baby or an animal to continue its immortality. The term transmigration means the passing of a soul from one body to another after death."

"but what will happen if the soul is on the stronger side that it can withstand the cleansing?" Tatsuya asked his sister.

"then the soul will retain its memories?" Miyuki answered unsure.

"then what will happen if the memories of that soul are sealed and later to be connected to the limbic system?"

Miyuki thought for a while, then her eyes widened, and understood what her brother was trying to say.

"it seems you already got it, yes, I remember my past life memories," Tatsuya said and Miyuki covered her mouth with her hands.

"T-Then ar-" Before Miyuki finished her sentence, Tatsuya cut her off.

"That's correct, I'm still your brother, but with memories of my past life that is," Tatsuya said with a wry smile while Miyuki launch herself to him hugging him tightly.

"Miyuki?" Tatsuya tried to play it cool as he felt the soft body of his sister was pressing on his body.

"Can we stay like this for a bit?" Miyuki said as she covers her face with his chest.

Tatsuya saw this made him sigh as he could not say no to his sister even if he had gotten his memories of his past life, that is, who he was, a massive sis-con.

...

After Miyuki clams down, they talk for a bit, like school, what going to be for breakfast, and kinds of stuff.

Miyuki was curious about the identity of his brother in his past life because the way he carries himself is full of dignity and elegance compared to his past self, who is a very plain boy, but that did not matter as she still loves her brother no matter what.

'I owe my life to him, and all I have and all I am belong to him alone' she thought.

"Um. Onii-sama" she asked shyly

"Hm? What wrong Miyuki?" Tatsuya asked as she put down his tea on the table.

"Can you talk about who are you in your past life? it's just the way you carry is different, even Erika manage to spot the difference, and the way you talk is there's a certain charm that people wants to listen to you"

"Sure, I wasn't hiding it from you, but let me ask you, what do you know about Arthurian Legend?" Tatsuya said with a teasing smile.

"Arthurian Legends? Is it the body of stories and medieval romances, known as the matter of Britain, centering on the legendary King Arthur?"

"thats correct" Tatsuya smiled.

"so does that mean Onii-sama is from that era? who is it? is it a famous character?" Miyuki asked excitedly.

"You can guess if you can manage to guess my past identity. Hmm, how about I'll take you on a date?" Tatsuya gave her a teasing smile, causing Miyuki to blush and enter daydream.

"Hello? Hello? Miss Miyuki? Are you still there?" Tatsuya waved his hands in front of her.

"Ah! I'm sorry"

and Miyuki tried to guess who's identity in the past; she thought I was a noble or a knight because of the way I carry myself.

"do you give up Miyuki?" He said, with a gentle smile.

"Ugh, my date with Onii-sama..."

"we can always go on a date if you want, so don't force yourself ok?" He said as he patted her head as always she liked it.

"... if you say so Onii-sama, so can you just reveal it," Miyuki asked and Tatsuya just extended his arms, and suddenly a golden light blind him for a second, and in the hands, Tatsuya there was a very beautiful sword that cannot be matched to any masterpiece in existence and the power it's emitting is not ordinary.

"T-That sword, does that mean," Miyuki said her hands covering her mouth.

"That's correct, Excalibur, the sword of promised victory, and also my oldest partner," he said with a nostalgic smile on his face.
