Futsal Boys!!!!! follows Haru Yamato, who has never had an interest in futsal before but after watching Japanese player Tokinari Tennoji compete at the U-18 World Cup, prompts him to join the high school futsal club. The typical underdog story is a premise familiar to sports anime, a rookie joining a new club with a veteran player to begin a journey of competing against established teams. However, Futsal Boys!!!!! fails to deliver on this hype as our core cast of characters gets minimal build-up in terms of development, remaining at a surface level with little exploration of their motivations or deep thoughts. In addition, no one throughout the anime mentions soccer, which is usually how most people get into playing futsal in the first place, illustrating the lack of effort put into developing character motivation giving the audience little reason to be invested in our leading team. The hype was there for a gripping sports anime, but the flat characters have left Futsal Boys!!!!! fans disappointed.

The art has not helped Futsal Boys!!!!! with the graphics for the anime showcasing a colourful cast of characters, but when it comes to the animation and fluidity of futsal being played, it's clear no references to actual futsal were made. Technically, the animation and art are fine for a sports anime, never reaching the heights of a series like Free but not being jarring to put the audience off the anime. However, the lack of technicality renders the action scenes, the pinnacle of sports anime, dull and uninteresting. This means Futsal Boys!!!!! has a cast that the fans can’t get invested in because they lack development and action scenes that lack finesse in comparison to the energy of the characters, causing the anime to fall flat on all fronts.
