Ganya

Ganya is exceptionally interested in researching and repairing mechanical structures. Taking things apart and then putting them back together are things she has enjoyed doing from a young age, and it's rare that there are ever mistakes like having a bunch of leftover screws after reassembly.
Mander Mine is home to numerous workers who once played a part in constructing Bonfire Cities and railways. These elders were all pleased to see such a diligent, driven child. When Ganya goes back to her residence in Mander Mine now, she still greets them happily as she always did.
As for the person who had the greatest influence on her life trajectory, that would be her paternal grandfather, who joined the Bonfire City engineering team after Solstice and personally participated in the early development of Shoggolith City when he was still a man in his prime. In his humble abode, Ganya listened to him tell one after another story about how he and his companions traveled a long time to construct a city, how the buildings were built from the ground up, and how the tracks were laid miles and miles away, which filled young Ganya with eagerness for the outside world and the future.
However, her grandfather's stories always came to an abrupt end. "Shoggolith City was constructed, and a railway network was built across the land." That marked the end of the journey between him and his companions. Only after he passed on did Ganya comprehend why he looked so forlorn, and thus she decided to venture out into the world outside of the mine.

To Ganya, structurally sound and highly efficient machinery is very attractive. Laymen admiring such machinery may simply give basic compliments like "That's amazing," but Ganya will seriously look into how it works and study the good points in its design. Ever since taking over the power hammer left to her by her grandfather, one of her goals has been to become an outstanding machinery designer; thus, she and the Conductor do have some common topics to chat about.
At times, Ganya will put in the work to make some mechanical handicrafts, so it won't be a surprise if you bump into her in all sorts of parts stores every now and then. Lately, she has started giving out her handicrafts to various friends, often surprising them with her out-of-the-box creativity. For instance, she gave Rachel a ribbon bow made out of gears, gave Reika a keychain made out of discarded pull tabs, and gave Ilona a diorama in a tin can... Being Ganya's friend and teammate sure is a pretty delightful thing.
Tools and weapons repaired by her also tend to have more "personality." Her own weapon, for example, was originally a claw hammer that she transformed into a dual-purpose mechanical axe that's still able to function as an everyday tool outside of the battlefield. In a way, Ganya believes this is how she can fulfill her grandfather's dying wish.

"Ganya is an ultra-zealous person!" said Rachel. This sentence might sound incredibly absurd, but even Reika and Ilona would nod in agreement, as Ganya had a goal that she almost never told anyone else.
Ever since her grandfather passed on, she had been quietly creating the prototype of this goal in her mind, pretty much already determining her direction in life: She intended to build a more equal world that lets people live with more dignity. However, no matter who she could tell this to, they would probably just laugh it off. After all, what could a mere BCRL Agency branch administrator possibly do to make the world a better place?
Ganya was well aware that she was powerless, but she did not give up her goal and instead turned it into her own code of conduct. Before doing anything, she would first consider the consequences in detail. Her aloof nature and much more cautious method of doing things made her appear way more mature than people her age, which was how she won over her teammates with vastly different personalities. Ganya might look like she was set in her ways, but no one other than Team Meerkat's members knew better about her beyond-sincere heart.
It's to be expected that she will be encountering more things and people in the near future. Even though her goal remains a pipe dream as of now, Ganya is still doing everything she can to achieve it.
