If the player kidnaps the daughter of the family, they can record her, but only at night. A video will be sent to the father of Musume begging for help. They will negotiate the fate of Musume using text messages. Musume's father will free Kokona's family and other clients from debt after this.
It may be possible that instead of kidnapping Musume, the player could fight Mr. Ronshaku in order to free his clients. Yandere-chan would fight in a Yakuza-style mini game that would end in her ramming his head into a door until he gives in. However, in a later video uploaded on June 6th, 2016 called "The Verdict On Yesterday's Proposal", YandereDev decided that he will not implement this feature after all, as it would not fit with the "social stealth" tone of the game.
This family was implemented in the June 1st, 2016 Build.
Ronshaku is a play on the words "Loan Shark" when transcribed into Japanese Katakana: rōnshāku (ローンシャーク)
