And as for the dreams each kid (who seem to have the same name as the guys lol):
Matsumoto Jun: I wanna be a pro baseball player! I wanna be active in lots of games, and have a large house and cool car.
Sakurai Sho: I wish to be a musician in the future. It’s because I’ve been learning the electone since young and I love music.
Aiba Masaki: My future dream is to become a company president. I wanna be a cool president who wears a beard.
Ninomiya Kazunari: My dream is to become a pro baseball player. I will definitely throw the opening pitch in the Tokyo Dome.
Ohno Satoshi: I want to become a baker in the future. It’s because I love the smell (of bread)!
