Tomohisa Yamashita
"Doctor Helicopter" candidate Kōsaku Aizawa (Tomohisa Yamashita) does his best in the medical care spot. This season takes place in the winter, starting on Christmas Eve where the doctors spend their holiday on lifesaving. The appearance of Keisuke Tachibana (Kippei Shiina) who shares a past with Kanna Mitsui (Ryō) seems to pose a threat to whether the interns will last through their last year of "fellowship".
