オレの乗騎？

ああ、大海蛇（シーサーペント）な。
水竜でも何でも好きに呼んどきゃいいさ。

オレにはとんと覚えがねえから、
またぞろポセイドンのクソ海野郎の仕業だろうよ。
ま、この霊基に紐付いちまってンだろうなァ。

大海蛇はな、竜種なんだぜ。
すげーだろ。
細かく言うと竜種のそのまた亜種だったか？
魔術師連中に言わせりゃ幻想種の一匹ってあたりだ。
ホームズやエルメロイⅡ世あたりは確か、
「ネッシーの元ネタ」とか言ってたっけな。
オレも昔にゃ、地中海で一匹ばかし殴り合って……

ん？
宝具の大海蛇はもしかしたらソイツなんじゃ、って？

……ハハ！
そりゃいいや。おもしれえ。
いっちょ、本人に訊いてみるとするか！

My mount? Oh, you mean my sea serpent. Just call it whatever you want. Water dragon, Mr. Serpent, Scalefred, whatever. I don't remember much about it, but I'm sure that rat bastard Poseidon's got something to do with it. Ah well, however it got here, it looks like it's tied to my Spirit Origin now.

Did you know my sea serpent's a dragonkin? Pretty cool, right? Well, technically, I guess it's a dragonkin variant or something? The mages say it's a Phantasmal. I think Holmes and El-Melloi II said it was the original inspiration for Nessie or some shit? You know, back when I was alive, there was this one sea serpent in the Mediterranean I used to fight all the time...

Hm? You think that might be the sea serpent in my Noble Phantasm? ...Hah! Interesting idea. I like that. I'll have to ask him about it sometime!
