Osman, who was named a TIME magazine Next Generation leader in 2014, will be back in action in March when she fights at Stadium Putra in Kuala Lumpur.
Osman revealed she is descended from a tribe of head-hunters, saying: "I inherited that fighting spirt. I have a really strong part in fighting, just not giving up and keep on going.
"My day-to-day routine is to get up really early, train, work, get back to training, work and end the day with a few more hours of training. I have two different roles, a corporate career and as a fighter, but I try to manage that by balancing my time and making sacrifices where needed."
She added: "I earned my nickname Athena from my coach. I like it knowing it means goddess of war. I'm happy and proud to be representing Malaysia… MMA is it has really empowered me as a woman, you feel like you've just conquered the world, you feel like a winner.
"All I think about is train hard, fight hard and bring home the win."
