Rena and Little Tiger are both confirmed contestants for this year's Sasuke, Ninja Warrior in the States. Looking at the roster of 100 people it looks like Rena is representing Shoot Boxing and Little Tiger will be representing Muay Thai. I didn't recognize any other women as martial artists on the list. This will be Rena's 2nd time on the course to my knowledge, having actually done pretty well her first time. She just wasn't able to jump from the trampoline to the rope net. I am fairly certain that this is Little Tiger's first time. Sasuke is not only a popular show in Japan, but the world. This is some good exposure for the two.
