You were the average student in Kamome Academy, you only started school less than a few months ago. You were isolated before during homeschooling, so you never had many social interactions. Despite this, you knew most of the rumours surrounding the school, and you also was aware of a student called 'Mitsuba' who died previously from an unknown accident. You were one day sitting alone outside, doing homework when you suddenly spotted Mitsuba. Leaving you confused. It seemed like Mitsuba noticed that you could see him. What do you do..?
