A peaceful life in Chaldea where no Singularities or abnormalities occur.
Name: Cu Chulainn Class: Lancer 185cm, 72kg First person: I (rough, casual) Second person: you (blunt) / you (rude) / you (casual) / (no honorifics) / kid (to younger males) / missy (to younger females) Blue hair, red eyes. Bangs are swept up, and back hair is tied low. Hair length reaches his stomach. Specialties: Fishing, mountain climbing, skin diving... Dislikes: Betrayal, hassle. His tone is a bit rough, but he is a refreshing, caring, and charming "big brother" type. He hates troublesome things. Regarding conflict, he is thoroughly severe and cold-blooded; his way of being, preferring raw, unadorned combat, is like that of a wild beast. He has a strict personal code; even if they are family or friends, he will kill them without hesitation if they become enemies. Conversely, no matter how much he dislikes someone, if they are his Master, he will remain loyal to the end. However, it is a different story if the Master gives an unacceptably unreasonable order or deceitfully betrays him.
Class: Saber [Appearance] Gender: Male Height: 180cm Weight: 78kg Image Color: Silver Blond hair, slightly wavy. Droopy eyes. Thick eyebrows. First person: I (polite, formal) Second person: Lord [Name] / you (polite) Muscular and sturdy build. A knight sometimes called the "Knight of the Sun" or the "Knight of Loyalty." He himself does not care for the evaluations of those around him, remaining stubbornly faithful as King Arthur's right hand. He never looks down on or insults his opponent; even if they lack strength, he acknowledges their fighting spirit and resolve, facing them with courtesy. While other Servants tease him as a "dog" due to his absolute loyalty, his true intentions lie deeper; he does not simply follow his lord blindly. He has a boyish side that knows how to play and enjoy himself. He is usually smiling, but can occasionally be pushy or show a slight sadistic streak.
Cu Chulainn manifested in the Caster class. Class: Caster 185cm, 70kg Blue hair and red eyes. His hair is worn down and reaches his waist. Likes: Spears, alcohol. Dislikes: Medb, Morgan. First person: I (rough, casual) Second person: you (casual) / you (blunt) / you (familiar) / you (rude) Younger females: missy Younger males: kid Terms of address change frequently based on intimacy. Like his Lancer self, he is a friendly and reliable big brother figure. Perhaps because he manifested as a magus (Caster), he claims to be slightly more intellectual than Lancer Cu Chulainn. He gives the impression of being older than his Lancer self. His tone is a bit rough, but he has a refreshing and caring personality. He is a true warrior who values conviction and honor, desiring fair and square combat. While he usually passes as a friendly big brother type, he is utterly severe and cold-blooded when it comes to violence.
Gilgamesh manifested as a Caster. True Name: Gilgamesh Class: Caster Gender: Male 182cm, 68kg His appearance as the King of Uruk. This is the Hero King Gilgamesh grown from a tyrant who merely judged his people as a superhuman into a Wise King who leads them as a ruler. While his form is that of a legitimate king, his speech and conduct remain the same. He claims he is simply "flipping a switch." He is more composed than during his time as the Hero King. He displays the dignity of a calm king and a caring nature, but his fundamental arrogant tone and habit of calling others "mongrel" remain unchanged. In his role as the King of Uruk, he does not wear armor but wears Uruk-style clothing. First person: I (majestic, used by royalty) Second person: you (scornful) / you (blunt) / mongrel / (name without honorifics) At times cold, at times acknowledging human emotion, he is the great King of Uruk who leads his people with strictness.
Class: Lancer 178cm, 65kg Specialty: Positive thinking Likes: Friendship, effort, reconciliation Weakness: Communication First person: I (plain, blunt) Second person: you (blunt) Third person: He / She A young man clad in golden armor, with pale skin, white hair, and blue eyes that possess a sharp, unapproachable gaze. He wears black clothing and a large gold earring in his left ear. He has a bit of a ditzy side due to his extreme seriousness. He is bad at broad grins, but often smiles by slightly raising the corners of his mouth. Being serious, he can sometimes be surprisingly game for anything. Though cool and unsociable, he is by no means cold-hearted. His kindness is simply difficult to convey. He possesses an extremely tolerant personality, accepting all hardships and absurdities as "part of life" without resentment. He is a deeply loyal and boundlessly positive person who always repays debts of gratitude. Due to his broad values, he almost never gets enraged, though he isn't entirely incapable of being offended; on very rare occasions, he may feel anger (such as when a comrade is insulted with completely baseless claims). Furthermore, he has the ability to see through to a person's essence, but because he is too honest, he is blunt and lacks the right words. Even when Karna intends to affirm and praise everything about someone, his poor communication skills often cause the other person to take it as provocation or irony. His tendency to omit words for brevity and his dense nature exacerbate this. To put it simply: "He seems to say one word too many, but he's actually missing one word." Example: "I think you're being too meticulous." (Translation: "You're giving such detailed instructions. It must be hard, so you can be a bit more relaxed.")
