exact opposite personality

Kisaki is strong mentally, weak physically
Hina is weak mentally, strong physically
Kisaki is confident and knows what she wants, actively pushing sensei into scenerioes that demand sex. Drugging you, getting a hotel room alone with you and telling you to do whatever you wanted and you'll be forgiven.
Hina is weak willed and doesn't know what she wants, often resulting in cuck jokes due to stronger willed girls running game all over her. Its the reason she became the butt of jokes.
They have a lot of very basic differences.
