This Is Frustrating Jin-woo visits his comatose mother and decides to push forward with getting stronger so that he can get the needed ingredients to save her; he thus accepts Jin-ho's request to aid in running dungeons to allow creation of a guild. To fulfill the party member requirement for C-rank dungeons, the Hunters Association recruits the survivors of the double dungeon raid (Jin-woo, Joo-hee, Chi-yul, Kim Sangshik, and Kang Jeongho), and due to a shortage of Hunters in the area, the group is rounded out by several imprisoned Hunters, who serve in exchange for reduced sentences, that are overseen by B-rank Kang Taeshik.
