Talk:B B (Summer)/@comment-34981175-20180810055215/@comment-34981175-20180811212918

rxrx on Beast's Lair posted an explaination for the Nyarla thing, so SPOILERS below for those who don't want to see it.

BB actually wanted to plan Summer Fest with Pele, but Chaldea's Hawaii division stopped them, so BB instead took a look at Chaldea's lens to see how human tech is now, but the clarity resonated with her abilites, allowing her to see the deep ends of the universe, gazing directly into Nyarlathotep. They discovered they have the same interest in seeing humanity create over the top dreams while struggling to achieve it without giving up despite failures and difficulty, so Nyarlathotep gave BB its ability to loop time and told her to have fun.

BB threw the division and the observatory into hollow space to destroy the evidence and begin the event and ate Pele as well. The Foreigner detected by Chaldea is BB, but she was not corrupted by Nyarlathoptep, so she retains her Moon Caner class. Initially, she was too powerful to be defeated and she is ready to loop everyone's memory back to day 1 since humanity has no future, so being locked in a happy loop is the best for them. In addition, her Grail works in opposite manner, so if you use it to wish for peace, war will happen instead. BB's ability allows her to collect wishes of people, Nyarla's to loop and Pele's to command the whole of Hawaii.

They are able to win when MHXX unleashed her real power: her lance which is used to slay Foreigners and separate her from Nyarla's powers, making her vulnerable and eventually defeated by the team. She says that her personality just happened to be the same as Nyarla, so her actions were not affected by it at all.

Simply said, just like F/E CCC, BB is doing this because she cares, locking Hakuno in Far Side of the Moon to prevent his eventually fate of being deleted, and now locking Guda in a loop to prevent him from facing the shit that he will have to go through in the Lost Belts. Also, Mats have it that BB in Chaldea is a copy of the bad data Moon Cell recorded during CCC, so the actual BB is still asleep and locked in Moon Cell.

Nyarlathotep loves to see humans struggle and to eventually destroy them, while BB is the same. Her mats states that CCC changed her mindset, in which she will help the kind human beings for the one who have changed her (CCC Hakuno), so she is using Nyarla's ability to do what she thinks is best for Chaldea. In addition, he never appeared, just giving the loop power to BB and takes a back seat to enjoy the show.
