currently liking this series, it is so far, opposite of most of the mecha wherein, protagonist pilot uses an OP machine to kill grunts easily regardless of the pilot's skill set. Then later on he will face the enemy's ace and either the protagonist wins or survives it. (currently, argevollen is already dropped due to the following reason)
So far so good, I am not currently bothered why our hero is so calm and collected even when his friends are dying or in danger. As for the mecha design, I think they look generic but at least they look more realistic.
