At the start of the game, you’ll learn the game basics of tailing someone but also how to fight.

The Red Square means you have to get there to start the cinematics to cross over into the next part of the story. Acting Casual is used to deflect your target’s attention, when he spots you while tailing. You can only use this option, when the target sees you. Otherwise it’s inactive at the center bottom.

After some cinematics, you will be asked to take a picture of Kosuke and a woman. Ready the camera and try to meet the requirements.

Here, you’ll need “In focus”, “Taken at max zoom” (use the controller sticks) and “Kosuke and woman both smiling”. For the last one, you just have to wait a bit until the box is ticked. Then take the picture.

While continuing to tail Kosuke, you will be recognised by “Street Punks” and you will be introduced to fighting with “Crane Style”.

Meet the these Tutorial Objectives to continue:
“Square” to Attack (9x)
Move while holding a fighting stance with R1 (5x)
Guard against frontal attacks with L1 (3x)
Press “Cross” while holding a fighting stance with R1 to evade (3x)

Follow him into the POPPO convenience store and take a photograph of Kosuke withdrawing money.

Requirements to meet “Excellent”:
In focus and Taken at max zoom (with controller sticks)
Includes the ATM screen
Includes Kosuke’s face

Active Search Mode: Secure the Infiltration Route

You’ll tail Kosuke to a building with a guard in front. Now, you enter Active Search Mode where you have to look around and zoom in to:

“Look for an entry point”:
One of the windows in the first floor are open. Zoom into it.

“Look for a foothold”:
You can walk in Active Search Mode. Walk into the near alley and zoom into the A/C Unit.

The starting point to sneak inside has a nice yellow arrow. Now you get the Parcour – Grip Gauge and Climbing Walls tutorial.

Use the instructions to get inside the building. While fighting the Street Punks, you’re introduced the the Tiger Style and Ex Actions.

Meet the these Tutorial Objectives to continue:
Attack with “Square” then “Triangle” (3x)

EX Action (1x)

Leave the room after the fight and go to the red triangle as indicated. Target the thug and “look” when indicated.

You can’t get passed the guy with the golden jacket Go through the other door instead. In the next room, a thug is sleeping. The exit door is locked, so you need to get the keys on the table next to the sleeper.

Go outside and up the stairs to the locked door, where you are introduced to lock picking. Move every pin up so it turns golden. Open the door and go to the red square.

Look at the guard and toss a coin to the marked location to practice a stealth takedown. Now you can enter the Tatami Room.

After the cutscene you have to fight Kosuke and the Street Punks.

Meet the these Tutorial Objectives to continue:
R2 to EX Boost (1x)

Next is the Chase Tutorial and how to recover health during the chase.

Talk to Genda in his office, then go downstairs and talk to Kaito. He’s waiting at the minibus right in front of the office. Head to the bar.

Fight the Shady Bar Owner.

Head back to the agency. There is a marker on the map in which direction you need to go. Once in the office, talk to Kaito.

In Yokohama, head to the Yokohama 99 Detective Agency. On the way, you have to “Teach the Punks a Lesson”, where you learn “Fighting with Snake Style”.

Meet the these Tutorial Objectives to continue:
Guard against enemy attacks with L1 (5x)
L1 just as the enemy attacks (3x)
“Triangle” against a scared enemy (1x) – scared enemies have a blue glow.

After meeting Suriura and Tsukumo at Yokohama 99, head over to the Kyoinro restaurant to meet the client.

Back in the office, you will have to solve the Skateboard Detective vs. the Reseller Side Case before going to sleep at the couch.

The next morning, you’ll learn how to put on disguises. Choose the Work Clothes in the menu.

Then, take a taxi to the school.

At the school, follow Kaito. You will set up cameras automatically for a while. When you split, walk upstairs to the 3rd floor.

There are 3 camera positions in this part:
-> Staircase between 2nd and 3rd
-> Toilet
-> Staircase between 3rd and roof.

Exit Observation Mode and talk to the Janitor. Tell him you’ll report him for smoking. You then install the last camera and meet with Kaito on the second floor.

After the cutscene, enter classroom 2-2. When the teacher arrives, tell her the chairmain hired you. His name is Okuda-san (see “Go to Kyoinro” above). You can now “Head to the Gymnasium” to meet the others. Just follow the markers on the minimap.

Go back from the roof to the second floor inside classroom 2-2. Approach the girl and go into Observation Mode to “Observe the Bullied Child”. Examine her hand and her head.

Also her back and the notebook on the table.

In the Chairman’s Office, answer the question with “The Onlookers are the problem”.

Go to the second floor as indicated in the mini-map. The cinematics start as soon as you get to the camera. After the cinematics, you have to parcour up the pipes and drop on the other side.

The path now is more or less guided. Sneak over to the ladder to the roof and get on the roof. After the Long Jump introduction, start running towards the marker and jump. Climb inside the building through the open window.

Go to the red square and look at the guard.

Go down the staircase, where the guards just where and position yourself on the red square. Look at the guards.

Go back up to the roof and look at the guard. Here you’ll get the Smoke Ball introduction. Throw the Smoke Ball and go through the roof door while the guard can’t see you.

Cross the roof. Take as much distance from the guards as you can. Enter the building again at the other side. Go down, to the red square where you can toss a coin to distract the guard to sneak past him. There is another red square in the corridor. From here you can distract another guard with the coin just before you can enter the classroom.

Go to the girls desk, where you will start to install the speakers. When you’re finished, the Rowdy Students will spot you and start a fight. Here you’ll learn about “Deadly Attacks” and how to avoid them. After the fight, head back to Yokohama 99 and rest up on the couch.

It all began in the ’80s when I was just 7 years old. Starting with basic arcade games, I soon delved into titles like Loom and Monkey Island by Lucasarts. Throughout the years, as I indulged in more and more games, I consistently sought clear guides to swiftly navigate my gameplay. Now, it’s my turn to contribute back to the community.
