Fourteen-year-old Kouichi Hayase's life has always been a mediocre one, if not dismal. However, those days of being bullied by classmates and escaping to a fantasy of being a hero are put to an end when a certain "accident" bestows on him a girl and a gigantic humanoid robot called "LINEBARREL." The extraordinary power that Kouichi obtains puts him and everything around him on a sudden rollercoaster ride of battles, intrigues and friendship! During the course of his adventure, the boy starts to learn what life has to offer; he meets new friends, bids farewell to the old ones, but most of all he now has considerable responsibilities and is forced to confront the world around him.

tl;dr: A mech anime with a pretty great character arc for the protagonist but that is lacking in most everything else.

This anime is one that’s greatest strength, it’s protagonist, started out seeming like it’s greatest weakness.

What makes this anime unique is that unlike most anime with similar premises where the protagonist is just luckily inherently heroic and capable of acting as such, Kouichi is anything but. He starts off incredibly self-centered and immature, wherein even ...

Overall I'd rate Kurogane no Linebarrels 6 out of 10. There were numerous basic ideas lined out, but no major, developments occurred further on.

Review may contain minor spoilers, but nothing that will affect viewability of the show. (KnL = Kurogane no Linebarrels)

First off, the art used in this series was good. Nothing outstanding, but no shortcuts seemed to be taken. Every aspect from characters, through environments and special effects were easy to understand and I personally had no problems seeing what any of the displayed aspects were.

Preliminary (2/24 eps)
This show is just horrible. The MC is so poorly done that I am horrified I even gave 3 minutes of my time as he kill's any enjoyment of the show.

One part he is literally yelling his name out then when another pilot in a different calls out his name he gets confused on how she knew his name. Meanwhile as he is yelling he is Justice he is slaughtering people. The artwork and sound was passable and the story might have ...
