Nomenclature & Etymology[]
Etymology[]
His name, just like the girls', carries a pun. His surname "Chiba" means local and contains the kanji 地 (chi) which also appears in the word "Chikyuu", the Japanese name for Earth and 場 (ba), meaning place or location.
His given name "Mamoru" (衛) means to protect.
So the pun in his name is loosely"Earth Protector", "Local Protector", or simply "Protector of Earth".
Appearance[]
Civilian[]
Mamoru has short neat black hair and deep blue eyes. He usually wears his school uniform and occasionally glasses. Though, he only wears them when reading. He usually has a neutral face, making it hard to tell what he's thinking.
Tuxedo Mask[]
In his Tuxedo Mask form, he wears a top hat with white glasses, a black suit with a cape with red insides, black howard walks, and two gold sun pendants, one on his neck and one at his waist.
Information[]
Mamoru is an only child and lived with his parents until the day of his sixth birthday when all three of them are been involved in a car accident, killing the parents but leaving Mamoru as the sole survivor. However, the incident gives Mamoru retrograde amnesia, leaving him unable to remember anything about his life before the car accident.
He does, however, constantly have dreams about a mysterious girl begging him to find the "Silver Crystal". Believing this Silver Crystal will help him restore his memories, Mamoru adopts the persona "Tuxedo Mask" and seeks out the crystal for himself.
Season One: Dark Kingdom arc[]
When Usagi is upset about her grade on her English test, she crumbles up the paper and throws it behind her, not realizing Mamoru is standing behind her. He complains to her, while making fun of her hairstyle and puts her test back on her face. Usagi begins to complain to him, and they suddenly stare at each other in awe. As Usagi walk away she forgets her bag and quickly takes it back. As she walks off she thinks how her heart is beating faster, though outwardly asking who wears a tuxedo in the afternoon. Mamoru then acknowledges the Jewelry store, OSA-P, wondering if it might have the Legendary Silver Crystal he is seeking.
Season Two: Black Moon arc[]
A few weeks later, Mamoru is enjoying a romantic date with Usagi when his kiss is interrupted by the arrival of a little, pink-haired girl who falls on top of him. He is surprised when the girl introduces herself as "Usagi" and demands that Usagi hand over the Silver Crystal she has in her possession.
Season Three: Infinity arc[]
Mamoru awakes from a vivid dream showing the whole world in utter devastation and destruction, which leaves him greatly concerned. He recalls the shadowy form of a female person holding a long sickle-like weapon and wonders who it could be.
In "Infinite Labyrinth, Part 1", he takes Chibiusa's lifeless form to his apartment and links his vital life energy with hers to keep her body alive. He soon realizes that her body is growing slightly warmer, as he learns that someone is protecting her spirit.
He notices Hotaru's spirit outside his window and sees her return the Silver Crystal and Chibiusa's spirit to her. He watches as Chibiusa and Hotaru have a heartfelt and tearful reunion until she fades away. Tightening his fist, he asks a saddened Chibiusa whether she is ready to help and fight with Sailor Moon. His question encourages Chibiusa, who says that she won’t cry anymore, that she is a Sailor Guardian. After transforming into Sailor Chibi Moon, she thanks him for looking after her, and now it is her turn to do the same. He transforms into Tuxedo Mask and follows her to fight alongside Sailor Moon and the 7 Guardians.
He helps attack Pharaoh 90 with the others but is ineffective. He helps support everyone as Sailor Saturn and Usagi defeat the enemy. After a few months, he along with Chibiusa, Usagi, and Diana go to see Chibiusa off back to the 30th Century. They find a crowd and join them in watching a solar eclipse and just before it begins they hear a strange bell.
Sailor Moon Eternal: Dream arc[]
He witnesses a Pegasus who appears before them looking for a maiden with beautiful dreams. The Pegasus disappears quickly and then they watch the eclipse and see a strange ship and hear the "Dead Moon Circus" announce themselves. Finding the crowd too large for Chibiusa to head home, he goes shopping with the girls and buys then kaleidoscopes. They sleep over at Mamoru's Home and he has an odd dream of Chibiusa with the Pegasus. He wakes up in the morning to find a note from Chibiusa explaining she will be heading back to the Crystal Palace on her own.
He and Usagi arrive at the park to find Chibiusa and Diana unable to return to the future and the Pegasus asking for help. To investigate the strange occurrences, they head to the command center under Game Center Crown and meet with Luna and Artemis. While there, a news report declares an emergency as a Tiger is running free in Azabu-Juban and Usagi and Chibiusa run out to help. When Mamoru catches up to them he sees their kaleidoscopes are now weapons and recognizes the name Helios and faints.
