Xavier is the first love interest introduced inLove And Deepspace. From the moment he enters the story, Xavier gives off a secretive, mysterious air. Despite being the best Hunter in UNICORNS, little else is known about him. Perhaps not even by Captain Jenna or his other colleagues.
But to the MC, Xavier is a soft-spoken and formidable partner who she can always rely on. The two form a powerful duo, with Xavier’s light Evol supporting her resonance Evol perfectly. However, no matter how close the MC and Xavier get during the main story, there’s still much she doesn’t know about him.
This article contains spoilers for the main story and many of Xavier’s memory cards.
Who Is Xavier?
Xavier is the MC’sHunter partner in UNICORNS,as well as herupstairs neighbor. He’s thebest Hunterin the Association and his work hunting Wanderers in the No-Hunt Zones hassaved countless lives.
While Xavier currently lives in Linkon, he wasoriginally born on Philos, a planet on the other side of theDeepspace Tunnel. Additionally, Xavier is atime travelerwho has traveled to Linkon fromhundreds of yearsin the future.
Due to the complicated nature of time travel, no one is sure how old Xavier is, but based on the few dates mentioned in the story and the fact that he comes from an eternal race of humans, he could very well beseveral hundred years old.
While his age is unknown,his birthday is not. Xavier was born onOctober 16th, making him aLibra.
He issix feet one inch tall(185.42 cm) with ash-blond hair and a soft complexion. Xavier’sgentle appearanceand soft face contrast with his intimidating aura.
Xavier also possesses abilities unique even among Evolvers. His Evol isLight manipulation, one of the strongest Evols recorded. He is alsoable to teleportover long distances andmove fasterthan the average person.
Xavier is also anexperienced swordsmanand wields the fabledLightblade,a sword that has been passed down through generations of royalty on Philos.
Personality
Xavier’s personality is a bit enigmatic, but he’s generally considereddifficult to approachdespite his gentle appearance. He’ssoft-spokenwhen conversing with his friends or the MC, but hisvoice deepensmenacingly when inbattleor talking to someone he considers anadversary.
In a text message with the MC during theFestive Blessing Event, his fellow Hunters even believed he was going to spend the holiday alone simply because of how closed off and intimidating he seems.
Most people are intimidated by Xavier’s quiet nature andmysterious outings.He often leaves his apartment in the middle of the night,using the window to teleportaway rather than leaving through the front door.
In another text message with the MC about a mandatory building meeting, the MC tells him thattheir neighbors even believe Xavier is mixed up in shady dealings,simply because of his odd hours and habits.
Xavier oftensleeps through the dayor at unusual locations and times. He canfall asleep just about anywhere, including standing up. This is quite alarming to people who don’t know him.
Yet, despite his confusing sleeping habits and contradictory appearance, Xavier is aformidable hunterand the best one in UNICORNS. It’s common knowledge in the Association that Xavier isnot a man to be messed withor taken lightly. HisEvol and sword skillsmake him aconsiderable threatto anyone who opposes him.
Xavier also has a bit of adark sidethat deters others from getting close to him. This is particularly obvious when it comes to his relationship with the MC. Xavier is quite possessive of the MCand jealous when she gives attention to or receives attention from others,particularly men.
Xavier’s jealous behavior is showcased inChapter 8, Episode 5, Philo, as well as in hisNightly Rendezvous memory card, Xavier: Misty Silhouette.
Xavier’s possessive streak haseven driven him to murderon behalf of the MC. In the main story, members of theBacktrackers(the time travelers he came to Linkon with) who try to threaten her safety areswiftly and secretly executed. The MC isunawareof these encounters.
Work Life
Xavier works as aHunter at the Hunter Associationin Linkon. He is a member of the special forces group,UNICORNS, and the MC’s hunter partner.
He is also aTenebra, though it’s unclear if anyone within the Association knows that he hasbroken the Hunter’s Code. As part of his Tenebra activities, Xavierhunts bountiesposted inthe Nestand turns in the Protocores he gets from them. However,he never takes paymentfor these bounties.
Xavier’s Past
Back on Philos,Xavier was a crown prince, set to inherit his father’s throne. However, after coming to Linkon via theDeepspace Tunnel, his title holds little sway over anyone but the small crew he traveled back in time with.
On Philos, Xavier wasin love with another incarnationof the MC. To save her from anendless cycle of death and resurrection, Xavier traveled back in time searching for a cure or an alternative for the energy source her heart provides.
Lumiere
When the MC was a child, the research facility she lived in wasdestroyed during the Chronorift Catastrophe.All around her was destruction at the hands ofWanderers, who newly appeared from the Deepspace Tunnel.
Terrified, she tried to survive the brutal battle zone that had once been her home. All of a sudden, aglowing presenceappeared on the field — it was themasked Hunter, Lumiere. He stepped onto the field and became thefirst person ever to kill a Wanderer.
