Due to his Mad Enhancement, Berserker is completely void of thought for most of the story. His emotions have been sealed off, making it impossible to perform any actions with personal motivation, and the only thing not lost is the reason within the core of his being that not even the bondage of the Command Spells can overwhelm. This side is shown in the occasions when he is shown feeling something like the will to protect Ilya. He faces even hopeless fights with his iron will, advancing to keep Ilya from facing death. He can display general thoughts based on his instincts that Ilya can interpret, and she responds as if having a normal conversation. Archer notes that he is one of the Servants completely satisfied with their Master.
Rank up for all parameters, but takes away most of sanity.
