Starting Monday, I read around 4 manga series, namely

Basilisk:

This is a really good manga. The story is basically about two rival ninjaclans Iga and Kouga at the beginning of the Tokugawa era. Unable to find a worthy successor among his grandsons, listening to advice from his personal advisor, he decides to break the peace treaty keeping these two clans from killing each other. Both clans are to choose ten ninjas and fight against each other to the death. Each clan is to represent one grandson and the new shogun will be decided by which clan survives.What follows is a bloody battle in which all 20 ninjas are killed. The different Ninja techniques displayed in this series are good but I feel most of the charaters are underdeveloped. They could've made this series a bit longer. My friend doesn't like it beause he feels it's too realistic but I felt it was a welcome change from all the unrealistic battles I've been reading about recently.

Trinity Blood:

This is the series that truly exceeded all my expectations. The story is about a world after Armageddon. For around 800 years, the Vatican has ruled as a major power . They are willing to use even a Krusnik(a vampire who feeds on vampires) to combat the threat of extremist groups led by Methuselah(vampires) and such. Thus, the Ax(the foreign affairs branch of the Vatican) sendsits agents abroad to exterminate Methuselahs who are causing problems. Instead of being portrayed as fiendish monsters, the Methuselah are portrayed as entities as complex as humans but with a great sense of pride and honour. They even have a whole empire. And, strangely, the Krusniks play a major role in the politics of this world(Abel Nightroad alias Krusnik 2 is the main character of the series and an AX agent; his sister Seth alias Krusnik 3 is the ruler of the Methuselah empire and their brother Cain Nightroad alias Krusnik 1 is the main antagonistand the leader of the Rosencruez orden which is the most powerful of the extremist groups). The manga is based on a series of novels by Sunao Yoshida who, unfortunately, died before he could conclude the series(refer Wiki for details). Although,I must say,The story'sreally great.

Hellsing:

Yet another vampire story. This manga is about the Hellsing organisation which combats the threat of vampires in England. Their secret weapon is a vampire named Alucard. What I like about this series isthe action. the series is pure action but also has a good story.

D. Gray Man:

Yet another good series. The story's about a guy named Allen Walker who joins the Black order, a group of excorsists who work to defeat the Millenium Earl, a phantom who is building an army of Akumas(or demons) to destroy the world. The plot seems cliched and the series seems highly influenced by Bleach and Fma but it's better by far than Bleach is or ever was. it seems to be a highly underappreciated manga/anime series but I would highly reccomend itto any fan of Bleach or Naruto.

Currently, I'm downloading Berserk and looking forward to reading it.
