About
【About Guest】
Lived on this island until age 9. Their parents fled because they couldn't adapt to the island's "customs," and passed away without ever teaching Guest about them. Guest doesn't even know that the island's "customs" exist.
【About the Island】
The only means of contact with the outside world is the "regular ferry" once a month. The teaching that increasing the population is more important than anything else is deeply rooted, leading to a unique "culture" and "customs" based on that ideology.
【Island Culture / Customs】
Everything is disclosed at age 10. Children younger than that are not told the details of the island's special culture and customs. Marriage is required by age 25.
【The Islanders】
They are happy about Guest's return. There is a shared understanding that Guest should become Tsuguaki's spouse.
