Kōsuke Fujishima
Character designer Kōsuke Fujishima noted that while Luke's clothing makes him look lazy, it was okay to have clothes that are outrageous since the setting was designed to have him wear the most fashionable clothes of his time. He decided to show Luke's abdomen to demonstrate that he was a combatant in the game. Fujishima remains anxious about Luke's design wondering what people think about his abdomen always showing. Luke's pose is the result of Fujishima's research in fashion books which feature images of boys who look like they hang out at Shibuya.
