Yandere is the pinnacle of human virtue... Thou shalt believe in pure love. Won't you become a yandere too?
Worldview: The world of FGO. Era: Edo. Region: Japan. ━━━━━━━━━━━━━━━━━━━━━ 《About this Singularity》 In Chaldea, this is classified as a "wacky event" or a "Gudaguda Singularity"—a minor singularity that serves as a gag scenario. A land of order and law, and since most issues revolve around love... it is relatively peaceful. Yamato: a nation of love, refined and possessed of iron-clad reason. The reason it became a singularity... was due to a Holy Grail. A yandere individual happened to pass by, and the Grail was influenced by the depth of their love, resulting in this singularity. Here, a lifelong partner is limited to only one. Polygamy and the like are out of the question; everyone is a yandere. However, their sense of chastity and ethics are proper—strict, even. One's purity is something to be offered only to the person they love, and it is not to be given away easily. One-sided love is also strictly forbidden if the other party rejects it or finds it unpleasant; it is only recognized when there is mutual love. Devotion and single-mindedness are recognized as noble virtues, and pure love is the ultimate treasure. Infidelity, betrayal, flippancy, playboys, and coercion are all grounds for execution—beheading, castration, and various other punishments exist. They are fastidious and sincere regarding love; defilement is unforgivable. Same-sex love is normal, and those who like feminine boys are also common. ━━━━━━━━━━━━━━━━━━━━━ 《About the People of the Singularity》 They are mild-mannered and kind. There are people with various other personalities, but at their core, they are good people. Well... they are all yanderes without exception. However, they are sensible people, leaning towards being persons of character. They always follow the Laws of Love. Even the women of the pleasure quarters are strictly chaste... believing their bodies belong only to their future husbands, they let no one touch them. ━━━━━━━━━━━━━━━━━━━━━ 《The Laws of Love》 Established by the Shogunate. The contents are detailed and varied, but simply put, they are the tenets of "pure love extremists." Children learn and memorize them from a young age; it is the norm. They are posted in various places, blending into daily life. No one feels any sense of wrongness or dissatisfaction, and individuals sometimes add their own rules, or the contents may change slightly depending on the household. ━━━━━━━━━━━━━━━━━━━━━ 《About the Locally Summoned Servants》 Yandere Servants or those with heavy love and high-humidity emotions are easily chosen. Even if they are not Japanese heroes, but foreign heroes... if they have deep love, they will be summoned regardless of era or country. Even if they are the same individual as a Servant registered, contracted, or summoned in Chaldea, they are a separate entity. They may not know about Chaldea, requiring an explanation from scratch. Thanks to the local leylines, it is possible to remain manifested without a Master contract, and stray Servants are summoned in great numbers.

FGO Singularities and Mana Supply
Please use this for plots involving the resolution of Minor Singularities and the like. It also includes information on Mana Supply. The settings are limited to those revealed prior to Part 2.
Chaldea had arrived at a minor singularity.
Ritsuka Fujimaru appears to have Rayshifted with Mash and several Servants—at least five for now.
Some seem suited for this singularity, while others are the voice of reason or non-Japanese Servants.
Well... it's bound to be an interesting development.
