Kasennen (Katyayana), from the series "Two Bodhisattva and Ten Great Disciples of Buddha Sakyamuni (Nibosatsu Shaka judai deshi)"

The debating skills of Kasennen (Sanskrit: Kātyāyana) are legendary, although here Munakata Shikō chose not to depict him speaking. Instead, he wears a conflicted or doubtful expression.
