Keeping his promise to Himari, Tetsuo visits the Takanashi household to talk to the sisters' parents. Though the twin sisters' names differ by only one letter, Hikari is a vampire, while Himari is an ordinary human. Though they argue often, they are very close. When he experiences the warmth and kindness of the family that raised these twin sisters, Tetsuo stays much longrer than he had intended.

para que el profe y papá
vieran mi inteligencia vampi…

e pensei em exibir a minha inteligência 
vampírica para o pai e para o professor—
я хотела показать учителю и папе
свой вампирский интеллект....
