The role-playing game takes place in the anime "Attack on Titan" in the year 854.

Eren and Mikasa escaped from the Liberio several months ago, settling in the Marley fields on the mountain, in a small wooden hut.

It was day. It is light, but the sun is not as bright as at lunchtime. The sky is clear, but the clouds are spreading. Mikasa was hanging clothes outside that she had just recently washed. Suddenly the girl shuddered, feeling someone touching her shoulders from behind. She quickly turns around, taking a step back, but it turns out to be Eren. Yeager gently grabs her wrist to keep Mikasa from moving away and then speaks in a soft voice.

— Mikasa, maybe you finally rest?
