For other students at View Park High, a charter school situated in gritty urban South Los Angeles, playing rugby represents a possible route to college, further education or an opportunity for travel.

Toliver, a prodigiously gifted athlete who was named in the first All-American girls' high school team earlier this year, says the physical nature of rugby has given her an outlet other sports cannot provide.

"I used to play basketball but I always used to get fouled out because I was so aggressive. So rugby's the perfect sport for me," Toliver says with a smile.

Toliver was drawn to the rugby programme after seeing the experience of her elder sister, who took part in a school tour to South Africa, one of several overseas trips the school has organised.

"When she came back from that trip to South Africa, she had a totally different outlook on life. And that made a big impression on me."

Desiree Smith, 17, meanwhile says she hopes rugby can help her land a place at college.

"I want to study to be a history teacher and a rugby coach," she said.

Like Toliver, Smith says she was drawn to rugby's innate physicality.

"It's another way to get anger out," she says. "I get frustrated a lot."

Part of the Inner City Education Foundation, the rugby programme began in 2003 under the direction of former Hong Kong international Stuart Krohn who was a member of Hong Kong's famed Plate-winning side at the 1992 Sevens.

Krohn says the programme's purpose is to broaden the horizons of students, who are predominantly African-American. "Rugby's a vehicle to open people's ideas to something new, something different," he says.

Krohn says while the rugby programme has tangible value in helping direct students towards college, the sport's core values – camaraderie, teamwork, respect for opponents – are helping build confidence and character.

"We're a character-based programme," Krohn says, citing the example of high school teen Smith.

"When I first met Desiree, I didn't think she was going to make it," he says.

"She was like a wounded bird, always looking for a way out. And I thought to myself, 'She'll quit'. But she never did. Man, she just kept coming back and coming back. Now? She's strong. She's one of our main players."

Smith, meanwhile, talks in awe as she recalls her participation in the team's tour of Japan in March.

"Japan was amazing, so clean and peaceful," she says. "I didn't see any angry people there."

Yet Smith says her best rugby memory came not during her trip to Asia, but when she suffered an ankle injury soon after taking up the sport.

"My first year I got hurt and all the boys and girls joined together to help carry me off the field," she said. 

"Never seen anything like that before."

Olympic hopeful Toliver, meanwhile, will likely be supporting Fiji when the South Pacific islanders open the World Cup against England at Twickenham on Friday.

"We don't have cable TV but my dad and I watch the games on a rugby website," Toliver says. 

"The first time I saw proper rugby live was at the Hong Kong Sevens [in 2013] – Fiji are awesome."
