Diehauser was happy at the moment because he got to talk to his sister and conflicted about her becoming pregnant behind his back. He chatted with his sister for some more time before cutting off the call. Diehauser thought that it's better if he didn't know her location for the best. And he didn't know if he should tell about Cleria to his family or not. If he said, they would be happy but knowing his father, he would confront Lord Bael about this which won't have a good outcome. But he doesn't want them to be sad about Cleria's death too.
And with that issue aside, Diehauser looked at the mysterious child in front of him. Cardinal-Bishop Michaelangelo. It was said that he is a ruthless child who kills the devils without mercy just like his grandfather. But the actual truth turned out to be the opposite. And according to his sister, he is trying to unite the three races. Diehauser respected that wish. Diehauser also wants to create a peaceful future for his unborn relative.
And the main issue is the King Piece. Diehauser's face became serious when he thought of it. Even though Diehauser is the Champion, he couldn't believe that this much corruption is going on without him knowing. And they dared to kill his sister just because she found out about that piece. Cleria actually talked about this with Diehauser before. She said that Ajuka Beelzebub had a secret hideout near Kuoh and that there is actually a King Piece. But Diehauser just cut it off saying that it was an urban legend and not to approach that hideout. And this made Cleria more determined to prove it. In other words, he is the one who put her in danger. Diehauser felt guilty about this. If only he believed her that day, things would have been different.
Anyway, he is now determined to stop those Old devils to do whatever they want. And he needs someone to help him. He looked at the boy in front of him.
"Cardinal-Bishop Michaelangelo, did you already expect my arrival to Kuoh?" Diehauser asked Mike while pointing to Touji.
"Not really. I guessed that someone might come and I was waiting for Underworld's move. I guess you could call me lucky since Mr.Champion is the one who appeared. Well, to be honest, I wanted one of the Maous to appear. But this is fine too. Anyway, call me Mike." Mike casually explained. Diehauser understood that if he was casually waiting for Maous, this child cannot be underestimated.
"Wait! What do you mean you expected this?! I could have died, you know?!" Touji interrupted the conversation by shouting at Mike.
"Relax... I was following you the whole time while hiding my presence. Ah, that reminds me. What was that comment you made about me hiding my presence? You had a good smug on your face at that time." Mike teased Touji about the time Touji mistook Diehauser's presence with Mike's.
Touji couldn't help but cringe at the comment. He made a mental note to never be confident about anything when Mike is involved. And Touji just realized something. If Mike is following all the time, then that means... "Mike... When you said that we should wait and asked me to do solo missions, you were using me as a bait to someone whose power level is unknown?!"
"Wow, as expected of Touji-san! You figured it out too fast!" Not only Mike didn't try to deny it but he also made a sarcastic insult to Touji. And Touji could only say one thing in response.
"Am I a joke to you?"
"No. You are the bait."
"That's even worse!"
Mike didn't care about Touji's complaints and started laughing. Even Diehauser couldn't help but chuckle. And here Touji thought that he is going to do something like fight along with Mike. But Mike was using Touji as bait instead. And the worse thing is that this is the same person that his daughter has a crush on.
"Mike, I thought you were a hero but you look more like a villain to me," Touji stated his inner feelings
"Well, if being a hero doesn't get the job done, I would rather be a villain" Mike replied without hesitation.
Diehauser is astonished by Mike's mentality but he respected it. He also thought that it's weird for a child to be this mature. Diehauser also doubted Mike's strength since he was even ready to face a Maou.
"Mike, how are you so strong? I don't sense any aura coming from you even now." Diehauser curiously asked.
"Ah, that's because I hide it in my body..."
"You what?"
"Wait a sec." Mike enveloped his body with a tiny portion of the holy energy in his body. "Do you sense it now? This is a very tiny bit of my power though."
Diehauser understood that Mike is a mastermind in controlling his holy aura. Mike normally condenses all of his holy energy into a tiny dense ball and keeps it inside his body when he isn't in heaven. And that ball powers him up from the inside without leaking the energy outside.
Mike developed this method after looking at Vasco's ability to fuse holy power into his punches. And Mike was like 'Hmm... Gramps is condensing the holy power outside, let's try to do it inside for fun.' And he succeeded just like that. When he showed the technique to his siblings, Michael and Gabriel lectured Mike for an hour. Because condensing that much energy into a ball so tiny would be the same as playing with a bunch of hydrogen bombs. Even Michael isn't capable of that feat. Forget the Vatican, Mike put the whole of Europe in danger that day.
Since Mike can control holy power easily, he can use the same method to make the holy power ball unstable and BOOM. Simply put, he can make holy-power bombs. They would be a nightmare for the devils. But Mike prefers to not use that skill since it leaves the trace of holy energy afterward which will gather a lot of attention.
Anyway, Diehauser decided to make alliance with Mike to get revenge at the Old devils. Mike sent Touji home. And now, it's only Diehauser and Mike. So, Diehauser asked without hesitation "What do you want me to do?"
"Isn't it obvious? I want you to take me to the underworld. There is a lot of preparations we need to make..." Mike instantly asked him to take him to the underworld.
"Hold on. Mike... It is not that easy. Underworld has a lot of things that are brought there in secret but you need a lot of connections to do that. I and even my father are not enough to do this. And the system to transportation to underworld is very strict."
Diehauser might be the Champion but his family just came out of poor conditions because he won the rating games. Belial family's only major connection is Zekram Bael but in this situation, he won't be helpful.
"Well, if we can't use connections, we will use skills..." Mike said with confidence.
"What do you mean by that?" Diehauser didn't understand.
"Hacking!" answered Mike while doing a thumbs up.
Mike's hacking is not limited to God's system and computers of the world. Given enough resources and time, Mike can completely hack any system other than the one in Heaven. Even that one is partially hacked by Mike. Mike easily understands the fundamentals of every system which makes it easier for him to hack. So, to sum it up, let it be a system, a magic circle, a magic barrier etc, if they are instant or needed for a less amount of time, it will be okay but if they are deployed for a lot of time, they are just asking to be hacked by Mike.
