The current time is 8:00 pm. Suga is reading his investigation documents while sitting in the back seat of his black sedan, which the driver drove as usual. Nellson was sitting beside Suga while also reading Suga's investigation documents. The driver occasionally watched Suga from the rearview mirror as he drove.

"Are you working overtime again sir?"

Suga looked serious while reading the document and occasionally glanced toward the driver's back.

"There's no such thing as working overtime to be a Yokai Investigator, all hours are flexible hours."

The driver smiled.

"Right, I just hardly believe you still have to go to school sir."

Suga smiled.

"I can't leave it."

The driver looked curious.

"Did you find any clues from the mission you're on sir?"

Suga replied.

"Yes, the Hyena Yokai. He is pretty easy to find this time; recently, there have been cases of missing people around this area. When I traced them, the victim disappeared after working hours and usually used the train for transportation. We will start the investigation from there."

The driver's expression turned serious as he nodded.

Sometime later, Suga's car arrived at the side of the highway, with a wide sidewalk and stairs down to the subway station. Tall buildings and skyscrapers surround this place, and pedestrians are busy walking around. In Suga's car, he tidies up his investigation documents for a moment and prepares his black katana to bring. The driver watched Suga from the rearview mirror with an astonished expression.

"You will bring your katana in a crowded place like that sir?"

Suga nodded.

"Yeah, I could reason with just a katana, but for Nellson..."

Suga looked at Nellson with a confused expression; Nellson looked back at him with an astonished look.

"Should I return to my medium form first?"

Suga nodded with a disappointed expression.

"Yes, you better do that."

Nellson nodded. Not long after, pillars of black smoke billowed from all over Nellson's body and immediately enveloped him; this smoke then got smaller and disappeared, and a wooden keychain Nellson emerged from behind it. Immediately after that, Suga's gaze looked far away because he was blind again. Suga groped around, took the keychain Nellson, and tucked it into the inner pocket of his Yokai Controller Association overcoat. Suga groping around and took his katana Yokai Weapon. The driver, who paid attention to Suga, immediately looked reluctant.

"Do you need me to accompany you sir?"

Suga smiled.

"No, I'll go alone. Uncle had better be on guard if I ask for help."

The driver's expression turned serious.

"I understand sir."

Suga got off his car and used his sheathed katana as a cane. Shortly after, the driver drove the car away from here.

Suga carefully walked down the stairs to the subway station with the help of his sheathed katana as a cane while holding on to the handrails to his left. The people standing around and walking past Suga looked at him with various expressions, surprised, strange, or pity. Suga arrived at the train station, which is quite wide, extending to the right and left with a row of rectangular blocks of concrete pillars with long waiting seats in various parts of this station.

Suga tried to ask the people around him to call a security guard; a passerby then helped Suga and called the station's security guard, a middle-aged man. The security guard walked up to Suga; he looked at Suga in astonishment, especially because of the black sheathed katana Suga used as a cane. Knowing that Suga was blind, the security guard let him.

"I'm a security guard at this station, can I help you sir?"

Suga smiled.

"Yes, I'm a government investigator. For your information, what I brought here is a cane that has a unique shape, so there's no need to be surprised."

Suga said while holding his sheathed black katana with both hands and raising it to chest level. The security guard looked surprised.

"Okay?... I understand."

Suga took an envelope from his overcoat inside pocket.

"This is my assignment letter."

Suga gave his assignment letter in the envelope to this security guard, who then received it and read it for a moment. The security guard's expression changed in astonishment; he returned this letter to Suga.

"Of course, sir. What can I help you with?"

Suga put the envelope back in the inner pocket of his overcoat.

"I need access to the surveillance camera room."

The security guard's expression turned even more astonished.

"Of course, sir. Let me help you there."

The security guard then led Suga to the place he asked for.

After walking for a while, the two arrived in front of a single door with rectangular frosted glass above the doorknob. The security guard opened the door and invited Suga to enter. Inside the room is another male security guard, sitting at a table with monitor screens attached and neatly arranged on the wall. Seeing their arrival, the security guard from this room walked towards them. The security guard who was with Suga said.

"He is a government investigator, next I leave him to you, I have to continue guarding the station."

The security guard from inside the room nodded.

"Of course."

His fellow security guard walked out of this room and closed the door. The security guard from inside the room then walked towards Suga.

"Can I help you sir?"

Suga smiled.

"Yes, I would like to ask you to make a copy of this station's archive activity log for the past year."

The security guard looked surprised.

"For the past year sir? Did I hear right?"

Suga smiled and nodded.

"Exactly sir, for the past year."

The security guard replied.

"Something like that is in the archives room, not here, sir. Let me take you there."

Suga looked surprised.

"Is that true? Pardon my ignorance, can you get it for me here? Understandably, I'm blind, so it's a little difficult to walk here and there."

The security guard looked reluctant.

"Of course, sir. Please wait here and have a seat."

The security guard guided Suga to sit on a long chair against the wall; he then walked out of the room and closed the door. Suga was silent, sitting in his place while trying to listen to his surroundings and confirming that he was now alone in this surveillance room.

"Okay, time to call Nellson."

Suga took wooden keychain Nellson from his overcoat's inner pocket.

"Come on Nellson."

Shortly after, black smoke began to billow off the wooden keychain Nellson and grew bigger. From behind the smoke, Nellson emerged with the size of an owl in general. Suga and Nellson whispered something to each other, and not long after, Suga could see again.

Suga immediately got up from his seat, headed to the computer, and sat in an ergonomic chair before the computer monitor screens. Nellson flew and landed on the floor near Suga while looking at the computer screens. Suga operated this computer to see the camera footage from the past week. Nellson looked at Suga and the computer screens in surprise.

"What are you doing Suga?"

Suga took out his smartphone.

"I'm just looking for the hyena Yokai presence, does he ever act at this station."

Nellson nodded and looked even more curious. Suga connected his smartphone to this computer and started a program on his smartphone. The computer screen display began to move on its own, showing footage from several surveillance cameras in this station from the past few days.

“This program will quickly look for and detect certain traits, which I need even just one time he was caught on camera with matching features.”

The program begins to select the characteristics of the person Suga is looking for, starting from posture, dress habits, use of body language, face, and voice, if available. Before long, the program found what Suga was looking for. This program recognizes Nishiyama’s face, which is the face used by hyena Yokai as his human form. Nishiyama had just walked out of the train and walked across this station. Finding what he was looking for, Suga looked surprised. Seeing Suga, Nellson’s looked at Suga curiously.

“What’s wrong Suga?”

Suga came to his sense.

“I discovered the hyena Yokai using this program quite quickly and easily, even the accuracy rate above 80%, is almost like...”

Nellson appeared to realize something and cut off Suga’s words.

“He indeed wants to be found on purpose?”

Suga turned to Nellson, then nodded.

“Right, I don’t know if it’s true that he purposely makes himself easy to find. But it could just be my feeling because he might be negligent. Whatever it is, we’ll be waiting for him tonight.”

Nellson nodded. Suga operated this computer and put some sort of program so he could monitor and control this computer and surveillance cameras remotely. Suga disconnected his smartphone from the computer, put the earphone on his right ear, and contacted his driver.
