Issei was at a rating game battling Sairaorg the strongest youth devil. Issei was taking a final showdown with the young devil. Both of them standing apart from each other.

Rias was behind of Issei seeing him with admiration.

Sairaorg spoke, "What is your purpose?" Questioning Issei before the last fight.

Issei stood in shock for a moment. His opponent was asking his purpose for the fight.

Issei spoke, "I...I.. I want to show my king that I can protect her!"

"Very well I will make my dream true. Let us mark history!" Sairaorg spoke with a grin. 

After saying those words Issei felt regret that he couldn't express his love for Rias to the world. It was because of the fallen angel that broke his heart and couldn't bring himself to confess the girl he loves. Yet all the time he want to confess his love but his mind was reminding him of the fallen angel.

Then Issei charged at Saiarog and as the other did the same. They began to throw punches and kicks sending louds booms sounds. Issei felt small tears form in his eyes. After a few minutes Issei was barely able to win . He was on his knees with blood on his face.

Issei spoke in low tone, "I was able to win, but I wasn't able to confess my love."

Then Issei collapsed to the ground. Rias went to Issei seeing such state.

The announcer spoke, "Team Germory has won the match!"

Then Issei was taken to the medical bay. Issei was unconscious for couple of weeks. To Driag surprise no one visited Issei from Germory peerage except Sirzerks and the higher ups.

Issei was in his mind scape training with Driag.

Issei was painting catching his breath and spoke, "I'm glad I was able to win for Rias."

Driag spoke, "Yeah. I can feel your potential."

"You mean you understand the power of oppai?!" Issei asked excited.

Driag responded with a chuckle, "No partner your will to get stronger. I'll need therapy after this." After Driag wanted to break down in tears.

Issei looks down for a moment then raised his head with a smile.

Issei spoke, "I will for Rias and my friends!"

"That's I'm wanting to hear." Driag spoke.

They prepared for a another duel. Driag felt sorry for Issei that no one from his friends visited him yet he wasn't able to bring the subject up.

As time passed Issei was busy training with Driag before he woke up. Issei prepared an a attack and jump at Driag while boosting his power. Out of nowhere in mid air Issei felt his chest having a heart attack.

Issei spoke in pain, "Argh!"

Issei fell to the ground holding his chest with his hands. Driag began to worry for his friend condition.

Driag shouted, "Partner!"

"It hurts! Argh! Why?!" Issei spoke with pain.

Issei felt his heart was getting stabbed several times. With each stab he yelled in pain. While Driag began give his aura to Issei in hope it will ease the pain.

Despite Driag efforts nothing was helping Issei with his pain. Driag looked out of Issei body if anyone was hurting him, but there was no one at the hospital room. He was getting worried for Issei health.

After a couple hours Issei pain stopped eventually. Driag was watching Issei for any sign of side effects. After Driag finish giving his aura to Issei. Issei body was turning into a dragon body.

Driag asked worried, "Are you okay partner?"

Issei was getting up then sat down still holding his chest.

Issei responded with bit of pain, "Argh. Yeah it hurts but it felt like something was stabbing my heart. Driag do you think I over did it?"

Driag responded, "No you did not partner. That pain you experienced came out of nowhere. I checked the room and no one was there."

Issei spoke, "Yeah maybe... argh!"

Issei lied on his back holding his chest with pain.

"It hurts!" Issei exclaimed.

Driag was very concerned for his partner. Driag started to give him aura to his body once again as Issei was clenching his fists.

Issei spoke, "Driag.. argh! End my misery! Argh!"

"I can't partner. You must hold on the pain." Driag spoke.

"Have argh ever felt how argh.. I feel?! Do you have argh.. any knowledge?!" Issei spoke.

Driag started to think deeply but couldn't think of anything. He felt sorry he couldn't help his host.

After another few hours the pain lowered and Issei was trying to stand but his legs was failing him.

Driag spoke, "Okay partner. Seem the pain is gone."

Issei spoke, "I hope this doesn't again." Issei gave a small smile.

Driag spoke, "Oh about time. You going to wake up. Let's hope is nothing bad with your soul."

Issei spoke, "Thanks for being there for me despite you couldn't help. Can't wait to see some oppai." With a perverted grin.

Driag could only whimper hearing his partner words. 

Then Issei started to wake up with feeling ache all over his body. Probably he hadn't move for a good while. Issei noticed he was in a hospital room.

Then he heard a familiar voice, "Finally you awake."

Issei turns his head and it was Sairaorg sitting next to him.

Issei gave a small nod and saw it was just only him in the room.

Issei asked, "Where's everyone?"

Sairaorg stood up and sigh and responded, "Rias and her peerage are your home waiting. The leaders a bit concerned about you think you were in a coma like a month."

Issei was surprised that he gone for that long. He wondered if he worried Rias to death. Issei tried to get out the bed but his body started to failed him.

Sairaorg placed his hands on Issei shoulders and spoke, "Woah. Easy buddy you hadn't moved your body for a month. Let your body get used to it. Rest for now."

Sairaorg sat next to Issei and spoke, "It was nice fight out there Issei."

Issei chuckled and spoke, "Yeah it was. Sorry I had to for Rias."

Saiarog spoke with a grin, "It's not your fault but we will have a rematch someday."

Issei smiled and looked at the ceiling. The two were quiet enjoying the bother hood. Then they would speak about their dreams. As Issei spoke his dream his heart felt heavy.
