Masahiro Setgawa has the lead role in Hijome my hero.


When he was younger, Masahiro had orange hair and usually wore a white button shirt with a small chain necklace.

Currently, he is seen mostly in his high school uniform. He has blonde hair longer on top in proportion to the sides and small, green eyes. He maintains a chain necklace on his neck and has piercings on his ears.

Later in the book, he wears a chain with a ring attached to it as a necklace.


Previously described as a 'helpless delinquent', Masahiro is a reserved and realistic person who often degrades himself and apologizes for anything he may have done to upset others, but there are also times where he stands up for himself. One example is if someone insults the one he loves.

He has a strained relationship with Megumi Setagawa (Masahiro's mother) as he disagrees with her sexual profession, which caused him to have to learn how to be independent. At an early age, he was able to cook and clean very well.

As the series goes continues, he is able to act more confident, and he even displays his dominant side.


Not much is known for sure about Masahiro's history, but it is implied that his father either left the family or he died for unknown causes when Masahiro was young. He disliked Hero themed shows as a kid, finding them unrealistic. His mother seems to be some sort of host or possibly a prostitute. It is made apparent that this makes Masahiro uncomfortable, so much that Masahiro does not go to his own home if she has 'clients'.
