Well i'm currently on full Hellsing period...lol. And for those, who have completely NO IDEA what Hellsing is:

(ヘルシング, Herushingu, romanized as HELLSING in Japan) is a Japanese media franchise created by Kouta Hirano, which consists of manga, anime, soundtracks, and other collectibles. Hellsing chronicles the efforts of the mysterious and secret Hellsing Organization, as it combats vampires, zombie-like creatures called ghouls,a powerful werewolf, and other supernatural foes who threaten the kingdom of England. The name Hellsing is an alternate spelling of "Helsing", as in Abraham Van Helsing, from the Bram Stoker novel Dracula.

=Little descriptions of Story-line

Hellsing follows Alucard and police girl-turned-vampire Seras Victoria as they exterminate the vampires and other creatures of the night for England's Hellsing Organization. The Hellsing OVA is a closer adaptation of the manga than the Hellsing TV series.

Episode One of the OVA follows the manga's first Volume . It covers Seras being turned into a vampire, the introduction of the characters, and the first fight with father Alexander Anderson . There are some minor departures from the manga, such as inclusion of Seras' dream sequence with subtle super deformed aspects, and inclusion of Seras being welcomed by Integra, Walter, and Alucard (after the dream sequence she woke up to see Alucard by her side). These departures are not as drastic as the departures in the TV series. It should be noted that the OVA series features humor similar to that of the manga, which was not included in the TV series.

Episode Two of the OVA follows the manga's second volume. Dealing with the Valentine Brothers' assault on Hellsing's headquarters . It is slightly different, as Alucard's battle with Luke Valentine is extended, and there are a few scenes of the brothers individually killing Hellsing soldiers that were not in the manga . The last two chapters of the manga are also left out, probably since the entire episode is heavily action based, although they are seen as images during the credits. Omissions include the introduction of Pip, and Enrico Maxwell with Anderson. The Omake which premieres in volume 2 of the manga is also left out, which likely means it will not be seen in animated form.

Episode Three of the OVA follows the events shortly after where the credits of Hellsing Ultimate II ended. the introduction of the Wild Geese mercenaries, Integra's meeting with Enrico Maxwell, Alucard and Walter's discussion about Millennium, the mission to Rio de Janeiro, the massacre at Hotel Rio, and the duel between Alucard and Alhambra. In addition the scene with Enrico interrogating the priest from Volume Four was omitted and instead a scene with the Major from Volume Four was added.
