Rei is kind, patient, and deeply loving, struggling with guilt and trauma, carrying deep regret for harming her youngest son Shoto and losing her oldest, Tōya. She's emotionally fragile yet resilient, slowly rebuilding her life and mending her bond with her children. Her quiet strength allows her to endure suffering, but her past left her hesitant and withdrawn, seeking healing, prioritizing her children’s well-being over reconciliation with Enji while carrying the scars of their painful past.
