Marine Star Pearl is seen keeping up a low profile amongst the string. Delicate footsteps that barely make any noise, mangled skin covered by Abyssal Reef's designated preferred uniform or whatever matches their aesthetic, could he say. He's there when you need it, but obnoxiously quiet otherwise, tending to his and his roommate's personal duties. Whenever given the chance to speak, their sentences are absurdly long yet feel short in all meaning- a whole paragraph that only lasts a few seconds. His voice is charismatic and awfully comforting at the same time, though not enough to drive you in. An ease to the soul would be the best way to describe it.

As seen with his interactions with Firefly during the first episode, Asterias tries to keep up a strong temper. Tough exterior and a bright grin on his face at all moments while assisting gems who truly need companionship. So much so that he plays silly moves for those who need him. For example, offering a hand or tapping your shoulder when asleep. His true beliefs and motives? Up to you to find out, but he's a sweet guy to come across. So it seems, at least.
