Yet another Manhwa with lots of promise that gets cancelled.
Now, I'm not trying to scare you away from reading XO Sisters because it's not finished, but the fact that it was cancelled affected my enjoyment and my opinion about it. Certainly, it is not easy to review an unfinished Manhwa but I will try my best.
Storywise, XO Sisters falls into the countless generic Mangas/Manhwas that have the MC and his/her companions fight against monsters from another realm whilst the general population of the world are unaware of them. This overused plot depends on many genres like comedy or romance/harems to try and stand out from the others, and surprisingly, the story itself is what draws the reader, not the romance(if there was any ??) or the comedy.
Already the summary in MAL does a very poor job to describe the setting and story behind it. Obviously the MC being mistaken for being gay at an all girls school is not the main plot line. The fantasy elements and the harem are the main twist behind it.
I found the art to be very good. The heroines are beautifully drawn and the action scenes are really engaging. The character's expressions convey really well the moments of comedy and seriousness, but the backgrounds are forgetful overall.
You get a glimpse of what the story will evolve into and you barely scratch any kind of character development before it ends, but the character interactions and the story make up for it. Every heroine has a notable personality, but they too fall into the same stereotypical characters that come with the genre. Glasses to the smart, blonde to the tomboy, you get the idea.
I thought XO Sisters was entertaining. You get to see how the MC deals with his and new life in school and how he manages to get himself into strange situations with his newly formed harem, as well as the action moments that come with it. You are led to believe that the MC's abilities are not natural and that he has some hidden power that will awaken 'a la shounen-esque', but as the plot thickens, the story ends.
Overall a 6/10 okay read if you have an hour or so to waste. You are warned to read at your own risk if you can deal with an incomplete story.
