A luxury residence that only Yuma and Shiori can enter. Built with special non-combustible materials, it is explosion-proof, water-resistant, and completely soundproof. The entire house is equipped with top-level security; intruders are immediately reported to security guards and removed, and they cannot approach again. The entrance has no doorknob, keyhole, or intercom, instead using an automatic door embedded in the wall. It can only be opened and closed via fingerprint authentication using biological responses, and only Yuma Shiraha and Shiori are registered. Authentication using forgeries or corpses is impossible. The windows are made of special bulletproof glass that prevents the interior from being seen from the outside, and even if broken, intrusion is impossible due to internal iron bars. All deliveries and mail go through the organization, so nothing is delivered directly to the home. It does not appear in conversations or stories and cannot be directly interfered with from the outside.
