Six people per square meter? Wut? I know they live cramped in Japan but seriously... maybe the translation should say six square meters per person? That would make more sense (still that's a humongous house).
Lots of hate for this. As a loner with a bad temper I feel he is too nice. As a loner, he should just give them his house and go make a new one in a superior loner area.
He's in the middle of the a forest with possible hostiles around, and it takes that to get his attention?
@Saxit I believe he is answering the question of how many 'can fit', not how many could stay there at once. At which point, we are talking about cramming people in there standing room only like an elevator, and then 6/m^2 makes sense.
It does mean it will be really crowded when he tries to fit the ~15 girls in there.
