I am playing the story "Hapilly ever after" with hideyoshi. Can you still get him? I completed kenshin's story so what should I do now?
Just got Mewtwo today. I made the Floating Stone thing level 3, the Mine level 3, and the Snow Mountain thing level 3 (all of these in Illusio, of course). He showed up the very next month, but I read on here that it is random after that point. Did it in Hideyoshi's story.
