「O2」 by Orange Range was one of the OPs I was anticipating, but I'm a little disappointed with the single. The "full version" of 「O2」 just doesn't quite deliver.. At some parts, their voices are too soft, just like this OP single. At least the MV is entertaining.. ^^;
The other songs, 「春紫苑」 (Harushion), and 「世界ワールドウチナーンチュ紀行」 (Sekai World Uchinaanchu Kikou), are FAIL, IMO. 「春紫苑」 just sounds gay, while 「世界ワールドウチナーンチュ紀行」 is eight minutes worth of techno beats.
