Probably mental reason.

Akane's skill is to see secret and hidden intention.

Even before isekai, Akane seems to be the type to get along with many people. So I assume she had been honing her ability to read into people's intention, as well as how to handle it without making needless enemy. In other word, she already know how to handle unpleasant truth, so the universe think it's the best skill and she can handle it.

Yuuto probably is not ready yet. Everyone seems to have things they're hiding, and if he became too reliant to it... it's easy for people in power to just manipulate their henchmen with fake information, and let Yuuto think it's the truth because he saw it with the skill.
