Background / History

Otto serves as the guild master of the Black Rock City Alchemist Guild and is a fourth-tier alchemist. Alongside Frank, he oversees the guild’s first-tier alchemist examination and initially doubts that the untrained Xiao Tianci can pass it. 94 95

Xiao Tianci’s refining technique overturns Otto’s expectations. Otto and Frank are astonished by the refinement process and learn from the young candidate’s methods. 98 99 After Xiao Tianci passes the examination and pursues higher certification, Otto permits Lin Fei, Xue Mei, and other registered alchemists to watch the second-tier assessment. 100 102

Otto and Frank later recruit Xiao Tianci to represent Black Rock City at the Alchemist Conference, offering him a favor in return. 108 109 Otto subsequently assists Xiao Tianci’s search for the ingredients of the Resurrection Pill, checking guild records, identifying Gute as a possible source of the Immortal-Slaying Underworld Flower, and personally guiding Xiao Tianci to Gute’s residence. 111 112 113

At Gute’s trap-filled home, Otto takes the lead through the hazards, breaks down Gute’s reinforced iron door, and helps secure a private setting for Xiao Tianci’s negotiations. 114 115 116 He continues supporting Xiao Tianci afterward, offering the guild’s resources and help acquiring herbs through the Mite'er Auction House. 121 122

Personality

Otto is experienced, practical, and attentive to guild affairs. He initially judges Xiao Tianci by his apparent lack of formal training, but readily revises that judgment after witnessing his talent. 95 98 99

He is supportive of promising younger alchemists, particularly his disciples, while still attempting to preserve fairness during guild assessments. 102 His conduct toward Xiao Tianci becomes increasingly protective and collaborative: he uses his knowledge, connections, and familiarity with dangerous situations to help with the Resurrection Pill ingredients. 112 114 121

Otto also has a combative, long-standing rapport with Gute. He is easily irritated by Gute’s traps and provocations, yet confidently confronts him rather than backing down. 114 115
