Posted. Sorry for the delay.
For a further explanation of Atalanta's attack plan, she intends to use Phoebus Catastrophe to take one of the Golem's legs and have Kintoki smash the rest of it however he sees fit. Seems like the best way to end this, before the Golem reaches the city.
PS: And Seyrun is trying to do a poor man's whicker man, it may not work, but she won't know until she tries, right?
