Tsurugi is a calm and modest officer with strong leadership. He is a righteous person, who dreams of putting an end to crime and eradicating all evil in this world. Despite his accomplishments, he deems himself to be inadequate, considering the fact that crimes keep continuing regardless of his efforts. Perhaps due to this, he has a strong desire to end crime, even attempting to stop the Killing Game early on by pinning monokuma to the stage wall.
