The episode begins with a marriage counselor talking to Bolg about his prospects of finding a partner. The counselor mentions that Bolg, a level 12 knight at the age of 42, might have difficulty finding a suitable partner since his level is too low for his age, and stamina declines with age, which is typical for knights. Two onlookers, Saitou and Lafanpan, eavesdrop on the conversation and comment on the unexpected existence of marriage counseling in this world and the difficulties of finding a partner, as the use of weapons and magic increases while adventurers' incomes decline. Morlock arrives to find a woman and approaches Saitou, but the counselor reminds him of the registration fee.

Later, Saitou and Raelza encounter Morlock in the labyrinth, who is trying to court a succubus, and stumble upon a trap that he, as Lafanpan assures, can disarm. The kingdom's official hero celebration is discussed and broadcast live, and Monpui is included in the group due to his intelligence.

Saitou reflects on his journey to this world and expresses his gratitude for finding a place where he can be useful. At one point, Raelza referred to Saitou as an "old geezer," but Lafanpan intervened before the conversation could escalate. Morlock then explained that he sensed no magical power in Saitou, leading him to suspect that Saitou might not even be from their world.

The group also talked about the iron golem they had encountered earlier, trying to determine whether it was magic or clockwork. Saitou suggested going to the tenth floor to search for debris. They also discussed the entrance fee for the great labyrinth, which was managed by the government and which they couldn't afford.

When they reached their destination, Saitou discovered a vacuum cleaner robot and ordered it to return to where it belonged. The result was that the great labyrinth expanded, and the new area was named "Saitou's Tunnel." Adventurers from across the kingdom flocked to it.
