Synopsis
My name is Wargakid. It is a famous crime robot in the 24th century. Well, I can say it myself. Anyway, I came in the 21st century with a little trouble. In this era of undeveloped science and technology, you can do whatever you want. However, there is a problem here as well. Due to the influence of time slip, my power level was set to the lowest value, and it became completely useless. As a bonus, it is used by cheeky junior high school students. But it will definitely come back soon. Look at it !!
