Algodoo

The way Matteo acts in this trial really caught me off guard. I feel as if it's normal for him to be suspicous, and i was pretty sure him and royal were friends. But accusing one with only one "claim" seems a bit over. Kinda leaning towards him being the culprit even more now.

Time for me to clear my name

Oh! Maybe Royal and Blue worked together to kill Viscoui, then Blue double crossed Royal

It seems like Matteo did it, I think he is just blaming others so that he would be caught.

Wait, I know what they're overlooking.

The second bloodstain.

It was a darkish pink, unlike Maya or Clara's blood.

I was able to find out it was indeed Viscoui's.

I think I can figure this out from the beginning.

Here's how this played out:

The killer first asked Viscoui and Royal to meet them at different times. But, Royal wasn't second, as the killer had previously asked Royal to help them with a murder, which he agreed to.
Then the blackout came as Royal and the killer expected it to-6:25

At 6:28, Viscoui arrived at the arcade to meet the killer. Viscoui failed to see Royal behind one of the machines, along with failing to see a broken start button. Then, when Viscoui wanted to play some games, the killer grabbed the start button and burned Viscoui with it. This left Viscoui cowering in fear in front of the DDR machine.

Then, Royal jumped out from behind the same machine and repeatedly beat Viscoui's head in. It did take a while, due to the helmet Viscoui wore.

Then, the two killers set the scene back up.

They had used Ryan's toolkit to frame him for the crimes, which is why the hammer was the weapon.

After about 5 minutes, the scene was just how they wanted it.

The start button was back at the machine, the toolkit and weapon were where Viscoui's corpse was:another machine, in hopes of making it so everybody would believe Viscoui died there.

Then, the killer started on Phase 2.
They had done somethings to a few of the rooms to pin it even more on Ryan, such as leaving the laptop Ryan was using on.
The killer had also acquired rope from the curtains in the changing rooms, which is why they were on the floor.
The killer's Phase 2 was much more confusing.
They grabbed the hammer Royal used and used the hammer on Royal until he was knocked out.
Then, the killer dragged Royal out into the soccer field, where they hung Royal by his legs and waist.
Then, Royal awoke, and fought back, but the killer was prepared.
The killer strangled Royal with some of the rope, killing him after some time.
Lastly, the killer tore off a piece of Royal's scarf and left it in the soccer field, and also replaced the hammer.
If the framing of Ryan didn't work, they had wanted to frame Blue, too.
But what they forgot is that Blue and Haysuba found both bodies in the first three, meaning they're safe.
But the true killer of Viscoui Voui and Royal Niyomiya is...

Amai Umi, the Ultimate Astronomer.
