Yagaht

There is like five characters that come to mind with this description.

Why speech looks like it is in chat group? Even speech that shouldn't look like this...

Excalibur was never stuck in a stone. It was Caliburn. At least in Nasuverse. Real life legends tend to have different names for sword in stone.

In the case of Yukari? It's not an actual wank, I doubt about multiverse destroying, But one concrete universe? Without taking out all of it's parallel universes? She can destroy it with a flick of a finger. Granted, it will not be instant. It will not be very fast. But she can set off chain reaction that will, without shadow of a doubt, destroy one specific universe. Eventually. And she will in fact die while setting it off. About the whole limited time power up, they usually include it in the profile, in the weaknesses part... And well, power in this state is separate from character default state. Do you actually read profiles? Or you just skim power level and confirmed abilities? When dealing with power scaling, you need to employ actual critical thinking yourself, otherwise you shouldn't even bother. It's like watching news and believing them without verifying.

Yeah, don't really understand whole Rias hype train.

Author missed the iconic scene, of the message from the future, and operation Skuld explanation... Deceive your past self. Deceive the World. I wish you good luck, El Psy Congroo.

She is a manipulative, lying traitor. I don't know how anyone can trust her. She gained trust of real prince. Studied him, and then orchestrated his death. Even gloated to his face... How can anyone tolerate traitors?

Probably one of the most unrealistic parts of the whole outbreak. Somehow, internet died, in the span of 24 hours. All local, and not servers just... stopped. Mobile signal too, suddenly poofed. It doesn't work like that, at least not without professional sabotage.

EX is not the highest, it just means it cannot be quantified under this specific numerical system. It Exceeds the system. Technically speaking there is one rank higher. Which is ★. It means that there is literally NO number that can represent the rank.

Gotta say, screens don't matter. The only result of his actions, is that no one will be able to see in real time. Until they connect new screen. Footage is still on the server.
