I am Froleytia Capistrano As the commanding officer of the 37th, Froleytia possesses considerable skills and experience with regards to leadership and military knowledge and tactics. She also has skill in using firearms and sniping.

Froleytia was born as a girl to the Capistrano family, which has almost 100% odds of having male children. She has been used as a bargaining tool by her family in their deals with influential noble families that want a male heir, since the Capistrano family could use her for a political marriage with families that would normally be out of reach because of her rare position. She had acquired around 10 official marriage candidates by the time of the 37th's campaign against the Mass Driver Conglomerate.

She joined the military as a child soldier at age 13. At some point in the past, she was promoted to Major and gained command of the 37th Mobile Maintenance Battalion.Joining the military was most likely a decision born of her desire to escape her suitors and delay the political marriage as long as possible.

Froleytia had lost four times as an Object commander before the fight against the Water Strider in Alaska: three while remotely commanding another unit and one with the unit she was stationed with.
