that's what i wanna know! why can inuyasha go through the well? and at the start, centipede woman went through, and yura's hair did, but no other youkai have gone through? lol, imagine if naraku went and destroyed tokyo!
And the lack of youkai in the future...i always decided to think of it as an alternate world rather than the future. , but then, trying to think of reasons why there couldn't be any, i came up with this idea i think im going to use for a fanfic as well as some originals.
it's kinda stupid, but fun. here's what i hought of:
vampires existed, like, in euprope or soemwhere, and having such long lifespans, they came up with technology a long long time before humans did, and set themselves up a little country of their own, and developed more technology, eventualy figuring out how to repress youkai abilities, and so they killed/enslaved the youkai all over the world, coming to attack all japan's youkai shortly after the shikon no tama gets completed. so thats why we dont have youkai running all over the place. and these vampires live in the burmuda triangle, and force youkai into creating barriers so we stupid humans don't really notice anything much weird there or see they have a massive island there. And from there, they secretly rule over our entire world! and what if it all gets ruined by inuyasha or someone, and the world is full of escaping and pissed off youkai all of a sudden?
i've got so many ideas in my head for plots using this premise...a story of some kind will certainly end up being written, but, naturaly i'll explain the whole vampire idea better in my story than that long winded, ncoherent types rant i just wrote.
