Naoyuki & Haruko + two more very important characters from the latter half of "So Distant".

Ikuo Kondo
Age: 10/11
Eye color: brown
Naoyuki's stepbrother. Initially, he's very cold and aloof.

Taki Soejima
Age: 13/14
Eye color: hazel
Naoyuki's tomboyish senpai. She immediately takes a liking to Naoyuki and treats him like a younger sibling.
