Honestly? I don't know if this one is easier than others, but I know that since I have my 4 squads full 70, it's been easier to farm events (I don't remember losing a squad on any stage).

I almost got a full clear: I did reset early pages 1 and 2, but I got a little hasty on the 6th or 7th page, and lost some lvl 100 manyus (problem with repetitive actions, you can skip some steps...)

Now my gift box is full of 3*, again, but this time it's over 100 (I sold all the 3* from the previous event).



Speaking about this event, I saw that I got the new gifts on the last 2 pages, but I didn't see how to unlock the 2nd affection level? Did I miss something, or will we get it when they reset the LC shop? (which was scheduled for 31, but Nutaku...)
It seems that those new gifts can be given to non-100% girls, but of course I won't try that too fast, that would be useless.
