Yandairy-Chan

Seymour Aishi, also known as Yandairy-Chan, is Yandere-Chan's first cousin, and a resident of the Nihonese Republic of America.

Backstory
Yandairy-Chan gained her love of milk at a very young age. Her mother and father were very distant from her - she was instead raised by her godfather, Todd Howard. One day, while in the offices of Bethesda, she accidentally drank some irradiated milk that Todd was developing for a Fallout 4 ARG in hopes to "outshine Fallout: New Vegas (2010)." The milk was the best thing she ever tasted, as she was being raised on a diet of illegally imported Pocky and Top Ramen beforehand.

Being an Aishi, Seymour is shunned by her family for not being an edgy cunt and having a senpai. However, she instead views it as dairy being the senpai that awakened her to her true emotions.

Personality
Yandairy-Chan is very friendly and open, though childish, immature, and stubborn. Her first instinct is to always be kind to strangers. She respects most opinions, so long as they are not harmful. When it comes to milk, however, that is a different story. If one calls milk "disgusting" in her presence, she will shun them, if not taking violent action against them immediately. However, if she believes they can be enlightened by the ways of milk, she will make it her own personal project to change their opinion. She is stuck in a battle of morals over what to think of lactose-intolerant people.

Her Persona, Devoted to Milk, is a variant of the Devoted Persona. She will do anything for milk. Anything. except for murder, because that's a little too far.

Yandere-Chan
Ever since Yandere-Chan moved out of the Nihonese Republic of America to real Japan, her and Yandairy-Chan fell out of touch. Yandairy-Chan thinks her cousin is weird, because she kills 'n' stuff.

Pip-Boy Aishi
Pip-Boy Aishi is Seymour's mother. Pip-Boy is a crazy psycho edgy asshole, due to being an Aishi. Due to this, Seymour and Pip-Boy never had a real relationship.

Cobblestone Aishi
Cobblestone Aishi is Seymour's father. Due to her mother's possessiveness towards Cobblestone, him and Seymour never had a real relationship.

Ryoba Aishi
Ryoba Aishi is Seymour's aunt. Seymour thinks that she's a crazy bitch. They don't have much of a relationship other than that.

Todd Howard
Todd Howard is Yandairy-Chan's godfather. He was the one who mainly raised her, due to lack of interest or ability from her real parents. Todd is the one who indirectly gave her her love of milk, and also gave her her mentality of "it's not a glitch, it's a feature."
