Sound of the Sky - Season 1 (2010)

Kanata struggles to improve her bugle skills when practice doesn't seem to help. Meanwhile, Noel tries to make a replacement lens for the optical sensor.

Kanata, Kureha, and Noel travel to a location in the wilderness that's along the border of No Man's Land to investigate three ancient surveillance devices. The task seems simple enough until the group finds out their hike will be more difficult than they imagined.

It's a bright, sunny day, and Kanata has received her first paycheck! Meanwhile Mishio and the rest of the platoon run into problems when the Mafia comes to Seize.

Second Lieutenant Filicia is usually bright and cheerful but there's a part of her past that haunts her. As summer reaches its hazy peak, memories of her old platoon keep resurfacing, along with visions of their terrible fate.

Kanata happily volunteers for phone duty to prove her worth to the team but she soon discovers staying in one spot is harder than it sounds.

The rainy season arrives in Seize and a typhoon is on the way. Unfortunately Kureha is preoccupied with Claus, the Desert Wolf hero of the 481st Platoon!

Old Lady Jacott has lived in the mountains for most of her life. She's always been able to take care of herself but now her health is failing, and winter is coming. Rio agrees to help the old woman but soon learns lessons that only Jacott can teach her.

The peace talks between Helvetia and Rome have ended in disagreement and there are rumors of Roman troops on the move. Meanwhile, Kanata and Kureha find a Roman scout lying injured in the snow.

The Demon of Vingt is ready to spark another war and the women of the 1121st Platoon are outnumbered and overwhelmed. Luckily, they use their courage and the sound of the sky for hope.
