Defeating the Hard opponent in 701 within five rounds (Haruka's Trust) - Yakuza 3 Remastered
Among the hardest tasks required to 100% complete Yakuza 3, this is probably the easiest. One of the five requests Haruka makes when you reach rank SSS involves defeating the Hard opponent in 701 within five rounds.
This isn't easy, but it's very manageable if you know what you're doing. First of all I'd like to thank "kirbo" on Steam for his in-depth guide about Haruka's Trust. I suggest you read it if you're interested.
Here's the link: https://steamcommunity.com/sharedfiles/filedetails/?id=2955373408
He's also made a video (linked inside the guide itself) where he covers the same topic.
Another useful guide is this one (https://steamcommunity.com/sharedfiles/filedetails/?id=2385420586), which covers throws that allow you to consistently get triple 20 (the highest possible points per throw) or bullseye.
Now, about the challenge itself: the mode in which you have to play this is a 01 game, so the rules of that mode apply. What you want to do is to get as many points as you can in as few rounds as possible. If you follow the guide linked above, you'll understand how I managed to get all those triple 20s. Do not pay too much attention to the opponent, as your real opponent is the number of rounds you have. Once you get to 41 (assuming you landed only triple 20s up to this point) you can speed up things by landing a double 20 and a 1. I decided to land two separate single 20s, as the number of rounds wouldn't have changed and I didn't want to risk losing aat the end. All in all, this is doable without too much effort. Good luck to you if you're attempting this!
