This I am happy to say I draw her myself :)

Complete name: Rowena Remington Sciurus López

Species: Albino White Squirrel.

Age: ????

Attire: Casual Attire, Mostly just a collar and her glasses much like his 2 brothers and sister.
Formal attire: Blue shirt with a green tie and green female waistcoat, at time. Sometimes pocketwatch.
Personality: Rowena being the female and apparently the “younger” of the brothers feels she needs to prove them both she can be as strong as they are. She deeply loves them both and it is a two-way feeling, both Remy and Cross look after her, sometimes makes her a bit pouty but she loves all the support she can get.
He is also even more perky optimistic and easygoing than her brothers. Once you get to meet her, you will know why she is also eager to support others mostly in terms of cheering others and encouraging them to overpass their limits.
She feels she has a lot to give for her, for her brothers and for the sciura they are eager to protect.

Likes: Acorns, his fellow squirrels, cheering and being optimistic.
Dislikes: Betrayal, rude ones, those who see squirrel as inferior and weak ones, those who doesn’t believe in better change and pessimistic.

Background:
Her bio is also like her brother and sister. He just likes to think in him as a follower in the past actions, thought he also felt a bit of guilt for how the squirrels were treated too… he felt something had to change and after their sealing it did.
For Cross, Remy, Rowena and Emilia… their story was just forgotten for some time…

Fighting style: While she prefers not to get much involved into fighting, Rowena is very versatile in battles using what she can use to gain the upper hand. She preferred to keep distance between combats and because of that she became skilled with bows and ranged weapons. She has an excellent marksmanship and most of them time she hits her target. She also is proficient in healing magic to cure even the deepest wound.
