Black Rock Exorcist-
In the strange world, the blue girl feeled far away a presence, wich was not from this world. She soon went to investigate it, getting hold of both her cannon and katana.
The boy with the blue flames, Okumura Rin, was sleeping, but when he woke up, he looked around and said:
Rin: WHERE THE FU** AM I?!
He deduced that he was not in the True Cross Academy soon, although is very large and has dimensional portals, none of them goes to a place where the sky has a green color.
He wandered for a while, trying to discover where he was and find people to help him. However, someone was watching over him. As soon as he wanted to rest under a rock, the floor crushed and revealed a girl. A red-skinned girl with long red hair, two large horns over her head, claw like hands, red eyes, wearing shorts and a bikini like-top, holding a large sword. The girl didn't hesitated to attack Rin.
Rin immediately wielded his sword, the Kurikara, a sword that seals Rin abilities. When he wields it, the seal is broken, and just like now, it lets Rin fires his blue flames. This flames serves as the proof that Rin is the son of the god of Demons, Satan.
The girl and he clashed their swords immediately, with enough strength to push them back away very far.
Rin clashed into a castle, he thinked for a minute that he was safe there, but suddenly another girl jumped in front of him. A green-skinned girl wirh a bit curly green hair, claw like-hands, two horns and a green veil over her head, green thin wings on her back, green eyes, wearing a gothic lolita-like dress, glasses and holding a large scythe.
Immeditely, the girl sent two large black skull whom he managed to split in half, but the girl made a surprise attack and just as before, he was pushed back far way.
This time he clashed on a desert where he saw another girl. A gray-skinned girl, with short white hair, light orange eyes, a robotic skeletal-like tail, wearing somewhat like a black dress, a hood, white stockings and instead of normal arms, she had robotic large scale arms. When she saw Rin, she used her arms to make the earth tremble, wich opened a hole on the ground were Rin fell.
Now, he clashed on a giant playground like place. Thinking the place was dangerous like the others, he tried to get off from there, just only to be attacked by a giant scorpion like robot. He managed to destroy it soon with the power of his flames however but before doing that, the robot pilot jumped to reveal it was another girl. A yellow-skinned girl, who also had claw like hands, with blonde hair, a crown on her head, yellow eyes, wearing a black dress with yellow stripes, holding a sword and a large shield, and had two wheels instead of feet.
The girl and Rin fought in a sword match. The girl had much advantage, but Rin managed to get on. The place suddenly crumbled, due to the match, crumbling the girl on it.
Rin thinked he was finally safe, but then, he heard four voices saying "Die" repeatdly at the same time. The girl digged her way to the surface and the other three girls Rin fought jumped in front of him, with all of them saying "Die" to Rin, but Rin scared even more when he saw these girls displaying flames from their eyes, each one with their skin color. This caused Rin to be stunned and accidentaly went on the power of his flames to a critcal level, enough to injure, push back and make these girls went unconscious. Rin suddenly left.
A few hours later, the blue girl came to this place where she saw these other girls. The four girls suddenly recovered their mind and stared with angry faces at the blue girl. She ignored them however and continued her way.
