"You want to get to know more about me, don't you?" -she asked him, a mischievous, almost sadistic smile began forming on her face.

And now Yorichi was left to wonder on what kind of problem did he get himself into.

It was already too late to back down thought, he didn't knew why, but he felt that here he will be treated as he should have been when he was still a kid living under his father's house, and he deep down, even if he will never awknowledge it, wanted to have a normal childhood, it didn't matter that it was already too late for that.

This time, she decided to satisfy his growing curiosity about her, because she sudently took of her kimono to reveal a weird choice of clothing under it.

Yorichi had to admit that when he first saw her striping off her kimono, he looked away in embarrasment, he knew that he needed to respect the privacy of the womans, he was no pervert.

He refused to look back, only when she assured him that it was ok, and that she still had some clothes on, was when he decided to amuse her by turning around and look back at her.

He was surprised at finding her with some clothes he never saw someone wearing before. It was a one piece of clothing that managed to cover her from below the neck, to slightly below the knees, it was open in the back thougth, and to close it, it had a ribbon, it made sure that it won't accidentaly come sliding off her back revealing the world something It must not see.

But the clothes wasn't the last thing to surprise him, because the next second, she seemed to be growing horns, some tiger like marks started appearing on her skin, and wings started sprouting from her back, ones that had bright neon purple wing folds, exactly as the ones the viewing reports said.

He practically had the reason he came to the village asking him to be her son. Definitively that is something that doesn't happen frequently, so Yorichi was frozen in his spot, he didn't knew how to react to that revelation.

Yune started laughing, Yorichi knew that she meant no harm behind that laugh, but he could not help but feel a little bit treatened by it, she was laughing like a madman about to commit the best crime of his life, or like some of the demons he encountered when they thougth he was an easy prey and used to taunt him before attacking him and meeting their demise by his sword (Me trying to describe how my laughter sound be like...)

When she finally calmed down, she looked at him fondly, a melancholic look started taking over her eyes.

"I'm gonna tell you a little bit about my past, even before I came to this country called Japan..." -she said, in this moment was when Yorichi believed that she was older than she looked.

"In a place far away, lived a girl named Yura, she was kind, carismatic and everyone loved her. She was the first person able to use magic, and she was exeptionally talented at it, when someone had a problem, they always or most of the times asked her if she could help them, and she did as they asked, every single time, she didn't had the heart to tell them no. Sometimes someone got hurt and she healed them, other ones, they had trouble building something and she helped speed up the process with her magic" -she narrated with a small smile at her face, but soon sadness took over her expression.

"But that was her mistake, she was slowly getting overwelmed by the help request she was receiving, she could not be everywhere at once, and it turned worse after That accident" -anger started showing on her face.

"That dammed accident where a lowly human tried to do something downright disgusting to her, she fought back, it was the first time she did, and it was just so the human could get away with it and even put the people against her, no one believed her, and it broke her inside. After that accident, the people continue making their request, and she still helped them, but they did not gave her the same treatment as before, they started treating her more as a tool for their use than as a human being, at one point she got too overwelmed by them that she just broke down" -she made a little pause there, and took a deep breath before speaking again.

"That was the moment when I was born. I was the representation of her negative emotions and thoughts, the desire she had to hurt the people that treated her as a mere tool at their disposal. So when one fateful night I found the perfect oportunity to get out and unleash my anger, her surpressed feelings at the world, I took it" -she continued her story.

Yorichi was not liking where it was going.

"I attacked the town that hurt her so much, thinking that once I got rid of if that she would be so much happier, I spared the life of her only friend, the only person that believed in her, as for the rest of the world, I unleashed a devastating attack with so much corrupted magic that send it into an apocalypse, after I did that, I got tired, so I went doormant in the back of her mind, not knowing that she had been concious throught the whole event. Next thing I know, she uses some sort of spell that gets her reincarnated in the future, while I get transported here" -she said, a look of regret flashing through her face.

"When I opened my eyes again, I was in a weird place I didn't recognize, I looked the same as when I called the apocalypse on my world, It was 800 years ago, I reflected upon my actions as the years passed, knowing I did wrong, but could not apologise to the lives I had taken, so I decided that I would redeem myself by adopting tormented souls that had so many regrets in life, or people suffering from expectatives placed upon them, that was the reason why I chose to adopt you" -she finished, a sad, resignated look rested on her face.

Yorichi was left speechless, from the way she worded it, this world wasn't the one she originated from, ohh, and she was never a human being since the moment she was born, she was a manifestation of the negative emotions of someone else.

He will need some time for himself before he decides to answer her, because on one point, she did some unforgivable things from where she came from, but on the other, she wants to correct her mistakes by giving happiness to the people in this world.

"I... need to think about it" -he said before getting out of the house, leaving the demoness behind, and probably her future adoptive mother.

Now I want to inform you of the origin of Yune, because it could be confusing for some of you.
What I mentioned before is her past from an original story I'm working on, that's still on planning phase. The one mentioned is the first idea I have, but it might change as I brainstorm about the plot for it.
So you could guess that this is a crossover with a book that doesn't exist yet :')
