Everyone was looking at Issei. The power of Heavenly Accumulating Strike was no joke. It was able to exit the atmosphere of the Earth and enter space. However, that's all everyone saw, but to Issei, he saw how insane the power was as it hit the moon and nearly made it move off course. Thankfully, Issei held back enough that it only dented the moon…Okay, it had a new large crater that people would question when they saw it.
"H-Holy crap!" Issei-II said. The power of the person beating him was more insane than he thought. 'Oh shit! Does that mean if I don't do as he says, I'll end up like Vali?'.
Issei-II was looking at Vali on the ground missing half his body. The sight of Vali made him shiver. Issei-II now knows how much Issei was holding back against him.
Issei then approached Vali and started healing him, but not with Divine Healing. He didn't deserve it. Although Issei wasn't using Divine Healing, the magic he was using was strong enough to regenerate Vali's missing body, but the pain that Vali was feeling wasn't going away anytime soon.
'Ddraig, do you think you'd be able to tank that hit?' Issei-II asked. He looked at the glowing orb of the Boosted Gear. 'Oy! Did you hear me? I asked, can you tank that hit?!'.
[Tank?! Why don't you go and tank it?! Do you have a death wish?!] Ddraig shouted. He saw it clearly. The attack was meant to let Vali survive by making it veer off course at the last minute. [Vali is only barely alive because that man has no intention of killing him. I saw the attack change course at the last second. Even in my prime, I doubt I would come out unscathed if I was hit by it].
'It's that powerful! And to think he made such an attack look casual for him,' Issei-II said to Ddraig. 'What do you think, Ddraig? Do you think it is a simple ability for him, or is it something that can only be done once?'.
[No, from the way he made it look to the way he acted casually, the attack he showcased doesn't seem to be hard for him to repeat] Ddraig said. Dangerous. The Issei from another world is not someone to be trifled with. [Issei, you are unlucky to have gotten the ire of such a man. I don't know why, but your perverted nature irks him].
'Ddraig, what am I going to do?' Issei-II asked. He was afraid of getting his ass kicked again. Although each hit he reached was healed instantaneously every time, the pain was still lingering until now. 'He seems to not like me at all. But I haven't done anything to him'.
[Hmm…If you want to know why he seems to hate you a lot, why don't you just ask him?] Ddraig said. That was the best idea he could come up with. [I mean, he doesn't look that unreasonable after beating the shit out of you. I think his initial hatred for you has gone down]
'Are you crazy?!' Issei-II shouted. He was staring at his Boosted Gear. 'What if I asked and he beat me up again? Am I going to have to go through the same treatment as before?'.
[You have no choice] Ddraig said. There was no other option of finding out. Ddraig looked at Raynare and Serafall, but he wasn't sure if they knew the reason for Issei's hatred. [That's your only option of finding out. Unless you have some sort of mind-reading ability]
'I don't have such a thing,' Issei-II said. He looked at Issei and sighed. 'I guess I have no choice'.
Issei-II took a deep relaxing breath before he approached Issei. The closer he got to Issei, the more nervous Issei-II got.
"Uno…? I have a question that I was hoping you could answer…." Issei-II said to Issei. The moment he met with Issei, Issei-II felt his existence was no more significant than an ant. He gulped, but he was already facing Issei. There was no turning back. "I want to know why you seem to hate me when you've only met me today? Aren't we the same person?".
"The same person? Hmph! I'm nothing like you," Issei said. He looked at Issei-II, and irritation seemed to be seen in his eyes. "Let me ask you this. When you do your degenerate acts, do you ever think about your parents?".
"What do you mean?" Issei-II asked. He had a confused looked. "Why would I think of my parents when I do something like that?".
"Looking at you really irks me," Issei said. He looked at Issei-II with scorn. "Don't you ever think of how hard and traumatising it was for them to have a child? Twice they had a miscarriage. And on their third time, they finally succeeded, but the child they got would go around doing horrible acts such as peeking and sexually harassing women.
