"One day, we will vanish. New Senshi and new stars will come. But you, Sailor Moon, you will forever be immortal. You will be the most beautiful star shining in the sky for eternity."
— Mamoru Chiba, quote from Act 60 - Stars 11


Mamoru Chiba is the reincarnation of Prince Endymion and Usagi Tsukino's love interest. He is the civilian identity of Tuxedo Mask. This is the original depiction of the manga character created by Naoko Takeuchi.

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".

Apperance

Civilian

Mamoru is a tall man who has dark bluish black hair and deep blue eyes. He is around 5 feet 9 inches in height.

Tuxedo Mask

When Mamoru becomes Tuxedo Mask, he dons a black tuxedo, with yellow buttons and a black cape (lined with red). The jacket is left open to reveal his white dress shirt. He also wears white gloves and a white mask that covers his eyes; at times the mask seems to cover his eyes and other times the mask is merely an outline, leaving his eyes visible. The final touch of his disguise is a black top hat.

Evil Tuxedo Mask

When Mamoru revived is under Galaxia's control, he retains his Tuxedo Mask attire but he wears Galactica Bracelets

Background

Manga

When Mamoru first appears, Usagi, depressed over her bad grade, crumples her test up into a ball and throws it over her shoulder, only for it to accidentally land in his face. He calls her "bump-head" and asks if she is trying to put bumps on his head. She angrily protests that they are dumpling buns, not bumps. He mocks her for only scoring 30 points on the test, and throws the paper back in her face, saying that she needs to study more. Usagi angrily says that he needs to mind his own business, and also notes that he rather strange for wearing a tuxedo in the middle of the days. She calls him a "snobby jerk" and walks away. The man exclaims that OSA-P is a rather large jewelry store, and that it might hold the "Silver Crystal".

Mamoru runs into Usagi again, when she hits him in the face again, this time with a crumbled up ad for the Crystal Seminar School. When he asks if he heard Luna speak, Usagi denies it and runs off. He later continues his research on the Silver Crystal.

Anime

Prior to the Anime

During the Silver Millennium, Mamoru was Prince Endymion of earth. After the Dark Kingdom attacked, he was one of the many to be sent to earth to be reincarnated in the present day by Queen Serenity.

When reawaken, his life was shrouded in mystery, only knowing that his parents died in a car accident.

Sailor Moon

Mamoru first appeared in episode one of the series. After meeting Usagi for the first time, he started calling her "bun head", a nickname he'd call her by every time they met, much to Usagi's annoyance. It was also starting from episode one that he come to help Sailor Moon in battle as Tuxedo Mask.

Mamoru's alter-ego as Tuxedo Mask caught the love of Usagi/Sailor Moon after she saw him for the first time. In fact, Tuxedo Mask was one of Usagi's two main crushes along with Motoki. Although Usagi loved Tuxedo Mask, she didn't like his civilian identity, mainly because Mamoru always called her by the nickname "bun head" that she hated. At the time, she also didn't know who Tuxedo Mask's secret identity was. During season one, Mamoru briefly went out with Rei Hino, though he did not seem as infatuated with her as she was with him.

During season one, Mamoru was also on his own mission to find out who he really was. At night, he would dream about a girl (Queen Serenity) telling him that all will be clear when he finds the Silver Crystal fragments so he begun searching for it, but coincidently, the Dark Kingdom was searching for those same fragments. Mamoru, as Tuxedo Mask, helped the Sailor Senshi to keep the fragments away from the enemy, but he preferred to keep the fragments for himself rather than let the guardians have it.

When the fragments reunited and became the Silver Crystal, it restored his memories, as well as those of the Sailor Senshi. He remembered that he was Prince Endymion of earth who was together with Princess Serenity.

Tuxedo Mask/Mamoru, shortly after regaining his memory, was captured by the Dark Kingdom and brainwashed to do their bidding near the end of the season. He fought against the Sailor Senshis alongside Shitennou Kunzite until the last episode of the season, when Sailor Moon finally turned him good again. After the Sailor Senshi have their final battle against Queen Beryl, he and the Senshi were resurrected, but lost all memories of events in the first season.

Sailor Moon R
Hell Tree Arc

Having lost his memories, Mamoru lived his normal life and unlike the Sailor Senshi, it took much longer for him to regain his memories. However, a part of Mamoru still had a heart for Usagi /Sailor Moon and so split from him and became Moonlight Knight, who took Tuxedo Mask's place.

During the Makaiju arc, Usagi tried to help Mamoru remember who he really was and win his love, but was unsuccessful. Worse for Usagi, a new kid named Ann was also competing for Mamoru.

In episode thirteen of the season, the end of the Makaiju Arc, Moonlight Knight reunited with Mamoru, restoring his memories. Ann, who Mamoru and the Sailor Senshi discovered were actually their enemy in disguise, left earth along with Ail, leaving Mamoru open for Usagi.

