World Trigger

When a gate to another world suddenly opens on Earth, Mikado City is invaded by strange creatures known as "Neighbors," malicious beings impervious to traditional weaponry. In response to their arrival, an organization called the Border Defense Agency has been established to combat the Neighbor menace through special weapons called "Triggers." Even though several years have passed after the gate first opened, Neighbors are still a threat and members of Border remain on guard to ensure the safety of the planet.

Despite this delicate situation, members-in-training, such as Osamu Mikumo, are not permitted to use their Triggers outside of headquarters. But when the mysterious new student in his class is dragged into a forbidden area by bullies, they are attacked by Neighbors, and Osamu has no choice but to do what he believes is right. Much to his surprise, however, the transfer student Yuuma Kuga makes short work of the aliens, revealing that he is a humanoid Neighbor in disguise.

World Trigger is more than a decade old now (its first 73 episodes are from 2014, the second series came in 2021 and the third series came in 2022) and it is still brilliantly fresh. Firstly, it has a story that is generic as can be: there are exoplanetary attackers on a Japanese city, some Earth forces called Border based on that city defend the planet against these invaders called the “Neighbours.” The main character Osamu Mikumo, his protégée Chika, his Neighbour friend Yūma Kuga become part of the Border and fight against the Neighbour attacks along with many other brilliant supporting characters who surprisingly ... have depth.
The series is well written, the visuals are above-average especially for the period, there are several episodes that end in such a cliffhanger that you automatically continue to another episode, the characters are well written, in-depth, and as there are quite a few episodes, there is room for every supporting character to have their own side-stories. The music is alright, and that they have the opening credits in the 10 to 12 minutes mark instead of in the very beginning is a nice detail and the opening credits change every 24 episodes. In addition to battles, competition, and a look into self-growth the series also has a great angle over friendship and solidarity.
I highly recommend this series.

Mixed Feelings

60-SECOND REVIEWS

This one's a bit of a mixed bag of mixed quality. I loved the strategy in the fights and the intricate world building, which between the world and the game-like, rule-following fights they have throughout the show, reminded me of Hunter x Hunter. Unfortunately, the adaptation itself often confuses what is actually happening on screen.

This may also be the single cheapest looking shounen I've seen in years. Flat and choppy, and the sequels only slightly improve on this.

Toei Animation makes weak adaptations of great sources--just take a look at large portions of their One Piece adaptation or how drawn out Dragon Ball Z ... was--and this series deserved much better. There are great, fantastic moments sprinkled throughout, which only serve to give a glimpse of how great this material could have been in better hands.

It's hard to give this one a full skip, because the way tactics are integrated into the numerous fight scenes, each one filled with strategy and clever decision-making, each fight treated like its own puzzle to solve. Your mileage with the characters will vary. I liked a few of them, but there is a huge cast of side characters who have very little to set them all apart, so outside the central characters, it's all pretty bland.

First of all I hate animes that does a freaking long review of the entire series, instead of just the most reason development, I mean if you haven't watch the series from the beginning then it doesn't matter either way cause this is a freaking long anime. That said can't believe why so many positive reviews of 8s and 9s seriously.

This anime has such terrible main cast, 2/3 were useless from the beginning. The main guy tries to improve himself throughout the series and we're force to follow his boring non-progressive development for almost the entire time. The worse part is the MC received ... help from many of the top rank guys but still remained as useless as if he never had any training. Can't rant anymore without spoiling too much regarding the plot.

Bottom line is only watch this crap if you have nothing better to do. Even then I think there are way better animes to watch then this, or if you like the kind of idiot that is weak as hell but sprout about how he wants to be a hero and safe everyone but accomplish absolutely nothing besides talk, this is for you.
