"My mum came into my room and she started crying. My little sister is only 14, she normally goes to all these concerts and we were so lucky she never went to that one.
"We were thinking, if that was my little sister, we wouldn't know what to do. It was so devastating to see - there are no words for what those people are going through.
"It was tragic what happened. It was a devastating thing and my heart goes out to all the families out there.
"I'm going to put a show on for the fans and for Manchester, and I'm going to dedicate this fight to Manchester. Believe me, I will be winning it."
Fury had no reservations about being involved in one of the first events the arena will host upon its reopening and has been heartened by the community spirit his fellow Mancunians have shown following the attack.
"It's showing people aren't scared," he added. "It was an amazing feeling to see so many people come out in Manchester after that happened.
"They filled the streets, and it was incredible that so many people stuck together and were so strong.
"They've shown you can't run scared, you've got to show these people. They did and I'm proud of Manchester for that."
This will be Fury's 21st professional bout, his first in well over a year, due to illness and injury, and his maiden shot at a world championship belt against a fellow undefeated boxer.
He is also the underdog against Las Vegas-based Parker, whose team have angered their next opponent by using their time in England to meet Anthony Joshua and Tony Bellew's promoter Eddie Hearn.
"I can see their team and him are looking past me already, underestimating me," Fury added at a press conference, which he attended with cousin Tyson, a former heavyweight world champion himself.
"They're already going on meetings with Eddie Hearn and arranging fights. I would take me completely seriously, because I am coming for that belt 100 percent.
"And to Eddie Hearn, cockroach, because that's what you are, you and your big stiff fighter [Joshua], I'm coming for you next. When I get that belt, me and Tyson are unifying this full division together."
Fury's outburst provoked quick reassurances from Duco director David Higgins, who said his Auckland-born fighter's attention was completely focused on his next opponent.
They had come too far - all the way from New Zealand - to throw away a chance to make contingency plans with a boxing powerbroker like Hearn.
"A promoter's job is to scan ahead," Higgins said. "The boxer and trainer are fully focused on the fight in front of them.
"It's a great fight - Hughie, world amateur champion, unbeaten, with Peter Fury in the corner, a good tactical corner there. Joseph, lightning-quick hand speed, never been knocked down in sparring or fights."
This bout had originally been scheduled to take place in New Zealand in May, only for injury to rule Fury out.
Staging it in the challenger's backyard may now be more favourable to him, but Parker, 25, was determined to enhance his reputation in a country Joshua has helped make the epicentre of the heavyweight division.
"There are exciting fights happening here," Parker said.
"Our team felt like we wanted to be a part of it. It was very important for us to come and fight here, and hopefully put on a great performance, so we can show the world what we're made of."
