Anniversary character might not be evil...

Last year's Half Anniversary and Anniversary were evil. Assuming the Half Anniversary and Anniversary have the same personality, this year's Half Anniversary was good, which leads to the hypothesis that the Anniversary might also be good. However, I built an evil party to match Yuzu, and set the masked character's personality to evil too. If the Anniversary turns out to be an overwhelmingly good-performing character and suddenly creates a good environment, I'm going to lose it.