He awakens in the hospital with the girls oddly having swapped ages. Ami's Mother is his doctor and he feels like he cannot breath with something in his chest. His X-ray shows a black spot on his lungs and he goes back home and rests while hiding his affliction from Usagi. He joins the Guardians to visit the Dead Moon Circus to investigate and spends time with Chibiusa and Usagi. As the Guardians continue to engage the Dead Moon Circus, Mamoru becomes bedridden and begins to cough up blood. When Usagi comes to give him supplies he tells her to leave so he can rest to prevent her from seeing his affliction. Usagi later sends Chibiusa to check on him worried he'll send her away again and she gifts him a ring she is given.
The ring summons Lemures which attack him and Pegasus comes to protect him. Eventually, Super Sailor Moon, Super Sailor Chibi Moon, and Super Sailor Jupiter arrive and stop the attack. The girls see Mamoru coughing up blood and Helios, then takes a humanoid form and explains how the affliction is a black rose which passed from him to Mamoru due to the curse on Elysion through their connection. Helios is his Guardian Priest and they are both connected to the Earth and Elysion. He describes the Dead Moon and begs them to find the Golden Crystal to stop the enemy.
Usagi spends time with him and becomes cursed herself. When the Outer Sailor Guardians arrive at the circus he along with everyone else arrive at the circus. Zirconia uses the curse to shrink him and Usagi into children to kill them. Helios appears and teleports them to Elysion to save them and undoing the de-aging. There, they head to the shrine where Mamoru recognizes it. Helios explains that Elysion is the Golden Kingdom where Prince Endymion resided before heading to the Earth's surface. Helios explains that Prince Endymion wielded the Golden Crystal and Princess Serenity the Silver Crystal and together protected the Earth but he doesn't know where the Golden Crystal is. Usagi; however, is confident it is sealed within Mamoru like the Silver Crystal was within her and he has been using it to give her strength all along and that they will continue to protect the Earth together. Helios sends them back to the surface as Queen Nehelenia takes notice of their presence.
At the surface, Zirconia amps up the heat on the Earth and everyone begins to faint. Helios sends the purifying crystals that saved them earlier to the Earth's surface and Mamoru feels Helios lose the last of his strength. Mamoru wakes up everyone else from a nightmare and they defeat the enemy and eventually chase them back to Elysion. There he meets the Maenads and see the passed out Helios. Queen Nehelenia arrives and traps them all in a kaledioscope where she shows them a vision of the Silver Millennium before stealing the Silver Crystal and prepares to end everyone. Mamoru refuses to give up and he and Usagi kiss and break out of the spell.
Usagi calls forth her Holy Moon Chalice for the first time and the Sailor Power Guardians appear and instruct the Guardians to send power from their castles. This lets Usagi become Eternal Sailor Moon and she calls for power to be sent to her Eternal Tiare. The Guardians offer power from their Sailor Crystals, take their Eternal Forms, and Mamoru awakens his Golden Crystal. Eternal Sailor Moon uses Starlight Honeymoon Therapy Kiss to finish their enemy and ends the curse of the Dead Moon.
This returns the beauty to Elysion. Chibiusa revives Helios and he meets with Mamoru and Usagi. Mamoru hands him the Golden Crystal which Helios fixes to a staff. Once Mamoru takes the staff, he takes a form strongly resembling his future self King Endymion and Usagi looks like Neo-Queen Serenity. Everyone else watches the coronation of the two monarchs as they clean up what's left of Nehelenia's mirror.
He watches the Sailor Quartet awaken and swear to protect Chibiusa in the future before they head back to sleep. Helios escorts everyone back to the surface with the others and sees them off. Mamoru feels a heat in his chest and Usagi tells him that it’s shining strong.
Sailor Moon Cosmos: Stars arc[]
Powers[]
Mamoru is capable of healing without needing to transform. He is also capable of having premonitions of impending danger. Mamoru shares a strong telepathic connection with Usagi. With some effort, he can directly communicate with her without a communication device. When Chibiusa loses her soul to Mistress 9, her heart stops beating and Mamoru links his vital energy with her to keep her body alive until her spirit is returned.

Trivia[]
- The Settei notes for Season 1 includes a Dark Kingdom arc height chart which lists Mamoru as 190 cm. The Season 3 Settei height chart has him at 180 cm implying he shrunk. The same charts list Sailor Moon (with heels) as 155 cm in both implying she didn't grow at all. He is taller than all of the Solar System Guardians but the comparison suggests the values are only approximate.
