Canon
As seen from the family's past, Touya didn't initially have a good impression of his younger brother upon his birth, due to him having realized what their father was trying to do by having more children. Despite this, Touya and Natsuo grew extremely close to each other, to the point of being inseparable, as they always played together as kids. Touya would also tell Natsuo everything about his inner thoughts and turmoil and lean on him for emotional comfort. It's implied that he felt a sense of camaraderie with Natsuo as he considered that they were both their father's "failed creations". To Touya, Natsuo was the only one who could understand him and the only one he could talk to, and when Natsuo suggested that he talked to Fuyumi about his problems instead of him once in a while, Touya was deeply hurt by the implication that Natsuo was brushing him off, to the point of nearly crying. His supposed death, which happened shortly after his mother went away, greatly affected Natsuo, which caused him to greatly resent his father, whom he considers to be primarily responsible for what happened to Touya. Nowadays, Natsuo still remembers Touya and still can't forgive his father for it. When Touya revealed himself in public in an attempt to attack Endeavor and Hawks, Natsuo appeared greatly shocked by this despite not knowing his true identity around that time. Around the time of the Paranormal Liberation War, Touya mentions Natsuo when he delivers his speech to Endeavor, implying he still fondly remembers him despite them not seeing each other in a long time. When Touya revealed his identity as Touya, Natsuo was shown to be horrified when he saw what his older brother had become on his phone. Alas, when Shoto criticizes him for sending a villain that nearly killed the same brother he loved and depended on, Touya replies that it was a shame he didn't die because Endeavor would have suffered more, only caring about inflicting as much suffering onto Endeavor as possible even if it means sacrificing his family.
