Bleach

Kurosaki Ichigo is a 15 year old boy that has an ability to see ghosts/spirits. Because of his ability, he is able to meet a female death god (a.k.a Shinigami) named Kuchiki Rukia. To save his family and friends from unwanted soul-eating spirits (Hollows), Rukia transfers her Shinigami powers to Ichigo. As Rukia takes on a human shell, together they solve mysteries involving spirits and hollows until from the spirit world comes 2 other shinigamis explaining that it is illegal to transfer Shinigami powers to humans and Rukia exceeded the time limit to stay in the human world. After they sentence her death for breaking the laws, Ichigo snaps and swears to everyone he will retrieve Rukia by breaking into the spirit world.

Kuroshitsuji II

Well on a first note DON'T WATCH KUROSHITSUJI 2 WITHOUT SEEING THE FIRST SEASON!!! Trust me you won't get half the story line, and the 1st season is a good see too. Anyway, I've followed the show since episode 1 (season 1 of course) watched the musical, read the manga(btw manga and anime completely different story lines)and completed this season and what I really have to say is that... it's worth watching. (a bit of a warning ahead the ending is a bit disappointing, but this is just my opinion) On another note, to all you yaoi fans, this whole season is pretty much a fan service (so enjoy ^^). Anyway if you're a big fan of the show I pretty much recommend watching, if not well give it a try then complain about it later ^-^.
