Synopsis

In Doctor Y, Kaji Hideki (played by Katsumura) has woven a series of bittersweet and diverse stories, crossing genre boundaries with each episode. In the second installment, he gets spooked by a ghost incident while on night duty; in the third, he faces a crushing defeat in a bid for professorship. In subsequent seasons, he’s been cornered by dramas involving a secret child, surgical mistakes, and heartbreak, yet each time, like a phoenix, he rises again.

This time, however, Kaji finds himself at a breaking point, facing “unprecedented trials.” Sent to Singapore on an errand for Toitei University Hospital, he unwittingly stakes it all on a massive gamble—and spectacularly loses. To make matters worse, he squanders hospital funds, landing himself in a sea of debt. Adding to his woes, he receives a mysterious request from someone willing to take on his debts, but with one odd condition: “Do not let Higashimura Ren become a doctor.”
