Description
Oyadarma, also romanized as Oyadama, is a supporting antagonist in the anime Time Bokan 24 and its sequel Time Bokan: The Villains Strike Back, where he serves as the hidden mastermind behind the series' villainous organization. He is the owner and president of History Paradise, the world's largest textbook publishing company in the 24th century, and the direct superior of the Akudama Trio, the three-person villain group that carries out field missions. In his public role he appears to be a respectable corporate leader, but on screen his face is always concealed behind a skull-shaped mosaic, underscoring his position as a mysterious figure who operates from behind the scenes.

His central motivation in the first series is to preserve the officially taught version of history, which is revealed to be a fabricated textbook history that hides the true events of the past. Because History Paradise supplies the standard history textbooks used throughout the 24th century, any discovery of true history would force enormous rewrites of the company's publications, and Oyadarma sends the Akudama Trio into the past to obstruct the Time-Space Administration Bureau's investigations in each era. In the sequel, his objectives shift: he orders the trio to travel through history and collect Dynamonds, valuable treasures associated with famous historical figures, giving the second season its central mission.

In the story, Oyadarma functions as the employer and taskmaster of the Akudama Trio. He assigns missions, monitors their results, and disciplines them after their defeats, with the recurring punishment routines serving as one of the series' running gags. At the end of the first season's conflict, he issues the trio a six-month suspension of operations, and in the sequel he reactivates them with the Dynamond-collecting assignment. In the second series he also appears in a recurring educational segment presented as a weekly surprising trivia corner, delivered in character as part of the show's comedic and mock-educational tone.

His key relationships are defined by his authority. He is the boss of the Akudama Trio, whose three members, the leader Bimajo, the mechanic Tsubuyakky, and the strongman Suzukky, answer directly to him and must endure his orders and punishments despite their low pay and heavy workload. On the opposing side, his efforts to keep history hidden place him in conflict with the young time agents Tokio and Calen, whose mission to expose true history directly threatens his company's control over historical knowledge.

His personal background is not explored in the series, and his face remains hidden throughout both seasons. Rather than engaging in direct combat, Oyadarma wields institutional power: his company shapes what people believe about history, and his authority allows him to direct the trio's missions, suspend their operations, and impose punishments at will. This combination of concealed identity, corporate status, and control over information makes him the ultimate figure behind the series' conflicts.
