Biography

Unlock Description Translation
Default サーヴァントユニヴァースより来訪した天涯孤独のヴィラン(悪役)。

世にも珍しい文系のバーサーカー。
魔力転換がオルトリアクターを燃やし謎のヒロインXの打倒を誓う、対・対セイバー用決戦兵器。

もう訳が分からない、だって?
───考えるな。感じるんだ。

A Villain (antagonist), the last of her kind, on a visit from the Servant Universe.

A hard-to-come-by literary Berserker.
An Anti-Anti-Saber final weapon who swears to defeat Mysterious Heroine X whilst fuelling her magical energy converter, the Altreactor.

You don't know what's going on anymore, you say?
---Don't think. Feel.

Bond 1 没落の騎士ペンドラゴン卿

身長/体重:154cm・42kg
出典:2017年バレンタインイベント
地域:サーヴァント界
属性:中立・悪  性別:女性
じまんのつるぎ『邪聖剣ネクロカリバー』はあやしいつうはんでかった。

Fallen Knight Sir Pendragon

Height/Weight: 154 cm / 42 kg
Source: 2017 Valentine's Event
Region: Servant World
Alignment: Neutral Evil Gender: Female
Her prided sword, ‘Wicked Holy Sword Necrocalibur’, was bought online from a shady vendor.

Bond 2 「闘うよ。ヒロインXを倒し、

 宇宙をヴィランの闇色に染める、その日まで」

そう誓う彼女をヴォロイド“K6ーX4”
通称“黒騎士くん”はいつも陰から見守っている。
適当に隠れてサボっているとも言う。

‘I'll fight. Until the day I defeat Heroine X,

and stain the universe with the darkness of villainy.’

The voroid ‘K6-X4’—a.k.a. ‘Black Knight-kun’—is always watching over the girl and her oath from the shadows.
In other words, he's hiding away and being lazy on a whim.

Bond 3 まじめでひかえめな態度の少女。

好物は甘味。隙あらば高級和菓子を所望してくる。
割と金のかかる腹ぺこ。
オフの日は黒い円卓型のこたつから一歩も出ず、読書をしたり音楽を聞いたりして過ごす。

基本ずぼらで面倒くさがり。
他人からの命令や指図には、皮肉を返しつつもそれなりに素直に従うのは不思議。
甘い物で釣ると早い。

A serious and reticent young girl.

Has a sweet tooth. If you give her the chance, she'll request luxury Japanese sweets.
A relatively costly glutton.
On days off, she doesn't take a single step away from the Black Round Table-type kotatsu.

There, she spends her day reading books and listening to music.
She's basically a slob who can't be bothered.
Curiously, she will follow orders and instructions, obedient in her own way, albeit served with a side of sarcastic retorts.
Bait her with sweets to get her going.

Bond 4 魔力転換炉オルトリアクターは、体内に秘めるオルタニウム結晶を触媒として、カロリーを魔力へ変換する。

「和三盆の成分バランスが最大効率です。あとお茶もほしいです」と彼女は強調する。
眼鏡はブーストされた視神経を休ませるために必要なアイテム。掛ける間はむしろ視力が落ちる。

彼女が所持している謎のアイテム「∞(インフィニティ)黒餡子」は欲求(ソウル)、糖分(パワー)、売り場(スペース)、原価(リアリティ)、製作(タイム)、需要(マインド)という六つの原始力によって作られたもので、持つ者に無限の力を与えるというがX・オルタはよく分かっていない。

The magical energy converter, the Altreactor, converts calories into magical energy, the Alternium crystals hidden in her body acting as a catalyst.

‘The component balance of wasanbon sugar is the most effective. Also, I'll have some green tea,’ she emphasizes.
Spectacles are a necessary item to rest her boosted optic nerves. In fact, her eyesight deteriorates when putting them on.

The mysterious item in her possession, the ‘∞ (Infinity) Black Bean Paste’, was made through the six fundamental forces of
Desire (Soul), Sugar (Power),
Sales Location (Space), Cost Price (Reality),
Production (Time), and Demand (Mind).
Although said to grant infinite power to its wielder, X Alter doesn't really have a clue.

Bond 5 すでに壊滅し失われた暗黒の騎士団ダーク・ラウンズに連なる最後の生き残り。

付与されし称号はペンドラゴン卿。

念動力“オルタ・チョーク”、腕先から魔力を放出する絶技“オルト・ライトニング”など、どこかで見たような多彩な技を駆使する。
赤い魔力を放つ“邪聖剣ネクロカリバー”はツインブレードやチェーンソーなど自在に変形するが、よく壊れて爆発する。
格好いい武器ほどあまり強くない、というのは宇宙共通の掟らしい。
やはり何の変哲もないロングソードこそ至高。

The last survivor of an annihilated and lost order of dark knights, the Dark Rounds.

The title bestowed on her is Sir Pendragon.

She employs a variety of strangely familiar techniques such as the psychokinetic "Alter Shock" and the ultimate technique ‘Alter Lightning’, which releases magical energy from the forearms.
Emitting crimson magical energy, the ‘Wicked Holy Sword Necrocalibur’ can be transformed into a twinblade or chainsaw at will, but frequently breaks and blows up.
It seems to be a universal law
that cool weapons aren't very powerful.
All said and done, nothing beats the standard longsword.
