Summary
As the physically largest member of the Spider Family, the Father Spider Demon possesses dark brown skin marked by a red dot-like pattern that extends from his shoulders down to his arms. Like his "Wife" and "Children," he has long, pale white hair that drapes across his shoulders. His most distinctive feature is a face resembling a giant spider, complete with multiple eyes and pincers on both cheeks. He appears to be the most devoted to his family role, repeatedly warning Tanjiro and Inosuke to stay away while trying to kill them. Despite this devotion to the role of "Father" within Rui's fake family, he was notably abusive toward his "Wife," having physically assaulted her in the past without explanation because she was weaker than originally anticipated.
