Two brothers, Y/n and Issei Hyoudou. Issei Hyoudou died when he encountered a fallen angel. Issei got reincarnated as a devil but Y/n volunteered to join in order to protect his brother from enemies. But the two of them didn't know the power that's...
After retrieving the Divine Blade, I went back with the others to continue training. I planned on not telling then about the blade yet. I was now back and only saw Lucy without her helmet sitting on a rock waiting for me.
Lucy: "You're back."
Y/n: "Yeah, I just felt a large power scale. That's why I went out to check it."
Lucy: "I felt it too, I think the whole supernatural world felt it. That was pretty scary I should say."
Y/n (Thoughts): "That's how powerful the blade is?"
Albion: "I told it's more powerful than the True Longinus. Even though that weapon pierced God but the Blade is a planet buster level."
Y/n (Thoughts): "That is pretty scary."
Y/n: "So Issei and Tanin already went out to train?"
Lucy: "Yeah, I was just waiting for you so we can start ours."
Y/n: "Okay then, let's sta-"
Then a powerful aura suddenly exploded as me and Lucy put our helmet in and flew towards where it was located. Once we arrive there, our eyes widen of what caused it. It was Issei in his Balance Breaker?

Lucy: "Woah!"
Y/n: "Did he finally achieve it?"
Albion: "I think so, I can feel Ddraig's happiness from up here."
Nova: "I think he is proud of his perverted host this time."
We flew beside Tannin and watched Issei as he was staring at his new power in awe.
Issei: "Did I finally do it?!"
Tannin: "I think you did."
Issei: "This is awesome!"
Ddraig: "For once, I am proud of you."
Y/n: "Me too. What did he do to achieve this?"
Tannin: "I just told him focus on what his goal is and dig to that goal even deeper to break through his shell."
Lucy: "So that means."
Y/n: *sigh* "He tapped into his pervertedness even deeper."
Tannin: "I'll train him even more so that he can hold that form even longer."
Y/n: "Okay, I'll go ahead and train Lucy. We still have a week before we go back."
Time Skip
1 week later
We were flying back towards the Gremory mansion both three of us in Balance Breaker. Tannin was behind us following slowly. Issei and Lucy have improved greatly throughout the training as I was also training to wield the Divine Blade in private so no one could see it. We landed and deactivated our balance breaker.
