Tadanori Sera (世良 忠典 Sera Tadanori) is a minor character in the Free! series beginning with Free!-Eternal Summer-. He is a third-year student at Iwatobi High School and the captain of the Iwatobi Track Club.


Tadanori is a tall young man with a toned, slender build. As a third year, he wears the same school uniform as Haruka Nanase and Makoto Tachibana -- a white shirt with a green, dotted tie and gray pants. His droopy eyes are olive green and his hair is a dark green. He wear half-frame corrective lenses.


He seems to be an observant and understanding individual with good leadership qualities, evidenced by the fact that he is Captain of the Track team. When Rei Ryugazaki decides to join the Iwatobi High School Swim Club, he visits Tadanori, but grows anxious about what he's about to say. He stalls by talking about other things until, finally, Tadanori asks him if he wants to quit track. Rei is surprised at this, but Tadanori explains that he'd noticed the swim club members hanging around watching Rei.


Tadanori first appears in episode 15 - asking if Rei would be interested in rejoining the track team after Rei's lacklustre performance at a tournament.
