Spend a ton of money on the prostitutes in Ys. (looks like 10k coins or 10 good times)
Simply give 1000 coins prostitute or give 1000 coins athlete to have a good time. 😉
They will disappear after you pay them, so it will take multiple runs through to get the whois.
Note: you should be paying them even if you don't want the whois! They give you a 30 minute hpr prep!
