Jien

Jien is one of the researchers for Missilis Industry's M.M.R., a complex research institution. She is also the half-sister to Syuen. Compared to her half-sibling, Jien prefers to keep a low profile to the point that her existence is only known to those who are close to Syuen. Much like Ether, Jien refers to the Protagonist as "No. 7," and shows a keen interest to the charismatic commander. Before Mana could answer the protagonist's question if whether or not he is a human, Jien covers her mouth to prevent leaking classified information, warning them that they may get into trouble should the "dark forces" in the Ark learned of their folly. Mana briefly thanked her in relief. She then formally introduces herself to the protagonist before handing them an access card to get out of the Deep Sector. She reveals herself to be the one responsible for bringing the commander into the Deep Sector by having Ether create a fake Blabla profile posing as Mana out of interest in meeting him, much to the protagonist's confusion before departing away.
