The Hestia Familia is given their first mandatory assignment from the Guild, which involves exploring the lower levels, a first time for Bell and the others. Hestia decides to form an expedition team, inviting members from the Miach and Takemikazuchi Familias to help with the task. Aisha volunteers to join the expedition as well and helps with Haruhime's magic training, while Lilliluka, who is one of the weakest members, accepts Daphne's suggestion to act as a strategist for the team, leaving the fighting to the others, while Welf also creates new equipment for the whole party.

Unable to extract the Vines from Luvis and Chigusa, the party discovers that the monster is an irregular type of monster called a "Moss Huge" who evolved after eating the magic stones from other monsters and is attacking adventurers to steal those in their possession. Luvis had taken his magic stones to act as a diversion for his companions to escape, unaware that the monster captured them. Concluding that they must defeat the monster to save their companions, Bell and the others look for the Moss Huge, but fall in the trap when the monster uses the corpse of one of Luvis' friends as a decoy.

Overpowered by the Moss Huge, the other adventurers decide to sacrifice themselves to allow Lili and the others to escape, but she refuses. Bell rejoins them and fights the Moss Huge alone. Having finally adjusted to his newfound strength in the lower floors, Bell combines Hestia's Knife with his Firebolt and Argonaut spells, creating his new special move "Argo Vesta" that he uses to destroy the Moss Huge with ease, dispelling the vines from the injured.

Meanwhile, Jura, who is a monster tamer, also sets a Lambton against Bell and Ryū and reveals all his planning to taunt them.
