Nagisa Ichigaulait
sandiNagisa from Mix Ore. To describe her with anything more than "Strawberry Milk" is a pretty massive spoiler, so you should just check out the game if you haven't already. It's a quick read, and especially enjoyable for those into tragedy, horror, or yandere characters.
Nagisa Ichigaulait and Mix Ore are both property of Charon, and not me, so be sure to credit them and not me if using this model.
