^ Honestly? I'd have to go with the world of Kyoukaisenjou no Horizon. Sure, the world might end at any time, but magical technology has essentially eradicated hunger, poverty, and almost all disease. It's an pleasant, pretty place, with traditional architecture and baroque furnishings mixed seamlessly with tangible holograms and flying ships. Naturally, the world isn't perfect, and politics generally consists of powerful demagogues vying for control while the environment slowly decays into ruin; but for the average human citizen, especially seeing it from my 21st-century vantage point, I'd imagine it's a wonderful time to be alive. Alternatively, it'd also be nice to be part of the Neighbor's Club on Haganai.

v Conversely to the above, if you could bring any anime character (or small group of characters) to life and choose their relationship with you, who would it/they be?
