A Japanese MMA promotion recently caused outrage by pitting a 12-year-old girl against a fighter twice her age.
Video has now emerged of the brutal bout.
12-year-old Momo Shimizu dominated her MMA debut against her 24-year-old opponent.
In a fight that divided the MMA community, Momo easily won via a first round rear-naked choke at Deep Jewels 16.
After taking some early blows to her head from her bigger opponent, the 150cm pocket rocket took her opponent's back and demonstrated her superior skill to finish the fight with the submission.
The controversial fight caused a huge stir when it was first announced, that the seventh-grade student would compete in her first MMA bout against 24-year-old Momoko Yamazaki.
Yahoo Sports combat expert Kevin Iole has since described the stunt as bordering on child abuse.
"It is repugnant that this farce was permitted," he said.
"The fact that the pre-teen was victorious is beside the point.
"No 12-year-old is equipped, either physically or emotionally, to be competing against adults.
"Their bodies — and minds — are still developing and the risks are far too great to allow this to occur.
"That someone thought this would be a good idea is a study in poor judgment. Children this age and younger who compete need to do so in a structured, controlled environment against opponents of similar age, size and skill level.
"It borders on child abuse that this was permitted."
It's not the first time a Japanese MMA promotion has exhibited horribly unfair match ups.
Last year, Brazilian monster Gabi Garcia ruthlessly beat up 49-year-old Japanese former pro-wrestler Yumiko Hotta during a crazy fight for Rizin Fight Federation.
