Prior to winning the WBO title, back in March, had held the WBA female Super Flyweight title. She had held that title from 2009 to 2012, losing it to compatriot Naoko Yamaguchi. After a number of failed title challenges she seemed like a spent force but would roll back the clock to stop Minowa in 8 rounds to claim her second world title. That win saw Tsunami end a 4 fight losing run in world title fights, including the loss to Yamaguchi.
Abaniel on the other hand has been a regular challenger on the world level, but is yet to claim her first world title. The Filipino has come up short in bouts for the WBA, WBO and IBF female Minimumweight titles, as well as the WBA Atomweight title. Despite those losses she has proven herself a competitive fighter at that level and will know that this is another chance to prove herself.
At the moment no details in regards to supporting bouts have been announced, though we are expecting those details in the coming weeks.
