Since Black Rock Shooter ended some time ago, Miku fans haven't seen even a hint of the virutal idol in anime. That changed during episode 15 of Shinkansen Henkei Robo Shinkalion the Animation, or Shinkalion for short. The series stars Hayato Hayasugi, the son of a train history museum curator and follows his adventures when he finds his dad's secret train mech lab. Hatsune Miku effectively stole the show at episode 15 though.

Miku needs her own anime, and this proves it. In the show, she's seen as a megane-wearing tsundere with hobbies including train mech conducting and kendo. Other Vocaloid characters are seen in passing, making us wish for that Miku anime even harder. The clip above and some screen shots below should give you an idea of the level of awesome Miku can bring to an anime series of her own.

Note: I brought up the anime Black Rock Shooter in the beginning because the song Black Rock Shooter is sung by Hatsune Miku, and her overall design is based on Miku's appearance.
