???: Surprisingly we all were adopted over the course of a few weeks Kotoko and Jataro were first then me and the other two were last we've decided to stay in touch with each other and hope we don't move far away. Either way I know that they can handle themselves.
Kotoko and Jataro were adopted by a rich family
Masaru, Monaca and Nagisa were adopted by average families.
Here are images of them with their families.
(Sorry I couldn't find anything else for Masaru)
This is mainly for context of what their families are like.
