Yūsuke Saitō is former subordinate of Misaki Kirihara in the Japanese Police.


Saitō is a tall man, standing at 195cm tall and has short, dark hair and think eyebrows. He normally wears a business suit.


Despite being an officer, Saitō seems to have little common sense as he infiltrated a gang operation undercover using his real name. He has admitted to finding Kirihara scary. However, Saitō is loyal to Kirihara and protects her from harm, even when he thinks she's frightening. It is revealed in the OVA that Saitō has feelings for Kirihara, however soon after verbalizing them his memory along with Kirihara's is erased due to a memory erasing substance accidentally released by Mao. He still works in the Department, but secretly maintains his contact with Misaki. Saitō is a 2nd stage in both judo and karate.

S2E4 Saito on phone to Misaki

Saitō secretly talks to Misaki on the phone.

After transferring to the Hachijo-Jima station and witnessing the disappearance of BK-201's star, Misaki calls Saitō and discusses the situation. However, she is interrupted by Goro Kobayashi and after a short discussion with Kobayashi, she hangs up on Saitō, who is shouting to get her attention.[11] Upon taking up her new job in Section 3, she talks to Saitō by phone. He asks her why she resigned from the police without telling him and the others. Concerned by the turn of events, he becomes agitated and demands to know if she is getting herself in to a dangerous situation. However, Mina Hazuki grabs the phone off of Misaki and tells him that Kirihara is not her name, then hangs up on him.[12]
