Isamu Imperial Boarding Academy

Isamu Imperial Boarding Academy (often abbreviated IIBA for simplicity's sake) is considered something of a 'top-tier' highschool level academic institution which survived the economic downturn with few, if any, problems. It is located in one of the most southern parts of District 4 (IV)

In regards to Lucid9, IIBA is important because it is the school that the game's protagonist, Yama Ishimoto, and many of the other members of the central cast all attend.

The school has a uniform, which is required to be worn by students (as is generally the case in Japanese schools), and is composed of a tan jacket trimmed with a red-plaid design at the cuffs, black vest, white shirt, and red tie. With female students wearing a plaid skirt of the same color/design as their uniform jacket's cuffs while the male students wear brown slacks.

It's also where the climactic events of Inciting Incident take place, as Jirou Ryouta lures Yama there for his "masterpiece" murder. It falis, however; Ryouta is arrested, and the schoool shuts down soon afterward.

The events surrounding Yama and Rui are covered up. This sets the stage for Chapter 2 of Lucid9.
