There's no getting around this.  Ren is an absolutely terrible human being.  She forced Akito to grow up as a man, even threatening to abort her if that didn't happen, all because she wanted to remain the most important woman in her husband's life.

Ren stays on the estate, but she remains locked away so she won't interfere with Sohma matters or hurt Akito anymore.

She appears in one scene at the end when Noa comes to see her to tell her that she is forbidden from ever speaking to Akito again.
