In Episode 10, Freya explains a War Game against the other Familias, with the condition that Bell Cranel will belong to her if she wins, and she returns to heaven if she loses. Freya challenges the opposition to ally with other Familias, while she only fights with her own Familia. The Guild intervenes and prohibits the Loki Familia from participating to prevent a power imbalance, causing frustration among those who wish to oppose Freya.

Despite the restrictions, various Familias and individuals gather to support Bell and the Hestia Familia. Finn provides Liliruca with strategic guidance for the upcoming battle. Welf promises to forge as many magic swords as possible, while other allies provide training and resources. The War Game is set as a game of hide-and-seek in the ruins of Olza City, where the gods hide and their children seek them. Battles between the children are allowed, but no harm may come to the gods.

During the preparations, Bell reaches Level 5 and gains new abilities, boosting his confidence. However, concerns remain about facing Freya's powerful children. Within the Freya Familia, internal conflicts arise; some members question Freya's motives or show fear and hesitation. On the day of the War Game, the allied army gathers, strengthened by the support of various Familias and individuals, with determination.

The episode ends with the start of the War Game, setting the stage for a major confrontation that could determine Bell's fate and shift the power dynamics in Orario.
