Since he was a child, Kantaro Ichinomiya has had the ability to see demons; but one day, the young Kantaro was told of a goblin so powerful that it could vanquish any foe with ease. Intrigued, his search began. Now, in the present, Kantaro works as an exorcist, banishing demons who have possessed human bodies; yet still he searches – that is, until one day, he touches a mysterious seal and releases the legend itself! His name is Haruka, he's good with the ladies, and he can kick demon butt like no other; but can he help Kantaro raise enough money for his rent?
Kagome is a normal high school girl who falls into a well, transporting her back in time to the feudal era. Upon her arrival to this world, she mercifully unleashes Inuyasha, a half demon. As if this isn't enough, she also discovers that she is the bearer of the Shikon no Tama, a jewel of great spiritual power, a jewel which has just shattered into a million shards. Now, along with Miroku the priest, Sango the demon hunter, and Shippou the mischievious fox-demon, they must set out to find the Shikon shards and defeat the evils of the demon Naraku.
InuYasha and Tactics share the whole hunting down/getting rid of demon type things. Even though in InuYasha the main char is a demon who kills other demons to look for jewl shards, the style of the two animes is similar. In both stories, there are humans who can somewhat control the demons. Kantaro somewhat has a reign over Haruka just like Kagome and InuYasha. Both anime series have a light humor. I enjoyed both series and think if you like one, you would like the other. :)
Legend says that if the flesh of a mermaid is consumed, the body becomes immortal. However, with the small chance of immortality comes a high chance of being poisoned, morphing and mutating into a monster beyond comprehension. Yuta is a wanderer: one of the few who has eaten the flesh and survived, and lived to tell about it -- for 500 years. By chance, Yuta meets a young woman named Mana who also shares the same fate, and together, they wander the land, searching for a mermaid who can free them from their immortal lives.
Shizuru and Mizuki are two quiet sisters who have a foot in the world of the supernatural. While Shizuru can see the spirits and monsters who haunt mankind, Mizuki can't help but become possessed by them. Together, the duo live with their grandparents and are taught about the spiritual world from their grandfather, a powerful exorcist. In the serene countryside, the girls will learn about the ghosts and goblins that co-exist in our world, while also learning about themselves and their abilities.
If you find the many Japanese supernatural monsters, the youkai, fascinating, then there is plenty to enjoy in both Mokke and Tactics. Both series function as a catalogue (of sorts) of the rich population of different and weird supernatural beings of Japanese folklore. The approach to the spirit world is very different, in the two anime, but nicely complementary.
In Norse mythology, the end of the world was foretold as the final war between the gods, and its name was Ragnarok. In a twist on the lore, the god Loki finds himself exiled to the world of humans. Mayura, a girl obsessed with mysteries, ends up entangled in Loki's struggle to return to the world of the gods without realizing it, and meanwhile, the gods divide into factions. Some are willing to help Loki find his way home, while others are after his life -- the end of the world, the final war: Ragnarok. And in the center of it all is Mayura...
Plot-wise these two go hand in hand and revolve around a detective agency that solves supernatural-related issues. They both dwell on mythological (in Loki, Norse myths) and folklore-driven (in Tactics, Japanese lore) elements with a heavy dose of comedy (probably more so in Loki) and drama (especially in the latter episodes of Tactics).
In the streets of Tokyo, the nightbreed walk as humans, preying on innocent lives and feasting on innocent blood. There is one man who would put a stop to this: Shido, the Night Walker, whose blood is made up of the very thing he aims to protect against: the nightbreed. Along with his co-worker Yayoi, a green fairy named Guni and a clever young secretary named Riho, Shido and his detective agency take cases that would be otherwise missed and forgotten, to seek out the nightbreed and send them from whence they came...
