The plans
It's been two days since he left the Yokai in his Dimension, now that he had left the class, he felt somewhat unusual just because he normally used to walk home with Irina.
He was in his thoughts until he felt a familiar presence.
Grayfia: "Don´t you have your guard down a little too much?"
As he guessed, it was Grayfia who appeared.
Yukio: "I guess ... is something wrong?" He asked her quickly.
Grayfia: "Did you forget about Rias' training?"
Yukio: "..." Actually, he forgot, but he was not going to say that. "No, where is it?"
Grayfia seemed to notice that he lied to her, but she just smiled and opened a magic circle, which they entered.
At least there was no one around to see such an act.
---
When he reappeared, he could see Rias, who was sitting, absorbing the mana from the air, he was surprised by her level of ability.
When she saw them, she got up and walked towards them.
Rias: "Hello Yukio-sensei." He could see a respectful smile that he had not seen before, he thought it was funny that after showing some strength she really considered him her teacher.
Yukio: "Good morning Rias-chan, should we start with your training?"
Rias: "Yes", apparently she had a lot of motivation, it would hurt me to ruin it.
He smiled innocently while letting out terrifying words for Rias.
Yukio: "In that case, today you're going to run around the whole mountain thirty times and I'll load you 30 kg on each leg and 40 kg on your arms."
Her face paled, she looked at Grayfia trying to get help, but she just stared at her.
Grayfia knew that when he said something for Rias´ training, they were not jokes.
So she followed the orders with a face of suffering and injustice.
For his part, he thought that he should start his plan, he was very weak and needed to strengthen himself. At this rate he could do nothing when something happened.
His first task would be to save Akeno and second to find strong servants, he knew the names of some who would be excellent to get.

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

He assumed that he could only see little information because she was not his servant, as to why the System only let him see one skill should be because he was the one who gave it to her.
Rias: "Did something happen, Yukio-sensei?" She asked him with red cheeks because he touched her head.
He ruffled her hair and smiled at her: "You've become strong, do you want to train mana?"
Rias nodded, and he took a look at Grayfia, who already knew that they would enter his dimension.
Previously he hesitated to let her in, but realized that she did not have any malice towards him, but only keeps that kind look.
Even so, he would not let them know that he can teleport to any place through portals from there.
So they disappeared again into a white portal.
---
Inside he could see a scene he laughed at, Grayfia froze as Yasaka did when she first came here.
On the other hand, Rias was in shock for something else, from a distance she could see a beautiful castle.
Yukio: "We'll train somewhere else, follow me." He pulled the two women out of their trance and they started following him.
During the tour, he could feel Grayfia's eyes that were curious about this place, she felt many nearby presences but she did not know exactly what they were because this place contained a lot of mana/ki/chakra/energy to be able to distinguish them.
He gave an internal sigh, he knew that Yasaka had a very good nose and knew that when he entered the dimension, it would not be strange if she came towards him.
Yukio: "Here it's okay, today we'll go into something different." He started to make a circle on the floor where he 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 in the air, this place had a lot of that.
Grayfia approached until she was beside him.
Grayfia: "Yukio-sama ... This place?"
Yukio: "What's wrong?"
Grayfia: "Where are we exactly? What are these presences?"
Yukio: "You can compare it to 'The Underworld' and 'Heaven', calling it a specific place would wrong, we are not anywhere on earth, it is a separate dimension, as far as presences are concerned, you will know soon."
What he told her was the truth, but then he felt a particular presence that was coming towards them.
In addition, this place was a separate dimension and that strange red portal where the auras that were on the other side of the dimension were felt.
He could see that on top of Rias' head a sphere of mana was forming, Grayfia was shocked at such an act.
He approached her back placing his palm on it.
Yukio: "Try to let every thread of mana enter in your body, just do it slowly and don´t 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 his part, he closed his eyes with his palm on her back watching each process with his [Magical Perception].
When he noticed that it would go out of control, he used his [Magical Absorption] to drain what Rias could not absorb.
---
Yasaka had smelled the scent of Yukio, so she headed towards him.
It did not take long and when she arrived, she saw him standing next to a redheaded girl placing the palm of his hand on her back, plus she could see a large sphere of mana over her head.
It was the first time her eyes had seen such a brilliant way of handling and increasing mana.
Her gaze traveled the place until she saw a silver-haired woman looking at her, it was not necessary to say that she already recognized her.
Yasaka: "The wife of Lucifer and servant of Gremory." She bowed respectfully, even if she was on par with demons of Ultimate rank, she did not want to bring problems to Yukio.
Grayfia: "Yasaka leader of Yokai." She stopped for a moment. "What are you doing here?"
Yasaka: "To tell you that, at least I should know what relationship you have with Yukio-kun." She was not going to say so easily that her 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 relationship ... he is under the care of Gremory and is the trainer of the heiress." None of them were going to say the whole truth.
Yasaka: "I see ... W-" She 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 themselves as if she had feline whiskers.
Her energy was triple that of when she entered and her beautiful red hair, became the same as blood, piercing the eyes.
As for Yukio, his right arm had dark marks as if a dragon was rolling, his eyes turned purple with dragon irises and his black hair at the tips turned 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 mana and only one word could be heard at that moment.
Rias: "I ... I did it!"
