Hideyoshi serves as a retainer under Oda Nobunaga, advancing from an errand boy to a trusted general. His peasant origins and rise to military responsibility remain consistent. He exhibits extreme physical resilience, surviving incidents like multiple arrow wounds without lasting harm. His personality blends clumsiness and density, sparking comedic mishaps where he becomes a target of physical accidents or disparaging remarks. He bears the nickname "Saru" (monkey), reflecting historical descriptions of his appearance.

Early in his service, he remains oblivious to romantic overtures from Nene, who displays tsundere tendencies—masking genuine affection with hostility or dismissal. Their relationship evolves into marriage, shifting from misunderstanding to mutual devotion, though Nene’s comically poor cooking occasionally disrupts their domestic life.

Hideyoshi proves fiercely loyal to Nobunaga in pivotal battles like the Siege of Inabayama and the Battle of Anegawa. His frequent misinterpretations of situations lead to humorous blunders, such as provoking Nobunaga’s fury by misspeaking about Oichi’s physical measurements. Despite his comedic role, he actively participates in Nobunaga’s strategic command structure.

His marriage to Nene stabilizes into affectionate partnership after initial tensions ease, with both supporting each other despite culinary mishaps. Hideyoshi’s narrative arc centers exclusively on his service under Nobunaga, omitting later historical events like his own ascension to power. The portrayal consistently highlights his accident-prone yet unyielding nature within the comedic context of Nobunaga’s campaigns.
