In this Episode we see Ai talking to Machi about her Aguu. Then Machi in turn tries to bribe Ai by giving her one of the Aguu that she has.
For doing this Machi takes Ai to the Aguu Market. There we meet the owner/tailor “Sherlock” who apparently sews Aguu to people for a deposit.
At first Ai agrees to get an Aguu sewed to her but later on realizes that it is the wrong thing to do. So she uses the Talisman given by the grampa on Machi but is later cornered by Sherlock the tailor. Then gramps and the annoying brat come in to save Ai. It is also revealed that Gramps and the brat have special powers which they use to save Ai and beat Sherlock.
It is also revealed that there is a huge demand for Aguu and there are a lot of markets all around the world. Which suggests that there is a huge world surrounding Aguu which is unknown to most common people.Aguu seems to have a very interesting environment which i hope is explored more in the later episodes.
