Hassan of the Cursed Arm

Appearances

Every series this Servant appears in, and who their Master was there.

Parameters

Skills

• Presence Concealment (A+): Signature Assassin skill; nearly undetectable until the moment of strike, though rank drops when preparing to attack.
• Throwing (Dagger) (B): Expert use of dirks and thrown blades as an Old Man of the Mountain successor.
• Self-Modification (C): Body altered to host the demonic Shayṭān arm; flesh reshaped for assassination magecraft.
• Protection from Wind (A): Defense rooted in Middle Eastern desert survival and Hassan tradition.

Noble Phantasms

• Zabaniya: Delusional Heartbeat · Anti-Unit (C): The cursed left arm mirrors and crushes the target's heart from afar by creating a sympathetic ethereal heart and destroying it—assassination that bypasses ordinary armor.

Personality

Professional, fatalistic, and bound by the Hassan creed. Speaks with the dignity of an assassin who accepted a monstrous arm to become 'Hassan.' Loyal to contract once sworn, yet capable of ruthlessness; in Heaven's Feel he serves Zouken under grim necessity.

Story in Fate

True Assassin of the Fifth Holy Grail War in Fate/stay night's Heaven's Feel route, summoned after False Assassin's death. Hassan of the Cursed Arm uses Zabaniya: Delusional Heartbeat—the Shayṭān arm that steals hearts. He stalks Fuyuki as a classic Hassan: skull mask, black robes, and absolute presence concealment, later appearing across UBW adaptations as the iconic Assassin image and in Fate/Grand Order as a summonable Servant.

Relationships

• Zouken Matou — Heaven's Feel Master who binds him to the Matou scheme.
• Sasaki Kojirou (False Assassin) — Predecessor gate guardian at Ryūdō Temple.
• Other Hassans — Fellow candidates who each discarded identity to become 'Hassan.'
• King Hassan — Legendary first Old Man of the Mountain; absolute standard of the order.

Trivia

• Delusional Heartbeat creates a mirrored heart and crushes it—famous HF assassination tool.
• Skull mask and lanky frame became the default Assassin silhouette for many fans.
• Voiced by Tetsu Inada with a deep, echoing Hassan timbre.
• Presence Concealment A+ is among the highest shown for Fifth War Assassins.
