A Lesson...

~~~ With Issei ~~~

So many things have happened to Issei in the last few days. First, he was asked out by a girl, and she tried to kill him, only for THE Rias Gremory, who turns out to be a devil, together with the whole ORC members, and she reincarnated him into a devil as well, and then Rias asked him if his childhood friend, Yuuji, is alive, to which he simply called him on the phone, and seeing that he's alive, he was tasked with a new mission: To tell Yuuji to come to the ORC.

So he waited for Yuuji at the gate, and when he showed up, Issei was about to approach him, until he saw a familiar black-haired girl locking arms with Yuuji.

His eyes widen in fear, and his whole body started to shake as they got closer until the girl's eyes landed on him, and she smirked and said:

"Well well, look who we have here. It's little Issei-Kun..."

Hearing her speak, Issei understood that he's not dreaming and Kate really is here, and without even checking out her breasts, something he does to every girl he meets, Issei screamed in fear:

"It's the English Monster!!!!!!!" he screamed and ran away into the school building, drawing the attention of all the students around.

~~~ With Yuuji ~~~

Yuuji just sighed as he watched Issei run away.

"Oh, it looks like he ran away. I wonder why?" said Kate

"Like you don't know. You were the one who tortured him every time he looked at your breasts..."

"But, a perverted beast needs some discipline, so she could be tamed... Besides, I only did that because you are the only one allowed to look and touch my breasts~~~" Kate said and hugged his arm between her breasts. As they walked through the gate, they could hear the students around talking about them:

"Is that the rumored Lone Wolf's girlfriend?" a female student said

"Good, now the girls will stop looking at him, and we have more chance..." a male student said

"I'm so jealous of her! Look at her! Everything about her is perfect! And she even gets to be with a hot guy like him!" another female student said

"I'm so jealous! He gets to have this hot girl as his girlfriend!" other male student said

"...They're annoying..." Kate said with a frown

"That's how high school students are. You'll get used to it too if you spend as much as I have spent being around them" Yuuji said, and the two of them sat on a bench, as there was still time before class will begin.

"No thank you. I have it enough with adults. Anyway, you felt it too, didn't you?"

"...Yes. It seems that Gremory wasn't only looking at me, and now she got Issei. In a way, it's good, because he now has someone else who can look out for him, but I'm sure that Irina won't like it too much... how's she doing anyway?"

"Well, last time I checked on her, she's still at the same church, together with Shidou-San, and recently, she received a new partner, who is a natural-born holy sword user, and I've seen her training with none other than the Durandal"

"Durandal? So Vasco Strada has given his weapon... I guess that his age is finally catching up to him... you should go. Class will start soon"

"But I want to be with you more!! And I don't have anything else to do, so I'll get bored for sure!!"

"Then, why don't you take Shou, and you two go play with the fallen angels? I couldn't prevent them from killing Issei, so at the very least, I'll punish them for it. But don't kill them, since I don't intend on becoming enemies with the Grigori. I never confirmed whether they are rogue or not, so capture one of them, torture them a little, and then question them. I want to know why they are here, and if they are still affiliated with the Grigori..."

"Okay! I'll see you after school!" Kate said and gave him a peck on the lips, and then left. After Kate left, Yuuji made his way to his class, and as he sat in his seat, he was approached by Rias and Akeno, who both were known as "Kuoh's Two Great Ladies", and both were in their third year, in the same class with Yuuji. Both were also a part of the ORC, with Rias as the president, and Akeno as the vice-president.

When they got to him, Rias asked:

"Good morning, Hayama-Kun. I want to talk with you about something, so would you like to come to the ORC during the next break?"

"No"

"Why not? I'm sure it will be worth your time..." Akeno said in a sultry tone and locked her arms under her breasts, emphasizing it. However, Yuuji just sighed and averted his gaze, saying:

"Because I'm not interested. Now leave me alone"

"But-" Rias was about to say, but then the teacher entered the class and the lesson began.

~~~ With Kate ~~~

"Are you sure that they are here? I can't feel anything..." said Kate as she stood in front of an abandoned church, where the fallen angels were supposed to be.

"That's because they're so weak, that you can barely feel them. I can't believe that Issei was killed by one of them. If he just used his brain to think and tried to work out a little, instead of thinking with his dick, then maybe he would've unlocked his Sacred Gear, and he would've beat them easily" said Shou

"If you say so..." Kate said, and the two approached the entrance and opened the door, and saw the three remaining fallen angels. Two females and one male.

"What are you doing here!? Get out, before something will happen to you!!" shouted the male

"We're here to deliver you something..." Shou said, and then opened a pocket dimension, and Raynare's body fell out of it. Then, he created a barrier around the church.

"Raynare!?" said one of the females

"And that's not all. She also tried to kill my boyfriend, but I never had the chance for revenge, so instead, I'll make you guys suffer..." Kate said and started to emit a powerful dark aura, that scared the fallen angels.

"Let's get the party started, shall we?" Shou said with a sinister smirk. They were going to enjoy this...

~~~ With Yuuji ~~~

Yuuji was sitting in his usual spot, by the tree, during one of the breaks, when he was approached by Yuuto Kiba. Yuuto approached him, as a crowd of girls followed him, but they stopped when they got closer to Yuuji.

"Hayama-Senpai, I wanted to ask you if you wanted to come to-" Yuuto started to say

"I've had enough..." Yuuji said and stood up, and then grabbed Yuuto's shirt and pulled him up, so his face was in front of Yuuji's face, as Yuuji was taller than him. The act scared the girls that stood close by, and they quickly ran away.

"I'll tell you one last time. I have no intention of coming to your little clubroom, so tell Gremory to stop asking, and if one of you will ever follow me around again like the white-haired girl has been doing lately, I won't be as merciful..." Yuuji said, dropped Yuuto, and walked away.

~~~ Time Skip ~~~

After school was over, Shou waited for Yuuji outside of school with the car again, and Yuuji entered, and then asked:

"So?"

"Well, they were sent by Azazel to only observe Issei, but then received two other orders from Kokabiel. One was to kill Issei, and the other is to extract a Sacred Gear out of a nun, who will be coming tomorrow. They were also told to only take her Sacred Gear, and leave her body in the church after they were done" Shou explained

"Good. We need to take a little detour. Drive to the abandoned warehouse on the outskirts of the city. Gremory didn't listen to my warning and decided to send her familiar to follow us... she needs to be taught a lesson..."

After they arrived at the warehouse, they parked the car and entered the factory. The familiar didn't have a choice but to descend, so it could look at them through the windows, but as soon it got to one of the windows, it was met with Shou's smirking face, and it couldn't react before Shou knocked it out...
