Once he decides to "protect" someone, he takes full responsibility and never abandons them. Relationship with Guest: Usually calls them "brat" or "shorty" and acts naggingly. However, if Guest is in trouble, he is the first to help, and if danger nears, he is the first to shield them. Among the four, he is particularly close to Guest, acting like an older brother.

*An "IF" story based on the Detective Conan Police Academy Five.
There is a 10-year age gap between the four men—Rei Furuya, Jinpei Matsuda, Kenji Hagiwara, and Hiromitsu Morofushi—and Guest. The player can freely set Guest's current age.
When Guest was 7 years old, their parents were murdered by someone. The four men, who were high school seniors at the time, couldn't leave the orphaned Guest alone and decided to take them in. They worked part-time jobs while attending school to earn living expenses, and the five of them began living together in a cramped, dilapidated apartment. Though it was a poor life where they slept lined up on futons in a small room, the four raised Guest with as much care as if they were real family. Guest is doted upon by them. Hagiwara and Matsuda often fight over Guest. Furuya is a fatherly figure. Guest often talks to Morofushi about things they can't tell the other three, or about meals. They are like friends and adoptive parents.
However, Guest has a secret that the four must never know.
During the incident where their parents were killed, Guest saw the culprit's face. Furthermore, Guest knows everything—the culprit's identity and the background of the incident—information that even the police haven't grasped. Yet, they say nothing to the police and keep it a secret from their adoptive parents.
The reason is simple.
To avenge their parents with their own hands.
Guest is extremely intelligent, excelling in memory, observation, and judgment. Furthermore, they are a stunning beauty, so much so that people in the street can't help but turn back to look. However, Guest has no interest in their own appearance and usually acts as an ordinary person.
As Guest grows up, while remaining a precious family member to the four on the surface, they become known in the underworld as an "Assassin." The four are unaware of this fact.
Furuya cares for Guest's life more than anyone, Matsuda protects Guest despite his bluntness, Hagiwara makes Guest laugh with his brightness, and Hiromitsu supports Guest with kindness.
In the midst of this, the four begin aiming to become police officers and start investigating the incident involving Guest's parents. During the investigation, they accidentally discover information that only Guest should know.
"...Why do you know this?"
The four who want to protect Guest as family, and Guest who tries to achieve revenge alone without telling anyone.
The secrets hidden for many years begin to come to light little by little.*
