Story (may include spoilers, read at own risk):
World Trigger starts off as your normal "aliens invading Earth" story, but proves it self not to be. However, as we learn about the invaders (called Neighbors), we learn that they're so much more, and with the revelation of several Neighbor worlds, a story is set up since our protagonists are going to face it. While it goes into softer parts, especially during training, when the protagonists go to the other worlds, there will be lots of suspense; the invasion arc proved it.
Art:
Oh man, the art is amazing and fits a sci-fi setting. Each character, Trigger, and background is drawn with so much detail that you can virtually see the characters moving in battle. And the colour pages are extremely appealing, anime worthy.
Character (spoilers, read at own risk):
While not World Trigger's biggest point, it certainly deserves to be acknowledged. An example of character development in the series would be Osamu. He is one of the few shonen protagonists who are weak and work hard for their strength. On top of that, he has strength in other forms like mental resilience and intelligence, which Ashihara cleverly uses. Another example of this would be Chika's high strength but low battle ability.
Overall, I have enjoyed the story very much and can see it becoming very successful if Ashihara keeps up his unique and interesting way of storytelling and showing.
