Yanaike sighed as she returned to the couch, seating herself down on it. She never really liked talking about her magic with strangers, especially not in this setting. Even though she felt her apartment was pretty safe, she was unsure if people were able to overhear their conversation and what the consequences would be.
However, as much as she liked to deny it, it wasn't possible to ignore the subject anymore. Nevi knew too much already, and even though Yanaike might be able to ignore his question, she was sure he would ask another question sooner or later. She didn't blame him either. He just seemed curious. And it seemed logical to her. Yanaike would be curious herself as well if she was in his situation.
"Yes, I am a witch" she responded. "And, yes, it has to do something with my tail as well." She hesitated for a moment but then decided to tell him the full story.
"In the past, I have been involved in sort of a chemistry accident. I cannot remember the full details anymore, since I was pretty young back then. But I remember how it gave me my tail and at the same time it also gave me the ability to use magic. After that, my life has never been the same anymore. I became the victim of bullies, as where I originate from, it is pretty rare to have access to magic animal characteristics, but as you might know it is even more uncommon to have animal characteristics. This was one of the reasons I walked away from home. Since that time I have led a pretty nomadic existence, traveling around without a real home, surviving by means of magic. That was until I discovered my magic slowly fading away from my body. My spells became less powerful or at sometimes did not even have any effect at all. I don't know if it's just me, or other magicians experience this problem as well. Anyway, at the same time I discovered it had to do something with this city. Somehow I feel the cause of my magic disappearing originating from within the city walls. This is the place where my magic is still most powerful, although I hardly use any ordinary magic anymore, since I prefer to spare mana for emergencies. So, that is why I think you might be right as well. If there is indeed a illness causing people within the city walls to behave the way they do, maybe that illness is also related to my magic. But I don't know. Since I've been staying in this city I haven't made a lot of progress regarding my magic. However I have been doing a lot of experiments with magic by the use of potions. As you might know, potions are one of the most purest forms of magic and as for me, it is the only reliable source of magic right now."
