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 Philorial. Fitoria who is entrusted by former heroes to defend the world in their place. Fitoria remembers, that new Heroes are summoned but wondered why they haven't done anything about the coming waves. As she thinks, Philorials minions returned, 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 Philorial minions have short memory). She asks what happened and they answer, that they found a monster Philorial, that is not like any, it is drool at Philorials, bigger size, white, red, pink color and many heads. Understanding that only Philorial raised by heroes are able to become Philorial Queen/King, Fitoria wants to meet this new Philorial Queen.

As the search for the new Philorial Queen starts, they went to a Philorial ranch to look for information. In the ranch, a Black Philorial, named Mr.Black, saw the cute Fitoria and asks her to be his harem. Fitoria gets mad, kicks him and then heals him (she over did it). As Mr.Black runs away, an old Philorial comes and apologizes for Mr.black. Fitoria asks about the new Philorial Queen, he told her that its a normal Philorial Queen but unknown where she is. The Philorial minions find out that she headed southwest.

Continue traveling southwest, she heard a dragon shout. She finds a monster with dragon fragment attacking a human city, defending the city is a Pink Philorial Queen and a person with shield on his back. As she saw the scene, she remembers her younger days, when she was born and the smile the hero had, 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 is been used. She has seen many heroes that used the curse, which gave the heroes power, but at the cost of being consumed by sadness, so she wants to help and heal his sadness. Looking at the Pink Philorial 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 question appear in her head, Why is the hero not stopping the wave, where are the other heroes, why are they only staying in this country, and whether she has to save and defend the world alone to keep her promise with the former heroes.
