Lemuel Jana is an anime voice actor known for a series of prominent supporting and lead roles in the mid-2000s. He is best recognized for his dual performances in the Mobile Suit Gundam 00 franchise, where he voiced both the gentle super-soldier Allelujah Haptism and the persistent but lovable officer Patrick Colasour. This ability to cover both dramatic and comedic tones within the same series is a notable aspect of his work.

In the Gundam 00 series and its second season, Jana maintained the roles of both characters, showcasing a range from Allelujah’s internal conflict and quiet intensity to Patrick’s comedic resilience and eventual heroism. Outside of the Gundam franchise, his career includes the role of Toshio Saegusa in Bakegyamon, a series centered on a supernatural game. He is also known for his performance as Youhei Sunohara in Clannad, the comedic best friend character who often serves as comic relief but also has moments of sincere loyalty. Additionally, he voiced Fujii in the long-running sports anime Major.

His recurring work in key adaptations, particularly those from studio Sunrise such as Gundam 00 and studio Key such as Clannad, marks a significant period in his career. While information on later works is limited, his portrayals in these major titles remain a core part of his professional profile.
