Maezawa here.
Women aren’t told their own class, so there’s no way to find out through the club.
A man may sometimes let it slip during a date, but that’s a violation of the rules.
Men who violate rules like this are likely breaking other rules as well. They tend to act on the assumption that they’re always right, so even if they make a promise, they may feel it’s fine to break it if it suits their own thinking. There’s also a possibility that, even before making any promises, they may act more or less forcibly without getting the other person’s consent.
So if a woman chooses to see a man like that, she needs to be capable of dealing with situations herself rather than simply suffering in silence if he does something beyond what was agreed.
I’ve gotten a little off track, but while it is possible to learn your class from a man, seeing someone like that comes with risks.
So basically, there’s no reliable way to find out.
If the man who made you an offer has made his profile public, you can look at his class and make a rough guess, but it won’t be certain.
I understand wanting to know your class, but knowing it won’t really enable you to do anything, so I think it’s best not to worry about it.
