When Arihiko was young, the apartment complex he lived in collapsed with him and his family in it. He was the only one on the third floor to survive. His parents died in that disaster. Before he got rescued, he had been stuck in the rubble for three days. When the apartment complex collapsed, he saw his grandmother die before his eyes, which caused him to have a different look on death. He was more-or-less raised by his older sister Ichiko Inui and currently lives with his sister.
When Shiki was living with the Arimas, he often used to hang out with Arihiko. He has a competitive attitude against Shiki. The second Arihiko laid eyes on Shiki, he intuitively knew that he was broken. "I've decided, you're going to be my rival." So he declared, while eating the pudding he had just stolen from Shiki's lunch.
He's a model outlaw and he wore the same style of clothing since elementary school.
He has a tendency to wander. He has the same antisocial attitude since elementary school. He enjoys living a delinquent lifestyle that doesn't bother normal, upright people. Though he's rumored to be something of a womanizer, his exes have nothing but good things to say about him. It seems he's the kind of Don Juan that wants girls to be happy even after he's parted ways with them".
As far as Arihiko know, Ichiko is a mysterious person who changes jobs about once a year.
Arihiko plays an important role in Shiki's school life; that means he primarily appears in the beginning of Tsukihime (providing a lot of exposition) and the school parts of Kagetsu Tohya.
As the player moves through the story, the player will discover that sometimes, Shiki cannot grasp how he became friends with Arihiko in the first place, since Shiki believes Arihiko has a "weird personality." Yet at one point in the game, when Shiki collapses in class due to his condition, Arihiko is the one who loudly informs the teacher that Shiki is sick and needs to be excused. Arihiko then proceeds to help a physically-weakened Shiki to the medical office, thus demonstrating a personality trait that might, depending on the player's subjective perception, serve to explain why Shiki continues to be friends with Arihiko despite Arihiko's sometimes callous behavior. Furthermore, because his grandmother died in front of him saving his life as a child, he does not see react to death the way normal humans do, allowing him to coexist more easily alongside Shiki.
He does not, however, appear in any of the endings of Tsukihime, and Hisui's and Kohaku's route barely feature him at all.
Background information on him is introduced in the Kagetsu Tohya side story "S.O.S. Nanako-chan". In that story, he stumbles upon and eventually befriends the Seventh Holy Scripture's spirit, and gives her the name "Nanako".
Arihiko makes a brief cameo appearance in Carnival Phantasm.

 Tsukihime Dokuhon PlusPeriod - TSUKIHIME Dictionary: Inui Arihiko [Person's name], p.176
Arihiko Inui [Person's name]
Shiki's partner in crime. He has a tendency to wander. He's been hanging out with Shiki since elementary school, and had the same antisocial attitude and style of dress even then. His parents died in a disaster when he was young, and he was more-or-less raised by his older sister. He's a model outlaw (huh?), and enjoys living a delinquent lifestyle that doesn't bother normal, upright people. In contrast to Shiki, who became an outcast for the sake of those around him, Arihiko did it for himself.
Though he's rumored to be something of a womanizer, his exes have nothing but good things to say about him. It seems he's the kind of Don Juan that wants girls to be happy even after he's parted ways with them.
At first glance, it doesn't seem like he would have very good compatibility with Shiki at all. The tale of how these two destined lovers met is told in Kagetsu Tohya.
The second Arihiko laid eyes on Shiki, he intuitively knew that he was broken. "I've decided, you're going to be my rival." So he declared, while eating the pudding he had just stolen from Shiki's lunch.
In the side story "Nanako-chan S.O.S.", his fate was intertwined with the delinquent elemental Nanako, but normally he hates stuff like ghosts and monsters.
 Tsukihime Dokuhon PlusPeriod - TSUKIHIME Dictionary: Inui Ichiko [Person's name], p.176
Ichiko Inui [Person's name]
Arihiko's older sister. Her nickname is Miss Strawberry.
Because Shiki has been hanging out at the Inui house since he was a middle school student, Ichiko could also be considered an acquaintance of his. Or perhaps it would be better to call her an existence he can't defy.
Though her way of life is even more self-indulgent than Arihiko's, she is a splendidly independent adult woman.
As far as Shiki and Arihiko know, she's a mysterious person who changes jobs about once a year.
Sometimes if something good happens she'll give Shiki a present to commemorate it, but invariably it's always something completely inscrutable. Still, since it seems to mean a lot to Ichiko, Shiki values them greatly.
 Tsukihime Dokuhon PlusPeriod - TSUKIHIME Dictionary: Nanako [Weapon name • Name], p.186
Nanako [Weapon name • Name]
The elemental residing in the Seventh Holy Scripture.
Although Ciel calls her Seven, she was named Nanako by her temporary master of just a few days, Arihiko.
A young girl with a mysterious character. It's hard to say if she's noble or nasty. She can't help but lament the tyrannical treatment she receives from Ciel, but if she ever fired back she'd just get in trouble. Basically, she's a character at the very bottom of society. Originally she was the girl offered up as a sacrifice during the creation of the Seventh Holy Scripture, but after her death she merged with the holy beast used as the scripture's foundation and ended up with her current form. Her most distinctive characteristics are her blue, sci-fi bodysuit and her hoof-ish hands and feet.
Though she is the guardian spirit of the Seventh Holy Scripture, that doesn't mean that she's the guardian spirit of the Seventh Holy Scripture's wielder as well. The reason that she complies with Ciel's orders regardless is because Ciel is the first master she's had capable of giving her form. Manifesting a guardian spirit isn't something that can be accomplished without an excessive amount of magical energy, after all.
She's always grumbling about Ciel's violent treatment (of the Seventh Holy Scripture), but nevertheless she sticks to her like glue. In Melty Blood, she appears briefly during Ciel's stage entrance and Arc Drive.
By the way, in the third character popularity poll Nanako's Arc Drive was listed as "Holy Cross Burial Scripture", but it should be read as "anti-reincarnation".
