Stories
7Character details
A hero of the Celtic legends of Ulster.
A member of the Red Branch Knights and the most formidable warrior of Ulster.
He's the hero who wields a lance inherited from his mentor Scáthach, Lord of the Land of Shadows.
He is also a formidable user of Runes - a Magecraft based from Norse legends.
Profile 1
Height/Weight: 185cm, 70kg
Origin: Celtic Mythology
Region: Europe
Alignment: Lawful-Balanced
Sub-Attribute: Heaven
Gender: Male
Doesn't wear metallic equipment when he is a Caster.
Profile 2
When he materializes as a Caster, it is different than when he materializes as a Lancer.
He uses a diverse range of Magecraft to torment his enemies.
Specializing in powerful attacks using heat and fire, it is assumed that he uses the "Ansuz" runic letter.
Profile 3
Rune Spell: A
He possesses Northern European magical crests called Runes, given to him by Scáthach. By using them, he can create powerful and diverse effects.
However, he cannot use multiple Runes at the same time.
Profile 4
『Wicker Man』
Rank: B
NP Type: Anti-Army
Cage of Scorching Flames. A giant consisting of countless thin branches appears. The giant sets itself alight, and attacks the enemy to deal powerful heat and fire damage.
Profile 5
The cage in the torso of the giant that appears as a Noble Phantasm is empty, so as a result the giant rages on, seeking sacrifices for the gods.
This is not an arcanum of the runes, but a Noble Phantasm the Celtic druids gave to the Child of Light who materialized as the "Celtic Mage" controlling fire and heat.
Additional profile
When he materializes as a Caster, it is believed he imposes the role of a "guide" to himself.
Not as a true druid, but as a temporary one...
As long as they are together, he will continue to guide and illuminate the path his Master shall walk on.

- Bond Level 1
- I'm countin' on you, Master. You won't be able to use me like normal, but do what you gotta do.
- Bond Level 2
- A Saber-class summon... I'd love to give that a try one day.
- Bond Level 3
- How many times have I manifested now? It's my first time as a Caster, though.
- Bond Level 4
- This is a "Holy Grail War" too, in a sense. I just hope my experience can be of use.
- Bond Level 5
- You're not half bad as a commander, Master. ...I mean, you've really grown from the baby you were last time. Guess that means I know how to pick 'em!
- Bond Level 5 (After Completing Part 2 Chapter 6)
- Grim the Sage is just an assumed name I use in this world. But my true identity is a hardworking, good-humored man who was forced to work by some capricious god. But then again, it was a big role that was worth taking on! Thanks to your decision, the sacred sword was confirmed. Now all we have to do is to beat the crap out of that crazy alien god!
- Conversation 1
- It's nice to relax sometimes, but weren't we supposed to be saving the world?
- Conversation 2
- About this whole Master and Servant thing... People talk about Master luck, and... Uhh, actually, forget I said anything.
- Conversation 3
- Well, I'm expecting a lot out of you as a Master.
- Conversation 3 (After Completing Part 2 Chapter 6)
- All bets are off for me the moment you cross the border into the fairy land. I'll leave the big job that's bound to come...to the real me.
- Likes
- Stuff I like... Right now, what I need is my spear, but... It's been sealed.
- Dislikes
- What do I hate? When I'm in Caster-class I guess it's those two, Medb and Morgan. I'd rather not see 'em. Got nothin' but bad memories of those two.
- About the Holy Grail
- The Holy Grail... I have run into that thing here and there quite a few times.
- Conversation 4
- I just can't relax... I don't need anything more than a flap of leather for protection...
- Conversation 5
- About the name of my Noble Phantasm, don't you think we should change it to somethin' a little more modern and simple? Original Rune, Matrix Ordyne! ...Oh, uh, sorry. Forget I said anything. Damn that was embarrassing!
- Conversation 6
- ...There aren't any fishing holes around here, huh?
- Conversation 7
- You wanna learn Rune spells? Uhh... Well... I'll teach you later. Yeah, later.
- Conversation 8
- Huh? You're saying I'm not using the runes in the proper way you taught me? Ha, that's far from the truth, my mentor. Have you finally gone senile? I'm just kid... I said I'm kidding! Don't kick your spear at me!
- Conversation 9
- Hey, you're Skadi from the Lostbelt. I'm in your...no never mind. It's too late in the game for me to say anything.
- Conversation 10
- Oh it's you, Brynhild. How ill-fated for you to be here.
- Conversation 11
- What's wrong, Sigurd? Do me a favor and don't look at me too closely through those glasses of yours.
- Conversation 12
- I'm the successor of the well of wisdom, huh? I'll have you know that it's not my fault that this role fell into my lap! Eh? I'm telling you it's definitely because I have connections with Scáthach! I KNEW she was a no-good mentor!
- During an Event
- Looks like something cool's goin' on. Should we go check it out too?
