Tsuneo Haraguchi

Tsuneo's mother, orders Tetsuko to pay for what she did to her son but Tetsuko blackmails her instead, saying that she is ready to inform a news company of what has happened to Tsuneo and receives one million yen hush money. Expelled from school, she comes to Tokyo, intending to take a round-the-world trip. But Sankichi (Yoshihiko Aoyama), a jack-of-all-trades, cheats her. So, she makes up her mind to catch him and get back her money.
Shiro Usami
When Daisaku Hotta (Kosaburo Onogawa), the cheer leader of Tonan High School, hears that Rikiya Kudo (Saburo Shindo), the captain of the Judo team and Shiro Usami (Kei Wakakura) of the boxing team are about to fight, he breaks it up that are apt to erupt so suddenly on campus. Rikiya is an honor student, recommended to the Toa University by his school and is almost certain of being accepted next spring. Shiro is long on brute strength but short on brains. Naturally, they waste little love on each other, so there is very little ground for any understanding between them.
