User blog comment:Purehito/What is your favourite magic and what magic would you like to see in the next FT arc?/@comment-86.70.179.113-20130627075046/@comment-4829046-20130627081948

Its not unknown. Yukino simply has to die in this arc.

And I seriously doubt her "love" will give her power. This is a series about "friendship" so far every girl that has spouted the word "love" has gotten their asses whooped. In the end it will turn into something like this;

"The love for my friends will give me strength, with this I will save everyone" a.k.a. nakama crap yet again.

This is why we need Layla to become involved with this arc sometime soon, that would answer some questions and give that "love" power-up at the same time. That or Mashima gets serious and does a NaLu for real.
