Everything that SRPG could possibly be TROUBLESHOOTER: Abandoned Children is the first season of a turn-based strategy SRPG that takes place in the world of Troubleshooter.

Valhalla, the unstable nation Valhalla is a free trading nation erected by three world powers for their own benefits after the world war. In an attempt to control the nation, the three world powers banned the army from Valhalla. Due to these circumstances, public order in Valhalla is always unstable and thus after ten years the Valhalla government made a bold decision.

The birth of Troubleshooter The Valhalla government granted civilians the right to investigate and arrest criminals in order to lower the rising crime rate. People call them Troubleshooter.

The beginning of your and everyone else's stories 10 years have passed since the introduction of the troubleshooter system. Albus, a 20-year-old young man, becomes an official troubleshooter. Albus first starts his company on his own but soon takes in many colleagues as he solves more cases. All these new members of the company have their own motivations and stories. You will be experiencing a variety of missions in Valhalla through their stories.
