Utau: Tumbling Dice: Watashitachi 3nin, A Ge Ru

In order to pay off the 1.1 billion yen debt that you accrued as you attempted to help a dying elderly man, you've decided to manage a karaoke facility that also doubles as your place of residence. You manage the facility with the three lovely granddaughters of the old man (who also live there) and attempt to increase your earnings by attracting new customers. You'll have to make advertisements and commercials and set a work schedule that doesn't push the girls too hard.
