Another (The Sorceror from Tokyo)

In class 3-3 during the year 1972, there was a student named Misaki Yomiyama. He was a charming student with good looks, and he excelled in both academics and sports. All the teachers and students alike admired him.
Halfway through the school year, he died in a house fire that took the lives of his whole family. Unable to accept his death, some of his classmates decided to continue acting as if he was still alive (talking with his desk, pretending to go home with him, etc). This behavior caught on, and at graduation, the principal even arranged to have Misaki's seat included in the ceremony.
After graduation, when the class photo was taken, they found that Misaki was included, with a pale face but smiling like everyone else.
Over time, the oral history of 1972 became garbled, and people could no longer remember how he died or even whether he was a boy or a girl.
following these events, the class grew closer to death itself.
A Sorceror named Satoru Yotsuba from Osaka, Tokyo came to Yomiyama North Middle School as a transfer student since his previous school was demolished by the Goverment due to it taking up too much space for other buildings. Satoru was placed in Class 3-3, where the Calamity was set. Will Satoru survive the Calamity? Or will he put an end to it permanently?
