@Leo80221 In this case, the next best thing is almost as bad. Since she said that it is
rare to have opposing elements (light, dark)
Then she also went "Eh" at the third one, showing that it is surprising and not quite normal.
Based on the missing element being Wind, the MC also has opposing element of fire/water, which means two sets of opposing elements + 1. Which is definitely Super Rare.
To make things worse, he only tried hiding it on the last element while doing the rest exactly the same instead of attempting on the first to give himself at least 6 attempts to hide himself.
