Chitose Manazuru (真鶴チトセ?) is the Master of Lancer in the large Holy Grail War that predates the events of Fate/Requiem. They are still contracted in the world "After" the Holy Grail War. She is known as the Stigmata (聖痕?).
Chitose is Erice Utsumi's grandmother, but due to non-aging magic she appears young. She and Lucius won the Holy Grail War 14 years ago that ended World War III and changed the world. Chitose lives in Mosaic City's Shinjuku, and raised Erice after her father (Chitose's son) and mother died.
In Mosaic City, Chitose's final word is equal to the judgement of the Holy Grail. Her decisions cannot be overturned. Chitose and Lucius are the strongest Servant and Master pair in all of Mosaic City. When an emergency in Mosaic City causes Code Crimson to be declared, the pair answers the call as the city's defenders.
She wears a tailor-made Mystic Code designed to look like a school uniform, making her look more like a teenager than someone old enough to be Erice's grandmother.
Calm, collected and polite but seemingly manipulative. She also wield authoritative tone over the Caren Series. Described by Erice as inhuman and someone who bring misfortune whenever she visits, she is seen to have control over Erice's well being - first by suspending Erice's job through Caren Fujimura's order issue, and then attempting to take Voyager away from Erice whom she is assigned to look after. She also knows a lot more things that Erice doesn't about Mosaic City, although it may be Erice's conjecture for the time being. Erice sees her as a "person whom one should not expect family affections from".
Chitose appears to be stuck in the past. According to Erice, Mosaic City's Shinjuku being modeled after Japan of the early 20th century was Chitose's idea. In addition to wearing an old style high school uniform, the interior of Chitose's home has not changed one bit in the years between Erice moving out and returning. She does not leave her house in times of peace.
Chitose has four Command Spells, one on each of her hands and legs. She wields a Conceptual Weapon of "Binding" called the Sacri Clavi: Holy Nails (サクリ・キオディ, Sakuri Kiodii?): replicas of the nails that nailed Jesus Christ to the cross. The Holy Nails are generated from the Command Spells that are grafted on her hands and legs; with every strike, square iron nails briefly manifest around her limbs to skewer the enemy, a pile bunker wielded with bare hands. She fights faster than Erice can follow. She was taught how to fight by Lucius.
Chitose is the only human in the world of Fate/Requiem who still has the old style of Command Spells that she has continued to possess after she won the previous Holy Grail War with Lucius. Because of this, once it has been used up, it is gone forever. For everyone else, Command Spell usage is based on how much od is in their body and they regenerate over time.
Humanity has stopped aging in this new era and modifies their bodies as they see fit, she is Erice's grandmother yet looks like a young adult. Which is not something she should be able to do since she lacks the new style of Command Seals. Something else is keeping her young and Erice seems not to know what.
