well probably thanos and odin could easily clap the army of kage but I do understand what your trying to say. As the common foot soldier asgard is just as strong as black widow. but the elite named soldiers are anywhere from being able to destroy a planet to a multiverse and most kage are able to destroy a country and at the very peak a small planet. If you do end up doing this Hela will end up the a good army.

true, at his peak he can destroy multiple solar systems

is this a translation or a fanfiction?

you probably already know this but this is for future readers. The Sefirah Castle relates to 3 paths fool, error and door these are metaphysical abilities, they don't have much destruction capabilties like magic in anime but are very OP. Lets talk about the error path it can deceive and steal all sorts of things. They can trick others with their eloquence, sleight-of-hand, steal their targets' Powerful or mundane abilities, decrypt, steal thoughts and intentions. an example of this would be the stealing abilty. Steal can steal anything for example in highschool dxd the bael bloodline can you the power of destruction you can take bael bloodline for yourself and use the power of destruction. those are the type of metaphysical abilities of the three path I would go into steal but it's already getting long.

Author all I can say is you will face backlash and some read will drop the novel but others will agree with your decision with the MC getting together with Bai Ning Bing. The most safe bet is just choosing the original or different love interest.

isn't naruto and bleach too weak of a world for hela, she will easily speed run it? if talking only about anime why not saint seiya or tensura because the top character will be on par with hela?

i don't about everyone else but this chapter sounded a bit Chinese

Again you need to read more. Normal 7 sense warriors can destroy stars, but Virgo Shaka can destroy multiple solar systems at the same time which is not the same as being able to destroy the universe.

Either you didn't read the manga or you forgot. Hades can't just destroy a multiverse he can destroy the highest form of a multiverse, which is in a higher dimensional structure than a normal multiverse also known as a complex multiverse.
