On September 10th at Korakuen Hall, Koguma challenged Dark Silueta for the CMLL Japan Women's Championship.

Hazuki: "Hazuki is a two-time champion for the first time in her pro-wrestling career! Thank you, Koguma, for fighting me for this CMLL (Japan Women's) belt. If Koguma and I weren't contemporaries, if Koguma hadn't fought in the same ring as me, I wouldn't have become this strong. I think I am where I am today because of Koguma. Thank you so much."
Koguma: "Hazuki, congratulations. You know, we don't have many singles matches, and normally we're a tag team, and everyone thinks we're a strong and close tag team in FWC... No, no, it's not that we don't get along, we usually work together as a tag team, but deep down, we were first classmates and rivals (tears)."
Hazuki: "Don't cry."
Koguma: "We were rivals in the same generation, right? ...But I became a two-time champion more than 10 years ago. We've always been rivals. We're rivals, and we're a great tag team, so just because we lost today doesn't mean one of us is better or worse. We'll continue to compete against each other and become the strongest tag team. And we'll aim for the top. Please support us."
"I've become a double champion for the first time in my pro wrestling career. And what's more, neither of these belts are from Stardom, but from America (Spark Women's) and Mexico. From now on, I want to move around the world. Koguma said it in the ring, but Koguma is my biggest rival, now and always will be. Koguma used to say that I'm a genius, and that Hazuki can't do it no matter how many times she tries. She'd say things like, 'Think faster!' She said a lot of things like that, and I felt like there was a huge gap between us, and I thought it must be great to be a genius. I still think that sometimes, but I got these belts in my own way, through hard work. I want to stand tall and proud in the Stardom ring, and in Mexico where I'm going next, and around the world. Koguma said about 10 years ago that she was the first to become a double champion, but now I'm the double champion. Koguma, let's continue to be rivals and best friends."
"CMLL (Japan Women's) before Mexico. I really wanted to take the belt to Mexico and have a rematch with Silueta. Well, as I said in the ring, I think we have a strong image as a tag team team as FWC. But at first we were 15 years old, from Fukuoka, and each other were my biggest rivals. I didn't really pay her much attention at the time, but she was a huge rival. When we faced each other, that rivalry really came out. It was really fun. But I was the first to become a double champion. We'll always be rivals, and I'll always try to beat her."
