One day, when we were out together...a UFO overhead!? Everyone was sucked into the UFO.There are mysterious friends in the UFO. It seems that they were looking for a tsuchinoko that had strayed, and mistakenly sucked in a nearby sumikko.
Mysterious friends showed Sumikko inside the UFO as an apology. Lots of things never seen before...! "Today is a secret," said Mysterious Friends, and parted ways with Sumikko. Hope we can meet our strange friends again!
