Feature Highlight: The Ultimate Scanner vs. The Absolute God

: The episode dives into Kojiro Sasaki's unique history. Unlike other heroes, Kojiro never won a single duel in his life. Instead, he surrendered whenever he knew he was outmatched, only to spend months—or even years—mentally replaying the fight until he could defeat his opponent in his mind.

In ( Shuumatsu no Walküre ), Episode 10 of the first season is titled "Greatest Loser" . This pivotal episode shifts the focus to the Third Round of the tournament, featuring the clash between the "God of the Sea," Poseidon , and the "Greatest Loser" in history, Kojiro Sasaki .

: Fans often note that Episode 10 features some of the most consistent animation in the first season, particularly during the sequences where Poseidon dodges Kojiro's signature move, the Tsubame Gaeshi .

: While previous fighters like Adam relied on direct replication, Kojiro uses "Scanning." In the episode, we see him sit perfectly still before the fight even begins, having already died thousands of times in his mental simulations of Poseidon's first move.

: For the first time in the series, a god refuses to even acknowledge their human opponent. Poseidon enters the arena with absolute disdain, whistling a haunting tune and refusing to look Kojiro in the eye until the samurai actually manages to graze him.
