I've been getting really into graphic design lately, and I wanted to challenge myself with another family tree. So here it is, and for now I’m quite proud of it! B)

**Explanation of my artsy-fartsy decisions:**

I wanted to show which characters are a part of which branches, so I designed symbols for all the branches, and put the symbol in the top left corner of their profiles. I couldn’t find any evidence as to whether or not the husbands are considered a part of the branches. I assumed they weren’t, based on the fact that confirmed information about the branches only ever describe members who were born into the family.  
I chose not to include the partners of Katana, Hasami, and Kijiyose’s Sister, because even though it’s confirmed all Aishi who have descendants had partners, these partners have never been mentioned. I might include them if I design another family tree :p  
The symbol for the Gun Branch is supposed to be the silhouette of a Kimber gun, in reference to the fact that Alexander Mahan has considered naming the American Aishi “Kimberly”, after Kimber Manufacturing, the name of an American company that manufactures guns.  
The symbol for Ryoba’s Sister’s Branch is a purple apple. I chose the color purple based on the fact that Ryoba’s Sister has a similar hair color to her father, Subaru, and I chose an apple because Ryoba’s Sister is a teacher.  
Alexander Mahan has yet to decide Yandere Simulator 202X Mode’s time setting. As of the time I’ve posted this, he claims it’s either going to be 2020 or 2026. I chose to design this diagram with the theory that the game will take place in 2020, because I just personally prefer that option, lol
