However, Shiki holds a huge secret. Ever since that injury, he has been seeing lines on objects, and only with a special pair of glasses is he able to stop seeing them.

Tsukihime's follows the perspective of Shiki Tohno who suffered a life-threatening injury when he was young. When he regained consciousness, Shiki was able to see "death lines"[n 1] though his Mystic Eyes of Death Perception (直死の魔眼, Chokushi no Magan?) which causes him immense headaches as his mind cannot cope with the sight of death. Soon after he is given a pair of glasses that blocks the sight of these lines. The game then advances to Shiki's second year of high school. After his injury, he was banished to a branch family of the Tohno household. After eight years he is called back home by his younger sister, Akiha Tohno, when she assumed the responsibility as the family's head. After moving back Shiki has trouble adjusting to the old-fashion lifestyle his sister lives by.

As the story progresses the plot diverges depending upon the choices the character makes. Shiki must use his powers to confront supernatural beings such as vampires (known as True Ancestors (真祖, Shinso?) and Dead Apostles (死徒, Shito?)).

Shiki Tohno (遠野志貴, Tōno Shiki?)
The protagonist of the series. He has Mystic Eyes of Death Perception, which allow him to see the death of things in the form of "lines" and "points" on objects and people; cutting the lines destroys the portion cut, while piercing the point destroys the existence of the object itself. He carries a pocketknife named Nanatsu-yoru (later learned that it can also be pronounced "Nanaya") and is quite skilled in its use. He has been living with the Arima family, one of the branching families of Tohno, since an accident 8 years ago. At the beginning of the anime, he moves back home with his sister, Akiha.

Arcueid Brunestud (アルクェイド・ブリュンスタッド, Arukueido Buryunsutaddo?)
A beautiful blonde with ruby red eyes, Arcueid (or just "Arc" sometimes) is a mysterious vampire princess. But since she is a True Ancestor, she lacks some vampiric qualities, such as that of needing to consume blood to survive, and being nocturnal. She seems to be quite knowledgeable about many things, but is very naive when it comes to modern ideas. She is killed by Shiki in the first chapter, but she doesn't actually die (because she's a vampire) and, in turn, recruits Shiki to help her fight Roa. Arcueid was originally created as nothing more than a weapon to eliminate the True Ancestors that had fallen to their vampiric impulses. She was taught nothing except what was necessary to eliminate her target, and when she returned to the Millennium Castle even that knowledge would be erased before she was put to sleep. Originally did not have the vampiric impulses that all True Ancestors had, but this changed when Roa tricked her into drinking blood hidden within a rose, as she did not know she was not supposed to do that. After that, Roa, turning into a Dead Apostle, used his power gained by having his blood drunk by the strongest True Ancestor and wiped out most of the True Ancestors. From then on Arcueid uses a large portion of her power to suppress her vampiric impulses. She also changed her goal from killing fallen True Ancestors to killing Roa every time he reincarnates. By the time of Tsukihime, due to the weak state that Shiki left her in by "killing" her, she is only at 30% of her full power as she must use the remaining 70% to suppress her vampiric impulses. She is one of the two True Ancestors capable of using the Marble Phantasm, which allows the user to re-create the effect of anything that is naturally possible, (not counting the creation of living beings) and summon the Millennium Castle Brunestud, the home of the True Ancestors. (note: most of these are mainly info from the game, which give some info before the anime episodes, which not clearly explaine didn't the anime... so, basically i didn't let out any spoilers. ^.^)
