Cursed Class (An Another Story)

In the town of Yomiyama, Japan, in 1972 there was a popular student named Misaki. When Miksaki died halfway through the year, the class was devastated, and out of grief, they continued on as though Miksaki was still alive. Then in the graduation photo, Misaki appeared. Ever since 1972, one dead person who doesn't know they are dead has shown up in Class 3-3. In order to make up for this, they pretend a person doesn't exist.
It is now the year 2000. A new school year is in session. Yuri Umeki is in the dreaded Class 3-3.
All that he can hope is that he will make it through the year.
