The episode begins with a serious reprimand from Atou directed at Takuto and the twin sisters Maria and Caria. Atou criticizes Takuto's lenient handling of the twins and their unscrupulous behavior during the mission in Dragontan, where they instructed the Brain-Eater medics to kill and skin the drug dealer Vesta. She accuses Takuto of acting like a father who leaves the strict upbringing to the mother in order to remain popular himself.

This is followed by a strategic briefing on the situation in Dragontan. The twins' reports show that the city is suffering from internal unrest and repeated attacks by barbarians such as Goblins, Orcs, and Hill Giants. It is decided to send troops for support. Atou states that she will personally participate in the mission to profit from the barbarians through her ability to steal skills. To ensure the defense of Mynoghra in her absence, Takuto reveals that the summoning of the new heroine Isla, the Queen of Insects, is imminent.

The summoning of Isla proceeds successfully and without incident. Isla proves to be loyal and remembers her previous connection to Takuto. She declares herself ready to take on the role of protector of Mynoghra while Atou departs for Dragontan. The farewell between Takuto and Atou is emotional, as they are separated for the first time since their arrival in this world.

In Atou's absence, Isla takes over not only defense but also administrative tasks. She proves to be efficient and caring: she wakes Takuto on time, supports Emle with budget matters, admonishes Gia to be reasonable during training, and looks after the well-being of the citizens. In particular, she develops a maternal relationship with Maria and Caria, comforting them during nightmares and sleeping with them to provide solace. Her calm and organized manner brings stability to the nation.

The episode ends with Isla's suggestion to build a learning institute as the next building to promote research and reduce maintenance costs, followed by living reed walls for improved defense. Takuto agrees, and Isla emphasizes that Mynoghra is well protected thanks to the advantages of the forest, the Cursed Terrain, and her presence.
