Ichiba Kurogane wa Kasegitai

Ichiba Kurogane, heir to a wealthy business family, wants to earn money through his own efforts. He enrolls at Gakuenzono Academy, where students are judged by how much they earn and all school transactions must use school-yen. Kurogane can spot people with strong earning potential, and he joins forces with Naruko Hana, a young cook whose Japanese cuisine club runs an unpopular restaurant on the verge of closing. Kurogane hopes to help Hana attract customers, but bringing his wallet to school breaks the rules and leaves him with a fine of one billion school-yen. Student council president Asamatsuri Hagane orders him to pay a substantial monthly installment or be expelled. Now Kurogane must try to overcome the fine while pursuing his goal of earning money on his own.
