Arche is a tier 3 magic caster who is the elder sister to Ureirika and Kuuderika and the oldest daughter of the former noble Furt Family. She's a member of team Foresight consisting of other workers Imina and Roberdyck Goltron lead by Hekkeran Termite. Following the emperor’s purge, she left the academy, much to Fluder Paradyne's disappointment. With no other options, she was forced to become a worker taking up illegal jobs to repay her family's constant debt. She later then joined Foresight.
