Description
Barack is a supporting character introduced in the three-episode original net animation arc, Visions of Coleus. He is a resident of the Kingdom of Coleus and is married to a woman named Chiffon. The couple holds a position of sufficient influence within the kingdom to request a private meeting with Rimuru Tempest upon the slime's arrival, specifically excluding Rimuru's attendant, Paulo, from the discussion. During this meeting, Barack and Chiffon inform Rimuru about the ongoing violent clashes between the two royal brothers, Aslan and Souther, as well as the mysterious illness afflicting their sister, Princess Zenobia.

Barack is portrayed as an active participant in the kingdom's political and military struggles. Concerned about the escalating succession crisis, he aligns himself with Prince Aslan's faction and joins their forces to confront the opposing side led by Prince Souther. His personality appears to be pragmatic and somewhat guarded, as shown by his initial decision to keep a visiting outsider like Rimuru separated from his attendant for a confidential conversation. He is also perceptive and observant; he correctly deduces that Souei, one of Rimuru's shadow subordinates, had been covertly monitoring the kingdom's activities for a significant period.

Barack's primary role in the story is that of a supporting figure within the Coleus power structure who becomes a collaborator with Rimuru to resolve the kingdom's turmoil. He is deeply involved in the central conflict, which is later revealed to be orchestrated by the royal physician Gustav and his associate Carl, both of whom are arch demons in disguise. After Rimuru exposes the demons' plot and Princess Zenobia is saved, Barack helps facilitate a crucial meeting that brings together the three royal siblings—Aslan, Souther, and Zenobia—with Rimuru to discuss the full scope of the conspiracy and formally conclude the arc. His key relationships are with his wife, Chiffon, with whom he acts as a unified front, and with Prince Aslan, whom he actively supports in the succession struggle. He also demonstrates a degree of physical capability, as he is part of the force intercepted by the powerful warriors Benimaru and Souei, suggesting he is not merely a political figure but someone willing to take part in direct action. Following the resolution of the crisis, Barack's standing in the kingdom remains secure, and he is later seen attending a festival in the nation of Tempest as an audience member.