Black Moon Arc/Main Story Arc

With his memories restored, he and Usagi officially become a couple and Tuxedo Mask returned, but they soon find their relationship disrupted after the arrival of the Black Moon Clan and Chibiusa. During the Black Moon Arc, Mamoru begun having dreams again much like the previous season. This time, a mysterious voice kept appearing in his dreams, telling him that if he were to be together with her, the world will perish. Mamoru didn't believe at first but soon became troubled. He temporarily broke up with Usagi, but still came to aid her during battle as Tuxedo Mask and hung out with her as normal friends. Usagi was, nevertheless, heartbroken. She thought Chibiusa was the reason for the breakup and once mistaken another girl, Motoki's sister, to be his new girlfriend. Eventually, Usagi did finally come to understand the real reason for the breakup and accepted it and they got back together.

Mamoru's dreams were finally explained after Tuxedo Mask and the Sailor Senshi traveled to 30th Century Crystal Tokyo and met King Endymion. It was revealed that the nightmares were sent by King Endymion, who used the dreams to test the bond between him and Sailor Moon, as their bond would be crucial to defeat the Black Moon Clan.

Mamoru, as Tuxedo Mask, continued battling the Black Moon Clan with the Sailor Senshi until the clan was finally defeated in the second to last episode of the season.

Sailor Moon S

On her birthday, Usagi got disappointed at Mamoru for not knowing what day it was, even though she never even formally told him when her birthday was in the first place. She wanted Mamoru to buy her a pair of glass shoes she liked. Mamoru eventually found out and bought the shoes, which Kaolinite infested with dark energy. The glass shoes turned into a Daimon, which Mamoru tried to defend Usagi from as Tuxedo Mask. Mamoru was temporarily captured but was freed by the Sailor Senshi.

Sailor Moon SuperS

Mamoru becomes very busy for his college thesis throughout the series but still continues to help Usagi on her mission. Near the end of the series, Queen Nehellenia begins to spread spider webs to shroud the earth in darkness, which causes Mamoru to feel pain. As his condition worsens, he was forced to stay behind after it was revealed from Pegasus that his entire body is in pain because he is physically linked to earth. It was also revealed that as Prince Endymion, he was ruler of the Golden Kingdom near Elysion where he entrusted Helios with the Golden Crystal.

Sailor Moon Sailor Stars

In the first arc of the fifth season, when Chibiusa is about to leave for the 30th Century, Mamoru falls victim to the "shooting stars", which are actually glass shards from Queen Nehellenia's broken mirror. He accidentally gets one caught in his right eye, causing him pain. He begins seeing images of Nehellenia. This, along with the pain, causes him to become rather agitated, and even violent. During his date with Usagi in the park, he slaps her hand when she was trying to help him, but apologizes. He become irritated when his computer rings when he is working, and yanks out the keyboard. He remembers what Usagi said, and decides to take a rest.

When the Mirror Paedri attack the Inner Senshi at Hikawa Shrine, Tuxedo Mask appears, only to be afflicted with pain in his eye. After the fight, Usagi and Mamoru walk back to his apartment. Usagi asks if he really is OK, and he assures her that if he rests, he will be better. He then enters his apartment. While washing his face, trying to see whatever is in his eye is out, Mamoru mentions that he feels that his body does not feel like his own. Queen Nehellenia appears to him as an illusion, with her assuring that she will take all that Usagi loves away from her. His right eye glows yellow.

Soon, he is completely entranced by the spell. Like most other people affected, he becomes obsessed with mirrors, constantly looking at them and buying several, refusing to live on with his current life. When Usagi enters his apartment to see if he is alright, she accidently steps on a mirror, and he becomes mad. He then apologizes, saying that he hasn't been himself. Mamoru tells her that he is not well and will get some rest, but soon returns to the mirrors. Soon, the Inner Senshi discover that the illness going around and the mirror are linked, and rush to Mamoru's apartment, learning that he has been affected. After discovering that Nehellenia is behind everything, they burst into the room. Usagi tries to talk to Mamoru and help him, but he slaps her away. Nehellenia reveals herself and drags him with her into the mirror, completely unable to hear Usagi or anyone else.

For the next two episodes, Mamoru is kept in Nehellenia's castle under the curse. Usagi, without her power, desperately rushes to save him, but has to undergo the effects of Nehellenia's curse, and for a short time, forgets about him and her mission to save. When Chibi Moon and Saturn reach Nehellenia's castle, Chibiusa desperately calls out for Mamoru. When it seems to work, Nehellenia heightens her anger and attacks them. When Usagi reaches the castle and suffers the disappearance of Chibiusa and the capture of her friends, she feel sympathy for Nehellenia. Her feelings break her nightmare, freeing Mamoru and everyone else. All use their powers to turn Nehellenia back into a child to start over.

After Nehellenia's defeat, Mamoru soon leaves for Harvard in America. Usagi decides to see him off with a smile, but truly doesn't want him to go. Before getting on the plane he gives her a promise ring and the two kiss. Soon, he is on the plane when suddenly a golden light appears and the plane explodes.

