Basically they took the starting point from the end of the first season of Infinite Stratos and OVA… and just started writing their own story based around harem hikinks. There’s some very small bits of the original plot up through episode 5. Mostly, it’s just stupid. Episode 5… really stupid. After four episodes of BS, they’re sort of trying to rejoin the threads of the original plot. Seriously, if you don’t have any interest in the picture below the fold, episodes 1-5 aren’t for you. Although Tatenishi (not shown) is pretty cute.
Just what is this, aside from a variant ED? Show ▼
Once again, Charl is made of win and awesome.
In any case, I hope the nonsense is through, and they stick to the novels after this.
