Hoozuki no Reitetsu
|
Both have lots of cracky humor and random pop culture and nerdy references. They're set against dark backgrounds (hell, Cthulhu Mythos), though they are much more quirky than creepy.

Log Horizon

Both have a cunning adult male lead who tries to gain an advantage in his world via plotting, psychology, and alliances (rather than with physical force or fighting). The series are leisurely-paced, and set in pseudo-medieval worlds.

Kakumeiki Valvrave

Worlds where things are powered by the energy of human memory. Beware of using up too much - otherwise you might lose yourself. Both shows have lots of 'feels.' (Tegami Bachi is more for kids, Valvrave is for older teens and up.)

Psycho-Pass

Unsettling psychological stories set in the future. The female lead is a discontented participant in her society, but she accepts it, rather than try to change it. Their governments/leaders keep a terrible secret, and monitor and tightly control citizens' behavior in an attempt to create a utopia. Deviants are eliminated.
