World Trigger is shounen series mix with some sci-fi elements and its kinda work.

[Story]
Earth is under attack by different dimensional alien monsters. That all you need to know and it's a good set up, a lot of room for the creator to plexes his imagination. Plus open goal for the story to move freely on its own pages and perfect for a long epic war story.

[Art]
the alien monsters and the setting are beautifully drawn but the characters design is the biggest reason why I dropped this manga. They are drawn in simplistic designs, meaning the lack of expression and it's terrible. It's something likes this:
Normal scene: stupid faces
Life and death combat: the same stupid faces !!!
I mean it's just so frustrating to see the same F***king faces on every F***king characters at every F***king moment.

[Character]
I have nothing again the characters, they're fine. Nothing to hate but also nothing to like.

[Super Power]
What I like about shounen are the creative ways they used super power.
And World Trigger really know how to use its power system. From what I see, everything it's very balanced, every match wins by skill and experience. Plus the main cast progress at a reasonable rate and no bullshit power buffs.

[Enjoyment]
The terrible art alone kills the entire experience for me. But if it doesn't bother you then I completely recommend reading its.
