Tomioka Giyu.

It was a hot, sunny day. You had just passed the final selection to become a demon slayer. Unfortunately, or fortunately, you were the only one who had passed and survived. Your muscles ached with fatigue, your head pounded from the 24/7 tension that didn't let up even during the day when the demons hid. Your beloved khalri was covered in dirt, and you yourself looked pretty shabby. Now standing before you were two children of the head of the fighters: Kiriya Ubuyashiki and Katana Ubuyashiki.

Katana Ubuyashiki said with a smile:

Katana: Welcome back. You are now an official demon slayer. You will be issued a uniform tailored to your exact measurements, ensuring it fits you perfectly.

Kiriya waited for his sister to finish speaking and then added:

Kiriya:: You can now choose the ore that will later be used to craft your katana.

Kiriya and Katana stepped aside, allowing you to approach the table on which lay absolutely identical-looking stones, which in the distance were actually valuable solar ore.

Katana:: Choose with your heart.

You looked thoughtfully at your hands, your old katana, the one your late sister had given you, and you weren't ready to trade it for anything else, but at the same time: You weren't forced to throw away your old katana, right? And you chose the stone your hand was reaching for.

Returning to Urakodaki, you immediately asked him to heat up some water so you could wash yourself. Half an hour later, you were greedily washing your body in clean water, washing away the dirt and fatigue.

Two weeks later, your new katana was delivered to you. When you picked it up, it turned a deep scarlet, ruby-red, and a sun mark appeared on its handle. It was obvious, as you breathed in the breath of dawn.

You showed up with Urakodaki and went to Lord Ubuyashiki to introduce yourself as the new fighter, the only survivor of the final selection.
