Circle: Metamorphose

Quick Summary
A unique simulation where you play as a decoy investigation officer fighting perverts on trains, featuring strategic combat, character progression, and fully animated adult scenes with voice acting.
Story Premise
Officer Rina takes on the dangerous role of a decoy investigator, riding crowded train cars to catch perverts in the act. But these aren’t ordinary troublemakers - they’ve got supernatural abilities, high-tech gadgets, and some seriously questionable tactics up their sleeves.
What starts as routine undercover work quickly escalates into intense battles where Rina must use her training and quick thinking to stay one step ahead. The tension builds as each successful arrest makes her stronger, but every mistake could lead to compromising situations that make future encounters even more challenging.
Core Gameplay
This isn’t your typical turn-based combat - it’s a strategic battle system where you need to anticipate enemy moves and choose your responses carefully. The game combines roguelike elements with character progression, making each playthrough feel fresh and challenging.
Combat Mechanics
The battle system lets you see upcoming enemy actions, allowing for strategic planning. You can choose to arrest certain types of attackers while deliberately allowing others to proceed - creating interesting risk-reward scenarios. Level up by successfully making arrests, but be careful not to let your guard down completely.
Character Development
Rina’s body becomes more sensitive as she experiences different situations, which actually affects gameplay difficulty. The progression system is brilliantly designed - what might seem like setbacks actually unlock new strategic options and bonus experience points. You can even save different “development states” to experiment with various approaches.
