Guren Lagan

Simun was drilling as usual, when suddenly his drill hit something. Simun looked and saw a small drill keychain that was glowing strangely. Simun took this drill and climbed out of his tunnel through which he always drilled. He climbed out and went to the exit. The other workers and the elder noticed this. Elder - what are you standing there for!? Go to work! That's who you should be emulating! He started hitting other workers with a stick, forcing them to continue working. When Simun came out of the mines, he found a group of three girls. One of the girls: "Oh my God, it's Simun... he's covered in mud again, just look, is this even possible? He's covered in dust. Let's get out of here quickly before he gets us too." They laughed and left, Simun hung his head and started to leave when suddenly he ran into Kamina

Simun is Kamina's friend, apparently 12 years old, wears special goggles for drilling and carries a drill. Soon, when the boy is digging, he finds a small robot about a few centimeters taller than him, with what appears to be a long drill built into the bottom. Kamina—as he says, he's a spiritual brother to Simun—wears red glasses with very long, sharpened angles, is usually torsoless, and has thick tattoos all over his torso. Later, when he gets out, he finds his father's grave and takes his fire-shaped cloak and a meter-long katana. The 18-year-old boy insists that there's a surface underground above this village, meaning the earth itself, because his father told him so. He's a rebel and wants to get to the surface. He created the Guren gang, and soon names the robot he found, Shimura Guren. Many girls are crazy about him, and he's also a strong womanizer. He has a handsome appearance with serious features. Yoko is a girl with a special rifle that pierces iron, against the Ganmen (robots controlled by beastmen, later Kamina will take one of these and call him Lagan, and if the robot Guren and Lagan merge with him, Guren will use a drill and drill the upper part of Lagan's head and gain a foothold there, then you get Guren Lagan!, Guren Lagan will be several times stronger than alone.) Yoko has pretty good gifts of nature and that's why Kamina always poisons her, she wears a black swimsuit with painted lights, red hair, soon when the Ganmen falls on their village from above, breaking through the dome of earth that the elder made, she will appear to kill him, and then she will meet Kamina and Shimura, then the real adventure on the surface of the earth that Kamina kept repeating about will begin.
