Kōsuke Fujishima
Alvin is designed by Kōsuke Fujishima. Fujishima stated Alvin's design was easy to conceive though the color of his scarf was hard to decide on. The writers wanted Alvin's intention to betray the party to be obvious to incite the player's curiosity on his motives. Alvin's personality is the personification of Jude's adult personality if the events of "Tales of Xillia" did not occur. Since his debut, Alvin ranked on the "Tales" character popularity polls.
