Cirven looked at the attack that was quickly approaching him and sighed. He didn't like what he had to do next really but he knew he had to do it. This clone of him was not something that could exist with how it was and who was controlling it. Cirven placed his hand out just before the mass of white flames reached him and readied himself for what was next.
Back with the fake, he watched as the massive flame collided with Cirven. He was holding him now limp arm from the attack he had just launched while his face was in a grimace from pain. The massive ball of fire exploded causing the fake to smile. "I.. Did.. It.." He started to laugh out of happiness but stopped when he saw the flames were disappearing. "What the hell?!" He couldn't understand it. He had hit Cirven right? There was no way someone could just be fine after that attack. He then saw what was really happening. Cirven was absorbing the flames into his body. "No.. No.. NO!!" The fake started to run towards Cirven out of anger still holding his limp arm.
"I have learned a few tricks that they can't exactly just give a clone, you know. Plus I'm not exactly the same person as I was in the past like how you are." Cirven had absorbed all of the flames and then aimed his own hand at his fake in a similar way as the fake had done earlier which caused him to stop in shock. Wait.. You got to be kidding right? The fake was completely shocked by the similar stance. "Thank you for allowing me to gain my old fire abilities one last time." Cirven then fired off a similar massive ball of flame as the fake had done so earlier which even then still completely caught the fake off guard so much that he didn't move.
The flames collided with the fake and exploded, completely enveloping him in the Demon Slayer flames. After the attack the flames had covered the buildings nearby and most of the sandy road between them. Cirven was able to shoot off a version of the attack that was not as destructive to the surroundings. He then walked to the place where the attack had hit to see a burnt fake of himself on the ground. "You.. Really are.. The real Cirven.. I cannot measure up to you it looks like.." Tears formed in the eyes of the fake and Cirven did not respond. The fake laughed lightly while coughing a bit with it. "It was always.. Pretty ironic.. Huh? A demon.. Using a magic.. In order to kill.. Demons.. Way too ironic..." The fake stared up to Cirven and then the sky behind him as his last words came out from his mouth. Cirven sighed and leaned over to shut the eyes of the fake and then turned away from it as he moved to go and help the others.
