Premise:

When Bazett Fraga McRemitz summons the legendary hero Cu Chulainn as her Lancer Servant, she gets an unexpected surprise: instead of the fierce Irish warrior, Makoto Yuki appears—a young man with blue hair and an inexplicable connection to death itself. With abilities that defy the rules of the Holy Grail War and an aura of mystery that intrigues and unsettles those around him, Makoto must navigate a conflict that was never meant for him… while proving that a legendary hero isn't always needed to be the final protector.

AKA: Leader of S.E.E.S., Messiah, Seal of Nyx, Blue-haired Boy, Wild Card User

False Class: Lancer

Class True: Foreigner

Attribute: Wild Card

Parameters:

Strength - Rank C

Agility - Rank B

Mana - Rank A

Luck - Rank D

These parameters reflect his capability as a warrior but also his limitations as a human assuming a supernatural role, along with his affinity for mysticism and death.

Class Skills

1. Foreign Presence (Foreigner) - Rank B

This skill reflects Makoto's unusual presence in the Holy Grail War, as someone tied to Thanatos, an entity symbolizing death. Other Servants sense Makoto as someone out of place, as if his mere existence threatens the stability of reality. This can provoke fear or distrust in other Servants and may even affect their perceptual abilities when near him.

2. Existence Beyond Heaven - Rank C

Having transcended human death to become the Great Seal containing Nyx, Makoto possesses an existence that doesn't align with ordinary human perception. This skill allows him to resist effects targeting his spiritual existence, making him immune to certain forms of mental manipulation and spiritual control. However, due to his incomplete connection with Nyx, this skill has a relatively low rank.

3. Cosmic Mystery (Thanatos) - Rank B

Thanatos grants Makoto a power that surrounds him as a dark aura, making it difficult for other Servants to approach or attack him without feeling an overwhelming pressure of death. This serves as a shield against weak attacks and a protective barrier against lesser spiritual entities.

Personal Skills:

1. Persona Summoning - Rank A

Makoto can summon and use different Personas from his repertoire to adapt to specific combat situations. Thanatos is his primary and most powerful Persona, but he can also access others with various magical and physical abilities. This skill allows him to vary his attacks and strategies.

2. Survivor's Instinct - Rank B

As someone who has survived countless battles in Tartarus and fought constantly against death, Makoto has a heightened ability to react in extreme danger. This skill allows him to foresee and dodge imminent attacks, similar to other Servants' "Instinct" skill, and is especially useful in intense battles.

3. Death Resistance - Rank A

Due to his connection with Thanatos and his role as the Great Seal, Makoto has a natural resistance to instant death-inducing attacks and curse-based assaults. This makes him particularly resilient to Noble Phantasms that seek to destroy the vital essence or spiritual existence of their target.

Noble Phantasms:

1. Great Seal - Thanatos' Embrace

- Type: Anti-Unit (Anti-World, under certain conditions)

- Rank: A

- Description: The Great Seal represents Makoto's ability to contain Nyx's power and protect humanity from eternal death. When activated, Makoto unleashes a version of Thanatos's power that manifests as a spectral figure, surrounding the area and shielding everything within a set radius.

This barrier acts as a death shield, repelling and neutralizing any attack that attempts to penetrate it. In its active form, Thanatos can launch itself at the enemy, executing an attack that consumes their life force if their spiritual resistance is low enough. However, this move drains Makoto, bringing him closer to being absorbed by Thanatos and risking his spiritual stability.

2. Nyx Avatar - Midnight Embrace

- Type: Anti-World

- Rank: EX (Potential)

- Description: This hidden Noble Phantasm activates only under extreme conditions, such as when Makoto is on the brink of death or humanity's fate is at stake. When "Midnight Embrace" is triggered, Makoto taps into Nyx's power, allowing the deity to manifest and unleash a massive destruction attack. This move carries a tremendous risk, as it threatens to release Nyx and bring Eternal Night to Earth.

Upon activation, Nyx appears in the sky, covering the area in impenetrable darkness. Enemies within this area suffer the "Heart's Gravity" effect, a state that slowly drags them into absolute, irreversible death. However, if Makoto uses this ability, his existence is absorbed by Nyx, resulting in his complete disappearance and ultimate sacrifice.

