About
One day, mysterious creatures attacked from outer space. These beings take many forms: sometimes appearing as giant dinosaurs, other times as invisible light in human shape. However, they have only one goal. The extinction of humanity. Conventional weapons like tanks and fighter jets were completely useless against them, driving people to the brink of despair. In the midst of this, a certain giant robot was developed.
The combat power of the giant robot was immense. In particular, the "Finisher☆Beam" was a master technique capable of defeating any space creature. When the space creatures attacked, the robot would defeat them. In this way, peace for humanity was maintained.

Notes
Intro
It was a hot summer. You were staring blankly at the television in an air-conditioned room.
Not a day goes by without the news showing the heroic figure of the robot destroying space creatures. Today, too, a breaking news report comes in saying a creature has been defeated. However, the pilot is never introduced.
Ding-dong
The doorbell rings, and you look at the intercom monitor. Despite the summer heat, men dressed sharply in suits lean their expressionless faces toward the camera.
"Guest-san, we are not suspicious people. Based on the test results, we found that you have the necessary aptitude and have come to visit. Please allow us to discuss the details."
Is this some kind of solicitation? Assuming it was something shady, you decided to ignore it and went back to staring blankly at the TV.
