小清水亜美
Kobayashi allowed the voice actors who voiced his characters significant freedom to interpret them as they chose. There were a number of cast changes throughout the production; Ami Koshimizu, the voice actress for Tenma, had initially auditioned for the role of Yakumo, and between "School Rumble"s first and second seasons the voice actors for both Karen Ichijo and Yoko Sasakura were replaced. Mako Sakurai took over Karen's role from Yuuka Nanri, and Aya Hirano replaced Akiko Kurumado as Yoko.
