Kazuna is a young man with a fairly normal life. He attends high school, lives with his surrogate family, and models for his somber love-interest Yaegashi's paintings. But recently, he has suffered several crippling attacks at the sight of blood - attacks which leave him incapacitated and out of control. Kazuna must now reunite with his sister who he has not seen in years, and discover the truth behind his family name and vampiric genes, before his bloodthirsty desires destroy himself, or others close to him.
The lead characters of Lament of the Lamb and Vampire Girl become vampires and it is the worst thing ever. They can't control their bodies, and feel completely helpless. Both manga also explore "replacements", creepy co-dependant relationships, and unearthing dark personal histories with a more somber mood and less action than most vampire stories.
Vampire Girl has a much more substantial plot, whereas Lament of the Lamb is pure atmosphere, and has a more interesting take on vampirism.
Years ago, a kidnapping incident left a pair of victims with lasting psychological scars: Maa-chan is prone to violent mood swings, while Mii-kun's pathological lying shrouds his life in mystery. Now, when the news begins airing stories of kidnappings and serial murderers, Mii-kun moves into Maa-chan's house, in an effort to protect this girl who he has been through so much with. But can he save her from herself?
Half serial murder mystery, half story about the relationship between two deranged/dangerous people. If you liked this interplay in either, check out the other. Also: blood everywhere.
Chiyuki is a young girl with a terminal disease. Near death, she meets a vampire named Touya and blackmails him into spending time with her; however, he doesn't drink blood because if he took a blood partner the partner would die long before him and he doesn't want to get hurt. When Chiyuki is dying he saves her life by having her drink some of his blood, because he feels even being with her for a little longer will be enough. She returns to school and forces Touya to join her there, where they discover that one of their classmates is a werewolf who is ashamed of being a monster. Both of them slowly become closer to Chiyuki because of her warmth, her will to live, and her non-judgmental love which heals the wounds from their pasts.
Hiromu Nishizawa can't figure it out – he seems to be the only one at school who remembers a certain classmate that doesn't seem to exist. Though he begins to believe he's going crazy, the boy then encounters a mysterious person named Vermillion, a man who bears a disturbing message: Hiromu isn't who he appears to be. Now, he must discover the truth about himself and his past – a past that spans decades and beyond...
Jumping between the past and the present, Omae ga Sekai and Million Tears are enigmatic stories about doppelgangers, immortality, reincarnation and memories. Our protagonists meet someone they were acquainted with far in the past but whom they do not remember. This person claims that our protagonist looks exactly like someone they've been searching centuries for.
Meanwhile, people are disappearing or being killed one by one. As well, an immortal being encourages his friend to turn someone into one of their kind as a companion for eternity. Slowly, the puzzle pieces of the past fall into place as our protagonist encounters more mysterious characters and begins having strange dreams. Tragedy strikes as our protagonist finally recalls who or what he/she truly is.
The art in these two series have a wispy, dreamy quality that lends to the melancholic feel. Story-wise, these two series aren't the smoothest in terms of transitioning smoothly. At times, it can be downright confusing. However, Omae ga Sekai and Million Tears excel at exploring the psychology of its characters and pondering some philosophical questions about love, life and fate. Godhood and the responsibilities of those with the power to create or destroy is touched upon in Omae ga Sekai. Million Tears expands further than Omae ga Sekai on this.
Of the two, Million Tears can be depressing but it has a more positive ending than Omae ga Sekai. Omae ga Sekai deals with more mature themes and has a grimmer tone. Not recommended if you can't handle complex plots dealing with again: doppelgangers, immortality, reincarnation and memories. Think of Tsubasa Reservoir Chronicles' 2nd half condensed into 2 or 3 volumes.
If you're planning to read Boku no Hitsugi de Bansan o or Omae ga Sekai wo Kowashitai nara, here's what you need to know:
1. There will be vampires and tragedy.
2. Boku no Hitsugi has interrelated oneshots set in what seems to be the European countryside several centuries ago and modern day Japan. Omae ga Sekai also switches between these two settings in present day and flashback sequences throughout its ongoing storyline.
3. Both series have a very melancholy feel to them. Most of your main characters are lonely nihilists or shoujo heroines that are soon-to-be broken birds.
4. There will be romance but this is not a love story.
5. You will flip over the last page feeling like you've been punched in the gut.
