Re: Fairy Fighting
I don't know Japanese, but the options are easy enough to decipher with Rikaichan, a little clearer than with Google Translate anyway.
複数妖精ステージ(多レズ)
"Multiple fairy stage (multiple lesbians)"
Sounds pretty self explanatory.
拷問モンスター(拷問器具で)
"Torture Monster Stage (in torture device)"
You get captured in a torture device. Bondage. Could be gore if it's similar to the Mad Scientist Eluku was thinking of doing before.
ゾンビステージ(複数で喰われる)
"Zombie stage (eaten by multiple [zombies])"
Also pretty self explanatory. A bunch of zombies tear you to pieces and eat you. Gore.
触手オンリーステージ
"Tentacle only stage"
A stage with just tentacles. As opposed to monsters with both tentacle and non-tentacle attacks.
獣姦
"Bestiality"
Pretty easy to imagine.
巨大モンスターの体内
"Inside the body of a huge monster"
Vore. Nothing hinting at what will actually happen to Tiki though, could be any range of things.
肉体改造モンスター
"body modification monster"
I haven't had more exposure to this fetish than I needed to decide I didn't like it, so I'm not sure what to expect here.
Personally, I'd like to see the "inside the giant monster" stage, since I'm not too hot on gore or body modification, and I find lesbian and bestiality stuff kind of boring. We've got vore already, but it'd be interesting to see stuff happen to Tiki after she's already swallowed, as opposed to it being just the SP finisher. The torture stage also sounds potentially interesting, as long as it's not gore.
Immortals don't re-grow limbs... That's why cutting off their heads kills them a-la highlander.
Depends on the fiction. There are many types of immortals out there.
