Eru Chitanda from Hyouka - home economics

Houtarou Oreki from Hyouka - Logic

Satoshi Fukobe from Hyouka - History

Mayaka Ibara from Hyouka - Art

Fuyumi Irisu from Hyouka - Business/Management

Wakana Sakai from Tari Tari - English

Sawa Okita and Konatsu Miyamoto from Tari Tari - Muaic and Dance
     
Taichi Tanaka - Physical Education

Atsuhiro Maeda (Wien) from Tari Tari - Wrestling

Ayuko Oka from Mysterious Girlfriend X  - Math
