Yuno Gasai activates "Dimensional Manipulation: Omniverse Annihilation" and creates a massive black hole that sucks in everything in its path. Saitama tries to punch his way out, but Yuno amplifies the gravity and crushes him into a singularity.
Saitama counters with "Serious Series: Serious Table Flip" and flips the entire battlefield, including Yuno, upside down. Yuno uses "Time-Space Manipulation: Cosmic Reversal" and reverses the effect, causing Saitama to be thrown into the air.
Saitama retaliates with "Serious Series: Serious Punch of Death" and unleashes a devastating punch towards Yuno. Yuno stops time using "Chronokinesis: Eternal Stasis" and dodges the attack.
In desperation, Saitama unleashes "Serious Series: Serious Table Flip x100" and causes a massive shockwave that demolishes everything in its path. Yuno counters with "Reality Warping: Absolute Destruction" and erases the shockwave from existence.
Final Strike: Yuno ends the battle by using "Causality Manipulation: Ultimate Death" and erases Saitama from existence itself. Yuno emerges victorious from the fight.
