If one looks closely in some of the " Dirge of Cerberus - Final Fantasy VII - " cutscenes , one can spot Lucrecia wearing a pair of silver earrings in an ornate filigree design that somewhat resembles the shape of a dagger , similar to those of musician Gackt who contributed " Longing " and " Redemption ' to the soundtrack and served as a model for Genesis Rhapsodos . Personality . Lucrecia suffers from a guilt complex . She has a kind and caring soul but tends to ignore the realities of life and convince herself to believe only what she wants to believe . Being a scientist , she is prepared to take risks for her research , something she , albeit to a lesser extent , shares with her colleague Professor Hojo . She can be emotionally volatile and stubborn . Story . Lucrecia , once a Class A Biotechnologist for the Shinra company , worked as an assistant to Vincent ' s father , Grimoire Valentine . They discovered two Weapons developed by the Planet used as part of the Lifestream ' s emergency function . Together , Grimoire and Lucrecia discovered the cave where it was thought Chaos would awaken at the appointed time . The newly - discovered Chaos killed Grimoire and Lucrecia ' s research was discarded as nonsense . Lucrecia was appointed to work on the Jenova Project along with Gast Faremis and Professor Hojo . Vincent Valentine , a member of the Department of Administrative Research ( which would later be known as the Turks ) was assigned to protect the scientists . Lucrecia recognized Vincent as Grimoire ' s son and was shocked Shinra would assign the son of her deceased mentor as her bodyguard . As time wore on she began spending time with him when the two were off work , although she concealed having known his father , and the two grew close . When Vincent spotted a document left on Lucrecia ' s work monitor telling of her time working with Grimoire , he confronted her and she revealed her culpability for his death . Vincent — not seeming to think Lucrecia was responsible as much as she did — attempted to console her , but Lucrecia was overcome by guilt and sought Hojo for comfort . Lucrecia married Hojo and became pregnant . They agreed to use their unborn child as a test subject for the Jenova Project by implanting him with Jenova cells in the embryonic stage . This had an unexpected side effect : Lucrecia was frequently in pain and experienced visions of her son and the future atrocities he would commit . When Vincent confronted Hojo about what was going on , Hojo shot him and experimented upon his corpse , but soon labeled this side experiment a failure and discarded him . Lucrecia , devastated by Vincent ' s death , used her knowledge about Chaos to resurrect him by introducing Chaos energy to his body . Vincent ' s body was strong enough to become a Chaos vessel due to what Hojo ' s experiments had already done to him , but Chaos was out of control and only stopped when the Protomateria reacted to it . The Protomateria , which she and Grimoire had discovered and which Lucrecia theorized to have been created by the Planet " out of necessity as a means to control Chaos and prolong its own inevitable fate , " had been in Lucrecia ' s laboratory presumably since Grimoire ' s death . She put it inside Vincent ' s chest and thus Vincent was able to control Chaos to a degree , but while it halted Vincent ' s decay , it did not immediately resuscitate him . Lucrecia gave birth to Sephiroth , although it is unclear whether his birth occurred before or after Vincent ' s death . Sephiroth was taken away without Lucrecia even being allowed to hold him . While dealing with the emotional turmoil surrounding the loss of her infant son and the death of Vincent , Lucrecia was overcome with self - loathing and sorrow . She gave up on attempting to save Vincent and attempted to kill herself , but not before leaving her thesis about Chaos and Omega for the still unconscious Vincent . Due to the Jenova cells in her body , Lucrecia was unable to die and fled , ending up in the Crystal Cave where she and Grimoire had discovered Chaos . Many years later , when the Planet is faced with destruction at the hands of her son , Lucrecia is found by Vincent while he is traveling with Cloud ' s party . When Vincent attempts to approach her , Lucrecia tells him to stay back . Vincent flashes back to his time spent with Lucrecia on the Jenova Project , and Lucrecia explains she felt such guilt she wanted to disappear or die . Lucrecia has been