Oh, you like Pokemon as well huh, my favorite one is Mawile. It's really a shame that mega evolution can't be used in the later games but on Showdown, I have a pretty good Fairy monotype team with a Mawile in it for the National dex double format.

Japanese people actually don't use hiragana on japanese swords' name, only kanjis. I would suggest you to use this instead: 悪魔ノ破壊者 (Akumanohakaimono / Akuma no hakaimono)

Was that already a thing back in the 1900 in Japan? I'm not sure about japan but those inheritance laws were mostly in Europe and America at that time and Asian countries had their own laws.

I've watched it but it's been so long that I completely forgot what it's about and I don't even remember a single character from it.

A jacket that can devour anyone also doesn't make sense but the author decided it do and he even made it so that the effects are permanent while a devouring type devil fruit is only temporary. Also, mc's jake jake no mi was never limited to fiber, he can create a space inside him so it should be normal to be able to control space it self and maybe other things.

Tatsuya shouldn't. He is older than them but had to repeat a year.

Lol, that's true. We can also say it's the fanfic author's authority which allows him to change the anime's logic

Your point of view is completely biased. If earthquake itself can touch space, time or concept, shouldn't the jacket power be able to do it too? Like wearing the concept of death making him to be able to control death itself. By extension, should he be able to "wear" the concept of vibration too?
