Unlock Description Translation
Default 聖杯に縁ある人物を核として




An existence created by the fusion of multiple heroic (divine) spirits, with a person who is connected to the holy grail as a core.

Although the materialization can be regarded as similar to pseudo-servants such as Zhuge Liang, the true nature of its existence is a composite of heroes, a high servant. Similar to pseudo-servants, the one with the strongest ego will be selected and manifest as an alter-ego.

The individual who became the vessel was not a human mage, but the latest and last homunculus created by the Einzberns. Possessing large-scale Command Spells that covered the entire body, the quality of her magecraft is first-rate, her performance as a Master was said to be top class. She also secretly held the ability to function as a Lesser Grail.

The True Name registered on the Saint Graph is Sitonai. This seems to be due to the fact that out of the three Heroic (Divine) Spirits gathered in the vessel, Sitonai appears to be the most strongly apparent.

Bond 1 身長/体重:133cm・34kg

属性:混沌・善   性別:女性

Height/Weight: 133 cm, 34 kg

Source: Ainu, Nordic, and Finnish mythologies.
Origin: -
Alignment: Chaotic good
Gender: Female

Not good with cats.

Bond 2 純真な笑顔を浮かべる少女。



A girl who shows a pure smile.

However, that smile hides a great cruelty----

Personality-wise, she resembles that of the homunculus who became the base. The young Heroic Spirit Sitonai of the Ainu who displays the courage to fight unfitting of her age, The goddess of love Freyja who shows sympathy to her opponents, and the witch Louhi who mercilessly slaughters her opponents... While her personality matches these aspects of the beings fused into the Alter Ego, for now it takes after the personality of 'the girl who became the vessel'.

Bond 3 スノーフェアリー:EX



Snow Fairy: EX

An evolved version of the skill Child of Nature. Once it is designated as an attack target, even loved ones can be frozen. The ability to spontaneously freeze any surrounding target.

Emotional Freezing: B
Freezing the emotions. Becoming emotionless. While she is a girl who smiles innocently, her thoughts can sometimes become like that of a cold-hearted demon, and her mental state can be wielded as a weapon. The heart of ice may sometimes become a sword, or it may sometimes become an armor.

Bond 4 カムイユカラ:A



Kamuy Yukar: A

The divine hymn of he who claimed himself a Kamuy. As an Alter Ego, uttering the Kamuy Yukar allows her to borrow the power of various Kamuys within the Ainu lore. It is possible to use the power of even the Pase Kamuys (the superior Kamuys) related to mountains, villages, and the sea.

Crimson gold: B++
The skill of Nordic Goddess Freyja. To Freyja, who attracted not only gods but also even hostile giants, loved only one individual. It was said that tears of crimson gold flowed out as Freyja wept thinking about him, who lives only to travel. However, this skill is not used in this work.

Bond 5 『吼えよ我が友、我が力』

ランク:EX 種別:精霊宝具
レンジ:1~20 最大捕捉:1



"Howl my friend, my power"

Rank: EX
Type: Spirit-type Noble
Range: 1~20
Maximum target: 1
Oputateshke Okimunpe
The hunting dog who was friends with Sitonai, the Heroic Spirit of the Ainu, has become a type of familiar. Strengthened by the magical energy of the divine spirits Freyja and Louhi, it changed appearance from a hound to a bear; and its existence has become close to that of an Elemental.

If it's a goddess' familiar, a fierce and large appearance is rather fitting, but it won't do for it to be a phantasm or mythical beast--- as a result of Freyja accepting that claim from Louhi, two out of three agreed to turn it into a bear.

A permanently active Noble Phantasm. When its True Name is invoked, consecutive attacks consisting of [a charge attack by the dog (bear)], [a bow-and-arrow attack filled with ice magic], and [a slash from Sitonai] will occur like an avalanche. Due to Sitonai's nature, it will apply a special effect against dragons.
