Hell's not ice, either. Don't get me wrong, the cold absolutely sucks, so a case could be made for it, but there's always a way out.
A case could be made for somewhere like, say, a jungle or swampland to be hell, thanks to the many varieties of ways to inflict pain, suffering, and death, but that's not hell, either.
Nor is there any city bad enough to qualify as hell.
True hell, then, is what?
Hell is water.
Especially given the Irony behind that. (It's an Ironic Hell to me.)
...Yeah, uh. Rough day at work. But I'm sure lifeguards everywhere agree with me, you don't know hell until you've been a guard.
With that said, I figured I should elaborate on a detail I said yesterday about Ruby. I mentioned she has a forbidden art 3--it's called Dark Messiah, with her calling herself Black Ruby within. It can only be accessed from Dark Ruby, because it is unleashed by pulling her hairtie for her ponytail, and letting her hair loose.
This unleashes what effectively is her inner demon, accessing her FULL vampiric powers and then some. She gains a fancy custom armor, her fingers become talons, her gloves turn white, and she gains demon eyes. (Think Inu-Yasha's full-demon form. Those eyes? Yeah, she gets them.) Not to mention, her teeth turn into fangs. I already told you what she could do in that form, basically being everything vampire, only better. (She can even hover above the ground, though not very far up--a few feet at most.)
But what she actually is, that's a bit more complicated. Basically, in Dark Ruby form, Ruby retains full awareness of everything she did while in that form: Dark Ruby is still Ruby, just with Ruby's inhibitions slightly weakened. Black Ruby is closer to being a Superpowered Evil Side, something she theoretically could use from day one yet holds back on as much as possible. Because Black Ruby has no inhibitions AT ALL, doing whatever it is that pleases her the most.
This makes her rather dangerous. After the transformation has finished (because Ruby can only keep that form for so long), Ruby will retain full memory of her actions and what she's said...but unlike Dark Ruby, the rest is a blur. She has only a sense of what emotions Black Ruby felt (mostly for her own protection given the sadism), and no memory of what her thoughts were when she was Black Ruby. (Again in contrast, Ruby remembers every thought and emotion she had in Dark Ruby form.)
So it's not quite like she's a different person. When going into Black Ruby form, she doesn't feel anything changed except a sensation of being, "Me, except better". (For certain definitions of better.) Which is pretty similar to Dark Ruby. It's coming out which gives her that sensation of being a different person.
I think this conveys the difference between Dark Ruby and Black Ruby fairly well. Dark Ruby's the same as Ruby, just Ruby slightly changes her attitude to be harsher. Black Ruby is mostly the same, but her lack of inhibitions means her mind is a seriously dangerous place to be, enough that Ruby only retains part of her experience as Black Ruby.
Naturally, this means she doesn't use it that often. (A common trend in the series. The more powerful, the less seen.)
Of course, I think at some point I need to lampshade how Ruby gains new powers as the plot demands, but given that Red Hood Rider takes place in the Rubyverse, a universe filled with SUPERHEROES, it's generally a justified trope especially given the setting.