How do you think they feel when your school tells them that their only son is a sexual deviant? Do you ever think of that?
Another reason is your uselessness and inability to work hard yourself. When you failed to protect Rias during the Rating Game, did you ever think of trying to push yourself to become stronger? No, you relied on Ddraig to give you power.
I didn't mind that, as it was an emergency, but did you ever try to better yourself after that event? Did you ever try to train so hard that you nearly collapsed so that what happened with Rias would never happen again? The answer is no! You won't do anything for yourself but peek at girls. You wouldn't do anything to work hard unless you are told and forced to do so. You have no drive to better yourself.
Before the event of your failure to help Rias in her Rating Game, you were too weak to save Asia, but after that event, you never did anything to train until it was ten days before Rias' Rating Game with Riser. Do you have to be told by someone else to do something before you decide to better yourself? Why can you do it on your own? Do you understand now why you irk me so much?".
"What can I do?! I'm not as strong as you! I wasn't born with your kind of power!" Issei-II shouted. He looked at Issei and scowled. "I don't have a cool ability to control time like you. I don't have immense strength like you do! I have to rely on the Boosted Gear to get stronger!".
Issei then punched Issei-II in the face.
"Stop with your damn self-pity!" Issei shouted. He was now angry. "Did you think I was born strong? Of course not, you fucker! I had to work myself to the bone to reach where I am today! Unlike you, it only took me a moment to realise how weak and pathetic I was back then.
In my world, when I failed to protect Shuri and Akeno when they were being attacked, something inside of me snapped and made me realise that I needed to be stronger because this world will not tolerate the weak who are involved in the Supernatural!
One moment of realisation was all it took for me to train harder and harder each day! So that I can gain the strength to protect the people that I care about!
What about you? You have had the realisation that you are weak and pathetic multiple times now. Yet, you have never trained to better yourself. All you do in your free time is watch porn and do deviant acts to women".
After saying his piece, Issei left with Raynare and Serafall. Issei-II and the others that heard what Issei said contemplated the things they've done so far. None of them has tried to better themselves. They've all waited for something to happen before they try to improve rather than improve themselves so that nothing bad can happen.
Issei, Raynare and Serafall were still in Draconic Deus Prime the following morning. They can't go back home until a month later. So, to waste time, Issei thought about messing with Kuoh Academy. He thought about going to Kuoh Academy and pretending to be Issei's cousin or something. It was possible since Issei and Issei-II aren't a 1:1 look-alike. Issei was taller, more muscular and had a different hairstyle. Plus, the mannerism of Issei was comparably distinct from Issei-II as he doesn't exude lecherous vibes.
In Kuoh Academy, Issei was standing at the gate, and people were looking at him. They feel that they've met him but couldn't put their finger on it.
Murayama and Katase arrived at the gate of Kuoh Academy. They saw Issei and were going to avoid him, but he seemed different. The two ladies wanted to leave the pervert alone, but they were curious why he looked different from his usual self.
"Hey, Murayama. Don't you think that Issei looks different? As if he was a different person," Katase said. She wanted to approach Issei and ask him directly, but he was too much of a pervert.
"I know what you mean, but what I'm curious about is that he seems taller than usual. Is it some sort of late growth spurt or something?" Murayama said. The Issei that she was looking at wasn't Issei-II. Thus, she thought that he was taller than usual.
The closer Murayama and Katase got to Issei, the more they thought that he was a different person. Why? Because Issei seemed to have gotten taller and taller the closer they got. That's right because Issei is six-foot-two-inches tall while Issei-II was shorter at only five-foot-seven-inches.
Issei looked at this world's Katase and Murayama. They looked weaker than the ones in his world. He thought it was probably due to Issei-II not having trained them in kendo. After all, in DxD Gacha, Issei has taught Murayama and Katase whenever he had the time.
