Aug 18, 2016 - If you're talking about legal sites, Netflix and Funimation have the English dub. Though it appears the latter only has seasons 2, 3, and some OVA episodes.

Kuroshitsuji (Season 2) – The stage of Kuroshitsuji II opens on the life of Alois Trancy, the young heir to the Trancy earldom. Though he is privileged now, such was not always the case for the hot-tempered boy. Kidnapped and forced into slavery at a young age, he was eventually rescued and returned home, only to have his beloved father pass away soon after.

However, there are certain individuals who doubt Alois’ story and legitimacy. And rightfully so, because things in the Trancy household are not as they appear, starting with Alois’ black-clad butler with supernatural abilities, Claude Faustus. Who exactly is the mysterious Claude, and what connection does he have with Alois? Amid the web of lies and deceit running rampant in the mansion, the bond between Alois and Claude will be.

Sebastian Michaelis is a demon of the highest order with almost unlimited power and style. Ciel is the remaining heir to the Phantomhive manor, determined to uncover the truth behind the death of his parents. Drawn to Ciel's side by his cries for vengeance, Sebastian forges a contract with the young Phantomhive heir: obedience and servitude to discover the faces of the murderers in exchange for Ciel's soul. Now bound as Master and Butler, Ciel and Sebastian return Phantomhive manor to it's glory in service to the Crown, drawn to investigate strange happenings, murders, and intrigues at the behest of Her Majesty, Queen Victoria. Handling the manor are Ciel's ever-faithful employees: Finnian, the youthful gardener with incredible hidden strength; Mey-Rin, the near-sighted maid who keeps a handy arsenal hidden away; Bardroy, the incompetent American cook who can find more than one chemical use for flour; and Tanaka, the steward. It is unclear if anyone in the manor is aware of Sebastian's demonic powers/persona besides Ciel, but that hardly seems to matter. Also stopping by is Ciel's blonde, bouncy, somewhat oblivious cousin by marriage, Elizabeth.

Fond of any and all things pink and cute and engaged to Ciel, Lady Elizabeth wants nothing more than to bring a smile to her dearest cousin's face again. In the city of London, while investigating a string of suspicious deaths, Ciel calls upon Undertaker, an enigmatic figure fond of sleeping in coffins and requesting jokes in exchange for information. Along the way, they also meet the Death Gods in charge of harvesting souls, in particular William, the tedious manager of the Grim Reaper Dispatch, and Grell Sutcliff, the sharp-toothed effeminate Grim Reaper as fond of Sebastian as he is of himself. Through twists and turns and horror an fantasy, the Phantomhive household fight the good fight for Queen and country, all to re-establish the good name of the Phantomhive household. And in the meanwhile, Sebastian will attend to Ciel's every beck and call with poise and flash and style. Because, after all, he is one Hell of a Butler.
