Ginny Weasley

Ginevra Molly "Ginny" Weasley is the youngest of the seven Weasley children and "the first girl to be born into the Weasley clan for several generations."[25] She is introduced in Harry Potter and the Philosopher's Stone, in which she appears when Harry and four of her brothers leave for Hogwarts, and at the conclusion, in which she is excited to catch a glimpse of Harry upon his return.[26]
In Harry Potter and the Chamber of Secrets, Ginny is a first-year Hogwarts student, having been sorted into Gryffindor. While she initially plays a behind-the-scenes role, looking mysteriously ill and having a crush on Harry, it is revealed in the climax that Tom Riddle's diary is possessing Ginny as a means to access the Chamber of Secrets and unleash a basilisk within the school grounds. Riddle's memory residing inside the diary brings her to the Chamber, intending to restore himself to full life by killing her.[27] Harry foils this plot by destroying the basilisk and the diary, thus saving Ginny's life. It is later revealed that Lucius Malfoy was responsible for planting the diary amongst Ginny's school books,[28] in hopes that her actions would discredit her father and lead to Dumbledore's removal from Hogwarts.[29] Ginny has little involvement in Harry Potter and the Prisoner of Azkaban and Harry Potter and the Goblet of Fire.
Ginny has "given up on Harry months ago" in Order of the Phoenix,[30], and it is revealed that she has a boyfriend, Michael Corner, whom she met at the Yule Ball. When Umbridge punishes Harry with a "lifetime" Quidditch ban, Ginny replaces him as Gryffindor Seeker. She joins the D.A. and is one of five members who join Harry during his attempt to rescue Sirius Black from the Department of Mysteries. During the last part of the book, Ginny breaks up with Michael because of his sulking over Ravenclaw losing the Quidditch Cup final to Gryffindor, and starts dating Dean Thomas.
In Half-Blood Prince, after she casts the Bat-Bogey Hex on Zacharias Smith, new Potions professor Horace Slughorn respects her magical abilities enough to invite her to join his "Slug Club". Ginny becomes a Chaser for the Gryffindor Quidditch team, and substitutes for Harry as Seeker when Snape puts him in detention during the Quidditch Cup final. After witnessing Ginny fiercely kissing Dean in a private hallway, Harry eventually accepts the fact that he fancies Ginny, but since Ron vocally objects to Dean dating his sister, Harry interprets this as his not wanting any of his friends to date her. Ginny's relationship with Dean ends altogether in April following an accidental "nudge" from Harry under the effects of Felix Felicis, which Ginny interprets as Dean unnecessarily trying to help her through the portrait hole.[31] Ginny and Harry share their first kiss after Gryffindor again wins the Quidditch Cup over Ravenclaw, thus initiating their relationship. Ginny joins the other D.A. members from the battle of Department of Mysteries to protect Hogwarts from Death Eaters who entered the school, but after Dumbledore's death, Harry decides to end their relationship as he fears his feelings for Ginny would place her in danger; he is surprised at how well Ginny handles his decision.
Propelled by the revelation that Harry, Ron, and Hermione are leaving to seek the remaining Horcruxes in Deathly Hallows, Ginny gives Harry a passionate kiss in her bedroom, which is interrupted after Ron "accidentally" walks in on the moment. She returns to Hogwarts for her sixth year, where she works with Neville and Luna on reuniting Dumbledore's Army, participates in a plot to steal Gryffindor's sword from Snape's office, and is banned from Hogsmeade for an unknown offence. Because Ron is on the run with Harry and Hermione, Ginny is forced to go into hiding with her family, but she returns to school before the Battle of Hogwarts takes place. Though underage, she eagerly takes part in the battle despite her mother's and Harry's disapproval.[32] After Harry's supposed death, she, Hermione, and Luna take on Bellatrix Lestrange, who nearly strikes Ginny with a Killing Curse, causing Mrs. Weasley to step in and slay Bellatrix herself.[33] When the battle ends and Voldemort is defeated, Harry sees Ginny with her mother and decides to not interrupt, thinking that there would be time to talk later.
In the epilogue, set nineteen years after the events of Deathly Hallows, Harry and Ginny are married and have three children: sons James Sirius and Albus Severus, and daughter Lily Luna. Rowling extrapolated on Ginny's future after the release of the book, saying that after leaving Hogwarts, she joined the Holyhead Harpies and, after spending a few years as a celebrated player, retired to become the senior Quidditch correspondent at the Daily Prophet.[34]
Ginny has been played by Bonnie Wright in all of the Harry Potter films to date.
