Oda Nobukatsu is the historical older brother of Oda Nobunaga from the Sengoku period. In the Fate series, particularly Fate/Grand Order, he does not appear as a summonable Servant or major character based on available information. He is referenced indirectly in contexts related to Oda Nobunaga, such as family relations, but lacks a dedicated profile, appearance, or detailed lore in the series.
