1 : The Golden Tech Samurai

After Professor Suzuha Tanako invented Tech Swords in 2065, the world collapsed in chaos. Tech Swords were originally available to everyone in Japan. The so-called "Tech Swords" were used like katanas, but as soon as you pull a Tech Sword you are automatically surrounded by a samurai-like armor, the strength of this armor depends on the strength of your Tech Sword. In addition, each high-level tech sword also has a unique ability. But little by little clans formed which made every single section in Japan unsafe. This was followed by the first tech war. All clans fought each other, but one Samurai stood out, the Golden Tech Samurai, the people gave him this name because the blade of his Tech Sword and his armor were gold, he was feared everywhere because he was considered invincible. As this gradually got out of hand, the government decided that Tech Swords should only be available for specially trained units. Since then, there has been no trace of the Golden Tech Samurai.