3. Messiah - Savior's Revelation

- Type: Anti-Unit (Anti-Army under certain conditions)

- Rank: A

- Description: Messiah represents Makoto's willingness to save humanity at any cost, even his own life. By invoking Messiah as a Noble Phantasm, Makoto materializes this Persona, a being of pure light and a symbol of redemption, descending onto the battlefield surrounded by a radiant aura.

Primary Effect: When Messiah manifests, it emits an intense purifying light that acts as spiritual damage against enemies and restores allies' strength. Messiah's presence imposes a state of "Revelation," which attacks the spiritual essence of enemies, weakening their resistance to magic and any curses they carry, while imposing a state of "Spiritual Weight" that hampers their combat abilities. For allies, Messiah replenishes their energy and strengthens their mental resilience, as if easing their emotional and physical burdens, allowing them to fight with renewed vigor.

Secondary Effect: Act of Sacrifice. This is a final move that Messiah can activate if Makoto sacrifices a part of his own essence to protect his allies. This act transforms Messiah into an absolute shield, creating an impenetrable protective barrier around his companions. Upon activation, Messiah's form disintegrates into a barrier around the area, halting any physical, magical, or conceptual attack, including high-ranking Noble Phantasms. While it saves his allies from total damage, Makoto suffers a significant loss of spiritual energy, and excessive use could lead to his disappearance at the end of the battle.

Hidden Effect: Final Judgment. In a desperate situation, if Makoto decides to unleash Messiah's full power, the Noble Phantasm becomes a total annihilation attack affecting both enemies and allies in the area. This is "Final Judgment," a burst of light that erases all malice and exposes everyone present to an absolute purification. This power can be devastating for any corrupt spirit or immoral being within range, and its side effects are unknown, as this move could risk Makoto's life at its completion.

4. Spear of the Final Eclipse

- Type: Anti-Army / Anti-Fortress

- Rank: A

- Description: The Spear of the Final Eclipse is a Noble Phantasm that symbolizes Makoto's role as the boundary between life and death, representing the power of the ultimate eclipse that seals any threat in eternal darkness. The spear itself is crafted from a dark, metallic material that seems to absorb light, with a blade that shifts between deep black and luminous white, reflecting the fate held in Makoto's hands.

- Primary Effect: "Eclipse Zone"

Upon activating this Noble Phantasm, Makoto drives the spear into the ground, creating an Eclipse Zone around him. This zone is a mystical void that cloaks the battlefield in a heavy twilight, slowly draining energy and vitality from any being caught within its radius. Enemies within this zone experience a drop in their parameters, reducing their strength, speed, and endurance as their own life force is sapped and weakened by the spear.

The Eclipse Zone also amplifies Makoto's attacks, boosting the power of both his physical and spiritual abilities, giving him an advantage in prolonged combat. This effect is particularly intense against those with low spiritual resistance, who may even collapse under the crushing weight of the twilight.

- Secondary Effect: "Seal of the Eclipse"

In addition to its draining effects, the Spear of the Final Eclipse can lock an enemy within the zone, preventing them from escaping or using teleportation abilities. Known as the Seal of the Eclipse, this effect causes any enemy caught within the zone to suffer a drastic weakening of their spiritual energy, leaving them exposed to a final strike from Makoto. While those with strong spiritual connections can resist, they are still significantly debilitated.

- Special Condition: "Twilight's End"

In extreme situations, Makoto can unleash the ultimate power of the "Spear of the Final Eclipse", known as "Twilight's End". This attack consumes a vast amount of energy and risks his own essence, manifesting a total eclipse that engulfs everyone present in near-absolute darkness, severing enemies from any external energy or divine protections. In this state, all enemies within the zone are struck by a concentrated wave of death energy, with particularly devastating effects on those with low spiritual resistance or who have already been weakened by the zone. This attack leaves Makoto drained of spiritual energy, making him highly vulnerable after activation.

In my honest opinion... We are cooked
