Event Year: 2014

A large strike force encounters an enemy unit that takes them by surprise; Nagate does what he can to protect his friends.

Pacifists endanger themselves by leaving the relative safety of Sidonia, while the enemy shows up larger and fiercer than before.

The Gauna find a distressing way to demoralize and out-fight the attack force. Nagate returns to Sidonia with a prize that may help in the fight.

Nagate is blamed for a defeat and harbors guilt over a casualty; the early years of Sidonia are revealed.
