Kahara Tomomi’s her stage name, which he had her use to have the same initials as him.
And actually she released music on ORUMOK Records, which is Komuro backwards... Their relationship was completely woven into her Cinderella story, and I think at one time he may have liked her, but I don’t think it was as ever as deep as she thought, and their breakup led her down a really bad spiral. As he already got her into drugs, she fell into that more, and missed performances and recordings, and eventually her labels dropped her and she went to rehab. She’s better now, and doing well.
But basically, she was his protege... until she wasn’t.
I’ve heard terrible rumors about them though. Where he’d get her high and parade her around in her disheveled state.
