Dang, you just beat me to it. I was going to state that,lol. Well, might as well think of something to go with it. ....... ..... .......... I got notthing, heh.
Then let's discuss the cast... Someone shoot me if I'd better stop.
Kamen no maid Sakuya = Dark Knight Cecil Time stopping Sakuya = Paladin Cecil Meiling = Kain Alice = Rydia Flandre = Original king of Baron (Odin) Remilia = Rosa, the main character romantic interest Patchouli = Cid, for inventing "magical" flying aircrafts
Reimu = Rubicante, the flame elemental boss Nittori = Cagnazzo, water elemental boss Aya = Barabariccia, wind elemental boss
And perhaps the Subterranean Animism cast as dwellers of the subterranean world... (Oh, my, what a twist...)
Last time I checked Mokou never placed a little girl who wanted to go flower gazing under house arrest, rob a village and prevent an innocent girl from being revived, strip Gensokyo of it's defenses against a Lunar invasion, oppress other religions, endorse slave labor, or KILL AN ENTIRE WORLD for it's creator's belief in the free market.
Personally, I think Meiling would fit better as Yang than as Kain, and Nitori would make the best Cid (Patchouli would make a good Tellah).
Also: Kaguya as Golbez Eirin as Fusoya Lyrica as Edward Yuki and Mai as Palom and Porom, respectively Yukari as Zeromus
Four Fiends: Yuyuko as Scarmiglione (due to both being more powerful in death) Murasa as Cagnazzo Aya as Barbariccia Mokou as Rubicante
Summons: Mystia as Chocobo Sasha(Fan character) as Mist Dragon Iku as Ramuh Letty as Shiva Rin as Ifrit Tenshi as Titan Konngara as Asura Flandre as Odin Utsuho as Bahamut
Uhhhh, Remilia would be better as Odin, since she wields the Gungnir, the trademark weapon for Odin, also, the king of Baron was something like the boss of Cecil so... it fits, Flandre would be better if she is a fucking Brachiorados or something
Yeah, you're probably right. I was going to suggest Remilia as Kain due to her use of spears and frequent partnership with Sakuya in Touhou (such as Imperishable Night), but I guess the role of Odin would suit her better. Better than casting her as Rosa, of all people.
However, there's still the matter of who would fill the role of Kain (if Meiling were Yang).
