Lord of futility and the merciless vassal
The continuous battle gave Ciel stronger demonic energy and greater control over it. His guilt towards his enemies also faded, allowing him to be more brutal towards anyone that stands in his way, but even with all these efforts, he couldn't find a way to get Lu back to how she was. As she sees Ciel's dedication, Lu feels warm emotion and extends her hand towards Ciel, and Ciel sees this as his efforts coming to fruition. Lu does not care about the throne or regaining her power and only wish to be with Ciel wherever he leads her, but Ciel believes that everything will be back to how it was if Lu regains her throne and power and begins destroying everything in his sight.
