Dayakka Littner hails from Littner Village, sharing his origins with Yoko Littner. When their village was destroyed, the survivors moved closer to the surface only to face relentless Beastmen attacks. This forced Dayakka to evolve from village mayor into a guerrilla leader, defending his community where his leadership and unshakeable composure proved vital for their survival.

He joined Team Dai-Gurren, initially piloting a Gunmen before passing it to Kiyoh Bachika. Dayakka then shifted his focus, serving as a combat coordinator and bridge operator on the Dai-Gurren battleship. He stepped into the role of acting captain during Simon's absences, his calm and responsible nature providing essential balance against more impulsive teammates.

Seven years after the Spiral King's defeat, Dayakka married Kiyoh Bachika. They welcomed a baby daughter, noted during the Kamina City celebrations. When the Anti-Spiral threat emerged, Dayakka participated in the confrontation, piloting the Space Dayakkaiser in pursuit of the enemy.
