Digital Encyclopedia

[Sakuraluna]

Because, let's be honest here, the digital Version would be pirated to a ridiculous amount, kinda invalidating all the work put into it.

I'm sure that any version of the encyclopedia that offers an in-game item code would be more sought-after than any other, pirated or not. But an official digital version would give players who can't easily get their hands on the physical version an option other than pirating.
