SMH is not a normal high school neither was it a normal prestigious high school, it was a cursed school. A school with students disappearing cases, there were no answers, there were not even questions. Nobody knows what the hell was going on. The dead can't say anything neither can the missing say anything. The mystery remains unsolved year by years.

However, people only know SMH...

SMH is a prestigious high school with strict requirements. Talents all over the world gathered here to study. Moreover, most famous artists, scientists, inventors, the great detective Sherlock Holmes, unidentified serial killer Jack the Ripper and even the infamous escape artist; Jyugo, et cetera, they all graduate from SMH. To admit into SMH, they not only have to be in the top 15% for the admission examinations but also be in the top 20% of the national examination as well then go through strict interviews. Besides that, school fees are extraordinarily expensive, 99.8% of students come from a wealthy family and only 0.02% of the whole school cohort study in this school with a scholarship, earned from their talents.

However, the weird thing is that an infamous rumour that spread like a fire inside the school have never, never been spread outside. 

And the rumour is.. that some students from the first year, second year, or the third year, would disappear on the same day, and that doesn't only happen once, not twice, not thrice, but four times already.

SMH has no fixed name, just SMH but people wonders, could the S means 'Spiritual'? or the M stands 'Mystery'? or the H is the initial for 'Horror'? No one knows what the person who came up with this name was thinking, no one has a single clue.

SMH is founded since 1913.

People say the school appeared on the empty lot only after one night. But no one can prove that because of the lack of technology and evidence back then.

The first case happened on the 4th of May 1933, followed by the second case, on the 4th of May 1953. The third case also happened on 4th May, in the year 1973. Similarly, the next case is on 4th May 1993. By the 4th case, a total of 34 students has been reported missing and never found.

As predicted after every 20 years, on the 4th of May 2013, something similar will be happening again, the 5th case.

Until the 4th of May 2013, no one had solved the puzzle, even the smartest man in the world can't piece any of the puzzle pieces together.

However this very special year, the selected ones were all from the first year elite class, with their combined effort even the toughest nut can be cracked.
