Oooohh wah! Ah-h so, Daniel-san. This is a reference to the movie "The Karate Kid", where Mr. Miyagi referred to Daniel as Daniel-san while training him in martial arts.
this is like "The Parent Trap" with a B cup. This is a reference to the 1961 movie "The Parent Trap" starring Hayley Mills and it is about two identical twins who were separated at birth.
