A/N I hope you enjoy i be posting this every other week randomly through the week
Issei was in the fight against loki when he got real mad for what he did to Rias and Issei snapped and lost all sense of reason Rias try to calm down Issei but he would listen issei anger past Ddraiger power and the juggernaut drive at the this point issei would kill anything that got in his path issei instantly appear in front of loki and punch in the gut he keep punch until a surge of power that came from issei amorged changing issei body not of a dragon something mix with a dragon and a demon it was truly terrible and scary Rias was stock of the appears of issei right after issei gather energy to his palm powerful enough to kill Loki in one shot after the battle issei disappeared Rias tried to look for him but she had no luck she was sad she return to the occult club afterword and everyone ask where issei was but she couldn't answer because she pass out of exhausting.
When she woke up she looked round for issei only to remember issei was gone akeno and the other asked where issei was Rias didn't know. Few days later Rias is sad that issei gone hmm where could issei be rias look around the underworld and still couldn't find him she later went back to her normal life but she was desperately hoping issei would return. One day Rias noticed a familiar aura during school she realized it was Issei she ran out of class following the aura. Ussei is that you turn around issei look like a demon for story he had black scale and his eyes were glowing but rias didn't care what he looked like she was glad to see issei again. Issei instantly rushed at her grabbing her and flew at high speed away with her when Rias passed out. When she woke up she was completely naked. Where am I in the underworld or the dimensional rift? Rias noticed issei was nowhere in sight. Issei later appears to return to a form that looks human.
Issei where have you been i missed you. Rias I couldn't come back but I want to see you because I love you Rias. Issei, why would you tell me now when I hadn't seen you in months. Rias I will give you a choice you either can stay here or I will return you back to school. Issei, why don't you come back with the others who are dying to see you anyway. Rias I can't return if I do my power will go out of control and I'm afraid that I will hurt someone that I care about. Rias if you leave I will evenly lose myself but I can't stop you from leaving. Issei's eyes right after turning green and causing a lot of pain and black scales started to appear on his body. Afterword Issei passed out and his whole body was bloody and clover in black dragon scales. Rias tried to wake Issei up but anything she did didn't work. All she could do now was to hope and wait if Issei woke up for days until he was unconscious until he woke up gasping for air.
Issei are you alright you scared me when you passed and started to bleed everywhere. Aww i'm fine it just a little cut and it happens at the worst time to instantly heal itself and wounds that were once there were gone. It started when I fused with my sacred gear but i don't think it complete yet or i'm dying. Issei what happened to Ddraig. Well Rias his and my soul fused together and nothing really changed I can still hear in my head. But issei it isn't good if this keeps up you don't know what will happen. I know Rias but i can't risk leaving the dimensional rift again. Then why don't I go get you help and bring them back here.
Impossible this is a realm in the dimensional rift that only I can enter. Rias i'm fine really i just need some rest. Rias didn't want to leave; she knows the others are worried and looking for her but she couldn't leave Issei; she knows if she did he might die. For days she watches issei and his body continues to change more and more hoping when his evolution is over he will be alright after what felt like a month's finally wake up.
Rias how long has it been since I was out. At least a few months issei. The other must be beyond worried issei tried to move but he could his body felt heavy and exhausted. Issei don't move you must still be weak just rest. Issei and Rias sleep together and for hours a little comes upon them.
Akeno and others, sure that Rias was dead, check the underworld and the human world but they could find her and couldn't sense her aura. A few months ago Akeno and the others heard Rias ran out of class and went to go find her but no luck. They know she could be far away so they check the school grounds but there was no luck they couldn't find her. After school the check again look for Rias they already lost Issei they didn't want to lose another close friend. After they couldn't find her they ask her brother if he knew where she was but no luck she was missing.
