Yuri is the main character of the game. He is Chelinka's twin brother and very close to her. Although curious, kind, and friendly, he isn't so bright at first. Unfortunately, fate is unkind to him thanks to a strange power he and Chelinka share.
- Break the Cutie: The entire game. The entire game.
- Character Development: Yuri before the timeskip and Yuri after the timeskip are markedly different.
- Cloudcuckoolander: He thinks a coffin is a treasure chest and doesn't realize that the wispy and transparent girl who appears after opening it is a ghost.
- Determinator: There is absolutely nothing in the universe or any universe that will stop Yuri, so long as he has Chelinka.
- Fearless Fool: As a young child he just does not understand why Chelinka is scared of the monster-infested cave, giant monsters, and ghosts.
- Heroic R.R.O.D.: If he uses his crystal power without Chelinka, he has to Cast from Lifespan. Both times he tries it nearly kills him.
- Heroic Safe Mode: He becomes Chelinka's caretaker during her catatonia following Latov's death, doing all the household chores and training himself to fight with a sense of dutiful routine. When Chelinka finally comes to, a few years later, Yuri's calm is shattered and he shows all the emotion he couldn't express.
- The Insomniac: He sleeps a few hours every three days.
- Kid Hero: Although there's a timeskip of a few years, it only takes him from 6 - 8 to 10 - 12.
- Living Emotional Crutch: To Chelinka.
- Malaproper: On the first trip into Rebena Te Ra, he proclaims that he is "practically adulterous" and wonders if a townsperson is a "clair-voyeur."
- Missing Mom: Apparently died when the twins were young. It turns out she was abducted by the Lunites and kept in suspended animation.
- Orphan's Ordeal: His widower father is killed in front of him and his other guardians disappear, forcing him to take care of his catatonic sister, alone, for several years.
- Promotion to Parent: Due to Chelinka's catatonia, he takes over all the household duties for several years.
- Reality Warper: More like Reality Hopper. His and Chelinka's power is to create and move to Alternate Universes at will.
- Unfortunate Names: Although Yuri is a common Russian name, which fits with the rest of the family, it still raises eyebrows in fandom.
The co-protagonist and Yuri's twin sister. She was born a few minutes earlier (a fact she occasionally flaunts), and curiously, holding a small green crystal in her hand. She can make this crystal shine at will, hinting at a mysterious power. Although she doesn't participate in combat, her importance to the plot and her brother make her a central character.
- Anger Born of Worry: Towards Yuri, quite often.
- Blessed with Suck: Like her mother, she is a Starsinger—a power that seems to bring tragedy onto anyone who possesses it. Damn Lunites.
- Bookends: During the timeskip, she is catatonic and Yuri is her caregiver. In the ending, she is his caregiver while he slowly dies from power overuse.
- Break the Cutie: Just like Yuri.
- Closer to Earth: Even after Yuri gets his head out of the clouds, she takes this role.
- Cloudcuckoolander's Minder: When they're young, she tries to keep Yuri in check.
- Cute Mute: After Latov's death, but she regains her voice in Rela Cyel. She communicates via telepathy instead.
- Heroic Sacrifice: In the end, she seems to sacrifice her very existence to save Yuri's life. She gets better.
- Living Emotional Crutch: To Yuri. So much so that when she uses up the last of her power and seemingly dies, the Yuris and Chelinkas from every other reality just make a new one.
- Neutral Female: Kind of. She's absent during dungeon sequences and fights, apart from one particular boss fightnote which is explained as Yuri and the others guarding her. However, Yuri can't cast magic without her being there.
- MacGuffin Super Person: Being the wellspring of the twins' crystal power is why the villains are after them.
- Plucky Girl: As much bad stuff happens to her as to Yuri, but she keeps going with a will.
- Power Incontinence: Due to the way her and Yuri's ability operates—she has the power, and he focuses and directs it.
Alhanalem is a Yuke who lives at the Villa and acts as a tutor to the twins—at least, he tries to. He used to serve King Kolka and was a high-ranking researcher in Rela Cyel, and knows a great deal about magic and crystals.
- And I Must Scream: Spends several years trapped in an evil red crystal, until Yuri and Chelinka free him.
- Badly Battered Babysitter: Between overenthusiastic hugs and not being listened to, he has his work cut out for him.
- Butt Monkey: If he's not being knocked over by the twins, then Meeth is dropping a pot on his head. And if he's not a slapstick victim, someone is probably taking the mickey out of him verbally.
- The Bore: Occasionally lapses into overlong lectures about magic, magic machinery, and how it works, which makes the kids wander off.
- Fantastic Science: His study of magic and crystals, which played a large part in the construction and maintenance of Rela Cyel.
- Mr. Exposition: He's the guy who explains most of the crystal stuff. He, along with Meeth, also shares the story of what happened with their parents, Rela Cyel, and the Temple.
- Noodle Incident: The twins once saw him without his mask, something that apparently caused a need for Brain Bleach.
