@Astaro For the High_End feats of Tensura WN, some of them are:
1) Moibus System is a Real-Life Black Hole Engine: and Rimuru has no problem interacting with its Event Horizon and Beyond:
2) Moibus System will destroy the Universe, but not anything else, as beyond the Universe we have the Gap between Dimensions: Yes, there is the catch that it will not destroy the universe in one shot, but it will very soon.
3) Rimuru's Beelzabub, which is quite inferior to his Final US: Azathoth, is comparable to the Moibus System. The reference that Beelzebub can destroy the Universe is made through the series by all High-Level Characters.
3) Veldora could temporarily suppress Mobius. Also, Veldora's Probability Manipulation is good enough that Moibus System, even should it destroys the Universe, can do nothing to Veldora. Only reason why he was having difficulty was that he was trying to save the World of Side-Stories. And for that he needed to supress the Moibus.
4) Time Stop In Tensura affects the Entire Universe and can stop the expansion of the Universe.
There are others as well, some of which directly State the Star System and Big Bang, I will post them afterwards.
And, nothing in Tensura stands upto Top-Tier of Toaru, if anyone says otherwise- They haven't read the novel.
Also, LN is a lot bonker than WN to the point LN makes WN seem tame in comparison, but unlike WN, where everything was happening randomly, LN has a system at least. and explains why the Planet and Universe hasn't been destoryed several times over.
