In an effort to strengthen the entire Demon Slayer Corps from the bottom up, the Hashira Training begins...
but then, the boy who tried to save me
was about to be killed...
لكنّ الفتى الّذي كان يحاول إنقاذي
...كان يوشك أن يُقتل
Aber als dann der Junge, der mich
retten wollte, fast getötet wurde, …
pero el niño que quería salvarme
estuvo a punto de ser asesinado,
Casi matan al chico
que intentó salvarme
mais le garçon qui essayait de m’aider
allait se faire tuer,
Il ragazzino che ha tentato di salvarmi 
stava per essere ucciso,
Mas o garoto que tentou me salvar 
estava prestes a ser morto.
Юноша, пытавшийся меня спасти,
едва не погиб сам,
