Gray Arcadia

Tamaki transfers into an all-boys boarding school built for the children of executives and industry leaders, perched on a mountain and cut off from everything: no phones, no consoles, no television, no trips home even during break. The place exists to keep students studying and nothing else, which is exactly the kind of setup that makes you wonder what's actually going on behind the rules.

He makes three friends early on, and something about how they act doesn't sit right with him. The story follows Tamaki as he tries to work out who among them is being honest and what the school is actually hiding, with the isolation itself turning into part of the threat.

Play consists of reading through Tamaki's time at the school and choosing how he responds to the people around him, with those choices branching toward different endings depending on who he trusts and how far he lets things go. It's a visual novel first, so there's no exploration or management loop to speak of, just the slow unraveling of what's wrong with this place and the people in it.
