Jien was first mentioned during Wordless, the side story which show us Yuni as a chimera, a fusion between a Nikke and Raptures parts

Jien then appeared in Wisdom Spring, she wanted to "see us" for the first time for reasons...

And lastly, she appeared in Unbreakable Sphere, to give Mihara her "D.E.E.P upgrade" by fusing her core and a rapture core. There's a reason why, even in gameplay, a nikke's core gets stronger when you feed them rapture core dust

Jien is not part of D.E.E.P but she's clearly following their goals. She's always present when the whole "fusion" plot is being developed

Also a funny thing, both Jien and Syuen (and even Ether) have a subtle focus on the purple color, is it related to DEEP? (as in deep purple? o_O? ) >>717886990