dreaming about Sephiroth and asks if her son is still alive , as she has heard about his supposed death but doubts the verity of the news . Vincent , who does not have the heart to tell her of the horrible things Sephiroth has done and is planning to do , tells Lucrecia that Sephiroth is dead . Lucrecia remains in the cave and becomes encased in crystallized fountain of natural Materia that was there when she and Grimoire first discovered the cave . Vincent has several visions of her attempting to communicate with him through the crystal concerning Chaos , but the only words he is clearly able to make out are " I ' m so sorry . " These were the last words she spoke to Vincent before running from him and starting a relationship with Hojo . Following Omega ' s destruction , Vincent returns to the Crystal Cave and informs Lucrecia that Chaos and Omega have returned to the Planet . He tells her that " everything is all right now , " thanks her , and tells her she is the reason he survived . As Vincent departs , a tear rolls down Lucrecia ' s cheek . It is stated in the " Dirge of Cerberus - Final Fantasy VII - Official Complete Guide " by Scenario Coordinator Hiroki Chiba and Producer Yoshinori Kitase that Lucrecia is still alive , that the crystal she resides in is a product of Lucrecia herself , and that her imprisonment within it is self - imposed . Gameplay . Lucrecia is briefly mentioned in a sidequest in " Final Fantasy VII " where the player can recruit the optional character Vincent to the party . The player can later find Lucrecia at her cave behind a waterfall near Nibelheim after Cloud returns to the party following the Mideel events . To meet Lucrecia , Vincent must be present in the active party . Following the event scenes the player must leave the cave and fight at least ten random encounters . Returning with Vincent his Limit Break manual and his ultimate weapon , Chaos and Death Penalty respectively , can be found at the back of the cave . Creation and development . Lucrecia was designed by Tetsuya Nomura and initially had a minor role in the backstory of Vincent , an optional character in " Final Fantasy VII " . Her role was expanded upon when Vincent became the main protagonist of " Dirge of Cerberus - Final Fantasy VII - " . Her character model was redesigned to more strongly resemble Sephiroth ' s appearance , and her backstory was expanded upon to connect her with Vincent ' s father and with Chaos , a form Vincent can assume as a Limit Break after he encounters her in " Final Fantasy VII " . Though Vincent states in " Final Fantasy VII " that Lucrecia was the person whom he " loved and respected most , " it was unknown whether or not Lucrecia returned his feelings . In " Dirge of Cerberus - Final Fantasy VII - " , such a reciprocation is implied when her thoughts flash across the screen late in the game containing , among other sentence fragments , " Vincent . . . " and " I loved . . . " The Early Material Files included with the " Final Fantasy VII Ultimania Omega " guide ( scenes and ideas cut or changed in the final game ) , paint a different picture of the dynamics between Lucrecia , Vincent , and Hojo in the early character designs . Vincent ' s section mentions Lucrecia was originally " on Vincent ' s side , " drugged by Hojo , and forced into experimentation against her will . ( In the game ' s final version , and " Compilation " canon , she was a willing albeit conflicted participant . ) The Early Material Files also mention she was considered an " idol " in the lab , and was the only woman on Hojo ' s team . " Dirge of Cerberus - Final Fantasy VII - " contains some concept artwork for the picnic basket she carries to Vincent in a flashback , and the concept artwork shows it has a bottle of red wine . The opening FMV sequence shows a wine glass in Vincent ' s room containing a red liquid some decades later . Voice . Lucrecia shares her Japanese voice actress , Rio Natsuki , with Lulu from " Final Fantasy X " and " Final Fantasy X - 2 " . She shares her English voice actress , April Stewart , with Mjrn from " Final Fantasy XII " . Etymology . This may have been meant to hint to the nature of Lucrecia ' s forced participation in the Jenova Project in early game designs ( when she was named ) , or it could be meant to emphasize the perverse nature of Sephiroth ' s conception . The katakana for Lucrecia ' s name is read as " Rukuretsia " , suggesting her name may have been intended to be either or .
