In the present, Japan is under assault by murderous creatures known as Aragami whose origin and purpose remain unknown. The fate of Japan and the world itself lies with one young woman named Momiji who bears the burden of the Kushinada -- the one who must be sacrificed to silence the Aragami forever. With the help of Mamoru Kusanagi (a human and Aragami hybrid), and an agency filled with firepower-toting bodyguards, Momiji must use her Aragami-sensing powers to help save mankind; but will she ultimately have to lose her own life to save the lives of so many others?
I believe the person who wrote the manga for Sazan Eyes and Blue Seed is the same. Both anime involve a young protagonist who encounters a mythical element/power/figure; They are then entrusted to use their newly found power to fight the forces of evil

In times of olde, humans live in constant fear of demons known as yoma. These vicious creatures can take the appearance and memories of humans they have devoured, thus blending into society as they freely feast on human flesh. The key to stopping the yoma lies with the tolerated yet feared Claymores - women who are half-demon, half-human, and fully fated to become the demons that they hunt. Meanwhile, in a village, the young Raki has been banished; his only crime was losing his family to the yoma. Raki is drawn to a Claymore named Clare, and together their journey begins. While Clare fights the yoma plaguing the land, can Raki help her in her struggle to retain her humanity?
Claymore, like 3x3 Eyes, is another anime that has a lot of monsters and gore. Furthermore, the main characters are very similar as well in that both have multiple personalities and a loyal friend who tries to protect them.
Both of these anime center around a woman with strong powers that she only uses if she's in trouble. By her side is a young male chracter who tries to protect her because she saved his life. With some epic monster battles and a splash of blood, these animes are quite similar.
Much to the annoyance of Kei, he and his childhood friend Katou have died, having been torn apart by a train. But rather than finding themselves at the gates of heaven, the duo materialize in a room full of strangers and a giant black sphere known as GANTZ. As if dying once wasn’t bad enough, the occupants of the room are then forced to embark on dangerous missions to kill strange aliens; missions that very few return from. Now, Kei, Katou, and a well-endowed friend must fight for their freedom with an arsenal of guns, high powered suits, and a very low chance of survival.
Both Gantz and 3x3 Eyes have the characters fighting supernatural monsters. During those fights it's not uncommon to see gore being set as the main theme - and almost the only theme.
In present day England, a war is being fought. The average citizen does not notice, but vampires are running rampant among the populace, and it's up to the Hellsing organization to contain the bloodsucker threat, using even their own weapons against them. Alucard, a vampire himself, is the best agent the organization has to offer, answering only to Integra Hellsing herself. No one knows much about this mysterious figure fighting against the occult, but things starts to change after he “recruits” a new agent to the establishment...
In both Hellsing and 3x3 Eyes the 2nd main character is killed and brought back to life by his/her new masters. From there he/she must figure out themselves and how to fight with this new power he/she has been given. Both have great storylines, and lots of action and blood.
