Yes Kaname turns her into a vampire and Zero is mad.
They are from the Vampire Knight anime.
ya they are so far in the series
Matsuri Hino (creator of Vampire Knight) stated that Yuuki is "probably age 16".
Yuuki Kuran in "Vampire Knight" stays with her adopted brother Kaname Kuran, who is also her love interest in the series. They were raised together in the Kuran family household after Yuuki lost her memories as a young girl.
Vampire Knight Guilty (Season 2) Episode 7
Artemis is the weapon used by Yuuki Cross. In Yuuki's hands(after she is turned) it transforms into a giant scythe that she uses to cut down enemy vampires.

Zero is in love with the human Yuuki, but when she becomes a vampire he threatens to kill her because she is a pureblood. The manga is still being written but he still more than likely will aways love her.
Yuuki's past in "Vampire Knight" revealed that she was attacked by a vampire as a child and saved by Kaname Kuran. She lost her memories of this event until it was triggered later in the story. This traumatic experience shaped her relationship with vampires and influenced her journey throughout the series.
Yes, but she has always been a vampire it's just that her mother, to protect her, hid her vampire self inside her so she could live life as a human. And it is revealed that Kaname is her brother in the last few minutes of the episode.
SPOILER ALERT! I am not sure, as I read the manga, but Yuuki was a pureblood by birth. Kaname is her brother and fiancee. Her mother gave up her life to seal Yuuki's vampire powers. Purebloods are top of the chain, but there are 'grades in purebloods too (kinda) and yuuki is the best kind/type/etc.
If this about Yuuki and Kaname leaving Cross Academy I believe that is in Volume 10 of Vampire Knight.
