Bring the water and rice to a boil in a medium saucepan. Cover, reduce the heat and simmer 15 minutes or until water is almost absorbed. Remove from heat and let stand, covered, for 15 minutes.
Place the rice in a large bowl. Add the sugar and coconut milk, stirring gently until well combined. Cover and let stand 20 minutes.
Divide the rice mixture in half. Using a sushi mat turn half into rolls, using fruit roll ups in place of sushi nori, and fill with kiwi and mango pieces and a sprinkling of sesame seeds.
Use the other half for nigiri, topping with slices of fruit and lime zest.
