Eden of the East

Recently, I have started watching a couple of anime on and off. One that I recently finished is Eden of the East. It is actually a short anime, but quite interesting. To give a sort of short introduction, without ruining the plot, the main characters are Akira Takizawa and Saki Morimi:.
Akira lost all his memories (self induced) and meets Saki during her trip to DC. He finds that he has a mysterious phone with 10 billion yen (it works sort of like a credit card). It also allows him to contact a concierge named Juiz who can essentially make any of his wishes come true (through physical means) Notable characters in this series include angelika,

Yutaka Itazu, who loses his pants,

and Kuroha Diana Shiratori

who is interesting for multiple reasons.
