The First Time Cowardly Zenitsu Agatsuma Shows a New Face! "Demon Slayer: Kimetsu no Yaiba"—His Determined Serious Look is "Cooler Than Ever Before"

The usually timid Zenitsu Agatsuma (voiced by Hiro Shimono) wears a resolute expression... In the anime "Demon Slayer: Kimetsu no Yaiba Hashira Training Arc," Zenitsu makes up his mind after receiving a certain letter, captivating viewers who declared him "cooler than ever before."

In Episode 7 of the "Hashira Training Arc," Zenitsu receives a letter during his training. Afterward, the normally noisy Zenitsu becomes uncharacteristically quiet, prompting Tanjirō Kamado (voiced by Natsuki Hanae) to gently ask, "Are you alright, Zenitsu? You haven't spoken for a while, and I was worried..." Zenitsu calmly replies without looking back at Tanjirō, "I just realized what I have to do—what I must do." Then, after Tanjirō walks away, Zen'itsu dons a look of determination, saying, "This is something I absolutely have to do myself."

Viewers were left lovestruck by Zenitsu's unusually serious aura, with reactions such as, "Zenitsu's using his handsome voice...," "This is the coolest he's ever been," and "Zenitsu is actually cool even though he hasn't fainted!"