Lumiere’s intervention ultimatelysaved the MCfrom the Wanderer, Tezcatlipoca. After the Chronorift Catastrophe, Lumiere quickly became thebest Hunterin the Association. However, very little was ever known about him. He isassumed to be in his fortiesby the time the main story starts, but no one truly knows his age.
The truth, however, is right in front of the MC’s eyes.Lumiere is Xavier. While she doesn’t quite understand how the timing would add up, the MC begins to suspect the truth that Xavier is thesame Lumierewho hadsaved her and countless othersduring the Chronorift Catastrophe.
At the end of the Prologue, Xavier enters The Nest, bringing Protocore fragments in as bounties. This is proof not only that he is Lumiere, but thathe is also a Tenebrawho participates in illegal Protocore transactions.
While the MC can’t yet prove that Xavier is Lumiere, she does know a bit about the legendary hero. Lumiere is now a Tenebra, arogue Hunterwho broke the Hunter’s Code. Tenebrae areknown to smuggle Protocores, endanger civilians, and join criminal organizations likeOnychinus.
The Backtrackers
The Backtrackers are the group ofLightseeker Knightsthat Xavier brought with himfrom Philos to Earth. They took their spaceship, Traceback II, through the Deepspace Tunnel to find a way tosave not only Philos, but the MC,who is now the planet’s queen.
The Backtracker’s initial mission was tohead back in timeto find a way to save the people of Philos. What the Backtrackers did not realize is that by heading back in time tostop the endless cycleof the MC’s death and rebirth at the center of the planet, they wereslowly erasing the Philos of the future.
Each one of the Backtrackers isslowly fading away. They lose their memories, are forgotten by those around them, andsome even become Wanderers.
Because of their new predicament,factions have broken outwithin the Backtrackers. Some think ofXavier as a traitorfor bringing them here ultimately toerase them all. Othersshare Xavier’s valuesand believe that it is wrong to sacrifice even one soul for the life of the planet.
Some Backtrackers believe that their mission is tosave themselves, while others believe that their mission is toprotect their loved ones.For Xavier,only one soul mattersand that is the soul of his beloved, the MC.

Xavier’s Myth - Shooting Stars
Xavier’s myth begins with him holding a secret meeting with the new’crownless' queen of Philos— anincarnation of the MC.Xavier, herGrandis Knight,is preparing to leave on a mission with the Backtrackers to go back in time. The MC, knowing that Xavier’s mission must remain a secret,pronounces him deadto the kingdom.
After the MC tells Xavier she will announce his valiant sacrifice, she realizes that Xavierhasn’t called her by her namefor many long years. Nostalgic, shegazes at the star tasselon his sword. She then begins to reminisce about their time at Astria Knyght Academy.
In theMC’s flashbackto their time at the Academy, she eagerly awaits thereturn of the crown prince, Xavier, from a Starhunters space expedition. She approachesJeremiah, the vice-captainof the Starhunters expedition, and asks him where the crown prince, Xavier is.
Jeremiah covers for Xavier,trying to distract the MCfrom going to find him up at his secret spot atop the academy’s clock tower. The star-shaped sword tassel reappears, and the MC notices that Xavier isstaring longingly at it.
Starhuntersare knights who specialize in theStrengthe swordsmanship style. Xavier is theprefectof the Starhunters, whilethe MCis theprefectof theMoonchasers,a house in the Academy who specializes in theSupporto swordsmanship style.
The MC recalls that several months ago,Xavier had disappeareddespite the Academy’s insistence that all students declare their whereabouts due toincreased Wanderer activity. It’s during that curfew that Xavier boards the Starhunter expedition and flees for the stars without a word to his family.
The MC hadcovered for him, refusing to tell his family where he had gone.
She asks him about thetasselon his sword, but Xavierdodges each of her questions. Instead of telling her who gave him the tassel, Xavier asks the MC to do him a favor andmeet at noonthe next day.
Xavier and the MC train at Astria Knyght Academy to becomeLightseekers, special knights who answer directly to the royal family. In the myth, Xavier tells the MC that the Lightseekers are currentlyonly looking to add oneperson to their ranks.
Xavier and the MCpretend that they are enemy prefectsand rivals for the last Lightseeker position. The pairstage a duelin the square and Xavier rigs it so that the MC will win.
During the setup for their duel, Xavier reveals that he isintentionally losing his battlesso that he doesn’t have to return home to the royal family and his father, whom he has a tense relationship with. He even goes so far as to sayhe wishes the king was not his father at all.
When it seems he could be injured by the MC’s strike, theroyal guards break up their dueland drag Xavier away. However, it is the MC who ends up injured, nursing a sprained ankle in the aftermath of the fight. Jeremiah finds her and explains that Xavier is upset because the royal family isdiscussing arranging his marriage.
Both Xavier and the MCsharea swordsmanship instructor. The MC is being trained specifically to become theGrandis Knight,the crown prince’sprotector.However, Xavier admits that he’sunsure if he will ever sit on the throne, as he has no desire to.
