|My friends got killed, yet I didn't feel any sadness or hate at all! Deep down, I just felt glad it wasn't me!|
|— Daz admits his cowardice|
Daz has a short crop of spiky gray-colored hair and light brown eyes. He wears the normal uniform of the 104th Cadet Corps with a black shirt underneath.
Daz is constantly terrified, regardless of the situation he has an ever present fear of something bad soon to happen, and when it does happen he loses complete control and often complies with dying by sword over facing Titans again.
At some point during training, the cadets of the 104th Cadet Corps complete a snowstorm training exercise, arriving at a base at the foot of a mountain. During the exercise, Daz loses consciousness due to overexertion and Christa and Ymir are forced to pull him along on a cot.
After deducing that Christa has no intention of returning to base alive with Daz, Ymir leads her to a cliff overlooking the base at the foot of the mountain and throws her aside into a snowbank. Ymir then utilizes her Titan powers to quickly return Daz to the base.
When Christa eventually arrives, she asks about Daz, and Ymir shows her that Daz is safe indoors.
In the year 848, Reiner is placed in a group of cadets led by Thomas Wagner to go on a wilderness hunt that will teach the cadets to sustain themselves in times of peace. Daz is the first in his group to notice when their ODM gear goes missing. Determining that their gear must have been stolen, the group decides to speed up their mission to warn the other group of cadets on the mission about the thieves.
The next day, Daz and his group come upon Marco's group, who have been engaging the kidnappers, and help them disarm the remaining men.
Inside the Walls, Daz is one of the soldiers put on standby. He tells Marco that he is unable to fight anymore, as his comrades were devoured right in front of him while he was just happy not to end up like them. Knowing that he might be the next one to die, he takes out his sword in an attempt to commit suicide, but Marco stops him.
As the soldiers are gathered together so Dot Pyxis can inform them of the plan to reconquer Trost District, Daz begins to panic and starts screaming that he does not want to die. Though Marco tries to quiet him, a commanding officer overhears and threatens to execute him for abandoning his duty. Daz invites him to, claiming that execution would be preferable to being eaten by a Titan.
Pyxis announces that the military will use Eren Jaeger's Titan ability to reseal Wall Rose, but Daz accuses the commander of lying, and reiterates his intent to leave, refusing to give up his life. However, Pyxis' reminder that all potential deserters will be abandoning their families to the Titans convinces Daz to return to participate in the operation, unable to leave his family to such a fate.
He is an unexceptional member of the 104th, but skilled (or lucky) enough to have survived multiple encounters with Titans.
