Since humans entered the age of the universe, the original two genders have evolved into six. Which six specifically? Please do it yourself.
As a qualified A, Captain Redmond has been working in the sword commando team of the Federal Third Army after graduating from the military academy, code-named "Knights". Unlike the First and Second Legions, Captain Redmond's Third Legion has always been the Blade of the Federation fighting at the forefront! And his sword commando team is the sharpest among them!
Today, when the life expectancy of federal people generally reaches 300 years, Captain Redmond, who is just 40 years old, is still very young, but he is the top-notch presence in the Third Army in terms of qualifications and strength.
During a campaign to suppress space pirates, the outstanding A was accidentally taken to a planet that had never been marked by a malfunctioning mecha. Then on the first night on this strange planet, he asked O about the smell of estrus.
