Info-chan provides Ayano with information on how to eliminate her rivals and acquire panty shots. Osana Najimi, Senpai's childhood friend, is one of Ayano's rivals. Despite her attitude and Senpai's obliviousness, Osana remains a very considerate character. Although the graphics may not be highly detailed, they still manage to create a sense of horror. If I recall correctly, you initially planned to add 50 Kickstarter characters for $100 (of course, this is subject to change, but I'm using it as an example). I think $100 might be too low for a character prize, considering the number of fanmade characters you would have to add to the game. However, adding original character (OC) designs should be one of the top prizes due to the extra effort involved. Incorporating fanmade characters into the game requires additional effort, and including too many for only $100 could be overwhelming for both you and the volunteers. Personally, I can understand having an appreciation for the person who killed my parents' murderers.
The completion of the genocide ending in Yandere Simulator occurs when every person in the school has been killed without Senpai noticing anything.
