The mysteries in Chapter Five are simpler than those of the previous chapters, but the Yurukill Judgment sequence at the end has new challenges that even experience players may struggle with. This guide will take you through both, paving your way to the game's climax.

This guide contains spoilers for Chapter Five of Yurukill.

The first stage begins as soon as Sengoku and Rina enter the corridor of the passenger car. You need to select a compartment that no other team is already investigating. The Crafty Killers team has already solved their case, so the door to their compartment is locked.

Keep opening doors until you find an empty room - in our playthrough, it was the door furthest to the right. Your task is to determine how the body inside was killed. The body can be examined in two parts, first the corpse itself then the head wound. Sengoku will note that the weapon left an imprint in the shape of a fox's head on the victim's skull.

Several items in the room have fox imagery. Examine the following items:

Once you've looked at everything, choose to give up searching and check a different compartment. The team will notice that the door handle could have been used as a weapon. Select the power drill to solve the case.

Select the left-hand door to start on the next investigation. You'll be sharing a room with the Sly Stalkers, and choosing either of the remaining rooms will result in your team being forced out by competitors.

Once again, you need to identify the murder weapon. Examine the body twice to find strangulation marks on its neck. Check all the objects in the room:

Once you've looked at everything, select the rubber bands and the hand towels to solve the case.

Start the third investigation the same way as the others, by examining the body. You'll discover that it is soaking wet, despite there being no water nearby. Check the following objects:

When you have examined every clue in the room, you'll proceed to a Yurukill Judgment Phase.

You're back in Sengoku's fighter craft for this stage, so it's back to basics in terms of tactics.

Give the following answers to maximize your lives for the Yurukill Judgment:

During this stage you'll be flying alongside the Yurukill Train. When it first appears it acts as an obstacle, but once you see warning indicators that show its guns are about to come online you can safely fly over the cars.

Be careful when the train moves to the center of the screen. After you see two gun turrets on the same car, destroy them then get out of the way. A beam cannon just offscreen will fire along the length of the train, hitting you if you aren't expecting it.

The cannon is the first boss; try to draw its fire to the sides of the screen while it's charging so that you can move to the bottom and shoot without worrying about the beam.

Once the cannon is destroyed, Binko's mech will emerge from the train car. She uses the same strategy as Rina used in Chapter One, so stay below her and position yourself between her laser bursts to keep the pressure on.

Once Binko deploys a Mind Wall she will periodically charge to the bottom of the screen. When she does so, fly alongside her and let your secondary weapons deal damage. You're mostly safe from her laser fire in this position, but watch out for the wandering purple projectiles.

The Mind Wall itself is protected by the mech's mask, so you'll need to position yourself slightly to either side in order to hit it. Alternately, an Outburst Bomb will do the trick. Upon breaking the Mind Wall, you'll enter Binko's first Prejudice Synapse. Select Drowning as the cause of death.

When you return to the battlefield, Binko will resume her rotation of shooting and charging. When she leaves the screen, be ready for her to suddenly re-emerge from the bottom before she returns to her starting position.

During Stage Two, the Yurukill Train will pass by on the sides of the screen, severely restricting your movement. Be careful not to crash into it and turn the limited space to your advantage by saturating the area with laser fire.

Between the train's turrets and the Binko dolls, you can expect to dodge a lot of enemy fire in this stage. Don't be afraid to frequently use your Outburst Shot to clear the field.

After the bullet-hell section, you'll be faced with two beam cannons on either side of the screen. The left cannon rotates like the one from Stage One, while the cannon to the right always fires directly to the left. Keep an eye on each one's current firing angle and shoot the cannon that you can most safely hit.

Technically, only the left cannon is the actual boss, so destroying it will allow you to proceed. Destroying the right cannon makes this easier, but isn't necessary as it will retreat if the left cannon is destroyed.

Next, you'll have to do battle with the Yurukill Train itself. The first train car is mounted with downward-facing lasers and deploys a handful of Binko dolls periodically. Stay between the laser shots just off from the center of the screen, and move up and down to avoid bullets from the dolls. Your Outburst Bomb can clear the field if things get too hectic.

The second car deploys a veritable army of Binko dolls, who both fill the screen with projectiles and block your shots from hitting the train. You can easily build up Outburst charge as you destroy the dolls, which can help expedite this phase with a well-timed blast. Use the same strategy for the third car, which deploys even more Binko dolls.

When Binko herself reappears, she uses the same tactics as when you faced her before. Once she sets up a Mind Wall, she lurks at the side of the screen while a beam cannon fires from the top of the screen. Binko will position herself to charge horizontally toward you, so try to lure her into staying near the top. That way you can focus your efforts on destroying her Mind Wall.

The cannon doesn't need to be destroyed, but if it's giving you trouble you can probably take it down within two to three of Binko's charge cycles.

In the second Prejudice Synapse, select the Map of Yurukill Land to pin down the cause of death.

When you return to the battle with Binko, a new beam cannon will emerge. Binko will spend more time at the sides of the screens, firing lasers and deploying drones. This is a better phase to destroy the cannon first, since you'll want fewer distractions during the short windows where Binko is charging and vulnerable.

When Binko is firing her lasers from the edge of the screen, she never quite goes all the way to the bottom. If the beam cannon has been destroyed, you can stay at the very bottom edge of the screen and attack without any danger.

Shortly after the third stage begins, two trains will appear on either side of the screen. Both can take a lot of damage and have limited firing windows, so your best strategy is to spend the early part of the stage charging your Outburst Meter then deploying a bomb when both trains are nearby. This also saves you the trouble of dealing with the hordes of Binko dolls they unleash.

Once the trains are defeated, Binko will merge her mech with the Yurukill Train, forming Kaiser Binko, the Bin-Bin-Bin-stigator. The Binko dolls in the corners of the screen will fire a large but manageable number of projectiles. The real threat are Binko's arm cannons, which cause a massive burst of bullets to spread across the screen.

To damage Kaiser Binko, you'll first need to eliminate the armor plates protecting the mech's body. These can take a cycle or two to break through, so be patient and watch for projectiles.

The second phase of the battle is comparatively tame. Watch out for warning indicators when Binko performs her jump attack, and focus on destroying the four Brain Barriers that appear shortly after the phase begins. There will be a few Binko dolls wandering around, but they can largely be ignored unless they're in your way.

Kaiser Binko's armor plates will regenerate at the start of the second battle phase, but if you destroy them a second time here they will not come back after you emerge from the Mind Maze. This can save you time and trouble during the final phase.

Once you've broken through the Brain Barriers, complete the Mind Maze clues as follows to solve the train mystery:

When the fight picks up again, Binko will start using her arm cannons again. Steer clear of her barrages and watch for her to start flailing her arms. When she does so, she is about to charge. Be careful not to be hit by the mech's arms while dodging!

Kaiser Binko will fly across the screen three times, deploying dolls along her path. She moves to quickly to deal any real damage, so focus on eliminating the dolls until she returns to fire her arm cannon again.

Binko's final phase sees her combine all of her previous attacks. In Story Mode, you can absorb the projectiles from her arm cannons to quickly charge your Outburst Bomb. In Score Attack, it's best to charge up during the previous phases and use a bomb at or near one hundred percent to finish the fight quickly.
