Not really, we don't have a single follower yet, Maxime is not yet fully our follower, I understand she will become a demon, and get powers, but her powers will depend on how strong the MC is and on how powerful their love, her eye color changed in one sex scene for a while, but that's all, the agreement itself has not yet been reached, MC for now does not have the strength to do it, as his father said. And it is very interesting how Meredith will accept that he is a demon, in the next update she will definitively fall in love completely, and she will probably break up with her husband or even divorce him, but I doubt that a follower agreement will be made with her in the next update, given that Maxime is not yet fully a follower, but may be in the update after the next one. By the way, we don't know the lifespan of demons yet, right? Or did I miss something?
