Ayano's Father

'''Yandere-chan's father is the husband of Ryoba Aishi. His real name is currently unknown.'''

''Note: His name will eventually be revealed in-game. The name will not be spoiled on Twitter. ''

He will be a character in 1980s Mode as a student attending Akademi High. He and his wife are out of the country for ten weeks in Story Mode because his wife is chasing down The Journalist, as stated in Basement Tape #10.

Background
When Yandere-chan's parents were in Akademi High in the 1980s, her father was Ryoba Aishi's  senpai. Yandere-chan's mother killed the Phantom Girl with a knife in the third floor girls' bathroom because the Phantom Girl liked him.

The father has a job related to the game's lore. YandereDev has planned to drop hints about what the job is soon.

Personality
He seems to be a normal person. He is never said to love his wife, even after they were married. He lampshades this in Basement Tape 10.

Appearance
Not much is known about his appearance except that he looks like an adult version of default Senpai.

Ryoba Aishi

Ryoba is devoted to Yandere-chan's father, but he does not truly love Ryoba in return. The father heard about what The Journalist said about his wife. She kidnapped him against his will and held him hostage in her basement. They got married and had one daughter, Yandere-chan.

Even after having a daughter, the father is still afraid of his wife. For example, when he thinks he has accidentally said something wrong about their extremely quiet daughter, he quickly corrects himself before Ryoba can notice, implying that he still doesn't love her and fears her after all those years.

However, he finally has come to love her and even desired to start a family with her.

Yandere-chan

 * Main Article: Yandere-chan

Yandere-chan feels indifferent to both her parents. The father suspects Yandere-chan to be emotionless or just strange, but he does not know his daughter's true nature. He's also a little creeped out and worries about her, but he still loves his daughter. This is supported in Basement Tape #10, since he is concerned about Yandere-chan's well-being about her living alone. Nothing would make the father happier than learning that his daughter is a "normal" girl.

If the father sees Yandere-chan trying to romance a female Senpai, he might have a positive reaction, because it would be like seeing the end of the Aishi bloodline, which wouldn't be a bad thing in his eyes. It was originally planned that he would strongly discourage the relationship. His values come from Japanese society, where same-sex relationships are considered to be a social taboo by many. If Yandere-chan was in a hetero-relationship with a male Senpai, the father would worry about the nature of the relationship, and how it began.
