Black heart probably refers to that boobie girl's earings. This chapter was like, a direct timeskip just after the GMG-eclipse arc. It's like everything that happened in Tartaros Arc can be ignored and go straight to here specially to those who plan to catch up to the manga. That's just my opinion. I have a feeling Hiro will give flashbacks for the sake of remembering past events. Don't get me wrong, I don't hate it. Minerva's outfit is sooo cool and sexy. That backless style matches her transition to being more lady like. Sting looks same, I prefer Yukino's more serious side. And Rogue, how I wish he got an outfit that would show his guild mark(they're twin DS) but oh well.
