Уса Кадзунарі

Usa Kazunari is a high school freshman whose parents had to move away for work. He agrees to stay anywhere, as long as he could live on his own in peace and quiet. Having grown up surrounded by his parents' eccentric friends, Usa feels that unique individuals tend to gravitate to him resulting in what he considers a disastrous three years in middle school where he gained a reputation for handling odd people. Although he initially balks at the idea of rooming with dysfunctional people, he decides to stay at the Kawai Complex and quickly adjusts to its residents' behaviors.

His favorite dish is salisbury steak.
