Ok, well, I went out on a limb and bought it without knowing ANYTHING about this series (which is quite rare for me...I usually like to be a little learn-ed about a series before I invest in it), so I thought I'd give you a review as of volume 1 for anyone else interested.
What's the lowest age this title is suitable for? 16+
Violence Level 4
- lots of mech battles, but from what I've seen no blood.
Language Level 1
- I think I may have heard one swear word, but if I did it wasn't anything fairly memorable nor was it a reoccuring issue
Sexual Content level 7
- where to start with this...Rune's grandfather makes her dress up in sexy, scantily clad outfits with bikini style waistlines. Nothing was ever graphically shown, but....well she dressed like a female in one of those fighting games. Also, there's this running gag about how she wakes up in the morning with some funky costume on and can't figure out how her grandfather got it on her while she was sleeping. Personally I was not thrilled at all about the joke and what the innuendo was, although in the end they did have a sort of "explanation" that had to do with particles materialzing and such. I think there was also a section where the student council president made some comment about her panties.
Nudity 2
there's a page in the middle of the comic that has Rune nude and curled up into a fetal position--it's a transformation shot. It's not very detailed, but it's defiantely clear she's nude. I wasn't horribly offended, but I wouldn't let my little brother read it either.
Objectionable Religious Content 3
The whole premise of the manga is that there is a being called the "space queen" who rules the universe based on her will (Kinda like Cephiro's pillar for you MKR fans). Rune is supposedly this queen reincarnated. There's also a wizard, and some magical "holy circles" that are really like teleportals--they allow aliens from another planet to come to Earth.
Overall, I have mixed feelings about this series. On the one hand, it's got it's cute moments. Chat, for example, is adorable, and it's a fairly good bishojo plot. It's kinda interesting to see mech/sci-fi from a definately bishojo perspective. However....it's definately got its pitfalls, and it's drawn in a sort of retro style I don't find all that attractive. I may or may not get the next volume, but I hope this was helpful to you.
