She will use a keyblade when she remembers how. When she teams up with Roxas on a recone mission for a heartless.
The coats Axel, Xion, and Roxas wear are special trenchcoats. If you read Kingdom Hearts II manga. Axel tells Namine' the coat protects them from the black fire. They summon to get from the castle to mission areas in visversa.
As the cover shows she does become friends with Axel, and Roxas. The blue ice-cream they eat is called sea-salt ice-cream. Its ice-cream usually sold near oceans made of ice, vinilla, and sea-salt which is very tasty. Its very sweet, and salty a good food for a mysterious town.
