Full Summary
Pluton Ainzach invites Momon into his office for a personal request. Theo Rakheshir is also present in the room and welcomes the adamantite adventurer. Surprised by the presence of two guildmaster's, Momon feels honored, and continues to be courteous despite the attempts of the older men to relax. Ainzach's has a request to retrieve a rare herb grown in the northern region of the Great Forest of Tob. Momon happily accepts the request, though Ainzach warns him that the task might be too difficult. Thirty years ago, a team of adamantite, along with two teams of mythril adventurers, undertook the quest before, underlying the seriousness of the situation.

Despite their protests Momon, agrees to the request and decides to prepare to embark on the mission. After the adventurer left, both Ainzach and Rakheshir have a discussion on Momon's seemingly selfless personality. On the topic of Momon's origins Rakheshir believes him to be a former noble, as evidence by his high quality gear and magical items in his possession. He also has reason to believe that Nabe to be some sort of relative of his or servant, explaining her loyalty. While Momon has stated what brought him to the Re-Estize Kingdom was a vampire, who they believed may have destroyed his kingdom, Azinach laments at the day where Momon may leave.