- O.O.C. Is Serious Business: When you go into town with Alhanalem during the Moogle Plant mission, you can talk to a woman who is attempting to spy on the temple. Al warns her repeatedly not to do this but she is indignant. Talk to her again, Al warns her one more time, but with a sentence that doesn't end with a word that ends with the "-AL" suffix which makes the woman even more nervous than she already is.
- The Professor: A noted scholar on magic who was once a personal adviser to King Kolka.
- Squishy Wizard: He tends to be pretty fragile, and the damage output of his magic bombs come from his magic stat rather than attack.
- Verbal Tic: Ends all his dialogue with words ending in an -al sound, including words like presentable (presentab-al). Which irks a guard at Rela Cyel, who doesn't like the control rods being referred to as "magical fantastical."
A Lilty alchemist and the second friend of the family at the Villa. Although Meeth is an expert at her craft, she is very odd, speaking in a childishly cutesy way and recording her "grudgies" meticulously. Nevertheless, she's a steadfast friend to the twins.
- The Aloner: When the Temple invades the Villa, Meeth is stuffed into her own pot and rolled down the hill, landing in the ruins of Rela Cyel. She spends the next few years with only books and monsters for company.
- Cute Bruiser: After leveling her up some, she can trash enemies. With a touch of Genius Bruiser too.
- Create Your Own Villain: She has a very powerful "grudgie" against the Coelacanth for preventing her escape from Rela Cyel's ruins. When the party goes to Rela Cyel of the past, Meeth immediately attacks its past self and Alhanalem speculates that's why it became so vicious in the first place. She's not pleased.
- Get a Hold of Yourself, Man!: Delivers these with either ladle or pot.
- Hammer Space: This seems to be invoked. The pot appears in a puff of smoke whenever she needs it, and at one point she summons it over Alhanalem's head.
- Heterosexual Life-Partners: She and Alhanalem share a house and are very close friends from way back, but there's no romance.
- Go Mad from the Isolation: She was showing signs of it when the party finds her "house" in Rela Cyel, talking to and answering herself and taking a while to see that there are other people there.
- Improbable Weapon User: Ladles and an alchemy pot.
- Inelegant Blubbering: Several times.
- Magikarp Power: Initially, her best use is as a support character. Once she starts getting to high levels, though, her damage output is comparable to Yuri's.
- Older Than They Look: Just don't ask how old.
- Parental Substitute: She sees herself as this to the twins.
- Stone Wall: Even though her damage output can grow to be as good as Yuri's, her ladle will never be as good in melee combat.
- This Is Unforgivable!: She fills fifteen notebooks full of her "grudgies" during the timeskip, mostly against the monsters in Rela Cyel.
- Verbal Tic: She ends all her sentences with a cutesy -ie sound (blankie, cloakie, etc).
Gnash is a Selkie boy who lived in Abyssus Forest and has no prior relation to the twins, or any part of the main plot. He joins the party to repay them for healing him of a poison plant and stays with them throughout the game.
- Because You Were Nice to Me: "Forest people no forget."
- Cutscene Power to the Max: Gnash can double-jump and the player can exploit this with creative stacking of items. But when the party is stuck at the bottom of Rela Cyel's central shaft, Gnash jumps offscreen in a single shot and climbs a completely smooth wall to the surface.
- Doomed Hometown: Talking to him during an optional visit home reveals that he was the only survivor of a sickness that struck his village.
- Double Jump: A technique unique to Selkies, which is endlessly useful.
- Extreme Omnivore: He even judges whether someone is a good guy or a bad guy by tasting them.
- Funny Background Event: He starts fake-tussling with one of the royal soldiers while King Kolka and Alhanalem are realizing how disastrous the forthcoming eclipse could be.
- Lightning Bruiser
- Odd Friendship: With Meeth. They spend several moments exchanging facial expressions when they meet, which is apparently enough.
- Raised by Wolves: Raised by the forest in general, really.
- Speaks Fluent Animal: Talking to the town animals will result in him commiserating with their troubles and giving advice. Notably, he speaks proper "English" when conversing with them.
- Wild Child: Although he's able to quickly befriend the party, his speech is broken and he has trouble remembering his own name thanks to the lack of contact with other people.

The twins' mother. She was a starsinger, blessed with the ability to see the future and great power as a crystal user, but she died not long after Yuri and Chelinka were born. She is actually still alive, but not by much as she is being used as a living power source by the Temple.

- Heroic Sacrifice: Willingly gives herself up to the Lunites in order to protect the twins. Unfortunately, they go after the twins anyway when her life starts to fade.

- Berserk Button: Defacing his mask.
- Card-Carrying Villain: He really enjoys tormenting a pair of six-year-olds and killing their father in front of them. Strangely enough, though, he eventually becomes the non-evil (but very odd) proprietor of the crafting shop in Multiplayer.
