Usami Suzuno

A cool girl with good looks who is the president of the student council.

She is described as 'The strongest president of all times' because of her skills in accomplishing various reforms within the school.
She respects her father, who comes from a wealthy family and is the president of a foreign company, and always tries to be the daughter who can live up to his expectations.
Suzuno is kind to those she recognizes, but has no interest in those she deem worthless, and is ice-cold to the protagonist.

She has no interest in sexual knowledge, so her only knowledge of sex is everything in a textbook.
