After imprisoning Tatsumi, Budo informs Honest of his son's death at the hands of Lubbock, but was disgusted of the Prime Minister's lack of sympathy for his own kin.

At Tatsumi's execution, Budo was present where he noticed Honest's quick leave after the child Emperor's speech before a large crowd gathered to witness a Night Raid member's execution. When Night Raid arrived to rescue Tatsumi, Budo was quick to battle them.
