Klein talked to Shunsuke and got some information from the future, including the exact day when the organization would attack Japan and take 90% of the people with superpowers... There is a person in the organization who can wipe memories on a wide range, the only downside is that he faints right after, so they plan on using this guy to wipe out memories of 90% of Japan's population which would cause a Reality Rewriting event that would cause 90% of Japan to forget that their families, friends, or even just people they knew. That memory would be replaced by something else, like make people believe that some of them died, which would make some of them die in reality because...
There's something really powerful about humanity. Belief is something that can rewrite reality, if someone believes another person is unbeatable, that person would become unbearable if there's a Reality Rewriting event... And what is reality rewriting events?
Well, when something happens and that is not enough to break reality, it will change it, which will make Reality be Rewritten. Like if Klein uses [All Mighty Powers: Erase (SSS)] to erase a concept like sadness or even happiness, that thing would not exist anymore, which would make considerable damages to reality but not enough to destroy it! Then reality would have to adapt to this lack of happiness/sadness and all historical events, future events, memories, almost everything is redone to adapt to this reality. Some exceptions may register information about the world pre Reality Rewriting, which can make that object anomalous, and that object/person/thing becomes a Memento which is another entirely different story.
Going back on time also counts as a Reality Rewriting event if done right, or else it will become a Timeline Swap or Reality Destroying event. These two are similar but different at the same time, but both occur when time is involved, but they are essentially different, and also a Reality Destroying event or End of Reality Scenario can be achieved in several ways, but a Timeline Swap is achievable only by temporal based abilities or items.
Klein was lost in thoughts, really focusing on memories and information he had that he could do now... If he erased the person who can mass wipe memories, he would prevent a Reality Rewriting event that could doom Japan, which was something really serious, but he needs to know who the person is so he can erase them from existence... And there's the catch, Shunsuke only knows that it will happen, and there is no register on the database about this person. So Klein has some time to find the person who has the power to mass wipe memories from people, so he can prevent a Reality Rewriting event that will possibly change a lot of things in Japan!
Klein will have a hard time... Maybe he can buy more time with Max's rewinding power, but that would be not very usable because of the risk of a Reality Rewriting or a Reality Destroying Event, but they can certainly use Max's power to buy time.
Klein suddenly heard Max's voice in his head saying: "Sean had some trouble but he won... Barely. He is knocked down now, but he won. The guy he fought against had Pyrokinetic powers and burned his body badly... He didn't want me to intervene for some dumb reason but now he needs healing." As soon as he heard that, his wings expanded, six wings Previously he was using only 2 wings and used 6 wings when he is in a rush, which he is now. His wings glowed in golden light as he flew right out of the house, the roof was destroyed so he easily flew high and found where Sean was, when he landed beside him he was that his body was 80% black with burned marks... Klein sighed at his student's stupid decision and used his [Meta Powers: Healing (B)] to charge Sean's body with energy and try to create new cells to replace the burned ones.
Soon Sean's skin began to fall and being replaced by new skin. The boy was completely naked, his whole body was reconstructed by Klein's power, which mutated and evolved from [Meta Powers: Healing (B)] to [Meta Powers: Full Regeneration (A)]... Which was something incredible. The power to fully recover someone's body from any injure, disease, or any harmful effect on the body (Not including soul, mind, and others). This was somewhat OP too because Klein can use it to make other's bodies stronger as well. "He should be fine now... Just get him some clothes though, won't want him to be embarrassed about it." Max nodded her head and proceeded to drag Sean's body with her. Authorities may arrive here soon but Klein can deal with them easily with a [Mental Powers: Suggestion (A)].
Just simply suggest they leave and report that it was an accident in the old abandoned house. With some reconstruction of the landscape and tampering, it can be easily made into an explosion site, where some shit blew up on the old house's basement and gladly no one was hurt...
-Scene Break-
"Sir." A man wearing black clothing with glasses on his face looked at his superior, who was a scientist. "We may have found some lead on the Wicked Angel's location. It is not certain but Subject-069420 was lost today in Japan. His mission was to track and kill the Time Traveler who arrived... Subject-02 was able to detect its temporal tempering in Japan, where Subject-069420 was killed." The scientist didn't even look at the man as he had his eyes in a daze, looking at something else. "Subject-012969 was able to detect the location of the Time Thief and we're sending our agents to capture and secure the target if possible." The man ended his report and suddenly his body vanished, the scientist who had his eyes in a daze blinked and his eyes seemed to focus more on the papers in his hand that was left by the man who just vanished.
"Great news I see... I hope Subject N-0-A would be able to deal with the Wicked Angel..." Little did the scientist knew... Subject-0-A was no longer under his control but already gone.
