An unfamiliar ceiling is the first thing he saw as he opened his eyelids, it was a dim room with only moonlight entering from the transparent window on his right.
He woke up on a soft bed, with a spacious room. Perhaps due to no furniture in it, the room looks very lonely, there is nothing in the room except the shelf on his right. He then muttered.
"Where am I?"
He then recalled what just happened, as long as he remembers, he saved a girl from her death and then a Ninth Stage Celestial falling from the sky to kill him but he exchange the stone with a scroll, the Ninth Stage Celestial happily carried out the transaction and shortly after, a demon appeared out of nowhere and arriving at this point.
Waking up in an unfamiliar room.
He tried to get up from the bed but his body refused to, it looks like due to stay in bed for so long, his body becoming so numb, not even he could move his legs, having no choice, he slowly raised his upper body but he stopped as he realized that his blanket is stuck, or maybe stumble upon something, he then looked at what the cause of the problem.
It was a girl with pitch-black hair, her hand tightly hold his, her head is resting on the bed, and ends up sleeping in such a weird way.
Her facial features are beautiful, she has bangs just above her eyes, and her black hair is long and straight, if she stands maybe it would reach her waist.
Joker, no wait. Kazuya Eiyuu was likewise dumbfounded. As long as his memory serves it right, he never met this girl in his entire life yet his brain knew who she is.
According to his brain, the girl on his left is his step little sister, Kazuya Rena.
As soon as he saw her sleep soundly, an urge to pat her head grew. He's not wearing a white mask so his emotion easily gets the best of him.
Somewhat difficult, he able to move his hand and patted her head softly. Her hair is soft and it smelt of an apple fragrance. The more he pats her head the more he can't stop but as he can't show emotion to his face, he actually happy and hoping this never stops, but his face is emotionless and it affects his brain.
His happy emotion suddenly disappeared without a trace in his heart, he stops patting her and subconsciously poking her face.
"Mmm~" She let out a cute groan.
He is satisfied and looked at the outside of the window. The moon came into view, it is big and round and what's more, small white particles fell to the ground, it was a rare scene to see a full moon in the middle of winter. The scene could become a background wallpaper, well anyway, he averts his gaze from the outside to his room.
He is certain he had never seen this room in his entire life, yet his brain remembers it well that this room is his bedroom. He is confused and doesn't know where to start.
There are few theories on what is going on, he has five theories in his head but the most suitable with the situation is that he teleported to another world, there is a theory that when he went into a coma, his consciousness went into the previous world but he soon cast aside the theory, if his consciousness went into the previous world, he would realize it.
He then thinks of the other three theories, as he does it. Out of the blue, an unexpected scene happened, the moonlight that was gently entering the room, now slowly losing it. The moonlight in the room slowly became dark as if being absorbed.
A warm sensation he felt as if something entering his neck and spread out to his body, little did he know the moonlight stops emitting its light to the city and only focused on Kazuya Eiyuu.
As an effect, the moonlight became a spotlight that focuses on Kazuya Eiyuu. Kazuya likewise realized what is going on and as an outcome, his body slowly become stronger.
Become stronger doesn't mean his body could move, his body is still numb and hard to control, it looks like the binding light put an ancient formation on his body, preventing it from healing by any kinds of technique, so what the moonlight do? It activates his powers from the previous world, one by one.
And here's the thing, he doesn't want those powers to make its appearance! He only wanted to be a normal boy and a normal life, some people will find it boring but if you could control your life, it will be fun and adventurous.
His life is full of dangerous every time he has powers, whether it was to save the world or save the love ones, it will come.
The body of him in this world can't activate its power due to the soul is weakened, or rather, the owner of this body, him of another him, in a weakened state. If this went as it is, the soul will die, and if it dies, he also dies.
The original owner of this body, the soul is weakened, and that weakened soul is the reason why the body is still alive and if that weakened soul died, Kazuya Eiyuu who just teleported, or rather reincarnated to this world, will also die.
One by one, his powers came back and as if that isn't enough, his treasures and items from the previous world also pop up in his spatial space.
His little sister who soundly asleep is waking up due to pure energy of high quality circulating the surroundings and entering her body.
At first, she's confused as to why this happened, high quality of pure energy is a rare thing and it circulates the room. Also, due to the high concentrate of pure energy, it starts to condense and materialized in some area of the room, such as the wall, ceiling, and the floor, it grew crystals of many forms with the same color, which is light blue, it starts to grow and the space of the room starts to become lively, so many crystals grow in mere seconds.
The whole process is enough to make history, this very scene is the first history of a Pure Crystals grew in few seconds while on average, it takes thousands of years. At this point, she only has one person on her mind that capable of such a thing.
She changes her vision from the surroundings to her brother, Kazuya Eiyuu.
Kazuya noticed that she woke up but she looks having fun by looking around and he doesn't want to ruin that, so he closed his eyes and focus to deactivate his remaining powers from the previous world that suddenly make their epic comeback.
. . . Kazuya Eiyuu.
A few seconds later, all of his powers from the previous world are now in him, though somewhat weak, he is speechless.
Not because his powers receive a huge nerf, it was because he can't do a single thing to deactivate them! This body is limiting his action, it was like the body is a device and Kazuya using a child account, so many features were limited. His dream of becoming a normal human is right in front of his eyes. Do you think someone emotionless as he won't flip the table?
（╯‵□′）╯︵┴─┴.
The moonlight that once only focused on him is slowly back down and become as it used to be. The citizens are lively and news of the disappearance of the moonlight makes a ruckus.
He opened his eyes and looked at his little sister, the room is filled with the glow of the Pure Crystals, her eyes wide open as soon both eyes met.
Tears flowing down and she tried to hold it but those emotions were piled up in her heart for the last few years, are now can't hold any longer.
She hugged him with emotions.
"Nii-same, I'm sorry. ~sob ~ I'm sorry. If only ~sob~ I was stronger."
Kazuya received her hug can only give up and let her vent out those emotions. His expression doesn't change even a bit, if only he could smile, how wonderful would that be.
Furthermore, it's been a while since he smiled, and the thing is that he doesn't remember the last time he smiled. If he thinks it thoroughly, has he ever smile in his lifetime? Such being the case, a question appeared on his mind
'How do you smile anyway?' He asked himself. He pondered for a bit and wondering what should he do next, should he said that 'it's alright and it's not her fault' to comfort her without showing a smile? That should be fine.
He opened his mouth but no sound is made, he tried again cause it is possible due to sleeping for a length of time, his throat becomes numb and voices cant be produced, yeah that must be it.
That must be it your sister! There's no way a throat would become numb after you went into a coma for two years, let alone can't produce a voice.
