Short Story - 恐怖のフィロリアル - The Horrifying Pilorial
After one last kick and defeating the last monster, Fitoria has cleared a wave from Dragon Hourglass guarded by the Filolial. Fitoria was entrusted by the former heroes to defend the world in their place. Fitoria remembers, that new Heroes were summoned but wonders why they haven't done anything about the coming waves yet. As she thinks, her Filolials minions return, who were tasked to return a girl home (Volume 3 side story). As Fitoria asks if the girl is safely returned, they say that they forgot to do it (Fitoria remembers that her Filolial minions have short memory). She asks what happened and they answer, that they found a monster Filolial, that is not like any, it is drool at Filolials, bigger in size, white, red and pink colored. Understanding that only Filolial raised by heroes are able to become Filolial Queen/King, Fitoria wants to meet this new Filolial Queen.

As the search for the new Filolial Queen starts, they go to a Filolial ranch to look for information. In the ranch, a Black Filolial, named Mr.Black, sees the cute Fitoria and asks her to be his harem. Fitoria gets mad, kicks him before healing him (she overdid it). As Mr.Black runs away, an old Filolial comes and apologizes for Mr.black. Fitoria asks about the new Filolial Queen, he tells her, that it's a normal Filolial Queen, but unknown where she is. The Filolial minions find out that she is heading southwest.

Continue traveling southwest, she hears a dragon shout. She finds a monster with a dragon fragment attacking a human city, defending the city is a pink Filolial Queen and a person with a shield on his back. As she sees the scene, she remembers her younger days, the smile the heroes had, when she was born and the warm and wonderful memories. Looking at the shield hero again she is saddened by the scene. A very, very dark hatred, a curse series has been used. She has seen many heroes that used the curse, which gave the heroes power in exchange for being consumed by sadness, so she wants to help him and heal his sadness. Looking at the pink Filolial Queen, she thinks that it is just a normal queen and not a strong one.

Feeling discomfort, "Bird Sanctuary!" Fitoria joins the battle. Mountains of questions appear in her head, why the hero is not stopping the wave, where the other heroes are, why they are only staying in this country, and whether she has to save and defend the world alone to keep her promise with the former heroes.
