Overview
She is Yuzuko's younger sister and was truly happy for her sister and Kazuki's marriage. She plans to go to France to study fashion.

Appearance
While Karin looks very similar to her sister, which Kazuki briefly mistakes her for his wife upon meeting her again, she has shorter and darker brown hair, blue eyes instead of green, and a beauty mark under her lips.

Background
Tired of Kazuki keeps sending her money but avoiding her, Karin goes to Yadorigi to ask about his whereabouts and catches up to him after he left the casino. She tries to convince Kazuki that her sister's death wasn't his fault but he persists and leaves. Later on, Karin meets with Kazuki again after they both visit Yuzuko's grave. This time, they manage to talk properly and she reminds Kazuki that the memories of her sister wasn't supposed to be a prison and that he should move on and live his life, which she believes would make her sister happy. After Kazuki says he would try at it a bit harder, she smiles and is genuinely happy for him.
