The Birth of Smallest Hero
Nagasawa is in the same gym class as Shuto Katsuragi.
Nagasawa is an average teen with black hair, and wears a standard school uniform.
He is a very popular student and good at sports, however he regularly makes fun of Shuto for his height and his dream of becoming a hero. Also despite passing the Hero Jr. Test, it does not stop him from mercelessly beating up Shuto with a total lack of concern for the difference in strength. His personality also includes cruelty and cowardice, as he also beats up on him with the help of some cohorts, only due to the fact that Shuto wasn't going to take his insults anymore.
Along with being good at sports, he tends to hog all of the attention to where Kanta even commented on the fact that he hated being on his team because he never got to do anything. Shuto even suggests that he is doing this purely to get the girls' attention, which from his reaction heavily suggests so.
Nothing of Nagasawa's past is known.
