Attack on Titan has some of the most emotionally intense moments in anime history, and Yuki Kaji, the voice behind Eren Yeager, gave everything he had to bring those scenes to life. During the recording of 'Hero,' one of the most impactful episodes in Season 3, Kaji pushed himself so hard that he actually fainted in the booth.
As the voice of Eren, Kaji had to express extreme emotions, from anger to desperation, especially in scenes where Eren is fighting for survival. The weight of those performances took a toll on him physically, showing just how much effort voice actors put into their craft.
Attack on Titan Scene That Pushed Yuki Kaji To His Limits

The 'Hero' episode was a turning point in Attack on Titan, featuring one of the most powerful battles between the Survey Corps and the Beast Titan. Eren had to inspire his comrades while dealing with overwhelming odds. Kaji’s voicework had to reflect not just Eren’s rage, but also his pain, frustration, and determination.
During an interview, Kaji revealed that he pushed his voice to the limit, screaming with such intensity that he lost consciousness for a moment. The emotional weight of the scene, combined with the strain of delivering Eren’s lines with full force, caused him to collapse. The staff around him had to make sure he was okay before he continued recording.
Not The First Time Yuki Kaji Has Shown His Dedication

This wasn’t the first time Yuki Kaji gave his all for Attack on Titan. Throughout the series, he consistently delivered performances that made Eren’s journey feel real and raw. From Eren’s early days as a vengeful young soldier to his later, more conflicted self, Kaji poured his heart into every scene.
Many fans and fellow voice actors admire Kaji’s dedication. His ability to bring Eren to life with such emotional depth is one of the reasons Attack on Titan has left such a strong impact on viewers worldwide. His fainting incident is just proof of how seriously he takes his work and how much he respects the story he’s helping to tell.
