An old woman was close with Warrior Gorilla when he was in the town near the Rohr Road. The stubborn old woman makes Frieren's Party complete several tasks, such as polishing a statue of forgotten heroes, before she tells Sein what direction Gorilla headed off towards. She tells Sein that while Gorilla was not able to polish the forgotten statues as well as they did, his name was memorable. (Source: Frieren: Beyond Journey's End Wiki)
