Lunar Legend Chronicles Series by Sasaki Shōnen

A childhood accident has left young Shiki Tohno with a very special ability. He can now see the hidden lines or weak points in all things - be they organic or inanimate. By striking or cutting along these lines Shiki can slice through virtually anything like a hot knife through butter.

Though a young girl falls victim to Shiki's killing lust, she is apparently reborn unharmed and demanding Shiki's aid. Who is she, and what could she want? less

Shiki has destroyed Nero Chaos, but the vampire victims seem to be increasing in the city. Is this Arceuid's doing or is there another vampire around? We all know Arceuid is a blond bombshell vampire, but who is Shiki's high school idol Ciel and his sister Akiha? Find out their true identity as they all scramble over Shiki.

After a furious bout that displayed Akiha's powerful pyrokinetic ability, Ciel is convinced Akiha is not the vampire she was seeking. Meanwhile, Shiki begins to dream of bloody nightly rampages and wonders if he is Roa. His nightmare soon becomes reality when he encounters a strange man who attacks him with a knife aiming at his thread of life!

After rescuing Shiki from his dangerous encounter with Roa, Ciel warns him in vain to stay away from Arcueid, who may have an ulterior motive. Meanwhile, Shiki cannot shake off the feeling that he knows Roa, and a visit to the garden of his house jolts his memory, piercing him with visions of Roa as a child, along with a voice telling him that he will become a "true monster" someday.

The violent, bloody action continues when Shiki loses control of his senses and reveals his true "monster" nature within him as he goes on a mad killing spree! Subsequently, Shiki begins to recall fragments of his childhood memories, which reveal some important secrets of the Tohno family.
