This manhwa feels like prolog to second seson and having 78 chapters as prolog is too much. But story line as whole is
mysterious and interesting also main characters are interesting so why is it so bad? Well are is terrible for example
there are no details or in one picture some characters have they hair on their back when their fac is facing fron and on second one when theire face is facing to a sied the hair is stil on theire back.
For some reson this manhwa has just too much side characters as part of main character group and there is no way you can remember all of them if you reading it for first time also it feel like autor is using them as pokemons
(if team needs to fly out of nowhere a guy shows up ho can fly).
I recomend trying to get trough first seson becose next one is much better as art story and powerlevel goes up.
Basicly everything gets much better. (review of second seson will be in second seson part)
