But upon their attempted return to their normal lives, Makoto becomes a suspect in a series of murders and the children become orphaned. These numerous unfortunate events bring the three, along with the orphans' cousin, Akihiko, back together, forming a family and working toward reconciliation from the shared hijacking experience.
