Description
Ren Sohma served as a maid in the Sohma household before becoming the widow of former family head Akira Sohma and mother to Akito Sohma. She initially gained Akira's attention by seeming to alleviate his loneliness, leading to their marriage despite senior staff objections.

During her pregnancy, zodiac members' dreams revealed her child as the reincarnated "God." Learning the baby was female, Ren threatened abortion unless the child was raised male, fearing Akito would supplant her in Akira's affection. After Akito's birth, Ren resented the attention her daughter received, refusing to hold her. She subjected Akito to persistent verbal and emotional abuse, dismissing the zodiac bonds as delusional fantasies and declaring Akito's existence unnecessary.

Akira's death saw Ren excluded from his deathbed while Akito remained present. This exclusion ignited Ren's rage. She proclaimed Akito had been merely a temporary distraction for Akira and that no one needed her anymore, significantly contributing to Akito's development of controlling and abusive behaviors toward the zodiac.

Ren maintained a longstanding antagonism toward Akito, culminating in a bet: Akito would allow zodiac members outside relationships to prove their bonds unbreakable. If any member chose not to return, Akito would kneel before Ren and exile herself from the family.

Ren manipulated others to inflict pain on Akito. She informed Shigure Sohma of Akito's affair with Kureno, then seduced Shigure—partly to spite Akito and partly due to his resemblance to Akira—resulting in Shigure's banishment. She deceived Isuzu "Rin" Sohma, falsely claiming Rin's parents were happy despite their resentment. When Rin confronted them, their subsequent abuse caused Rin severe trauma. Later, Ren manipulated Rin into stealing a box she believed contained Akira's soul, leading to Rin's imprisonment and near-fatal punishment by Akito.

Following Akito's transformation into a more responsible head and reconciliation with the zodiac, Ren's mental state deteriorated further. She rejected Akito's reconciliation attempts and directed her hatred toward her grandson, Shiki Sohma, due to his resemblance to Akito. Ren attempted to stab Shiki, but Akito intervened and sustained the injury. After this attack, Ren was likely institutionalized for psychiatric care.

Ren's actions originated from an obsessive fixation on Akira and profound jealousy of Akito's status as the zodiac's "God." Her manipulation and abuse directly shaped Akito into an abusive figure and inflicted lasting trauma on multiple zodiac members.
