Something else: Maybe having Taiga learn about shirous magic at somepoint after Kiritsugus death. Perhaps her sneaking into Shirous workshop when he's distracted by making a circuit for whatever perpose.
Idea: Maybe the Taiga Clan could be privy to magic and Taiga happens to become a master.
The first idea....it's too easy for Shirou to potentially talk his way out of it. Not impossible though. It's the least interesting to me though.
The second idea though? Yes. It's quite a bit of revision, but I'd love to see Taiga as a Master. Hmm...what Servant would she want to summon, what Servant would she actually get, and what Servant would help her best?
Finally, unless she summons Assassin or forces someone else to summon Assassin, she's stealing someone's spot.
The easiest spot for her to take is Bazett. Would Kotomine troll Taiga like he did Bazett? It may not be worth the risk given Taiga's connections to the Yakuza, although the idea of a one armed Taiga hunting down Kotomine will the Yakuza at her back is bleak if entertaining mental image. You could make a Route about that. Once Shirou finds out why and how Taiga lost her arm, Shirou and Saber would probably be on board with helping.
That, naturally, gets them into a fight they really aren't prepared to fight. They somehow escape and spend the rest of the route being hunted down and seeking refuge.
If Taiga summons a Servant, then if a more light hearted story is desired, she should have a Servant who shares her infectious cheer and over the top personality.
I think she'd want to summon Saber first and foremost, followed possibly by Lancer. I can totally see her wanting to summon a Caster from the Age of Gods because that seeing that kind of magic would be AWESOME. The last Servant she wants to summon is Assassin.
Finally, all this talk of Bazett gives me an idea: is there a way for Taiga to stumble across Bazett and get herself stuck in the Holy Grail War that way? I don't know if Bazett would willingly give up the information, or if Taiga knows more than she lets on via the mob, but there could be just enough miscommunication that Bazett lunges at the chance to be avenged.
For instance, Taiga thinks that the Association is the local branch of Yakuza. She goes digging for information and finds out more than she expected.
One of the highlights of this route: TAIGA VS KUZUKI!
Or Taiga and Partner vs Kuzuki in a Handicapped Match, since he would probably have his Reinforcement unless he can be separated from Caster.
Discuss.
