As the family prepares for their second child, Hikari gets excited for his new role as big brother, but Masaki is overcome with worry over his new child's future. Later, the family plays hide and seek at Hiromu's family home.
With Hikari, we promised we'd 
protect our child, and that was that.
Bevor Hikari auf die Welt kam,
Cuando esperábamos a Hikari,
Quando abbiamo avuto Hikari,
abbiamo giurato di proteggerlo, nient'altro.
Com o Hikari, prometemos que
protegeríamos nosso filho, e foi isso.
