In the mystical world of Shangri-la, demons and humans live side by side, watched over by a parthenon of ancient Chinese gods. But when normally-civilized demons start to go berserk, the gods require the services of Genjou Sanzo - a Buddhist priest with a magical gun, an evil-banishing scripture and a take-no-prisoners attitude. Aided by the ancient monkey god Son Goku, the half-demon Sha Gojyo and the demon exterminator Cho Hakkai, he sets off on a treacherous journey westward, with armies of demons, dark mages and angry gods all standing in his way...
Banishing evil spirits your favourite kind of anime? Than you should watch Tactics & Saiyuki. Both animes have some cool fighting scenes along with exorcising of evil spirits which will leave you breathless at the end of every episode craving for more.
Saiyuki and Tactics both have a fairly good, if somewhat meaningless story, and are both of good length. Tactics is a bit less guilty of the story culminating in a manner that makes one wonder if the story really needed to exist at all, and as an added bonus you won't feel the urge to kill the writers when it ends . . . because it doesn't have a sequel that is absolute garbage.
I can't really say I'm overly fond of the ED on either, but you get used to it after a few episodes in both cases -- and the mystery/boy-love theme is prevalent in both, without ever providing a decent fan-service moment in either (so people tested by the boy love in one won't be further tested by the second).
Over-all Tactics, I think, was slightly better, but both are very good.
An organization known to the dark side of the world as Chronos claims to desire world peace, employing the top thirteen assassins in the world known as 'Erasers.' They each have a weapon customized to fit their style, all made out of orichalcum ore, the strongest material available on Earth. Number 13, Train Heartnet (codenamed Black Cat) is the most famous and revered of the thirteen Chronos numbers, but in the light of a tragic event he has come to question his path in life. Together with Sven Vollfied, a struggling bounty hunter and a living weapon named Eve, Train takes up a job as a bounty hunter - all the while running from the other Erasers and Creed Diskenth, a crazed man whom wants him to join the Apostles of the Stars, a group made to destroy Chronos.
Tactics and Black Cat both revolve around a somewhat serious fellow and his band of miscreants as they go after various baddies. Tactics has a permanently lighthearted feel, while Black Cat is a bit more dark. Both have various monsters/creatures and a generally slow and plodding pacing and flow. I didn't care much for either of these, but figure if you liked one you'd like the other.
An akuma is a soul which has been brought back to life through sadness and despair with the powers of Millenium Earl. Their mission is to terrorize the earth and all who dwell within it. The Black Order is a group of Exorcists that have sworn to cleanse the souls of the akuma, and collect the substance known as "innocence". This powerful substance can be used as an anti-akuma weapon, and ultimately can help destroy the evil Millenium Earl. Allen Walker is a young Exorcist who has the ability to tell who is human and who is an akuma with the help of his cursed eye. Together with the Black Order, Allen must find all 109 pieces of innocence to protect the world and defeat Earl.
D.Gray-man has a more linear story with organized enemies, whereas Tactics is based on independent episodes with completely different opponents each time. However, both anime feature cool fights against monsters. The main characters are boys of about the same age, are haunted by their past, and are seeking a way to take advantage of their ability of seeing the unseen to save people and fight demons.
The world of the supernatural is a terrifying place, especially when youkai decide to seek revenge and punish humans for their careless ways. Luckily, help is at hand in the form of a young ghoul named Kitarou, who has taken it upon himself to protect mankind from malevolent monsters. With the help of his walking, talking eyeball of a father and his various spiritual friends – including the tricky and rather smelly Nezumi Otoko, the tomboyish Neko Musume, and the elderly Sunakake Baba and Konaki Jiji – Kitarou defends the clueless humans from soul-stealing Yasha, demons of death and many, many more.
Both GeGeGe no Kitarou and Tactics are steeped in Japanese mythology and the supernatural. Both also focus on someone preventing/exorcising spirits who are causing trouble for humans. If you liked one then definitely check out the other.
While Gingitsune is more slice of life and Tactics more mystery, both shows really emphasize Japan's stories and beliefs in a way that I find interesting and endearing. They also both handle the issue of what happens when a person can see these spirits and those around them can't, though Gingitsune takes a lighter approach to the issue.
