The Fairy's Earth

The Fairy's Earth is the episode that chronicles The Mediator's first task within her new job, following her graduation in episodes 11 and 12. It acts as the 10th episode of the anime series.

Summary
After returning to her village and meeting the locals, The Mediator moves in with her Grandpa who orders her to make first contact with the fairies in the vicinity. She finds an old scrapyard, yet is unable to find any actual fairies and returns home. She then learns that fairies are attracted to sweets and fun, so she returns the next day with a box of candies and a colorful flag. As expected, a horde of fairies is drawn towards it and she attempts to introduce herself. This scares the fairies, leaving only those trapped in the candy box. In a spur-of-the-moment decision, The Mediator ends up kidnapping them. Back home she manages to calm the fairies and befriend them, only to learn that fairies don't use names. After getting them excited about the idea of names, she chooses to assign them some and agrees to also come up with names for all their friends. When she returns to the scrapyard the next day with a number of names prepared, she discovers it has been turned into a metropolis with countless fairies. While trying to think up a solution, all the fairies line up around her waiting to have names assigned. She first tries to frighten them and run off, but has a realization and instead gives them her naming dictionary instead.

Satisfied with a job well done, she is appalled when she returns the next day and finds that the fairies have dubbed her a God and erected a statue in her honor. Knowing that this can't go on any longer, she bends down and tags Nakata, saying that he is now God instead. Frightened at the idea of being a God, Nakata tries to tag her back, only to be told that tag-backs are forbidden. As he tries to pass on the responsibility, the other fairies flee in a panic and the entire city collapses around her. Grandpa then appears in the aftermath to check on The Mediator and winds up breaking the statue of her.

Trivia

 * The episode serves as a reminder of how easily Fairies are influenced and to teach The Mediator to be careful when interacting with them.
 * Nakata reappears in episode 1, apparently having forgiven the protagonist for turning him into God. This makes him the only fairy to appear in two story arcs and the single-oldest fairy we know about.
 * This episode makes mention of The Mediator's predecessor and a diary reveals how he ate himself sick when the fairies kept throwing endless feasts for him. While Grandpa mentions that he is dead, it's uncertain if that was a result of this rampant eating.
