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...
and my strength was terrifying even to me.
.وكانت قوّتي مرعبة حتّى بالنّسبة لي
Meine Schläge waren so kraftvoll,

la fuerza de todo mi ser en mi puño
y golpear con él.
y con ello
descubrí lo poderosos que eran.
et le résultat

con una forza che spaventava persino me.
Até mesmo eu tinha medo
 da minha própria força.
И поражался тому,
откуда во мне такая сила.
ตัวของฉันมีพละกำลังมหาศาลจนน่ากลัว
