Shadow's Samsara

Shadow's Samsara (影の輪廻, Kage no Rinne) are an organization comprised of six individuals, including its leader Emilia Plater, who devote themselves to extinguishing. While acting formally under the alias of a Guild, they don't actually function as such: also, they strangely have the approval of the Magic Council to fulfill their actions.

Overview
Little of the group's history is truly known, due to their very reclusive nature. However, Emilia appeared to have formed the group ever since she was a young teenager, starting it with Liam Archibald as children as a vigilante group against a local. Ever since their successful skirmish against them, the confidence of Emilia and Liam grew, and they began to travel to other localities to deliver these very results. During these visits, they would visit a younger Donna Houdini who had recently run away from her home, and joined them because she believed she would gain an identity. Three years later, on a mission where Sōken Ryōen, Blake Nogami and Angelica Calendula were doing the same job as the trio, they would team up and eventually form the current Samsara that is present. While many of their recent encounters aren't known, they appeared to be vital in taking down.
