Xin look at the girl and said," You're too weak, you should practice more if you want to defeat me"
The blue-haired girl embarrasses bow and walks back at her friends.
Raiser angry stare at Xin and said," You stinky boy, I did not expect that you're strong that you casually defeat my pawn"
Xin smiled at him and said," I can casually defeat you too, so you don't need to be shocked ~"
"You don't need to taunt me, I will beat you, shithead, in the rating game!" Raiser said.
"If you can, but don't get scared after the rating game chicken man, I want to see if your fire really is the best in the underworld," Xin said.
"You will see," Raiser then takes all his peerage back to the underworld.
Venelana was shocked, she saw him move but she never felt any energy or power from that attack.
As if he only used his physical strength in defeating that Riser peerage, Venelana starts to mystify this boy.
Rias said," Okay we only have 10 or so days before the rating game, and we are only 6 while Raiser has a complete set of devils piece"
"We need to train if we want to defeat them, and Xin-kun will going to train us"
Xin wry smile," I'm going to train you guys?... why not you do it, after all your the king"
"No, you're the one whs going to train us, as I can see you're stronger than me and I feel that you can help us to get stronger before the rating game," Rias said.
Rias look at her mother and said," Okaa-sama, you can go back now maybe you still need to do something at home"
Venelana shook her head," No, I'm going to stay on you guys until the rating game"
"And I want to see how you going to train by this boy"
Xin helpless said," Okay, our training will start tomorrow morning, go to the park that i usually train that pervert dragon and Koneko"
"Why not go there together, after all we are already staying at your home," Akeno said.
"I said that for Kiba not you girls"
After that, all of them go back to their own class while Xin starts to plan what kind of training he will make for them.
...…..
Early in the morning Rias and her peerage want to go together with Xin, but Xin actually left first to prepare something for them.
When Rias and her peerage arrive at the park, they see a gigantic dome-like barrier that encloses the whole park.
Venelana looks around and sees that the people actually avoid going inside of the dome, but the way they move is actually normal.
As if avoiding the park is natural for them, and they don't have any reaction to what they are doing.
Then Melan appear with Issei who is walking slowly as if he is carrying something heavy, she looks at them and says,"..... Master said that you guys need to enter this dome and arrive at Master's favorite meeting place for 15 minutes… "
Rias thought," 15 Minutes is too long, maybe we can arrive at him in a couple of seconds"
Her peerage nodded to, they thought how far that usually place that Xin staying they know that if they all dash they will arrive in seconds
Melan then gives something for them, a blue and red bracer, she gives the blue bracer to Akeno and Rias while the Red bracer to Kiba.
"You need to wear this first…... and then enter inside.... " Melan said.
"What's this?" Rias asked.
"Prez, that is the training weights of Xin, I don't know the effect of the blue bracer but the red bracer is for gravity training," Koneko said.
Koneko show her red bracer and they notice that she actually using 4 of them at the same time, she said," The pervert-senpai is wearing 1 too"
When they look at Issei, the first thing they notice is he looks so tired early in the morning and the bracer that he is wearing too.
Kiba asked," Why does he look tired?"
Issei look at them and said," You don't know what kind of trouble you guys in, that stupid man is a devil and my little master is a demon lord, this thing can't remove even i used everything i know"
Koneko nodded," He is right, this thing cant remove, at first you feel somehow irritated because of the gravity but eventually you will be fine"
"Then why does he look tired even though he is already using this device for a long time?" Kiba said.
"He is human, of course, he will get weary fast," Koneko said.
Kiba suddenly remember that Issei is a human, he was amazed by how he can persist doing this every day.
Rias said," Let's enter"
All of them nod and enter the barrier, the first thing they notice is their body suddenly becoming heavy while; their demonic power is being suppressed.
Melan stood at them and said,".... Master first training menu for you guys is... to follow me... that's all"
"And for Issei-san…. master reminds you that if you can't follow me... you can use your sacred gear..... "
Then Melan slowly starts to walk, while the others start to follow them, they feel sluggish and almost strip because of the gravity around them.
Venelana who comes with them is amazed, she can feel the power suppression inside of the dome-like barrier.
And not only that, something actually purifying her demonic power and strengthening it.
Just like other children, she feels the weight but not that much like them who are wearing special bracers.
Venelana starts to get curious about the boy that her daughter likes, she only feels that he is a normal human, but seeing this thing. She knows that he is more than that.
