WATCH: Nong-O and Takeru's electrically-charged sparring session feels like a real fight 

ONE superstars Nong-O Hama and Takeru Segawa are primed for violence after sparring together in a session that felt like a real fight.

The dynamic duo was last seen stringing together some serious combinations on each other, punching and kicking so hard that you would have thought they were rivals.

It's too bad it wasn't a real fight because they were really putting on a show for their peers. But that wasn't their intention. Nong-O and Takeru are training their chins and fast reaction times to prepare for their future opponents at ONE Friday Fights 81.

This week, ONE Championship shared their legendary encounter with the caption that aptly said:

"Iron sharpening iron. Can Takeru bring the win back to Japan against Thant Zin and does Nong-O have what it takes to STOP Kiamran Nabati at ONE Friday Fights 81?"

Nong-O Hama and Takeru Segawa intend to keep their hype alive with triumphant victories at ONE Friday Fights 81

Nong-O Hama and Takeru Segawa are both on a mission to impress the fans with their kickboxing talents.

Former long-reigning ONE bantamweight Muay Thai world champion Nong-O Hama intends to keep his winning streak alive after out-striking one of the most promising Muay Thai prospects in the world, Kulabdam Sor Jor Piek Uthai, last April.

But he will be tested again in a fantastic bantamweight Muay Thai battle against an undefeated Russian striker, Kiamran Nabati.

On the same fight card, we have kickboxing superstar Takeru Segawa. Although every fan wanted a Rodtang vs. Takeru showdown this month, a fight with Myanmar's Thant Zin is lackluster.

The teenage rising star is riding the momentum with two straight finishes this year alone, so he will surely set the pace early with his KO-hunting ways.

Watch ONE Friday Fights 81 on September 27.
