Kaihe is a high school student who has been given the task of becoming the chairperson for St Luminous, a private religious school for girls, after his grandfather died. Kaihe, along with a friend, arrives at the school to take care of business. But soon, mysterious disappearances start to happen. Will he unravel the mystery of the school and its past before its too late?
Ihrie and Fam are just two of the many explorers searching ruins for something called the 'ultimate power'. With the 'ultimate power' the owner has the ability to have any wish granted. Of course all the explorers have different motives for finding this relic, ranging from revenge on a curse-casting mentor, to saving a kingdom from utter destruction.
Trying to find the ultimate power and not actually knowing what it is until the last 10 minutes of the series in Ruin Explorers is very similar to how Luminous doesn't give away the mystery behind the disappearances. These are also quite comical which is always a plus.
