I was in my thoughts until I felt a familiar presence.

Grayfia: "Do not you have your guard down?"

As I guessed, it was Grayfia who appeared.

Yukio: "I guess ... is something wrong?" I asked him quickly

Grayfia: "Did you forget about Rias' training?"

Yukio: "..." Actually, if I forgot, but I was not going to say "No, where is it?"

Grayfia seemed to notice that I lied to her, but she just smiled and opened a magic circle in which we entered.

At least there was no one around to see such an act.

---

When I reappeared, I could see Rias, who was sitting picking up the manna from the air, I am surprised by her level of ability.

When he saw us, he got up and walked towards us.

Rias: "h.e.l.lo Yukio-sensei" I could see that respectful smile that I had not seen, I thought it was funny that to show some strength I really considered his teacher.

Yukio: "Good morning Rias-chan, do you think we started?"

Rias: "Yes" apparently had a lot of emotion, it hurts me to ruin it

I smiled innocently while letting out terrifying words for the Rias girl.

Yukio: "In that case, today you're going to run the whole mountain thirty times and I'll load you 30 kg on each leg and 40 kg on your arms"

His face paled, he looked at Grayfia trying to get help, but he just stared at her.

I knew that when I say something in training, they are not jokes.

So he followed the orders with the face of suffering and injustice.

For my part, I thought that I should start my plan, I am very weak and I need to strengthen myself at this rate. I can not do it.

My first task will be to save Akeno, second to find strong servants, I know the names of some who would be excellent to get

When Rias finished his training, I was on the floor panting, I approached she and put a hand on his head.

I a.s.sumed that I could only see little information while I was not my servant, as to why I only let myself see a skill should be because I was the one who gave it to him

Rias: "Does something happen, Yukio-sensei?" I ask him with red cheeks because he touched his head.

I ruffled her hair and smiled at her. "You've become strong, do you want to train mana?"

Rias nodded, and I took a look at Grayfia, already knew that we would enter my dimension.

Previously I hesitated to let her in, but I realized that she does not have any malice towards me, but only keeps that kind look.

Even so, I would not let them know that I can teleport to any place through portals from there.

So we disappeared again into a white portal.

---

Inside we can see a scene of laughter, Grayfia froze as Yasaka did.

On the one hand, Rias was in shock for something else, from a distance he could see a beautiful castle.

Yukio: "We'll train somewhere else, follow me" I pulled the two women out of their trance and they started following me

During the tour, I could feel Grayfia's eyes that I was curious about this place, many nearby presences, I did not know exactly what they are because this place contains a lot of mana/ki/chakra/energy to be able to distinguish

I give an internal sigh, I know that Yasaka has a very good nose and knows that he enters the dimension, it would not be strange if he came towards me.

Yukio: "Here it's okay, today we'll go into something different" I started to make a circle on the floor where I asked Rias to stop "Sit in that place in a lotus position and try to gather as much energy as you can"

Rias nodded and sat down to channel the energy of the air, this place had a lot of that.

Grayfia approached me until she was beside me.

Grayfia: "Yukio-sama ... This place?"

Yukio: "What's wrong?"

Grayfia: "Where are we exactly? Are these presences?"

Yukio: "If you refer to him as 'h.e.l.l' and 'heaven', a specific place is wrong, we are not anywhere on earth, it is a separate dimension from him, as far as presences are presented alone"

What I told him was the truth, I felt a particular presence that was coming towards us.

In addition, this place was a separate dimension and that strange red portal where the auras that are another side of the dimension are felt.

I could see that on top of Rias' head a sphere of mana was forming, Grayfia was shocked at such an act

I approached his back placing my palm

Yukio: "Try to enter every thread of mana in your body, just do it slowly and do not worry I'll stop it if something happens"

Rias nodded with her eyes closed as a small thread of the sphere inscribed on her forehead.

For my part, I closed my eyes with my palm on his back watching each process with my [Magical Perception]

When I noticed that it would go out of control, I used my [Magical Absorption] to drain what Rias could not

---

Yasaka had felt the smell of Yukio, so he headed towards the

It did not take long and when he arrived, he saw him next to a redhead girl who placed the palm of his hand on his back, plus he could see a large sphere of manna on his head.

It was the first time his eyes had sung such a brilliant way of handling and increasing manna.

His gaze traveled the place until he saw a peliplateada woman looking at her, it was not necessary to say that he already recognized her.

Yasaka "the wife of Lucifer and servant of Gremory" He bowed respectfully, even if he was on a par with demons of maximum rank he did not want to bring problems to Yukio

Grayfia: "Yasaka leader of Yokai" He stopped for a moment "What are you doing here?"

Yasaka: "To tell you at least I should know what relations.h.i.+p you have with Yukio-kun" I was not going to say so easily that his faction was here, they could do something to Yukio

Grayfia: "Yukio-kun?" She frowned, but it was not the time to talk about it. "Our relations.h.i.+p ... is under the care of Gremory and is the trainer of the heiress." n.o.body was going to say that everything was complete

Yasaka: "I see ... E-" I was going to keep talking but both women felt explosive energy coming from the two children "

Their faces were surprised when they looked at them.

Rias had several dark marks on her body, some stretched to her cheeks, positioning herself as if she had feline whiskers.

His energy was triple that of when he entered and his beautiful red hair, became the same blood, piercing the gray eyes.

As for Yukio, his right arm took dark marks as if a dragon was rolling, his eyes turned purple with the dragon's irises and his black hair at the tips took a little gray that surrounded him with a dark aura all over the body.

It was momentary, but both women could see it, they soon returned to normal while Rias was panting due to the intense manna and only one word could be heard at that moment.

Rias: "I ... I have it!"
