Lucianna Leone aka the Nun

Luciana leone is the other main character in the story of TLT. she's known as the nun mostly because Pyotr is always pointing at how monochromatic her outfits are most of the time. she was raised by his uncle, misha and her name is obviously fake but she forgot her real name, so most of the time pyotr, johann and the others calls her "lulu" and she is fine with that.
she's pyotr's twin sister (not identical twins of course) and does barely talk with him. is a good listener and quite an analytic person, also owns a remarkable cold temper, which gives her some advantage at her job towards pyotr.
follows a very strict straight-edge-like way of life and that's one of the main reasons she and pyotr can't stand each other.

next will be johann i guess?
