Sorry for not doing the previous challenge
My main suspects are Blue and BlackBot, they have been watching security cameras the whole time with Sky (i dunno where).
Killer: BlackBot
I dunno what his motive was, but for me, it just makes sense for BlackBot the be the murderer. Let's just look over it.
When BlackBot and Sky were setting up the cameras, BlackBot secretly put something in the cameras so that if he would press a button (that he also made), all cameras would go off at once.
When afternoon almost ended, BlackBot quickly went to the kitchen and took a knife, and quickly went to Sky and Blue, who were going to the place where they were watching the security cameras. They all waited for something suspicious to happen. When Minty Fresh and i were going to our rooms for uknown reasons, BlackBot waited until we left, and then pressed the button, making the security cameras go off. Blue and Sky were suprised, because they thought the cameras were set up with precision. While Blue and Sky were distracted, BlackBot knocked out Blue, and cutted of Sky's head, killing him. However, BlackBot realized that Sky screamed so loud, everyone could have heard him and run to the place were they thought they heard the scream, so BlackBot knocked himself out so that everyone would think a different killer knocked him and Blue out, and cutted of Sky's head. This could also cast the suspicion to me and Minty Fresh, since we went to our rooms, and later left for unkown reasons. But that's just a frame... a killer's frame... BlackBot's frame.

Killer:BlackBot
He killed Sky

how am I spared and scared

rainingmoneyx is right, why is he spared and scared at the same time?

Srry. It was a mistake. I didn't notice it until you pointed it out. THX. <:D

ok

killer-yellow
reason-YOLO

i dont even look like i hamged myself *FFaceplam*

I was too lazy ok.

Wow, there's another one!
Brainstorming:
Well, Colorless, Cy-Blu, Cyan, and Turquoise weren't really in the description...
This is my guess:
Killer: T. Turquoise, Turquoise's counterpart(dun, dun, dun!!)
Killed: Cyan
I mean, *laughs*, she got a knife, maybe she hated Sky enough to kill him? Really that's all!
...

Killer: Yellow

Reason: Well, Yellow was worried that he might die so he wanted to kill someone. So Yellow was spying on Sky and realized that they are watching the security cameras so when Yellow walked in his room, he hacked the cameras on his laptop and when the cameras shut off it was his chance! went in the room knocked out blue and blackbot and chopped sky's head off

Killer: Yellow
Reason: just nothung but yellowyellowyellowyellowyellow

Killer: Yellow
You can never be sure with these new cases, anyways, Yellow had been scared because of all deaths, to avoid it, Yellow must kill somebody, to do that he knew that the other people would make security cameras, to avoid it, Yellow got all the information he could gather, then, set up the death procedure, when the cameras stopped, Yellow knows the other people will be confused that the cameras malfunctioned and really quickly Yellow knocked out Blue and BlackBot and then he chopped Sky's head off.

From the evidence i've gathered, I can conclude that Cy-Blu is our killer for cases 5 AND 6.

Let me explain the 6th case.

Once Minty and Yellow left their rooms, something happened to the cameras. They were shut off, right? Cy-Blu's got a spear! He could just use his spear to switch the cameras off without being spotted.

Once the cameras were switched off, Cy-Blu went right to the murderous part of his plan. He went into the room the camera-watchers were in. He first used a heavy, yet unbreakable object to knock out BB and Blue and then went for Sky.
Sky was scared, and cowered in a corner, but Cy-Blu killed him anyways. He got out a knife he took from the kitchen after disabling the camera that was there. He used all his strength and cut off Sky's head, leaving it to roll on the ground. He left the knife at the scene and ran with his spear.

That is what I think Cy-Blu did to this Case.
