So who's singing the opening song? That would be でんぱ組, a brand-spanking new unit made up of four lovely DearStage girls. You read that name right, denpagumi (loosely denpa group). They are 100% unabashedly going for the 1-2 punch with this name, which is either refreshing or daft, depending on your opinion. Official Denpa no Sekai position: I am loving every fucking second of it, and it would be a crime against humanity if the denpagumi girls don't get a shot at a full-length album.
Which brings us to the ending theme 「Star☆tin'」, which was not only also composed by Koike, but performed by his new protégée 月宮うさぎ (TSUKIMIYA Usagi (yes, usagi as in rabbit)). Together they form ULTRA-PRISM, which they describe as 2.5D POP, but there's definitely a lot of denpa (their description, not just mine!), cheery picopico as well as typical Idol stuff thrown in for good measure. The fact that Usagi is a former Happy! Style member, yet such a hardcore otaku adds a nice touch of silliness to the whole thing. The following video will give you an idea of what the new unit is shooting for.
There's a good chance these songs might remind you of UNDER17, that's because ULTRA-PRISM is meant to be a "reboot" for old chap Koike. Their debut mini-album "Inspiration" was actually released at C75, but hasn't seen much exposure outside of a couple great articles on MOEYO! and GETCHU. Honestly, if it wasn't for the split CD with denpagumi, I probably wouldn't be talking about ULTRA-PRISM right now, and that would be a damn shame! Look forward to more ULTRA-PRISM coverage in the near future... *hint* Usagi is a bit of an anglophile.
Finally, GWAVE recently announced a new U single featuring two songs, the OP and ED themes to FrontWing's upcoming fourth entry in their 「魔界天使ジブリ－ル」 eroge series. No samples so far, but U has been in charge of all previous theme songs, so you can get a pretty good idea of what these should sound like based on prior art (Episode 1, Episode 2, Episode 3). Although U will be at the helm, as she usually is, Koike will provide guitar solos to these tracks, as he usually does. The release date is April 23rd 2010, but FrontWing will most likely release the opening video well before that. Stay tuned for more LA LA LA LA LA LA LAs!
