Stelsa is an ambitious and forthcoming business person, with an internship as an auditerroriser under the Alternian Government. Upon meeting the player, she offers the player her business card and services, indicating that she is quick to take every opportunity available to her. She fully intends to become the best in her field, which is why she takes on numerous side-jobs to gain new experiences. This is the main reason why she's going all-out to impress her potential client--in this case, Remele. Her desire to succeed keeps her extremely busy, which is reflected in her tendencies of overworking herself. When she admits that she believes reading Remele's webcomic is an irresponsible and flippant way to spend her time (despite enjoying it), the player has a hard time encouraging her to allow herself time to rest and relax as Stelsa misunderstood the player. Overall, Stelsa seems to be the sort that places ambition over comfort.

She is extremely confident and self-assured when it comes to her work and schedule, though there are times where she loses her composure. This is best illustrated when the player openly speaks about Tyzias' insurgent views on Alternian society, Stelsa quickly dissmisses the player's insinuation that Tyzias is involved in anything treasonous. When the player probes further, Stelsa flies off the handle and becomes near hysterical in demeanor in her attempt to defend herself. However, should the player back off, Stelsa simmers down quickly enough. 

Apart from that, Stelsa appears to be quite friendly to those she meets. Even though she'd only learned about the player from Tyzias, Stelsa doesn't mind offering the player a drink and a snack right after inviting them into her hive. She also has a tendency to refer to the player as 'darling' every now and then, hinting that she's rather affectionate in nature. 

Stelsa is noted to speak in a rushed manner, making it hard for others to get a word in edgewise. The player describes the entire experience as being struck by a verbal freight train, and is quite amazed that Stelsa is able to say so much without drawing breath or pausing in between sentences. In addition, Stelsa has toned arms; results from exercising often (there are dumbbells in her living room and a stepper tucked away in a corner).
