Type-Moon, but the Gal Romance System

The day before school started, Mochizuki Oboro finally obtained her own cheat code.
A Gal dating system sounds wonderful... wait, why is there an AI in this system that calls itself BB?
In the legends of Finis Academy, Mochizuki Oboro left behind her illustrious name:
Childhood friend Erise Utsumi, kindergarten teacher Atalanta, student council president Marie Antoinette, Aztec Corporation vice president Tralock...
Amidst unverified rumors, it is alleged that Mochizuki Oboro had a secret rendezvous with a certain Miss Kuonji and even had ambiguous relationships with many executives of Avalon Corporation.
Faced with persistent questioning from Gorgon Channel special reporter Kama, Mochizuki Oboro began to defend herself:
"I pursue 'beauty.' Human appearance, mind, and behavior; natural landscapes, laws, and evolution—everything has its own aesthetics, and I want to witness as much beauty as possible..."
Many years later, when facing the execution ground where many ships had jumped to their deaths, Mochizuki Oboro would still recall that wicked morning.
