PA: Secrets Under Starlight (PA:SUS for short) is a Project Arrhythmia storyline centered around the mysterious disappearance of a dangerous weapon known as the Excorclipse, and the deaths of a group of Navigator Stars.

Detective Clarity has always wanted to prove that she could help solve the unsolvable, right alongside her (unwilling) mentor, Agent Shutter.

Now, with the stars aligned, she may have just been given her chance…

Together, they're chosen to locate the Excorclipse, and study the circumstances surrounding its vanishing.
But as they tread further into the dark, away from the glimmer of the stars, they soon find themselves entangled in a story of murder, deceit, and possibly; a full scale conspiracy.

Clarity always valued finding the truth, but what if the truth is, she isn't cut out for this?
Hopefully, with the help of her new mailman companion, she'll be able to piece it all together.

However, when the stars themselves have secrets, who can you really trust?
