Kenichi Suzumura
Lavi was based on the title character of Hoshino's one-shot manga, "Bookman". Despite his lack of appearances in later parts of the story, where he mainly provides comic relief, Hoshino found the character easy to illustrate. In the Japanese version of the first anime he was voiced by Kenichi Suzumura, while in the sequel, "D.Gray-man Hallow", the role was taken by Natsuki Hanae. He also shares two voice actors in the English dub: Jason Liebrecht and Chris Patton.
