That was every bit as random as I expected.
OP: "Crowds" by WHITE ASH
pretty optimistic about the technological advances we'll be making in the next year and a half. It's also set in Tachikawa - like Index and Railgun - a place that's become a sort of RL exemplification of futuristic cityscapes for the world of anime.
Tachibana Sugane (Ohsaka Ryouta, the Tsuritama carryover). He carries some sort of device that clearly has unusual properties, seeming to predict the movements of an unknown subject. Next up is Ichinose Hajime (Uchida Maaya) an impossibly genki schoolgirl with a love for notebooks and kawaii (and combining the two). On the roof of her school Hajime sees the mysterious J.J. Robinson (Mori Katsuji), who in his riddle-speak seems to suggest to Hajime that she's been chosen for something special. This is pretty routine superhero stuff, though handled stylishly - eventually Hajime pairs up with Sugane, who attends the same school (which has some of the most interesting school uniforms I've seen in anime, BTW) and she witnesses him in the act of doing his Gatchaman job, dealing with a MESS (explanation coming later). At HQ, he introduces her to the slacker Hibiki Joe (the very busy Namikawa Daisuke), the depressive two-piece wearing Utsu-tsu (Koiwai Kotiri) and the flamboyant O.D. (Hosomi Daisuke, also a Tsuritama veteran), the only one who seems to share Hajime's love of cute and genki nature. And then there's Paiman (Hirano Aya) - don't call him a Panda! - who seems to act as J.J.'s section chief in charge of the "G Team". There's also the requisite spiel about aliens threatening Earth, the MESS, and how the NOTE devices the Gatchamen carry work.
