Alterize McClair

Alterize McClair is the butler of the Einfolk House of the Ymir Theocracy.

Appearance
Alterize has shoulder-length dark hair and wears a formal black dress suit, fitting her job as a butler. She also puts on a coat when in the cold of the Theocracy.

Personality
Alterize is a loyal servant of the Einfolk House and does what she thinks is best for it, even if that means defying the will of individual members of it. For example, she arranges for Krulcifer to have dinner with Balzeride Kreutzer (in preparation for their engagement) without informing the former, despite Krulcifer not wanting to be married yet. However, she is willing to accept her mistakes, as shown when she apologises for introducing Barzeride (after his crimes are revealed) and is prepared to accept punishment.

Alterize is a serious and formal person, speaking to others politely and respectfully (e.g. using the honorific -sama). Possibly because of this, she has little experience with romance and is embarrassed when talking about this topic.

Background
Alterize is an orphan who used to live in an orphanage. She was adopted by the head butler of the Einfolk House and eventually became a butler herself.

Ymir Nobility Arc
Alterize travels to the city of Cross Field to arrange an engagement between Krulcifer and the powerful noble Balzeride Kreutzer. Just before she encounters them, a bandit tries to take her as a hostage, but she easily subdues him. She greets Krulcifer and suggests that they find a more appropriate place to talk.

In a nearby bar, Alterize tries to bring up the planned engagement. However, Krulcifer is currently pretending that Lux is her lover. The situation is further complicated when Balzeride himself appears. After an argument, they decide to settle the dispute with a duel: Krulcifer and Lux versus Alterize and Balzeride. Balzeride agrees and leaves the bar. Alterize scolds Krulcifer for her actions and then also leaves.

When the date of the duel arrives, Alterize and Balzeride face Krulcifer alone (since Lux was exhausted in an unrelated battle and Krulcifer doesn't want him to get involved). Krulcifer puts up a good fight but is at a disadvantage. However, Lux appears wearing Bahamut. Alterize is confused by this since, while she's heard of the story of the Black Hero, it's still a wild story of a foreign country and she can't immediately connect it with Lux. She charges at him, but Lux easily defeats her with his Divine Raiment. Balzeride tells Alterize to leave the duel to him and secretly drains her Drag-Ride's energy to replenish his own. Alterize reluctantly withdraws and, due to the energy drain, faints. While she's unconscious, Lux defeats Balzeride and, when Balzeride tries cheating by calling his private army, the members of the Knight Squadron defeat said army.

Alterize meets with Krulcifer and Lux in a high-class restaurant. She apologises for trying to press the engagement forward while failing to see through Balzeride's scheme. She says that she will be punished on her return to the Einfolk House and asks for forgiveness, which Krulcifer grants. Alterize goes on to say that Lux is a suitable fiance for Krulcifer and she will recommend him to her master. Before Krulcifer and Lux can clear up the misconception, Alterize tells them to enjoy their dinner (which she's already paid for) and leaves.

Abilities
Alterize is a skilled Drag-Knight who pilots an EX Wyrm. She is also skilled at combat outside of her Drag-Ride, being capable of subduing an armed bandit using only her Sword Device.
