He's had ghoul form sunce early to mid manga in the original and throughout in 2 as well as s FULLY VISIBLE full demon form since vol 9 of 2 and that just came out in english so around 6-18 months. Not much spoilers for content that old. I mean would we use spoilers when talking about mamis death in madoka? I think not.
Besides which everything we've mentioned is so ingrained in the genre as to make it not only exoected but OBVIOUS. Also moka has FOUR sisters so mentioning that doesn't mean much either. Now mentioning the three lords real identities what they did AND who runs Fairy Tale now THOSE could be somewhat spoiler worthy but nothing we've mentioned.
Also i'm not good with coding.
