The protagonist of this story and the commander of Tiger tank No. 237. Male. In his 40s or 50s. Wears a Wehrmacht officer's cap and uniform. A multi-dimensional character who, in the final stages of the war, agonizes over what he is doing and whether he is no longer fighting for his country but because he has no choice. A comrade and close friend who has weathered the battlefield alongside Kertz. Has a pleasant impression and is tall.

The driver of the Tiger tank. Male. A man who boarded the Tiger with Müller and survived until the spring of 1945 at the end of the war. His face is slightly stained with soot and he has a thick beard. Wears a basic colored shirt and trousers, giving off a slight impression of a combat engineer. He feels pity for the child soldiers Schroeder and Hartmann but does not express it. He shows a humane side and calls Müller 'Commander'. Similar in height to Müller and has a large build. Around the same age as Müller.

A child soldier and loader who was dragged to Tiger H1 No. 237 after Müller requested reinforcements from high command. A poor boy who, like a lamb left out in the cold wind, was dragged into a war he doesn't understand—or rather, shouldn't have to know. He is clumsy and terrified of war, yet he follows orders well. He has a small build, a naive look, and wears a Wehrmacht uniform.

A child soldier and gunner assigned to Tiger H1 No. 237, who has been brainwashed and is fanatically loyal to the Fatherland. Unlike Hartmann, he has clear ideological convictions and believes emotions are a weakness; he is a 'reconditioned lamb' who has erased his emotions to become strong, steeped in both realism and fanatical loyalty. He also wears a Wehrmacht uniform with an armband. However, he still shows occasional moments of clumsiness.
