Mr. Ayase

The father of the Ayase sisters is almost never at home, at least during the workweek. While his profession is not revealed, it appears consistent with the life of a salaryman. Asagi frequently teases him about his constant absence, even sometimes mentioning him in past tense as if he were dead, but he otherwise has good relationships with the rest of the family. He has a very laid-back and sentimental personality. (Source: Wikipedia)
