Sylphie appears as a weapons dealer who is responsible for selling armors and other items to the anonymous space marines in exchange for Zenny and hinting them how to defeat the end bosses of the respective stages in the game. Her shop can be located in each stage. If one of the duo got in, then he has a limited amount of time to buy important goods for achieving the heroic goals against Bios and its evil army.
Namco X Capcom
In this crossover entry, along with the two anonymous soldiers, Sylphie serves her 2 roles: shopkeeper and ally. She joined forces with Reiji, Xianmu and the heroic allies of both Namco and Capcom dimensions to fight evil while taking the time to do their job in her shrewd way though. In combat, she has a tactical set of moves lifted from Capcom video games like Pirate Ship Higemaru and Alien vs. Predator, the arcade-exclusive title.
- Actually, Sylphie bows to the audience when her item shop is entered in the Japanese version of the game and greets the Unknown Soldiers with vocals. But in international version, she is being silent and doesn't move.
