“It feels weird to call someone master.”

What happens when one combines the Ainu Sitonai, the Finnish Louhi, and the Norse Freyja into one Servant? An adorable loli with a polar bear, that’s what! Sitonai serves as a single target Arts Servant, and is also the first non-limited Alter Ego Servant for Masters to summon.

Sitonai’s primary usage comes from her sustained damage. Having both a 3-turn Attack Up on Kamuy Yukar A and a 3-turn Arts Up on Emotional Freezing B, both with relatively low cooldowns, she can keep her Card damage higher for a longer time. She also has some nice survival options such as her invincibility on Snow Fairy EX. A 30% NP charge on Kamuy Yukar also provides her with easier access to her Noble Phantasm.

While she is incredibly cute, she is still incredibly lacking the umph that her Caster counterpart, Illya, has. Her damage is severely lacking due to her class typing, making her worse than many freely available options with respect to Noble Phantasm strength. She also suffers from poor durability when she does not have her hard survival skill up. To make matters worse, as an Illya-type Servant, she has to deal with chance based skills.

Masters looking for a non-limited Alter Ego would be best served to roll for her, and will find her most effective in roles against Cavalry and Foreigner Bosses. The loli goddess conglomerate will not disappoint. 


Sustained Damage

Sitonai comes equipped with two 3-turn damage boosts - one for her Arts and one for her Attack. This not only will allow her to hit harder on non-Noble Phantasm turns, but also to improve her (rather poor) base NP gain. 

Hard Survivability

Sitonai has two survivability tools up her sleeve - an Invincibility on a 6-turn cooldown, and her Noble Phantasm which causes a Dragon Enemy to lose one tick of their gauge. These hard survival options could help her last even longer in some challenging quests.

Gauge Charging

There is a huge difference in Fate / Grand Order between a 20% and a 30% charge, with a 30% allowing a Servant to use their Noble Phantasm with a 50% starting CE and either a Mage’s Association mystic code, or one of the many 20% gauge chargers.



(Plus a Polar Bear)


Alter Ego Classing (Offensive)

The best usage of an Alter Ego in the game is due to their ability to counter waves of Cavalry opponents of mixed classes. However, without an AoE Noble Phantasm, they are almost always outdone damage-wise by a regular counter-class. Sitonai is no exception, as her Noble Phantasm struggles to keep up with Noble Phantasms of many lower-rarity counter classes. The only time she does benefit from double damage where no other class would is against Foreigners, which are very rare as an enemy type. 

Alter Ego Classing (Defensive)

As an Alter Ego, Sitonai will receive neutral damage against all classes except Berserker (1.5x) and Foreigner (0.5x). While she has her hard survival skill, she will often be taking far more damage than she would against class advantage. One or two poorly timed Critical hits in more challenging quests could wipe her out prematurely.

Chance Based Skills

All Illya Servants have a skill based on chance, designed to incorporate Miyu or Chloe into the fight to buff her back up to full. Sitonai has a particularly brutal one, losing her 20% Attack up should the Chance Based skill miss, harming her already mediocre damage.

As a damaging Servant, Sitonai should primarily focus on skills which damage her enemy. Both her 2nd and 3rd skill should be leveled high (with her 3rd to 10 for the full 30% gauge), but her first skill fails to benefit significantly from leveling and can hence be left at minimal levels.

  • Snow Fairy EX gives Sitonai her hard survival and a team-wide damage cut. However, this damage cut improves only by a couple hundred points at max level making it near negligible in practice. A Master would only want to level this skill up to lower its cooldown, but for the most part it can be leveled last and only to level 4 (or 6 if 1st cooldown reduction is desired).
  • Emotional Freezing B provides Sitonai with an Arts Effectiveness up buff, which increases her lower NP gain rate as well as her damage. While it also provides Debuff Immunity, this is not particularly crucial in most situations. This skill can be leveled second. Masters lacking in resources could hold this at level 9 with no real loss.
  • Kamuy Yukar A is Sitonai’s charge, which also provides a chance at increasing her attack and giving the party Critical Stars. Like all charge skills, there is a huge difference between base and max, so this skill should always be leveled first to max level.

Craft Essence Recommendation

Like most damaging Servants, Sitonai works well with Starting NP Gauge CEs or Hybrid Starting Gauge / Damage CEs. Without either she could benefit from a Buff Success Up CE to minimize her chance of failing to maximize her damage.

  • Kaleidoscope / The Imaginary Element: Either of the two primary starting gauge CEs will allow Sitonai to unleash her Noble Phantasm instantaneously.
  • Holy Night Supper / Golden Sumo: Boulder Tournament / Painting Summer: With a 50% charge and a boost to damage, these CEs would allow Sitonai to increase her output at the cost of requiring a 20% support charger to top her off.
  • Secluded Beauty / Queen’s Dream: While not in NA yet, these CEs can lower Sitonai’s chance based skills’ failure rate from 1 in 5 to 1 in 10. While not perfect, it makes her a much more reliable Servant.

