In Persona 3 Reload, Elizabeth tasks you with bringing her Chilled Taiyaki, which can be tricky to obtain.
Where to find Chilled Taiyaki in Persona 3 Reload
You can’t buy Chilled Taiyaki directly. First, purchase Lukewarm Taiyaki from Club Escapade in Paulownia Mall after reaching Courage rank two.
Once Junpei mentions a Suspicious Man selling URLs at the club, buy the School X Site Note URL from him. Access the URL on the dorm computer to unlock Lukewarm Taiyaki.
The School Store Vendor at Gekkoukan High School will then sell Lukewarm Taiyaki. Buy one and freeze it in the dorm kitchen. Ensure there’s space in the freezer, as it might be full initially.
Return the next day to find Chilled Taiyaki in the freezer. Give it to Elizabeth whenever convenient. It’s not the last request from her, but timing can be tricky.
