If SE wanted to do another yokai event i would rather want SE to team up with level-5 for a mass collaboration for something with white knight chronicles ( a game i feel needs more love in the west) they could hold rewards focusing on level-5's main game lines

as for the yokai event we have had twice now, no it is very outdated and not very liked, plus SE wouldn't be the ones to give the go ahead since level-5 would need to agree to it.
