Mystery

Supernatural might refer to something mythical, mystical, bizarre, or something outside the bounds of accepted reality. There's a shadow of mystery often found in shows involved with this genre. Supernaturally oriented titles are often steeped in folklore, myth, or urban Legend. They may involve strange or inexplicable phenomena, Psychic Powers or emanations, and/or ghosts or other fantastic creatures.

Supernatural

Shounen

The thriller is a genre of fiction in which tough, resourceful, but essentially ordinary heroes are pitted against villains determined to destroy them, their country, or the stability of the free world. The hero of a typical thriller faces danger alone or in the company of a small band of companions. The protagonist may be a law enforcement agent, a journalist, or a soldier, but typically he or she is cut off from the resources of "their" organization. More often the hero is an ordinary citizen drawn into danger and intrigue by circumstances beyond their control. (Source: Wikipedia)

Thriller

Psychological media delve into mental or emotional states of a character in the midst of a difficult situation, letting you observe them change as tension increases. Internal monologues are a key feature, allowing narration to delve into a character's mind, revealing their innermost ideas and motivations - even as they may be driven to the brink of sanity.

Psychological

Anime that fit in the alternative present category usually have technology and society that is very similar to ours, but with differences in both, history and culture, which sometimes are blatantly obvious, but sometimes harder to place; this one can at times be very subjective.