Gameplay Tips

While Sitonai can be effectively used against any Cavalry class, she is best used against Casters with Ozymandias. Ozymandias has the capability to both give her the 20% charge to complete her gauge (50% base from CEs + 30% self charge + 20% Ozy charge), as well as remove the chance-based element of her third skill with the +40% Buff Rate Success buff.

Character Info

This Heroic Spirit is a fusion of several Divine Spirits all in the body of a certain girl with a close connection to the Holy Grail. How exactly this was accomplished is similar to the summoning of Pseudo-Servants like Zhuge Liang, although her particular manifestation combines characteristics of a High Servant (a compounding of multiple heroes) and an Alter Ego (the distillation of a certain personality facet).

The one who became the vessel was not a human mage, but rather the latest model of homunculus created by the Einzberns. Her enormous Command Spell covered her entire body, her talent in magecraft was top class, and her abilities as a Master were even greater. In addition, she also functioned as the container of the Lesser Grail.

The True Name recorded for her Spirit Origin is "Sitonai," as she is the most prominent of the three Divine Spirits gathered in this vessel.

Profile 1

Height/Weight: 133cm, 34kg
Origin: Ainu Mythology, Norse Mythology, Finnish Mythology, etc.
Region: -
Alignment: Chaotic-Good
Gender: Female
Apparently she's afraid of cats.

Profile 2

A girl with an innocent smile. And yet, she hides an immeasurably cruel side as well. Her personality is indeed quite similar to the homunculus who serves as her body. The bravery that lets her fight so uncharacteristically for a girl her age comes from the Ainu's young heroine Sitonai. Her sympathy and melancholy towards those for whom she has deep affection comes from the goddess Freyja. The iron will that lets her murder enemies in cold blood comes from the witch Louhi.

...At least it's easy to attribute all these various aspects of her personality to the goddesses that fused to create this Alter Ego, but for now, her general personality comes from her vessel.

Profile 3

Snow Fairy: EX
The evolved form of the skill "Child of Nature."
So long as the user believes her target must be attacked, even loved ones are not safe from this icy cold. This ability freezes all nearby targets.

Frozen Emotion: B
Chilled empathy. Indifference.
The mindset of an innocent, smiling girl who is capable of turning on a dime, becoming a vicious demon...weaponized. An ice-cold heart can sometimes be a sword, and at others, armor.

Profile 4

Kamuy Yukar: A
An epic song in which the performer plays the part of the Kamuy. As an Alter Ego, performing Kamuy Yukar enables her to borrow many of the Kamuy's powers described in Ainu myth. Even the powers related to the higher-ranked Kamuy, Pase Kamuy of the mountains, village, and open sea, can be used.

Red Gold: B++
A skill related to the Norse goddess Freyja.
Even though Freyja enthralled various deities and even enemy giants, she loved only one person. When her loved one left on a journey, Freyja was said to have wept tears of red gold out of concern for his welfare.
This skill is typically not used in this game.

Howl My Friend, My Power.
The hunting dog who served as companion to Sitonai, the girl hero of Ainu, became a kind of familiar. Louhi and Freyja's magecraft from the Age of Gods strengthened it, and now it appears more like a large bear instead of a hound, making it closer to a spirit.

"A familiar for a goddess should be massive, and it wouldn't be fitting if it was some Demonic Beast or Phantasmal."

...That's what Louhi said anyway, and Freyja agreed. So with two out of three votes, the familiar became a bear.

This Noble Phantasm is continuously active. When its True Name is revealed, the familiar releases a series of vicious attacks before Sitonai fires an arrow imbued with icy magical energy at the target. Sitonai's characteristics triggers a special effect against dragons.

Ascension 1 Wow! I have a new look!
That's interesting.

