At 6:30 in the next morning, Leonard and others got up and, after having breakfast, started to get ready and dressed up, especially Joan who even did her makeup for this occasion.
Of course, the reason for wearing makeup wasn't simply for the sake of looking beautiful, but because in Japan, it is a social norm for females to wear makeup on certain important occasions; otherwise, it would be considered disrespectful to others.
Although foreigners may not necessarily have to follow this custom, Joan considered that the organizers could be counted as Leonard's friends, so she chose to adopt the local customs and applied some makeup.
Without a doubt, Joan wasn't very skilled at applying makeup, especially the styles popular in this era. However, for someone like her, simply imitating the makeup tutorials she saw in videos was quite easy.
