Electromagnetic Girlfriend is an eccentric little gem of an anime, absolutely packed with suspense, mystery, and adventure from start to finish. I went into this with the weirdest expectations because of the title, but not even 10 minutes in those expectations were flipped on their head, and I was hooked. Beginning with the story, it really pulls its weight considering just how short the show is with a scant 2 episode run. Without giving anything away, the setup is very out-there but soon builds itself up into this engaging, even surprising story, backed up by some great writing. The mysteries are so unique and detailed and take these turns that are just impossible to see coming. This aspect alone is incredibly impressive, and this anime's strongest point.
The art is very solid overall, with distinct character designs and a level of background detail which really brings the world to life, which in turn makes the mysteries more compelling.
The sound is also well-crafted, with impressive voice talent and accurate sounds of life, like footsteps on wet pavement or the buzzing of flies. This is all not to even mention the music, which adds this ethereal sense of mystery and danger to any given scene.
The characters that find themselves in these mysteries are also compelling, and act in ways that feel both classically styled for a mid-2000s anime and also grounded in pretty believable motivations, especially Juu's reluctance to entertain Ame's seeming delusions, or Hikaru's desire to protect her sister. Overall, Electromagnetic Girlfriend is a solid mystery anime, especially for how short it is, and is definitely worth a watch. Indeed, my biggest count against it is that there's not more of it, as even the manga itself is pretty short. Do not sleep on this, at best you'll love it and at worst there are worse ways to spend 80 minutes.
