Madoka Folger-Tsuchiya. Any pronouns are allowed...except it/its.

Not much is known about her, except her beloved hometown in Atumé de Bangalter-Christo municipality locates 47 miles away from Vresilvina, which she temporarily leaves for the sake of pursuing higher education at a well-established public university in Vresilvina, her deep love of music and DJ sessions, and the fact she never misses paying rent to Casita Override every month...even though the Casita actually let her live with them rent-free.

Not to mention that just like Kaiserine, she is constantly mistaken for a young man by some people because of her flat chest and obvious masculine traits, although she will simply laugh it off casually. 

However...

For a 19-year-old, 5-foot young lady whose favorite color is Black (#000000), she is quite impressive as one of the official Casita Override members.

All for some weird reasons that even nobody can explain properly. For real.

Kaiserine, Noel, and Walpurgis always describe her as someone who looks emotionless at a glance...but turns out to be caring, selfless, cheerful and friendly to everyone. 

Even Madoka admits that from the moment she exists, she simply has no interest in any form of romantic and sexual relationship, and she is already happy with having a lovely and supportive family, the Casita end up being her genuinely trustworthy and caring friends despite their respective quirks, her lively musical passion and other platonic matters that she truly enjoys.

Unlike her friends, she is the only human in Casita Override with her elemental codename Irizenna (lightning sound in conlang) but for some weird reasons that, again, nobody can explain properly...

...she still has no idea regarding the origin of lightning element she currently masters so well...

...despite her majestic abilities that basically come out of nowhere to infuse her lightning element with her beloved harp bow, and occasionally, her beloved DJ equipment...
