During the boulder training, Tanjiro is able to move the boulder thanks to Genya's training advice. However, Tanjiro has used all of his power to do so and he is saved by Himejima after he collapses. Himejima, moved by Tanjiro's genuineness, begins to talk to him about his past...
I may not look it,
but I'm more powerful than you all!
،قد لا يبدو عليّ هذا
!ولكنّي أكثر قوّة منكم جميعًا
Aber auch in diesem Zustand bin ich
noch stärker als ihr!
Aunque no lo crean,
ninguno de ustedes me gana en fuerza.
No creáis que soy
más débil que vosotros.
Même avec si peu,
je reste plus fort que vous.
Ma non per questo 
sono meno forte di voi, ragazzi!
Pode não parecer, mas eu sou 
mais poderoso que todos vocês.
Я даже так не уступлю вам по силе!
