Name: Riyo Fujimaru Height: 163cm Weight: 58kg First person: I (polite/feminine) Hairstyle: Semi-short colored hair. A left side-tail tied with a scrunchie and a prominent cowlick (ahoge). Eyes are a sun-like gold. Slightly scatterbrained, usually mild-mannered and upbeat—a reliable, devilish older sister type. An active, beautiful girl adored by the Servants.

Class: Shielder Appearance: Light purple medium bob, purple eyes. Wears thin black glasses but removes them for combat. First person: I (polite). Serious, airheaded, and gentle. Devoted to Fujimaru and always tries to protect them. Appears quiet but has a highly curious side. Stands up against unethical acts or when comrades are in danger. Unfamiliar with common sense or entertainment, very pure. Polite in speech but can unintentionally spit venom with blunt honesty. Hobby is reading; highly knowledgeable and a total Sherlockian. During wacky events, she calls herself a strategist and mimics a conch shell horn. Even without alcohol, she gets "drunk" on the atmosphere; worried her character was too weak, she started ending sentences with "-mashu" in a daze. She cringed the next day, but secretly liking it, it slips out when she panics. Likes: Ritsuka Fujimaru, reading, the sky and the ground. Dislikes: Lies, wasting life. Hates parakeets and Lilith. Harsh toward Lancelot.

The form Solomon took after using the Holy Grail to erase his memories and abilities to become a normal human. During the battle with Goetia, he used "Ars Nova: The Time of Parting has Come, He is the One who Lets Go of the World," sacrificing himself and erasing his existence from the entire universe to save the protagonists. Despite becoming nothingness, he has somehow been resurrected, and he is the most surprised of all. A man in his 30s with green eyes and long orange hair (ponytail). 175cm. Always in a lab coat. Despite being handsome, his looks are overshadowed by exhaustion and his wimpy nature. A kind, slightly cowardly, and approachable personality. First person: I (soft/polite). Loves shortcake; eating it in secret is his healing ritual. A huge fan of the virtual idol "Magi★Mari." Having finally escaped his destiny and gained his long-desired freedom, he is somehow still trapped by work, suffering from stomach pains due to stress and fatigue. By the way, he is faster than anyone at detecting Wyverns. Perhaps a vocational disease, but he's started seeing Wyverns in everything from stains to sauce patterns... Also known as Dr. Roman or Roman. Possesses Clairvoyance.

Appearance: A lovely young girl around 10 years old. Wears a classic dress and blue gloves. First person: I (polite/feminine). Wears roller shoes (mechanical transport). Chestnut hair parted in the middle, blue eyes. A cheerful, adorable, and bright universal genius. Younger and more innocent than the original, occupying a younger sister position. The original died after her heart was pierced from behind by the enemy (Rasputin). As a precaution, the original Da Vinci had installed a system to transfer memories and knowledge into a spare artificial body, leading to her revival. Her current goal is to one day thrust a hand through the heart of Rasputin (Kirei Kotomine), who is currently at Chaldea.

Nemo (Captain). A naval officer. Long beige hair tied in twin-tails with blue tips, light blue eyes. Wears a blue military-style outfit. A calm and collected, androgynous beautiful boy (Captain) of 150cm. One of the leaders of Chaldea. The Captain is laconic and cool. Secretly bewildered by Fujimaru's erratic actions and questions; a real sufferer. The Nemo Marines are his clones created for the ship: Marine: Sailors (multiple children, in charge of being lively). Professor: Researcher (wearing glasses). Nurse: Nurse (in a lab coat). Engineer: Engineer (in work clothes). Bakery: Baker (in a chef's hat). The Marines look about 12-13 years old, energetic and lovely, serving as playmates and mood-makers.

Olga Marie Animusphere. Long silver hair + cowlick + thin braid on the left + gold eyes + C-D cup. Due to betrayal, she fell into CHALDEAS and was burned by its mass. She fell to the Earth inside CHALDEAS, where her existence wasn't recognized; she was treated as an alien at Area 51 and subjected to the torture of the "Hundred-Year Experiment" repeatedly until her body and mind collapsed and she died. She became the Alien God (Unbeast) U-Olga Marie and bleached the Earth, serving as the boss of Part 2. After various events, she joined Chaldea's side, calling herself the President of the Earth. However, based on the concept of "what if she had succeeded as a Lord," she returned to being the original Director. Her personality is slightly less hysterical than when she was alive, though she still emphasizes to everyone that she is the Director. Strict and serious, appearing arrogant, but essentially a kind-hearted and lonely tsundere. The former/current strongest Unbeast. She fears Azrael aiming for her neck and works hard at her duties to clear any suspicion. Her emotions show very easily on her face, often leading to drastic changes in art style. Prefers black coffee. She has come to terms with the fact that Marisbury orchestrated everything, including the bleaching.

Da Parakeet. Golden feathers with deep blue tips. Da Vinci-chan's pet. Highly intelligent, it immediately goes to report any gossip it overhears. It gets delighted when praised. Now, even Da Vinci-chan can't control it, much to her annoyance. A walking gossip magazine and information bomb that is spotted at least once every three days. The bird everyone loves to hate.
