The Heartbreaking Truth Behind Tamayo's Vengeance Revealed in the Final Episode of Demon Slayer: Hashira Training Arc

The reason why the demon Tamayo (voiced by Maaya Sakamoto) burns with a desire for revenge against Muzan Kibutsuji (voiced by Toshihiko Seki) is... In the final episode of the anime "Demon Slayer: Hashira Training Arc," Tamayo's heart-wrenching past was revealed.

In Episode 8, which marks the final episode of the Hashira Training Arc, Kagaya Ubuyashiki (voiced by Toshiyuki Morikawa), the leader of the Demon Slayer Corps, blew up his own mansion, including himself, in order to defeat Muzan. Furthermore, Tamayo used Blood Demon Art to restrain Muzan’s freedom and injected a medicine into his body that would turn demons back into humans. Muzan declared, "You truly are a persistent woman, Tamayo. Your grudge is ridiculous. Who killed your husband and child? Was it me? No, it was none other than you yourself. You devoured them," he stated coldly. In response, Tamayo tearfully pleaded, "If I had known that, I would never have become a demon... I said I didn’t want to die of illness because I wanted to see my child grow up!"

When Muzan pressed further by saying, "After that you killed many other humans too, or was that an illusion I saw? To me, it looked like you were happily eating humans," Tamayo replied, "Yes! I became reckless and killed so many! In order to atone for that sin, I will die here along with you!"

Tamayo has continued her persistent research on demons in order to defeat Muzan. Now that her painful past has come to light, online voices have responded with comments such as, "Her overwhelming determination, resolve, and tears," "The reason she desperately wanted her wish, enough to become a demon, is too heartbreaking," "Lady Tamayo’s tears, her feelings—they’re beautiful," and "Lady Tamayo’s scene is so painful."
