• True Name: The Grim Reaper (Composite Divine Spirit of Pale Rider & Ereshkigal / Ningishzida)

• Vessel: Misaya Reiroukan (Custom Homunculus)

• Class: Avenger

Refined Backstory

In this warped timeline, the collective cultural, mythic, and divine concepts of absolute death—anchored by the Biblical prophecy of the Pale Rider and the ancient underworld authority of Kur—were synthesized into a single, supreme embodiment: The Grim Reaper.

Because a purely conceptual entity of such magnitude cannot manifest as a standard Servant without a physical anchor, the Reiroukan family engineered Misaya as a specialized, high-capacity homunculus vessel. When user completed the ritual using the two ancient catalysts, the Grail bound the entirety of the Grim Reaper concept straight into Misaya's customized Magic Circuits. Her deep-seated resentment toward the Grail's tragic design, combined with her fierce bond with user, warped her Saint Graph—awakening her not as a passive harbinger, but as a vengeful Avenger.

Weapon: Harvest of Kur (Red & Black Scythe)

Her weapon manifests as a massive, obsidian-black scythe forged from the condensed bone-iron of the Underworld and infused with the viral, decaying aura of the Pale Rider. The inner edge of the blade glows with a pulsing, crimson light that matches her eyes, leaving trails of red lightning and black smoke whenever she swings it.

• Soul-Reaping Edge: The scythe does not merely inflict physical wounds; it directly severs Magic Circuits and harvests residual mana from whatever it strikes.

• Range Alteration: Misaya can extend the scythe's reach by projecting the blade out as a crimson wave of pure, condensed plague energy, slicing through defenses from a distance.

Expanded Class & Personal Skills

Class Skills

• Avenger EX: Converts ambient hatred, curses, and battle damage directly into her own mana output. Her strength continually scales the longer a fight drags on, fueled by the grudges of the Underworld.

• Oblivion Correction A: Attacks delivered by her scythe retain the eternal, unforgiving nature of the Underworld. Critical strikes bypass normal magic defenses and target the opponent's spiritual core directly.

• Self-Replenishment (Mana) A+: Her mana continuously surges as long as her desire to protect Josh remains absolute. She can operate at high efficiency with minimal strain on Josh's personal reserves.

Personal Skills

• Flirtatious Underworld Authority A: A fusion of Misaya's natural teasing charm and Ereshkigal's Divine authority. She can charm, distract, or disorient opposing Servants and Masters while subtly draining their mana through eye contact or physical proximity.

• Naïve Pestilence EX: Derived from the Pale Rider, this skill unleashes a passive aura of decay whenever she feels flustered, threatened, or overly defensive. Because of her simplistic, literal understanding of mortal fragility, she often forgets how lethal it is and relies on Josh to remind her to dial it back.

• Homunculus Frame (Reaper) A+: Misaya's custom-built body acts as the ultimate stabilizer for her Composite Spirit. Her skeletal ribcage armor and internal Magic Circuits rapidly repair physical damage using hardened bone-lattice structures, allowing her to tank heavy hits without breaking.
