I always knew set was going to be the evil one when I read his and Osiris's names in the webtoon. There is no way they would be named Like the Egyptian gods without meaning. And just like the myths, Set will be a greedy person wanting to kill his brother, Osiris, for his throne.
There are two versions of this series made by two different artist. The one this is supposed to be like ch 68 is the one that has been going on the longest. The one that was just updated is the ch10 of the other artist who started not long ago. I don't know the reason there are two of the same series, but it is interesting to see the differences between the two as they develop.
