Players take control of a rookie police officer who has just graduated from the police academy and must complete a 30-day evaluation period.

Her primary duty is to patrol Central Park in Kurakucho. In addition to routine patrols and public safety promotions, she must also respond to various random criminal incidents. Some criminals are extremely brutal — if she fails in combat, the protagonist may face humiliating consequences.

If you feel your abilities are lacking, you can visit training facilities throughout the city to undergo special training and improve your stats. If the security level of Central Park remains too low, there is a risk of being dismissed early.

The game features rich side stories and collectible elements, so a certain amount of patience is required during gameplay.
