A rouge-lite simulation animated game where you play as Rina, a special investigator with psychic powers that aims to cut down crime rate on trains. Upgrade your skills, combine them, and take down your enemies before they get you! Oh, and have fun changing Rina's outfits too!

Due to increasing criminal activity on trains, the police begin a special plan called the Undercover Train Operation. A new unit of Train Investigators with psychic powers is formed for the operation. One of their lead investigators by the name of Rina gets captured by the offenders -- lead by Kaito -- and she loses her powers.
However, it won't stop her from doing her duty. Will she be able to catch Kaito and his accomplices and return her powers, or will she lose and quit the job?

Play this rouge-lite game as Special Train Investigator Rina and catch the criminal offenders in trains using psychic powers. You need to precisely manage the timing of your and your enemies' skills. Predict the future and avoid attacks using the Foresight skill, stun enemies using the Electric Shock skill, and freeze them using the Blizzard skill. Find the offenders using the Awareness skill and arrest them! Earn experience, level up, and choose the upgrade you want to acquire. On every train station you will see a random event which may help you during your mission, or interfere with it. There will be a unique boss fight at the end of the mission. Build different tactics, buy yourself upgrades, catch the offenders, and enjoy the game!

Choose your skills with every level up. If you lose, unlock upgrades with skill points acquired during missions.
Each mission will have a different boss that you need to defeat and capture. Each of them has unique abilities and will require different tactics to win.
Choose what action to take on your turn wisely, and watch out for enemies' actions as well. Use your active skills even on the enemies' turn! Keep an eye on the timer to use your active skills in the best moment!
Buy different outfits for Rina to go on missions, each with different bonus abilities!
