I hit "Kotatsu" with a lucky draw, so if you put it in the room, "kotatsu" is at the place where my sisters hang!

one day in the winter, when it's getting cold. I was lucky enough to win “Kotatsu”! When I left it in my room immediately, my sisters who were not always able to stay in my room were attracted to the magic of "kotatsu" and came to be in the room. When I saw the lower half of my sisters who had become defenseless by such "kotatsu", I was involuntarily raised. Insert Chi-po secretly into your sister's mako illuminated by infrared rays! I received no one of the bonfired Omako!
