[X] Go to the Matou manor.
-[X] Knock on the door, and attempt to buy Sakura's freedom with Capitalist's funds.
"Capitalist, have you ever met a man who couldn't be bought for the right price?" Your familiar gives you a polite smile, knowing where you're going with this.
"Only one," Capitalist replies. "And he died long ago." With that, the two of you set off through the streets of Fuyuki City towards the Matou mansion.
Of course, that's what you would do if you knew where the Matou mansion was. But you don't. So instead, you have to go to the library and look around for a bit.
It's not quite as romantic as just knowing where to go would be, but that's life.
-----
By the time you've arrived at the Matou residence, the sun is starting to go down. Nervously looking around for signs of magecraft, you don't spot anything that could be dangerous. Oh, there's plenty of bounded fields, obvious familiars, and expensive-looking granite statues around, but nothing that would kill you, so long as you're careful.
You make your way down the front walk, gravel crunching under your feet. Capitalist follows, his cane marking a fairly nervous tap-tap on the ground behind you. Somewhat hesitantly, you knock on the front door.
Nobody answers the door at first. All of the familiars on the manor, in the forms of worms, hummingbirds, koi, and at least a few shrikes inch closer to you. A minute of awkward waiting later, an old, wrinkly man answers the door.
"Who is it?" he demands. "I want you damn kids off my lawn!"
"I'm---"
[ ] Write in a name
"--and I heard your lawn is off limits to kids," you continue, silently gesturing for Capitalist to step closer to you in case the old man attacks. He doesn't look too threatening right now, but you know this is one of the most storied magus families in the world you're dealing with right now. Better not to take any chance. "You prefer keeping them in your basement."
The old man's eyes narrow, and you notice all of the familiars getting even closer to you. You continue, "I know about Sakura Tohsaka. If word of what you're doing to her got out, things could get ugly."
"Are you threatening me, foolish girl?" Zouken growls. "I'm the greatest familiar magus in the last millenium, and you're a stripling with a Servant in a vessel more unstable than the Einzbern servant in the Third War. I could consume you--"
"I'm not threatening you, sir. Instead, I have a proposition for you," you say, snapping your fingers. Capitalist conjures a small mound of bills. "As you can no doubt tell, my servant may not have a chance at winning the War, but he can create limitless amounts of currency. And my family is in the market for an heir as well, given my...lack of suitability in that regard. We would be willing to offer you any amount of money you ask in exchange for the girl."
Zouken just stares at you for a moment, the various familiars around the garden skittering around. Finally, he says, "Get out. Be grateful I'm letting you leave here with your life."
You try to interrupt, to get in another offer, but Zouken slams the door behind him, and you hear several mundane and magical locks clicking shut.
[ ] Attempt to get Zouken Matou to reconsider his decision.
-[ ] Have Capitalist crush something with money.
--[ ] A statue.
--[ ] A single room.
--[x] The entire house (BAD END 1)
-[ ] Write in
[ ] You don't think Zouken Matou will budge for money. It's time to get someone else involved.
-[ ] Attempt to contact the civilian police. Surely Fuyuki City has some form of child protective service.
-[ ] Attempt to contact another Master or Servant. You're confident that at least one magus will find Zouken's behavior repulsive.
-[ ] Attempt to contact the Magus Association. You wouldn't want one of the founders of the Holy Grail War to give all magi a bad name if his activities are discovered. Better to handle this quietly.
[ ] You tried, but you weren't successful. It's time to focus on preparing for the actual Grail War.
-[ ] Find a location to use as a home base. Capitalist can buy you whatever land and buildings you need.
--[ ] (write in location characteristics)
-[ ] Attempt to surveil other Masters and Servants to discover their identities.
-[ ] Ask your own Servant about his identity.