Usagi constantly writes to Mamoru after his departure, only to receive no reply. To cover up her depression and worry so she may not worry her friends, she dons a happy demeanor. She finally breaks in episode 194, when Seiya throws his red rose to stop Tin Nyanko, causing her to remember Mamoru and cries. In episode 197, after the plane bound to America exploded, it reveals that it was actually teleported into Galaxia's domain. Tuxedo Mask then meets and fights against Galaxia, only to have his Star Seed extracted. In his last words, he tells Galaxia that the Sailor Senshi will stop her. He mutters "Usako" before fading away.

Mamoru, along with everyone else, is revived in episode 200 and is reunited with Usagi.

History

When he was six years old, Mamoru's parent's died in a car crash. As the only survivor, he grew up in an orphanage ever since with amnesia.

Season One: Dark Kingdom

When Usagi is upset about her grade on her last English test, she crumbles up the paper and throws it behind her, not realizing Mamoru was standing behind her. He complains to her, while making fun of her hairstyle and throws her test back at her. Usagi begins to complain to him, and they suddenly stare at each other in awe. Mamoru gives Usagi her test back and she walks off, thinking how her heart is beating faster, though outwardly complaining how strange it is that he was wearing a tuxedo in the afternoon. Mamoru then acknowledges the Jewelry store, OSA-P, wondering if it might have the mighty Silver Crystal he is seeking.

Season Two: Black Moon

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 her as "Usagi" and demands that Usagi hand over the Silver Crystal she has in her possession.

Season Three: Death Busters

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 own vital life energy with hers in order to keep her body alive. He soon realized that her body began to grow slightly warmer, as he learned that someone was protecting her spirit.

He noticed Hotaru's spirit outside his window and saw her return the Silver Crystal and Chibiusa's spirit to her. He watched as she Chibiusa and Hotaru had a heartfelt and tearful reunion until she faded away. Tightening his fist, he asked a saddened Chibiusa whether she was ready to help and fight with Sailor Moon. His question, encouraged Chibiusa, who said that she would not cry anymore, that she was a fellow Sailor Guardian. After transforming into Sailor Chibi Moon, she thanked him for looking after her, but now it was her turn to do the same. He transformed into Tuxedo Mask and followed her to fight alongside Sailor Moon the four other Inner and three Outer Guardians.

Personality

Mamoru is a kind and gentle man, being helpful and friendly around others. He also cares a lot about his girlfriend, Usagi; He was always ready to fight by her side, and fought his best to ensure her safety.

Abilties

As a planetary guardian, Mamoru possesses abilities similar to that of a Sailor Senshi. He is able to perform superhuman feats and fire blasts of energy at opponents.

Transformation Phrase?

During one of the mini dramas released along with Act Zero for PGSM, Mamoru was seen transforming with the phrase, "Tuxedo Power." Given the spoof nature of the short, this was likely not meant to be an actual transformation nor transformation phrase. He was seen de-transforming instantaneously in the Special Act, but in Act 7, Motoki returned a repaired tuxedo to Mamoru, leaving the nature of his transformation ambiguous.

Trivia

  • His name 'Mamoru Chiba' is similar to the name "Mamoru Chino," the prototypical name for Makoto Kino.
  • Naoko Takeuchi based his character off of her own ideal of the perfect man.
  • His birthday falls on August 3rd, making him a Leo. The zodiac sign of Leo is ruled by the Sun.
    • The Japanese school year begins around April 1st. Because Mamoru's birthday is August 3rd, he ages to 17 rather early on, however, when he first meets Usagi, he is still 16, while Usagi is confirmed 14 at the start of the series. Usagi's age is confirmed by both Sailor Moon Crystal Episode 2 (Ami's age is displayed to be "14" as well, and she is in the same school year as Usagi) as well as the Sailor Moon Eternal Edition (2019) of the manga.
    • Usagi in comparison ages to 15 by June 30, not long before Mamoru's birthday.
  • Of all the characters, Mamoru gets brainwashed and captured the most throughout the series. Mamoru was kidnapped and brainwashed by the Dark Kingdom and Black Lady. Mamoru is killed then brought back (along with the Sailor Senshi) under the control of Sailor Galaxia.
    • This is to keep the focus on the female protagonists and the importance of them. Showing that not only male characters can save the world and that they also need and can depend on women at some time. Also, probably because of his importance to Usagi.
  • His psychometry was not fully developed until the second season, and was used occasionally throughout the series.
  • Mamoru displays healing abilities without needing to transform into Tuxedo Mask.
  • He is hinted to have a physical relationship with Usagi; he was seen sleeping with her in the last volume of the manga. He is seen sleeping with her once again on the cover of "Sailor Moon Short Stories Volume 2."
  • Mamoru is the character who says the last words of the manga (see quote above).
