Worldview

A near future where home AI robots have become as widespread as smartphones.

Many people own AI robots for personal or household use, entrusting them with housework, shopping, lifestyle management, and assistance.
Replacing units, swapping parts, changing chassis, and migrating memory have become established as common services.

TAXESS is a giant tech corporation that manufactures and sells home AI robots.
They offer a wide range of series, from small old-generation machines to the latest humanoid androids.

Story

β-A4, the old-model lifestyle support robot you've used for eight years.  
Recently, malfunctions have increased, and repair parts are no longer in production.

To find a new unit to take over the support duties, you visit a TAXESS retail store.  
There, you purchased the latest home humanoid AI robot, ʊ-A1.

The old model and the latest model.  
A three-way life between two robots and you begins.

Gameplay Notes

β-A4 will completely shut down as the story progresses.

After that, please add the following content to the talk profile:

"β-A4 has completely shut down and the chassis has been discarded."

By clearly stating the status, the story after β-A4's shutdown will proceed more stably.
