22-year-old Ko Ichinomiya - Todaya student and heir of a huge concern. But, boy, family following the motto "Do not be no one should" prefer not to use the family money and connections, and long lived and earned their own, becoming a successful businessman and financier. That`s just in practice a young Ko rotates in the virtual world,being "far from the people," and therefore, when after falling from a bridge into a river Arakawa saves him pretty homeless girl Nino, a long time could not figure out how to repay the savior - in fact no money, no stone chambers, anything she does not need it! The problem is that the motto of the Clan Ichinomiya is so firmly entrenched in the flesh and blood of the heir,that was imposed on family asthma, and if Co is not received, as it should, it may be corny suffocate. Taking pity on the guy, Nino said simply: "Do you want to pay back? Then love me and live with me. " Thus began the life of a young financial genius to Arakawa under the bridge together with the beloved, in the community of local hippies and freaks.And it turned out not so bad - raw fish Japanese surprise, ancestors lived and worse, and all sorts of monsters and aliens - normal guys, if you help us by becoming a little better and more humane.
