A young Sister of Meropis who was born on Tlaloc Station in 3287. Born to a wealthy family that can trace their roots back to Earth, she chose to join the Sisters upon their revival in 3304 and, enamoured with the tales surrounding the legendary Commander Suhono, who had revived their order, chose to pursue a vocation as an independent pilot. She completed her training in 3306 and took Commander Suhono's given name, Arini, as her religious name. To differentiate herself from her hero, she added the number 108 — the number of Sisters who flew aboard the Astral Dream Collector to Beagle Point — to her name. She aspires to live a romanticized version of Commander Suhono's life as an explorer and trader, blissfully unaware of her many crimes. Following Commander Suhono's retirement, Sister Arini-108 is the only professed Sister of Meropis who flies as a Commander. In 3307, she inherited the Anaconda-class "Pale Moon of January" from Commander Suhono and began using it for exploration.
