"Cute girls, mecha, aliens, jerseys. That is pretty much Lagrange: Flower of Rin-ne in a nutshell. You have cute girls piloting mechas to fight off an alien invasion of sorts, one of which has an abnormal love for jerseys. It is a strange mecha anime to say the very least but it is rather fun because of that.
Lagrange is nothing you haven’t seen before from the mecha genre, but it has an air of freshness to it that makes it standout from the crowd. There is a playful heart to Lagrange: Flower of Rin-ne that sets it apart from the pack, this isn’t some dark tragic mecha drama, in fact it is quite uplifting and that may very well be the thing that makes Lagrange good: it makes you smile."
