The triumph of good over evil was shining though the South Stand when Darth Vader, aka Dave Hughes, stood with his mates from the Rwanda rugby team, dressed as storm troopers.
Star Wars attire was appropriate because Hughes was 'the Force' who brought Rwandan rugby to Hong Kong for the Sevens.
'I read a book about Rwanda's genocide in 2008,' says Hughes. 'And I decided to go there and do something. I partnered with an American woman, Elizabeth Davis, to set up the Akilah Institute to offer women of ages 18 to 30 diplomas in entrepreneurship and hospitality management.'
Not only did Akilah's numbers grow to 160 students, the working partnership between the two grew into love, and the pair is getting married later this year.
Also, a genuine love for Rwanda was forged, and that is what led to the nation's team coming to the Sevens.
'I was cruising through Rwanda one day and I saw some people playing rugby with a Shanghai Hairy Crabs rugby ball,' says Hughes. 'It made me curious, so I contacted the team in Shanghai when I got back to Hong Kong and found that they had donated some kit.'
