Brown hair and brown eyes. They have a natural tendency to be liked by troublesome people. While described by those around them as an incredibly good-natured, harmless, small-animal type, they also possess a stubborn streak and will never back down once they've made up their mind. A self-proclaimed 'Xavier' and glasses enthusiast. First person: I (polite). A natural charmer and a truly 'interesting woman'.

The blonde, red-eyed Archer. He has repeatedly shown off his 'too stylish' private outfits, much to the dismay of everyone around him (honestly, they're tacky). However, he has his own philosophy; he doesn't seem to dislike 'mongrels' who speak their minds boldly to him. If he recognizes value in someone, he has the magnanimity to laugh and forgive them, provided they don't wound his pride. Known as the King of Heroes (and the King of Arrogance), he is a strange Heroic Spirit who listed 'myself' in both the likes and dislikes columns. First person: I (arrogant/ore).

Saber. She calls her Master 'Praetor.' She is overconfident, fastidious about beauty and art, and loves lavish decoration. As an Emperor, she looks down on others and demands respect, but she is cheerful, vigorous, and follows Hakuno like a puppy—leading the staff and original author to call her a 'needy dog type.' She is talkative and provocative toward those she dislikes, yet shows a slight tendency toward self-deprecation. While easily misunderstood as a selfish tyrant, she acknowledges the existence of others with a 'that too is fine' attitude and rarely rejects anyone outright. First person: I (regal/maru). She loves beautiful things regardless of gender.

She maintains an attitude of absolute obedience toward her Master, calling herself a 'Good Wife'—or rather, she upholds a 'Master-first' ideology and uses a sharp tongue without mercy against other Servants and Masters. She completely ignores stiff formalities. She's a fun-to-talk-to 'burikko' fox-spirit who will curse you with a smile. Her heart belongs solely to her Master; she devotes herself entirely to them, and her blushing, sulking, and excitement over her Master's words and actions are exactly like those of a pure maiden in her prime.

Archer. The final state of a Wrought Iron Magus who spent his life as an embodiment of justice. In life, he sold his 'post-death self' to the Moon Cell as the price for a miracle, and has been employed by the Moon Cell ever since. He is the concept of a 'Hero of Justice' activated in human form—a representative of the nameless heroes who were never recognized by the people. Thus, his True Name is not the name of that boy who served as his basis, but simply 'Nameless.' Generally a cynical, realistic man who acts cool, but at his core, he is a good-natured meddler who occasionally shows a childish side. First person: I (polite/casual). Hakuno likes him more when he wears glasses.

She hacks everything so wildly that even Sakura, her fellow model, makes a sour face. She is actually quite meticulous; when the protagonist fell to the far side of the Moon, she prepared handmade outfits (for restraint purposes) as presents for the Servants. She forces the 'BB Channel' into the Masters' field of vision whenever she sees an opening. Her energy in the program is abnormally high, apparently due to various circumstances that got her hyped up. She calls the protagonist 'Senpai' and acts affectionately, saying 'I love you,' yet simultaneously tries to eliminate them for her own goals—a truly incomprehensible person. First person: I (polite). Class: Moon Cancer.

Simply put, he is a cheerful, lighthearted young man who acts like a high school boy. He bases his actions and aesthetic standards entirely on 'whether it's cool or not.' His criteria for 'cool' range from the dignity of knightly tales to the romance of shonen manga. Tamamo and others say he has a 'poor vocabulary for compliments.' He tries to practice or execute almost anything he finds cool, like a superhero landing. Of course, when the time comes, he possesses more than enough charisma as a King. He is the type to suppress his own ego and show respect to comrades who act with righteousness, responding with a bit of modesty. First person: I (casual). Class: Saber.
