Discard event items?

Is it safe to discard legendary yo-kai medals and other event items after the event has ended? My inventory is clogged with these.

Thanks!

You can if you want, but... seeing as the event already came back twice, it might come again so you might want to save the medals if you didn't get everything last time.

keep them they will probably bring it back again at next expansion a ploy to make players do lower level fates with lower level people

Thanks, everyone. I'll keep them for next time.
