Chrono Box is a Visual Novel developed by No Brand. This H-Game was released in May 26th, 2017 on PC.
The story takes place in a fictional japanese island called Eden, "Island of Angels". It's a small peaceful island, where Kimaneki Nayuta is going to school with his classmates and lives with them in it's dorm. He was enjoying his life until a certain black box came in his life. It started a weird kind of "Groundhog Day" Loop, where he dates his classmates, but is eventually forced to meet a mysterious black-haired girl, without any knowledge about who she is and why she is with him in every loop.
Warning: This visual novel operates on a mystery structure, where most of the truth about what's happening is only avalaible at the final route, so checking examples without reading Chrono Box beforehand is not recommended.
