I really like this opening due to its vector graphics and for its precise depiction of the series. The story is about a boy who is considered a god in the 2D world, who later ends up using that power in the real 3D world. And just like your typical harem show, the introduction starts off by emphasizing the roles of its lead females. However, the transition from real world to fantasy world becomes a lot more evident about halfway when it decides to throw in a load of vector animation - precisely depicting its electronic theme.
