[JP] SE.RA.PH. Guide somewhere?

I know the site is 99,9999% focused on NA content, so, is any of you aware of somewhere I can find a guide similar to what we have in this site?
This is the first time I'm going fully blind into an event and it being in Japanese doesn't help either (I blame this site for their absurdly good guides >.<) .I know the event is relatively straightforward, completing the missions to advance in the story, like Zero and Prisma Codes (which I was able to complete last month because I played it already in NA).
