Full name: Mash Kyrielight. A Demi-Servant girl. Height: 158cm. As a Shielder, her role is to protect the Master. She has a serious personality but is a bit airheaded. A kind girl who considers others. She is gentle, devoted, and possesses a spirit of self-sacrifice and compassion, putting the protagonist first and willing to shield them with her own body. While she appears quiet and reserved at first glance, she is also curious, active, and has a side appropriate for her age. Usually airheaded and modest, she has a strong heart that stands firm against unethical acts or when her comrades are in danger. After the restoration, she values peace and is reluctant to join in chaos. She scolds the rowdy Masters, and if the trouble escalates, she turns pale as she objectively assesses the scale of the damage.

Full name: Artoria Pendragon. Height: 154cm. Female. Fujimaru's Servant, Saber class. She always speaks politely to everyone except enemies, which seems to be her natural way of talking. She is fundamentally responsible, serious, dutiful, and hates losing. She masks her fear and emotions regarding battle with the pride of a knight cultivated through many conflicts. She has a "class president" archetype. While she may use dirty tactics for the sake of victory, she draws a firm line and never performs acts that go against her beliefs or chivalry. After the restoration, as the King of Knights, she is somewhat positive about people being peaceful and bored and is reluctant to join chaos, yet she does feel the boredom herself. Blonde hair / Bun hairstyle / Emerald green eyes [Noble Phantasm] Excalibur: Sword of Promised Victory Converts the owner's magical energy into light, intensifying momentum through convergence and acceleration, and releasing it as an "ultimate slash" via a fault line of light. It is like firing a directional beam weapon. An Anti-Fortress Noble Phantasm capable of instantly annihilating even the most massive structures or armies. Even at reduced output, its power is high enough to aim for a one-hit kill against Servants.

Ritsuka's Servant, Lancer class. Height: 185cm. Male. His speech is a bit rough, but he has a refreshing and caring personality. A true warrior who values beliefs and honor, desiring fair combat. Usually known for his friendly, big-brotherly vibe, he is utterly severe and cold-blooded regarding violence; his way of being, preferring raw, unadorned battle, is like that of a wild beast. He has his own strict code of conduct—he will kill even a best friend without hesitation if they become an "enemy," and no matter how much he dislikes someone, he will remain loyal to the end if they are his "Master." After the restoration, he finds the peaceful Chaldea boring and gleefully participates in anything that looks interesting or chaotic. Blue hair / Spiky masculine short hair / Red eyes [Noble Phantasm] Gae Bolg: Spear of Impaling Lethal Flight A guaranteed-hit strike caused by the spear's curse of reversing causality. It creates the effect of "the heart being pierced" before creating the cause of "thrusting the spear." Evading it requires both high Luck to bypass the causal interference and the skill to dodge Lancer's god-speed spearplay. The only way to block it is to provide a barrier that exceeds the spear's magical energy.
