"I was also a member of the Task Force. I was even giving them suggestions and supporting them in ensuring a clean competition. But what have they done with me?" she said.
The 38-year-old, multiple-time Asian champions who was eyeing her second Olympic medal after the bronze at the 2012 London Games, said this evening's loss did not sink in even after she had gone for her dope test.
"I was happy inside the ring, when I came out, I was happy because in my mind I knew I had won. When they took me for doping, I was still happy. Only when I saw the social media and my coach (Chhote Lal Yadav repeated it to me), it sunk in that I have lost," she said.
"I had beaten this girl twice in the past. I couldn't believe that her hand was raised by the referee. I swear, it hadn't struck me that I lost, I was so sure," she added.
The Indian trailed 4-1 in the opening round with four of the five judges scoring it 10-9 in favour of Valencia. In the next two rounds, Mary Kom got three of the five judges to rule in her favour but the overall score-line was still in favour of Valencia.
The Manipuri needed a 4-1 verdict in the final round to swing the bout for her.
"The worst part is that there is no review or protest. Honestly I am sure the world must have seen, this is too much what they have done," she said.
"I should have got the second round unanimously, how was it 3-2? What happened was totally unpredictable," she reasoned.
The IOC's Boxing Task Force had promised a more transparent judging system after amateur boxing's credibility took a hit during the 2016 Rio Olympics judging fiasco which led to suspension of 36 officials.
Mary Kom is part of the BTF's 10-member athletes ambassadors group.
She represents the Asian bloc in the panel, which also comprises the likes of Ukrainian legend Vasyl Lamachenko (Europe), a two-time Olympic and world gold-medallist who now plies his trade in the professional circuit, and five-time world champion and 2016 Olympic gold-winner Julio Cesar La Cruz (Americas) among others.
"...in a minute or in a second everything gone for an athlete. This is unfortunate what has happened. I am disappointed by the judging," she said.
But the veteran is in no mood to quit despite her Olympic journey coming to an end with the Tokyo edition. At present, boxers above 40 are not eligible to compete at the Games.
"I will take a break after coming back, spend time with family. But I am not quitting. If there is any competition, I will continue and try my luck," she said.
The AIBA is trying to regain IOC recognition by ringing in several changes in the administrative set-up under new President Umar Kremlev, which includes the introduction of the bout review system to ensure that boxers' grievances are addressed.
"You can't do that here. I would have definitely protested otherwise," Mary Kom said.
