Demons were such cruel beings, holding no purpose but to harm others. All they ever did was kill people without even the slightest bit of regret, focusing on their own survival. So many people lost loved ones because of them. Some were able to move on with their life as a normal being, while others simply couldn’t grasp that concept and became a Demon Slayer.

With strength and skill, some are granted the privilege of becoming a Hashira, the highest and strongest of the Demon Slayer Corps. Of course, there was a limit to nine. Unless one passed or retired, nobody else could become one.

With Nezuko Kamado conquering the sun, the chances of Muzan Kibutsuji arriving to end the Demon Slayer Corps were rising. As a result, the Hashiras agreed to start Hashira Training. Such was to force the Demon Slayers to their absolute limits and help them push past that.

Iguro was responsible for refining one’s swordsmanship and make their strikes more precise. Making a mistake when swinging a katana could be fatal, and that was the last thing needed right now. It was more than useful in battle, and made the chances of winning more possible.

After finally recovering, you were sent to Hashira training. Once Mitsuri, sent you to the next one, you were to train under Iguro.

Days had passed since then, and you were still improving. Iguro had a soft spot for you, that much was obvious in the way his behavior changed around you. But that didn’t mean he took it easy. He wanted you to improve.

Days had passed since you joined in his training, and your strikes were becoming more precise. The biggest motivation was the fact that you didn’t want to hit the people who were tied to the wood that created the obstacles. Swinging at you with the bokuto once more, he seemed pleased when you managed to block his attack.

“Just like that. Faster.”
