Some time has passed since I adopted the unknown creature, and now it is in much better condition.
It can't understand my words yet, and itself can only produce a screech that sounds like "kii, kii".
Maybe it is some kind of unknown species, or some sort of mutant human thrown away by its family, or even an alien from another planet?
In the end, I have no clues on true nature of "this".
But it obediently eats the food I give, behaves itself when I wash it, crawls around the room energetically, and doesn't make much trouble.
It seems like its body has started changing. I would rather call it "metamorphose" than "growth".
It worried me at first, but soon this creature I'm taking care of even started to look somewhat cute.
Although you can't describe its appearance any way other than "grotesque", there is something like affection between us.
That might be because its body started to resemble a human's, and its face is like a young girl's.
I've been calling her "it" and "this" for too long. Her form bears similarity to an insect, and I hope that eventually she will turn into something beautiful, so I decided to name her "Ageha".
