Here you can find links to all of the walkthroughs for Radiant Tale (official Japanese website | Nintendo Switch product page).
The game has a total of 11 endings to acquire:
🎪 2 endings for Zafora
🎪 2 endings for Paschalia
🎪 2 endings for Ion
🎪 2 endings for Radie
🎪 2 endings for Vilio
🎪 1 common ending
My recommended play order is as follows:
Zafora | Paschalia | Ion > Radie > Vilio
(the common ending can be played whenever)
At the start of the game, only Vilio’s route is locked. You’ll have to complete an ending for each of the other four love interests before you can play his route. Aside from Vilio, there’s no real spoiler danger from the other routes but I would suggest leaving Radie until second-to-last. Of course, if you’re really interested in Radie, nothing’s stopping you from playing his route first. You can find the common route ending under its own “Common ending” post because I didn’t want to dictate when you should play it, it’s completely up to you *(੭*ˊᵕˋ)੭*ଘ
Note that from your second playthrough onwards, you can skip the prologue if you want.
