Jien

Jien is the older half-sister of Syuen, the current CEO of Missilis Industry and the Illegitimate daughter of the former CEO of Missilis Industry, Enme. Jien was originally a candidate to become the CEO of Missilis, but her father, knowing the monster she truly would become, he sent her to M.M.R. to be locked up in its deep underground facility. However, Jien would become a top researcher in M.M.R. and gave up on the title of CEO and now only focus on her own personal research while having no attachment towards anyone and only seeing every living creature as a test subject.
