- Interestingly, PRTS is similar in tone to "Priestess."
- PRTS is the announcer of various events in-game, from an operation's outcome to RIIC-related functionalities.
- Before English CVs were added on the Global server and aside of Team Rainbow Operators (Ash, Blitz, Frost, and Tachanka), PRTS was the only character who speaks English instead of Japanese. PRTS' Japanese voice actor Yu Asakawa is also fluent in English as evidenced by her frequent tweets in English.
- The layout previews of an operation is displayed through PRTS' surveillance footage that is referred to as "EYESOFPRIESTESS".
- When the player closes the Arknights application during the second battle in 0-0 and reenters later, the battle will end immediately and a secret story will be loaded: Amiya will ask what just happened because Doctor said nothing but it feels time had stopped, and a secret voice says "The record indicates that Dr. {nickname} has switched the active application." This voice may be PRTS monitoring the system.
- After the secret story the battle will be restarted at Amiya's instigation.
- In 3rd anniversary The Journey Together special retrospective, if player has an Operator as the assistant for 1000 or more days, PRTS will figure out the Operator "had experienced one thousandth of the hard work of the system". Thus PRTS has already worked for at least a million days (i.e. ~2739 years).
