Continuing on with a stream of retirements, Jewels poster girl Mika Nagano will be retiring at Deep Jewels 3. She will be taking part in an exhibition match followed by a retirement ceremony. This comes as a big loss to Deep Jewels and WMMA in Japan. Nagano was one of the promotions bigger draws and did quite a bit of promotional work. The fighter who was originally know for her wrestling and armbar finishes, has shown evolution in her recent fights. Her striking and ground and pound looked much improved recently. It is yet to be known why she is retiring and if she will continue with her pro wrestling.
