Today I got up later than usual and discovered that Ageha had prepared breakfast.
Although its taste was honestly weak, I could eat it without trouble, and it was obvious that she had learned how to cook.
I can't remember a single time when she showed any reaction to food, whether it was sweet or sour. I thought that she either didn't care about taste at all or had no sense of taste to begin with.
Moreover, both the volume and frequency of her meals are rather low, and sometimes she can go without food for a whole day, so I thought that maybe the action of eating itself is much less important to her than to a human.
But now I have discovered that she understands the notion of cooking and can also handle utensils and fire.
This shouldn't be too surprising, considering that she has recently become so self-reliant that she barely needs my care most of the time.