I can? So that's how this works.
Ascension 2 This is different than when my magical energy goes up...
My vessel's changed.
Is this another way of saying...growth?
Heh heh, this makes me happy.
Ascension 3 Okay. When my Spirit Origin changes enough, my appearance changes as well. I'm starting to get it. And the powers of the goddesses seem to get stronger too.
What do you I look good?
Ascension 4 Calling someone "Master"...feels a little backwards...
But I'm a Servant now, so it only makes sense for me to have a Master.
Let me say it again: take good care of me, Master!
Bond Level 1 This body's name is Illyasviel von Einzbern.
I think my personality is pretty close to hers too.
Do you know of the Einzbern family?
Bond Level 2 There are three goddesses who lend me their power.
One is the Norse goddess Freyja, then there's the Witch Louhi of Finland, and finally Sitonai of the Ainu.
I think Sitonai is probably closer to a Heroic Spirit, rather than a god...
Bond Level 3 Shirou?
That bear is my Noble Phantasm. Actually, he's supposed to be Sitonai's hunting hound and friend, but for some reason he ended up a bear.
It seems like Louhi and Freyja did something to him...
His name?
Well, I took the name from one of this body' of Illyasviel's memories.
Shirou...a name of someone who is precious and who should never be forgotten.
Bond Level 4 It's my first time being a Servant, so I'm a little nervous.
But I see that you're a good person.
Yep, I'm glad that a nice person like you is my Master.
Bond Level 5 I have a favor to ask you.
Um...there are a few names that I found on the list of Heroic Spirits registered as Servants in Chaldea that I'm curious about...
Could I...ask what kind of Heroic Spirits these people are...?
Conversation 1 Are you sleepy?
You look out of it.
Are you telling me you're tired?
Conversation 2 Heehee. I'm older than you, so you have to do what I say. My punishments can be really brutal!
Conversation 3 Master and Servant, huh?
No, never mind.
Don't worry about it, Master.
Conversation 4 (Pārvatī) Pseudo-Servants of Babylonian and Indian goddesses...
I see. Those two were summoned as well.
So? Which one is more your type, Master?
Conversation 5 (Emiya (Alter)) The Heroic Spirit of Wrought Iron. A nameless Guardian, huh?
Of course he's here. After all, Humanity's in trouble.
Wait a minute. Doesn't he...look weird?
Where's his signature red coat?
Don't tell me Shirou turned into a delinquent!?
Conversation 6 (Emiya (Assassin)) Who is that hooded Assassin...? No, never mind.
He must be someone who never came face-to-face with his fate.
I wonder which one is a more cruel end to him...?
Conversation 7 (Irisviel (Holy Grail)) Um, I just saw a really beautiful person. I wonder what Heroic Spirit she is!
She was wearing a formal white mage's dress, and she had a crown on, and she was very...I mean, maybe a kind of sexyish big sister kind of person!
She's definitely the sort I can admire and want to be like someday!
Conversation 8 (Scáthach-Skadi) I don't have any memories from the Lostbelt, but I suppose this is the second time we met.
From now on, we'll be working together...right, Scáthach-Skadi?
Conversation 9 (Chloe von Einzbern, Illyasviel von Einzbern) A magical girl?
But I don't use any magic, and don't carry a wand either.
Heehee. What are you talking about?
Conversation 10 (Jaguar Warrior) Master! I just saw an outrageous Servant! I can tell just by looking that she's not to be trifled with! I have a feeling I'll never be able to beat her no matter what!
That cat must be a powerful god summoned as a Servant...
Eh? She's not a cat? A Jaguar? And I know her?
Now that you mention it...that face does look familiar...
Conversation 11 (Gilgamesh) I'm disappointed that you've formed a contract with THAT guy.
Who, you ask? That Archer... Who else!?
Ugh, I have this urge to rip out his heart! I want to ambush him so I can hear him shout something like, "You bastard!"
Conversation 12 (Gilgamesh (Caster)) I just saw the more brazen, but also genuine King of Heroes!
...Wait a minute. He seems different.
Don't tell me he's actually a useful Heroic Spirit when he becomes honest?
Conversation 13 (Heracles) Heehee... Berserker really is strong.
Likes What I like?
I like snow. It's white and fluffy even though it's cold.
It's like a white apron, don't you think?
Dislikes I don't like being cold.
But I don't really feel cold so much now, so it should be okay.
About the Holy Grail There're many kinds of Holy Grails.
Including myself...
Well, did you know that this body was a Holy Grail too?
It was called the Lesser Grail. But it isn't one anymore. Now, it's...
During an Event It looks like Shirou wants to go out...
Are you in the middle of something?
Birthday Happy birthday.
How would you like to celebrate your special day?
Summon I made Sitonai my True Name.
It seems like she's the most prominent one within me.
Please take good care of me, Master.
The Land of Mystique, Oniland! The Great Oni and the Kamuy's Gold 1 Um. How are things?
Let's work hard together until the very end.
The Land of Mystique, Oniland! The Great Oni and the Kamuy's Gold 2 Good work. Made any progress?
The Land of Mystique, Oniland! The Great Oni and the Kamuy's Gold 3 Hm.
I had no idea you were such a hard worker!
The Land of Mystique, Oniland! The Great Oni and the Kamuy's Gold 4 Teehee. This feels strange.
Even though the Holy Grail is involved, nobody dies over it.
...That's weird.
The Land of Mystique, Oniland! The Great Oni and the Kamuy's Gold 5 Oh, right.
Mash was saying that you should keep on checking on the, umm, information and announcements.
