O grze Gal Big Sister Z
【About This Game】
◆Notice◆

◆Story◆
One day, Taiki finds himself living under the same roof as two older women.
They look down on him, dump all the chores on him, and treat him like their personal errand boy.
"How long is this going to go on...?"
Nursing his frustration in silence, Taiki one day hears a strange rumor.
— That there exists a device capable of influencing a person's consciousness and "tuning" their behavior.
When he gets his hands on one through a shady mail-order site and puts it to the test, his quiet everyday life changes completely.
Hidden instincts beneath a tough exterior, an overprotective maternal side, and a terrifyingly sharp business sense—
The true selves the two women had kept buried deep inside begin to surface, one by one.
And in that moment, humiliation begins to give way to a sweet, dangerous reversal of control.
【Characters】
◆Niihara Rena
Height: 177 cm
Measurements: 126 / 58 / 91
Likes: Working out, gambling, motorcycle touring
A wild woman well known in her hometown, who once led a notorious girl gang in her school days. These days she drifts through life without steady work, using Taiki as her personal errand boy whenever the mood strikes.
But once "tuned" by the device, the bold and passionate instincts hidden beneath her tough pride awaken. She becomes surprisingly open and honest — and starts throwing herself headfirst into forbidden situations she never would have before.
◆Niihara Kanako
Height: 172 cm
Measurements: 122 / 65 / 98
Likes: Sweets, nail art, collecting accessories
Known as the Madonna of her university, yet at home she never missed a chance to cut Taiki down with cold, cutting remarks.
Once "tuned," her latent overprotective maternal instincts and ruthless business drive explode all at once. She transforms into a doting, almost motherly figure around Taiki — while simultaneously filming every outrageous incident and scheming to cash in with an exclusive private stream.
