Loto 9 - Kin ni Kusshita Onna-tachi

"Take me... Kyuu-chan" Kyuusaku Toda, a 46-year-old dull janitor, suddenly won 30 billion yen from a Loto 9 ticket he bought. With the power of this huge wealth, this middle-aged bachelor's life of being ignored by women as if it were by destiny, gets a complete turnaround!? Halfway until then, all the women who seemed like they've been making a mockery out of him, began to yield one by one with the use of his 30 billion... an intelligent and beautiful teacher, the academy's most fashionable gal, and even a kind-hearted girl troubled by her parents' debt... The moment they learned of Kyuusaku's financial power, the discerning eyes of the women who were once thought of as prizes beyond reach had changed; before long with that power, even the unsophisticated Kyuusaku's inner self began to turn pitch black... How far will the lure of a stack of money drive a person crazy?! (Source: DLsite)
