This item that I picked up from Muenzuka is called "cordless handset", it seems. The Japanese term is "denwa koki", "phone child-machine".

In other words, in the outside world, there are parent-child pairings even for items.

Unfortunately, it seems this child by itself isn't of any use.

Now then, how do I sell this thing off...

Kourin, I came to hang out.♪

Hey, Marisa...

Would you like to have a child?
