  The day, I brought Rias and the others to an isoted training ground. To ensure uninterrupted training, they had all taken a leave of absence from school. Since Rias was the territorial Devil of Kuoh Town, such arras were easily made.

  "Kyoya, how are we going to train? Do you have a pn?" Rias asked curiously.

  As soon as Rias asked the question, everyone looked at me with anticipation. After all, I had promised to signifitly increase their power within a week.

  Devils had long lifespans, so their prew incredibly slowly. Issei Hyoudou, the protagonist of the inal story, had to sacrifice his own lifespan to drastically increase his power in a retively short amount of time. This showed just how difficult it was for Devils to increase their power.

  If anyone else had made such a cim, they would have dismissed it as impossible. But knowing my personality and past aplishments, they unditionally trusted me. Otherwise, they would have been far more skeptical.

  ...

  "Before we start training, I'd like to have a little spar with Rias," I announced.

  "What? With me? Why?" Rias asked, fused.

  The others were also puzzled, not uanding my iions.

  "Don't worry about it, Rias. Think of it as me getting a feel for your current strength. Hit me with your stro attack. Don't worry about hurting me." I requested.

  "Alright, if that's what you want, Kyoya. Here I e." Rias warned.

  Rias activated her [Power of Destru], a crimson aura emanating from her. She spread her Devil wings and unleashed a powerful bst of destructive energy towards me.

  Boom!

  A loud explosion echoed, and a cloud of dust and debris filled the air. When it cleared, a giant skeletal figure was revealed—[Susanoo].

  Rias's destructive bst hadn't even scratched it!

  Everyone was stuo see that I was pletely unharmed, not even a hair out of pce.

  After all, this was the Gremory family's signature [Power of Destru], yet it hadn't even made a dent. It was hard to fathom just how strong I really was.

  "I cede defeat, Kyoya. You're way to. It's insane!" Rias said, feeling a little dejected.

  [Ding! Task pleted! Host received a Red Grade gift bag! Opening the gift bag. gratutions, Host, for obtaining the Magic Pohysique Enha Card.]

  Just as Rias admitted defeat, the system notification for task pleti in my mind. That's right, I had used this mock battle to plete the Red Grade task that I had gotten from Rias long ago.

  "Kyoya, you're such a bully. You were this strong, but you still made Tomoe-san and Kiba fight you." Akeno pouted pyfully.

  Kiba just smiled wryly and didn't say anything, though he did look at me with a hint of exasperation.

  "Hey, don't misuand. I wasn't this strong back then. Don't get the wrong idea!" I said, feeling a shiver run down my spi Kiba's gaze.

  "!!!!"

  "Kyoya, are you saying you reached this level of power in such a short amount of time?" Everyone was shocked.

  "Of course. Otherwise, how could I promise to increase your powers? Now do you believe me?" I said, a fident smirk on my face.

  "If that's the case, then I'm even more excited about the training." Akeno's smile grew wider.

  "Agreed! Please train us rigorously, Kyoya-senpai!" Koneko's eyes sparkled with excitement.

  "No problem. Let's start by addressing Rias's bottleneck." I looked at Rias.

  "Rias, ygest problem is your agic power. You 't sustain high-iy battles for long. Your [Power of Destru], in terms of pure destructive force, is nearly unmatched among Devil s in the Underworld."

  "But your mastery of it is still insuffit. That's something you o work on yourself, and I 't help you there. But I help you with yic power problem."

  "Hmm... mastering the [Power of Destru] isn't easy. Even Onii-sama struggled with it. It's impossible for me to make signifit progress in just one week." Rias sighed, a little disced.

  "You're wrong about that, Rias. Your brother is hiding his true strength. He may be a Maou, but his power has reached the level of a Transdent/Super Devil. His mastery of the [Power of Destru] far surpasses that of the previous Freat Satans." I said with a grin.

  ...

  Sirzechs ied the [Power of Destru] from his mother's side, the House of Bael. He could press his [Power of Destru] into incredibly powerful spheres and trol them freely.

  Currently, he holds the title of Lucifer, one of the Freat Satans.

  He was one of only three Devils who had transded beyond the level of a Maou (the other two being Ajuka Beelzebub and the leader of the Khaade, Rizevim Livan Lucifer).

  In fact, Sirzechs had even unleashed his true form, which terrorized even the God of the Underworld, Hades.

  ...

  But Rias, at her current level, had almost no ce of reag that level. But with me around, reag that level would be smooth.

  "Transdent? Kyoya, what's a Transdent?" Everyone was fused by the term. They had never heard of it before.

  "Well, it's not surprising that you don't know. I'll expin. A Transdent is someone whose power surpasses the Maou-css level. There are currently only three such Devils. Other examples include the Thunder God Thor, Shiva, and Zeus. They're all Transdents."

  Everyone was stuhey hadn't realized that there ower level above Maou-css!

  And they were even more shocked to learn that Sirzechs was hiding such power. Even Rias was stuo learn of her brother's true strength.

  After all, the beings mentioned were all renowned gods from various mythologies! God of Destru Shiva, the Thunder God of hology, and so on.

  It was no wohey were shocked!
