The oldest of Swallowtail's second litter, Arenul and Namib work together extremely well. The two are known for playing rough against each other, what with Arenul being the eldest and strongest, and Namib being the younger with a bone to pick. Libya occasionally joins in on the scuffles, but prefers to keep up a neat and tidy front. Now Ruapeha... well, the two work together as what amounts as the leaders, with Arenul taking charge of Namib and Ruapeha's borderline nitpicky behavior working in tandem with Libya's seemingly endless patience. Although being keen, she prefers to stay quiet and learn through her own means.
Out of all her siblings, it seems that this little one takes after her mother more than the rest.
