SSS Lieutenant/Synopsis

History
When Yuri Briar first joined State Security Service from the Ministry of Foreign Affairs one year before Operation Strix, the Lieutenant was curious as to why the Boss recruited the young man. When he asked the Boss, he answered: "The kid's adorable, am I right? Like a cute little puppy!" As they worked together, the Lieutenant recognized that Yuri was good at getting things done, noting how indiscriminate he was.

Secret Police Arc
The Lieutenant and two SSS officers arrive at Berlint City Hall to arrest Jim Hayward under suspicion of espionage. Hayward attempts to resist, so the officers knock him unconscious as the Lieutenant says they will hear his confession at their agency. As the agents take Hayward away, they frighten the employees witnessing the event, including Millie.

The Lieutenant takes Hayward to an interrogation room and asks him several questions concerning the files Hayward stole. When the man does not answer, the Lieutenant has him beaten up. After asking again, Hayward asks to be sent home, and the Lieutenant responds by burning Hayward's hand with his cigarette and suggesting that they start having a more productive conversation. Yuri arrives to take over the interrogation at the Boss' request and swaps with the Lieutenant. Outside, the Lieutenant's subordinate asks why the Boss recruited Yuri, and the Lieutenant tells him what the Boss told him back then. The subordinate chalks it up to Yuri being a mascot, which the Lieutenant says is something they might need considering the nature of their job, but not before adding that Yuri is skilled with his work.

The Lieutenant comes to work the next day and finds Yuri covered in bandages. He asks the young man what happened, as he knew that Yuri went to celebrate his sister's marriage the night before. Yuri says he cannot remember, and the Lieutenant assumes that Yuri must have gotten drunk and picked a fight with her husband, then reminds him to quit drinking. Yuri insists that his sister's husband does not deserve her and accuses him of being a con man and spy. The Lieutenant tells Yuri to calm down and asks if he has any proof. Yuri realizes he should have done this but starts banging his head against the locker after his thoughts run wild. Watching this, the Lieutenant wonders if Yuri's wounds were self-inflicted. As the Lieutenant has a smoke, he tells Yuri to get over his sister complex and focus on their job, which is to catch spies like Twilight, which, in turn, will ensure Yor's safety.

Midterm Exams Arc
After Yuri survives getting hit by a truck after being light-headed from pulling four all-nighters in a row, the Lieutenant is concerned for his subordinate and warns him to be careful, but Yuri assures him that he is fine.

Imperial Scholars Mixer Arc
Yuri listens in to an illegal dealing, and after confirming that the deal has been made, the Lieutenant and his fellow officers bust into the room, declaring the men inside arrested under espionage. At HQ, the Lieutenant sees Yuri getting assigned another assignment by their superior officer and questions if Yuri is being overworked. Yuri assures his captain otherwise, saying that he can handle it. Later, the Lieutenant visits Yuri, who has been meticulously observing his target, journalist Franklin Perkin. The Lieutenant is impressed by the amount of intel Yuri has gathered on Franklin and tells Yuri to rest after pulling two consecutive all-nighters, but Yuri says he is fine. As the Lieutenant reads out the report, Yuri twitches in response to words sounding similar to Yor, so he tells Yuri to rest.

Yuri and the Lieutenant hear Franklin leaving his house and proceed to tail him. Watching from behind a corner, the Lieutenant notices that Franklin is looking for something to write about. The agents then watch Franklin bully some children. An angry Yuri attempts to confront Franklin, but the Lieutenant holds him back, telling him to wait until Franklin leads them to the publisher buying his articles.

Cruise Adventure Arc
Yuri catches a cold and collapses while chasing a suspect, as his immune system breaks down whenever he remembers that Yor is away. The Lieutenant takes care of him during his illness and, at Yuri's request, buys a special herbal tea which reminds Yuri of the awful taste from his childhood when his sister tried to cure him. After throwing up this tea, Yuri is keen on resuming his work, which the Lieutenant quickly rejects.

Red Circus Arc
Two Eden Academy school buses get hijacked, and after an SOS message by Becky Blackbell is dropped onto the streets, the Blackbell Company shares this information with the SSS. They ascertain that the perpetrators are remnants of the extremist Red Circus group. The Lieutenant reports this to his superior officer and adds where the buses are headed. The Leader says that suppressing the suspects is their top priority and orders the Lieutenant to cover up anything regarding the hijacking. After the briefing, Yuri approaches the Lieutenant, asking about the incident since his niece, Anya, is on one of the buses. While the Lieutenant wonders who informed Yuri, he tells Yuri he cannot come because Anya might recognize him and warns him not to tell City Hall. Yuri is initially compliant, but after a dark thought passes his mind, he runs after the Lieutenant and tells him to wait for him, to the Lieutenant's dismay. To prevent him from going, the Lieutenant has Yuri restrained to a pillar.

Mole Hunt Arc
Out on the streets of Berlint, the Lieutenant finds Yuri tailing Loid with Yor and signals to him that there is an emergency summons. Afterward, he, Yuri, and several SSS agents are informed by the Boss that they are expecting a mole to return to Ostania, and he orders them to secure him once he crosses the border. The agents head to Shellbury in northwest Ostania to meet with the mole, Winston Wheeler. Yuri and the other agents discuss the covert nature of this operation, and the Lieutenant reminds them not to draw attention to themselves. He adds that if WISE or Twilight showed up to interfere, then this would be the most opportune moment to catch him. Yuri is later approached by Wheeler and confirms with the Lieutenant that he is talking to the real Wheeler.

Yuri and the Lieutenant get word that the Winston they encountered was actually Twilight in disguise and are ordered to search the park for him. There, Yuri finds his footprint on the ground, even though this is his first time in the area. Yuri points this out to the Lieutenant and hypothesizes that Twilight is beginning to panic by leaving a track heading to the sewers. Yuri descends below to give chase, but the Lieutenant tells him not to act without orders. Yuri reasons that this is the best opportunity to catch Twilight, so the Lieutenant decides to call for backup to guard the sewer exits.

The Lieutenant and Chloe go down the sewers and find Yuri unconscious and beaten. After Chloe wakes up Yuri, the Lieutenant deduces that Twilight beat Yuri and asks how long ago it was, to which Yuri says he was out for about fifteen minutes. Knowing that Twilight could have covered a lot of ground in that time, he orders Chloe to bring Yuri back outside for medical aid and leaves to pursue Twilight by himself.
