Scilla, member of the [ ] team of the Western Branch in the Central Capital. Despite having no ties to anyone in the Western Branch Scilla remains an important part of his team and has had the chance of carrying out emergency expeditions in the outskirts of ravaged towns.

Scilla suffers of amnesia and a strange infection, the latter a side effect of being exposed to unknown chemicals, moreover the only memory she holds on to is a simple and plain ring but she doesn't appear to look for traces of her past and his status seems to be more than enough at the moment.

Rough expeditions and rescue attempts have led Scilla into contaminated territory and therefore ending in her disappearance during the latest assault on the Eastern Branch.
