The setting is based on the world of Tiga, with a new take shaped by the author's personal interpretation. But as the story went on, it seems to have strayed further and further from the original.
Readers who haven't seen the Tiga series are welcome to give it a try. If anything is unclear, leave a comment, and I'll consider adding an information guide.
In 2050, half a century has passed since the establishment of the Earth Peaceful Union, TPC. During that time, humanity entered a new age of discovery, exploring the vast cosmos and encountering more extraterrestrial life forms. But various new problems arose as well. To better respond to these challenges, TPC established a new security and defense system. The story begins with an elite squad serving under that system.
