Personality

Ritsuka is candid, compassionate, and determined. Although she openly admits fear when confronted with mythical enemies and disasters, she refuses to abandon the people depending on her. Her resolve is rooted in protecting others and continuing forward with her companions rather than in a desire for personal power. 180 181

She instinctively forms connections with people others find difficult to approach. Her understanding of Ereshkigal’s loneliness allows her to turn a hostile encounter into an alliance, while her first wishes before the Greater Grail concern Mash, Chaldea’s staff, and those injured in the war. 181 217

Despite receiving extraordinary power, Ritsuka remains uncertain about combat and reluctant to use destructive abilities carelessly. She considers herself an ordinary person with no prior fighting experience and relies heavily on allies, Command Spells, and Chaldea’s support. 209 218

Abilities & Skills

Master of Chaldea

Ritsuka commands Servants through Chaldea’s Master system and directs allies toward the primary objective during large-scale battles.

• Used a Command Spell to restore Ushiwakamaru’s strength after the Servant burned her Saint Graph. 209
• Formed a new Master–Servant contract with Artoria after Emiya Kiritsugu’s death. 175
• Directly supplies Ereshkigal with enough magical energy to undertake the relocation of the Underworld. 218
• Prioritizes Tiamat as the central threat and orders the group to bypass the evolving Lahmu. 219

Inherited Power

The Greater Grail transfers a portion of Uchiha Yuji’s power and knowledge into Ritsuka, dramatically increasing her physical ability and magical-energy output. 181 182

• Can wield a divine axe vastly larger than herself without visible strain. 214
• Possesses enough strength to shock Quetzalcoatl, Merlin, Mash, and other Servants. 214
• Her enhanced magical-energy supply improves the parameters of Servants under her command. 218
• The initial transfer overwhelms her body and causes her to faint. 182
• She remains inexperienced with fighting and is hesitant to activate power she considers excessively dangerous. 209

Command Spells

Ritsuka uses Command Spells decisively to protect allies rather than compel them against their will.

• Ordered Artoria to destroy Bluebeard when his ritual threatened Fuyuki. 176
• Restored Ushiwakamaru’s strength during the battle against Gorgon. 209
• Her Command Spell system normally provides three spells per Singularity and cannot usually be replenished within that Singularity. 209

Teleportation

Ritsuka has learned a limited teleportation method from Uchiha Yuji.

• Uses Chaldea’s coordinate lock while providing the magical energy herself. 218
• States that she is not skilled with delicate techniques, including this ability. 218

Diplomacy and Bond-Building

Ritsuka’s greatest natural strength is her ability to understand others and make them allies.

• Recognizes that Ereshkigal, rather than Ishtar, had been speaking with her at night. 217
• Identifies Ereshkigal’s protective work in the Underworld and convinces her to join the effort against Tiamat. 217
• Earns Quetzalcoatl’s admiration and an offer to teach her wrestling. 214
• Treats Servants as companions rather than expendable tools. 181 217

Equipment / Weapons / Items

• Chaldea Mystic Code — protective equipment issued by Chaldea. 176
• Command Spells — used to empower and direct Servants. 176 209
• Colossal divine axe — wielded through her enhanced physical strength during the confrontation with Quetzalcoatl. 214

Relationships

• Mash Kyrielight — Ritsuka’s closest companion and protector; Ritsuka wishes for Mash to have a healthy body, while Mash repeatedly shields and worries for her. 173 181
• Uchiha Yuji — mentor-like “senpai” and benefactor who recognizes her as humanity’s savior, transfers power to her through the Greater Grail, and answers her call for aid across worlds. 152 181 182 208
• Romani Archaman — Chaldea companion who explains the Singularity and warns Ritsuka about dangers such as the Greater Grail’s black mud. 152 178
• Artoria — Servant who becomes Ritsuka’s Servant after Kiritsugu’s death; Ritsuka later uses a Command Spell in concert with Artoria’s own will against Bluebeard. 175 176
• Ereshkigal — ruler of the Underworld whom Ritsuka befriends and recruits to oppose Tiamat; Ereshkigal directly serves under her afterward. 217 218
• Quetzalcoatl — impressed by Ritsuka’s physical strength and offers to teach her wrestling. 214
• Ushiwakamaru — loyal Servant whose depleted strength Ritsuka restores with a Command Spell. 209
• Gilgamesh — an ally in the Mesopotamian Singularity with whom she shares a blunt, familiar rapport. 215 216

Story Role / Major Arcs

Fourth Holy Grail War Singularity

Ritsuka arrives with Romani Archaman to investigate an abnormal Holy Grail War containing fifteen Master–Servant pairs and a corrupted Greater Grail. Uchiha Yuji immediately recognizes her reputation as humanity’s last Master. 152 153

During the conflict with Kiara Sessyoin, Ritsuka calls on Yuji for help, reacts quickly when Artoria is forced to attack by Command Spells, and remains focused on protecting Mash and their allies. 173

After the Greater Grail’s manifestation threatens Fuyuki, she withstands the chaos without touching the corruptive black mud. Yuji restores enough energy for the Grail to grant wishes, and Ritsuka asks first for the safety and happiness of others before requesting strength to fight beside her companions and defeat the Mage King. 178 181

The Greater Grail transfers Yuji’s power to her, then shatters. Mash and Ritsuka are extracted from the collapsing cavern by Chaldea’s Spiritron Transfer. 182

Mesopotamian Singularity

Facing Gorgon’s assault on Uruk, Ritsuka summons Yuji across worlds for help and uses a Command Spell to preserve Ushiwakamaru after her Saint Graph is damaged. 208 209

After Yuji takes responsibility for Tiamat, Ritsuka accepts the task of confronting the remaining goddesses. Her inherited strength becomes apparent when she wields a colossal divine axe and astonishes Quetzalcoatl. 210 214

Ritsuka leads the group into the Underworld, recognizes Ereshkigal’s true identity and protective nature, and convinces her to join the effort against Tiamat. With Ritsuka’s magical-energy supply, Ereshkigal prepares to move the Underworld beneath Uruk. 215 217 218
