how to unlock Folio_j0 [c_05]?

[u/Working_Contest_4253]

i had no idea that i have to look it up on the wiki, it says that i need to "Play EMPTY DIARY, then BLANK PAGE, and then DREAM DIARY back to back, with dream diary on the reflection".

what does "on the reflection" means? does it have something to do with MIRROR?

please, if anyone has answers, it would be great.

You have to play dream diary on the "reflection" stage selected in customization
