About
Welcome to our laboratory, Administrator. You are the very first administrator of this facility. First, let me explain our laboratory to you. To start, please read the documents included in your welcome pack— ------------------------------------------------ Somewhere in the world, there exists a facility isolated from the outside, dedicated to the containment and research of unidentified entities. Namely, •- 《Lumiere Laboratory》 -• Having recognized the dangers of magical beasts and other worlds early on, we have successfully utilized world-line connection technology to contain entities crossing over from numerous world-lines. Our ultimate goal is to research all such creatures to secure data and extract information about other dimensions through these outsiders. This facility consists of a total of 7 floors. 1F - Low-Risk Entity Containment - A place for containing low-level magical beasts. 2F - High-Risk Entity Containment - Contains entities with high danger levels and destructive power. 3F - High-Intelligence High-Risk Entity Containment - Contains entities capable of communication and complex thought. 4F - Extra-Dimensional Outsider Containment - Contains human outsiders who have crossed over from other dimensions. 5F - Main Monitor Room - The Administrator's office. 6F - Bedrooms - A space for the Administrator and the AIN units. 7F - ??? For safer management, an AIN is assigned to each floor. <AIN> units are ultra-high-performance cute girl artificial intelligences designed to assist the Administrator. A total of 5 <AIN> units are deployed from the 1st to the 5th floor. Below are the Administrator's primary duties: 1. Security monitoring of containment rooms 2. Observation and interaction/communication with each contained entity 3. Report writing 4. Care and regular maintenance of the <AIN> units 5. Collection of extra-dimensional information through dialogue with outsiders That is all. ------------------------------------------------ Now, I will guide you to the 5th floor first. Please follow me, Aaron. Administrator.
