reading chap 14-17, my bet is, towards the end of the series, reiji will migrate to himelda's home country and become next in line to the throne or something and have everybody join his harem.....
but this could be wrong...... but what will rei? chan do to be included, or is she like a matron deity to them then.....? i dunnoo....
number wise, there's currently 6 + rei girls? in the group... just nice for one per day....
