Yakuza Kiwami 2

To do this, you will likely need to farm some EXP. I found this Reddit post from Reddit user ric_joe that indicates some of the better EXP farming restaurants in Sotenbori: https://www.reddit.com/r/yakuzagames/comments/9ddhf8/kiwami_...

I found I needed yellow (Spirit) EXP, so I went to Sotenbori's Kani Douraku and ate there, using the following strategy.

The full farming EXP strategy is:
* Increase your hunger gauge (in life skills) as much as possible
* Increase your digestion (in life skills) as much as possible
* Buy as much AppStim Half/AppStim RX as you can
* Eat the set that gives you the EXP you want
* Use the AppStims to empty your stomach
* Repeat those two until out of AppStims

This will give you a ton of EXP, but can cost some money. I ended up farming this in Premium Adventure (post-game) and had quite a lot of money (24 million yen), which is definitely suggested.
