During Chapter 6 after you return to Ijincho, approach the little girl to the left of the main doors at Seiryo High School to obtain the Squirrels Just Wanna Have Fun side case. Press R3 to examine the squirrel then select “Listening carefully”. Press L3 then select the Noise Amp to examine the wall light to the right of the squirrel near the rail. You’ll receive the Superstitious Eater’s Guide, which unlocks the Auspicious Gourmet skill, and the case will close.
Please note that there are 56 squirrels total!! It’s time to begin the hunt! Go nuts 😉 For a guide on the locations of these squirrels, click here!!
