Apollo opens up by stating the Three Syndicates that run behind the scenes around wrestling:

Mafia City who distributes "daily doses", The Sonozaki Family which is a strong political group, and finally an unknown family known for it's blood thirst.

Amami ends the meeting with a warning: They're ending this murder case, so don't do anything unnecessary.

Afterwards, a strange girl tries to take her with some kind of magic but Beato denied it.

Episode 3

Apollo is distraught that no one is taking the case seriously, as if nobody cared he died like it was a curse that must not be mentioned.

Amami tells him to calm down, and shares his same thought as Beatrice, who uses the red for truth:

Apollo tries to look into the vents, but Amami stops him saying that they are gonna END this murder case. They don't need to know the culprit is yet.

He puts a shot put ball in the vents and claims that if he's still lurking, they'll hear when the ball hits him.

Episode 4

They fight the CIA glow in the darks for clues.

Episode 5

The Bystery Busters are drafted to The Final Rumble.

Apollo is disappointed in this, especially that they weren't unable to accomplish anything, but Amami and Beato just say the truth that no detective currently in BCW cares about the case. Amami adds that they probably do care about the rewards, and hopes that someone may eventually solve it.

Apollo is irritated and even says that he was suspecting Micah Bell due to him being affiliated with neither brand yet attacking people backstage. Amami just tells him he's reaching, but Beato just retorts that a manslaughter would make for too lame a mystery. Still, Apollo hopes they can meet that guy in TFR.

Amami checks on Apollo to see if he got attacked after hearing him talking alone, but Apollo sways it away. Beato thinks it a shame his body wasn't found as closed room murder.

She later shows up late for their match.

And he does.
