"We did it, sir."

- Kazuko talking to Mendez after being trapped on Onyx.

"Yes. We all did. Ever, think about settling down?"

- Mendez finally revealing his knowledge between Kazuko and Kelsey.

"Uh... I'm a soldier Mendez, like you. Not really...fit for other things."

- Kazuko trying to deny his feelings.

"Really? I think you'd make a great dad."

- Mendez gazing over toward Kelsey.

Just as every other Spartan-II, he was conscripted into the SPARTAN Program at the age of six in 2517 and underwent numerous augmentation procedures to become the ultimate soldier. He would go on to fight in the Human-Covenant War but then retire with Kelsey-015 who would bear two children that would become heroes in the Alliance-Aldar Empire War.

Training on Reach
We he was abducted, he became friends with notable other Spartans like, John-117, and Jorge-052. However when they were put into teams and began service he rarely saw them. During training he began to have some sort of affection for Kelsey-015 who was second-in-command under him in Ruby Team. But, it was forbidden to show any affection to fellow Spartans as it could send you to the brig or get you discharged.

During the augmentations he was one of the fastest recovering Spartans and accidentally witnessed the death of two of his closest friends Micheal-011 and Nicholas-133. He instantly tried to rush over to help the but was held off by another Spartan who recovered faster than anyone else.

He and Sam were struggling so much that Sam accidentally struck Kazuko and knocked him out. He finally woke up on his bed were he later attended the funeral on the. Sam later apologized to Kazuko after the ceremony, but Kazuko stood silent staring into the void of space, that was the last time Kazuko has ever seen Samuel.
