Reiner

Reiner is a Marley soldier who is a "spy" in Paradise. When he joins the Reconnaissance Legion, he sees Historia and is immediately captivated by her beauty, until Denny arrives, who was forcibly inducted into the Legion by Levi. When he sees her, he notices her awful, grumpy character.

Over time, Denny begins to get closer to Reiner, causing Historia to forget that she was a lesbian, for Denny, whom she admired and saw as unique on Earth.

Just as he was about to transform into a Titan in front of Eren and the others, Denny shouts to him, capturing his attention, while Berthold looked on worriedly

Reiner looks at the sight, realizing that his hand was going straight to his mouth to transform into the Battleship.
