The much younger foe will be 24 year old Filipino challenger Norj Guro (7-3-1, 4) who will be fighting in her first “Big 4” world title bout and although she is much younger than the champion she is still viewed as the notable under-dog.
Although the champion is 45 she is full of desire and energy that belie her years. As well as her brilliant engine she is also tough and has shared the ring with several notable fighters, including Nanako Kikuchi, Ayaka Miya, Krisztina Belinszky and Momo Koseki, and has a career dating back to 2003. The desire to be a world champion drove her to winning her title and that same desire will see her doing all she can to keep it for as long as possible.
It's hard to say too much about Guro in terms of what she's like as a fighter due to next to no footage of her being available however we can get a read of her from her opposition and her record.
The Filipino started her career 5-0 (4) though all 5 of those bouts came against debutants. Her running came to an end when she faced her first notable opponent, Japan's Riyo Togo, who stopped her in 4 rounds. Since then Guro has gone 3-2-1 with her wins coming against a debutant and a 0-1 fighter whilst her losses have come to the only fighters with more than a single bout of experience.
Going on what we know of the two fighters it's hard to see anything but a clear win for Ikeyama who should retain her title with out too many worries. The only worry we have for Ikeyama is her age and there is a chance she could “get old over-night”. There is a chance of that but it's slim and even if that happens we still suspect she'll know enough trick to over-come Guro.
