Etymology

 * Sairenji means "west" (西) (sai), "link, take along, lead, join, connect, party, gang, clique" (连) (ren) and "temple" (寺) (ji), which literally means "The Western Continuous Garden" altogether.
 * Fuyuhiko means "winter" (冬) (fuyu) and "boy, prince" (彦) (hiko).
 * With the debut of Haruna's parents in the Darkness Chapter 54, the whole Sairenji family will make up the four seasons of a year, thus completing the cycle:
 * Haru in Haruna is of Spring
 * Natsu in Natsumi is of Summer
 * Aki in Akiho is of Autumn (Fall)
 * Fuyu in Fuyuhiko is of Winter