The idea of the MC being the Grandis Knight to someone who isn’t him disturbs Xavier. Hedoesn’t want her to swear fealtyto anyone but him. He plans to refuse the crown and asks that shegive up on joining the Lightseekers.
Instead, he asks her torun away with him to Uluru, a newborn planet he discovered on his last expedition. He tells her that should he successfully avoid being crowned king and should shegive up on being Grandis Knight, he wants toelopewith her to Uluru.
In another flashback, the MC recalls one of Xavier’s many trials as the future king. His father had sent him into Starfall Forest for theGladius Ceremony. In the ceremony, Xavier was told to enter the forest andslay the Wandererthat made its home there.
After seven days, Xavier returns, the Wanderer’s protocore in his hands. However, rather than be overjoyed that he passed the trial,Xavier hugged the MCsilently, his entire demeanor dark. He hadnever been the sameafter his encounter in the forest, though he had yet to tell the MC what happened.
The next day, Xavier prepares to meet his Father at the royal palace. Before he leaves, the MCasks againwho gave him the star-shaped tassel. He admits that it’sfrom the woman he lovesmore than anything, but that she deserted him years ago.
He tells the MC thathe is not sad, because even though he has crossed paths with his lover again,she has no memory of him. The two talk for a while, the romantic tension in the air high, and without saying it outright, it becomes apparent that they arein love with each other.Xavier then leaves for the ceremony at the palace.
However, unlike in the past whenXavier would always returnwithin the timeframe he gave the MC,he did not return. No one knew where he had gone, and their teacher refused to talk about him. The MC continued her training andpassed the Lightseeker exam, the next step she needed to take to become Xavier’s protector.
During Xavier’s prolonged absence,the King died. The kingdom declared that after a200-year mourning period,a successor would be chosen. Those two hundred years were bleak without a ruler. The knights now had no one to swear fealty to, and theyseparated into squadsthe world over.
The MC continued training to be the best Knight she could be, determined that should Xavier come home one day, she wouldstand by his side again. Instead, she hadJeremiahat her side, the only person who she could still talk to about Xavier, though hisopinion of the prince had been damagedby his absence.
On a mission toStarfall Forest,the MC leaves her group in the night,distracted by an illusionin the woods. She thought she had seen Xavier and ran into the heart of the forest where shefell into a strange pocket realmfilled with stars. She believed she was dying until thereal Xaviertruly appeared and saved her from the darkness.
Xavier claims he had beenin Starfall Forestthe whole time, trying to hunt the Wanderers that keptrespawningthere after they were cut down. The two seem awkward around each other given the time they’d spent apart, but it’s clear theystill love one another.
Yet, when the MC presses Xavier for more details about their time apart, he continues to deflect. In the end, the MC — with the help of Jeremiah —pretends that she has been experiencing fitssince escaping the forest’s illusion. Xavier immediatelyfears that it is her heartand takes her to his spaceship to heal.
All incarnations of the MC seem to have a heart condition. This is likely due to theAether Corein their chests. Even though the MC in Xavier’s myth was unaware of a heart condition,Xavier had known for a long time.
Feeling guilty, the MC reveals that she had been pretending to be ill so that she couldgain cluesabout what he’s hiding. He eventually tells her that he hasdiscovered the secretthat Philos had been hiding this whole time.
He had learned that Philos was ahollow planet, built by humans. However, the planet wasslowly dyingas its core had been depleted. Xavier learned that since the humans on Philos werenearly eternal, the planet wasslowly siphoning their energyto keep itself alive.
Additionally, a side-effect of the energy transfer was thecreation of Wanderers. Xavier had discovered all of this during hisGladius Ceremony. He realized that theWanderers in Starfall Forest had once been peopleand that their Protocores were once human hearts.
The royal family had been sending humans into Starfall Forest forhundreds of yearsto keep the planet alive. Xavier found the practice despicable. Yet, when he returned to the palace before his father died, he learned that the royal family had found theperfect sacrificeto recharge the planet: a girl who could bereborn infinitely.
A planet that uses to survive doesn’t deserve to be saved.
His Titulus Ceremony was meant to be thefinal sacrifice. He was to takethe MCto the center of Starfall Forest so that she could be thrown into its heart anddie and be reborn again and again infinitelyso that the planet could survive.He refusedto partake in the ritual.
Xavier had created the Backtrackers to find analternative to the planet’s energy problem, not just to save the planet, but tosave the woman he lovedmore than anything. That woman was the MC, the one whose heart could be sacrificed endlessly to sustain the planet.
Understanding the importance of his mission,the MC promises to stay behindand rule in his stead.She will become queento protect the people they hold dear while hesearches for their salvation.
Xaviervows to reunite with herwhen she becomes queen, only this time, as her knight.
Even though the MC in the current timeline isdifferentfrom the MC who is the queen on Philos, Xavier believesthey are in essence the same person. To him, there isno distinctionbetween one or the other.
He proves this when he tells the MC in the myth that he hasonly ever received a star from one beloved, despite both women giving him a different star.
