There's another logical anomaly that I forgot to mention yesterday.

How can Tacchan and the other Muggles enter the AA @ 14:54, while the gate into the AA can only be opened by alchemists? It's already established since episode 1 @ 05:48 where Rinne who was being followed by Houtarou opened the gate to the AA by performing the alchemist chant, and shortly after it Houtarou (who was still a Muggle at that time) attempted to enter the gate but he failed because it was automatically closed after a person passed through it. So, the best thing that Tacchan and the other Muggles should only be able to do in this episode is wait outside of the gate and then ambush the AA members when they come out of the gate. Does this logical anomaly suggest that Houtarou/Rinne/Spanner/Sabimaru/Renge/Minato are so dumb that they leave the gate open that enables strangers to casually enter the AA? Don't know!

The scene in episode 1 @ 06:35 where Houtarou attempted to enter the gate to the AA:
