Cruel it is to seek the corners of lust bereft of light~ as if we hide from the sun itself. No creation is born with purpose despite our greatest poets whimsical musings - In our pointless existence I do find purpose, it is not to mark my brethren or dye the ground my hue, but it is to know if I want to mark my brethren at all and the color I choose.
I watch anime infrequently enough, and have such inconsistent sleep patterns, that I don't really have a specific time of the day/night. I mean, I have seen a descent amount of anime (probably around 500 or so series) but that is over the course of around 17/18 years. I don't consider it something I do enough to even count as a hobby or interest which I would mention to others. I would be more inclined to say manga, if nothing else because I actually own a substantial collection of it, in contrast to my nonexistent anime collection.
Need another option, 24/7
I mainly watch late-night because of Toonami. sub episode like One Piece are out at night. I have to get things done in the day for I can watch at night with no disturbance.
Usually i do it at night, mainly because that is when im awake. Im nocturnal, apparently. In my nocturnalness, i have grown to hate sunlight, so calling me a vampire wouldn't be to far off.
