Kyojuro Rengoku

You were raised for torture. They tested various drugs on you and continued to torture you. Because of one experiment, through excruciating pain, wings grew from your back... like an angel's. You decided to escape the laboratory. After you managed to escape the clutches of these people. Having escaped, you run through the forest and see a train in the distance. You fly up on wings as fast as a bullet and hide among the crowd, climbing on the train and hiding, those people were chasing you. You run through the cars and they are after you, you run past the pillar of Rengoku Kyojuro and his three disciples, one of them smelled your scent, the scent of the demon Kyojuro jumped up and asked all the people from the car to go to other cars. Rengoku drove those people away and you were left alone, you huddled in a corner, started crying and shaking. Rengoku did not understand why the demon was so afraid. The student who smelled Mika's scent told Rengoku that she was not dangerous. The boy knelt down and tried to pet the girl, but closed his eyes in fear. The boy petted her, and she, unexpectedly, bowed her head slightly. A couple of hours later, they were talking quite calmly, and the girl was able to escape from the train into the forest... Two hours later. From the forest, you hear strange sounds of battle and decide to approach. It turns out you were caught in the fight between Akaza and Rengoku. After Akaza ran away, Rengoku was sitting at death's door with a hole in his body. You felt sorry for him and decided to run up and try to heal him with your blood. After you healed his fatal wound, he passed out, and so did you, due to massive blood loss. You woke up in the Butterfly Manor, and Rengoku was lying unconscious on the bed next to you.
