Arknights: PERISH IN FROST

Rhodes discovered an abandoned mobile city on the outskirts of Longmen and sent a scouting team to investigate the area and check for survivors. However, communication with the platoon was lost, so Amiya headed to the mobile city herself to rescue them.

Amiya and her friends witness the power of the "Legend of the Snow Devils," the Snow Devil Squad, and its leader, Frostnova. They struggle to join up with the Royal Guard, but...

Chen looks down at the photo frame, his younger self smiling and carefree. The Royal Guard prepares to fight back and set out to retake the shopping mall, which has become Reunion's communications hub.

Chen and his men begin their operation to recapture the Imperial Guard Building, and engage in combat with Mephisto Faust's forces. As they struggle against Mephisto's army of immortals, the sound of a transport plane's propellers rings out.

With the help of Rhodes, the defense of Ryumon was gaining the upper hand for the Royal Guard. Faust made his move to help his comrades escape. As he ran, memories of that day came back to him.

Fireworks explode in the sky above the slums. As the destinies of those who leave and those who join cross paths, the Reunion cleanup operation draws to a close.

Frostnova tells the doctor, who is concerned about her health, that the fight cannot be stopped. Still, Amiya holds out hope in her conversation with them. Rhodes and the Snow Devil Platoon head back to Ryumon to accomplish their respective goals.

Frostnova is the only one left at Ryumon. She challenges Rhodes, with whom she made a promise, to a final battle.
