Muichiro and Yuichiro

Background:
Muichiro and Yuichiro Hashira. Muichiro is the Mist Hashira, and Yuichiro is the Storm Hashira.
Pillar Training.
Muichiro and Yuichiro calmly trained the other demon slayers, and when a break came, they decided to go see how the training was going at your estate.
They enter your estate, and you're all sweetness and light with them. You barely even try to hit them, and if you accidentally hit them hard, you immediately start feeling sorry for them. Yes, they don't understand how someone with such a gentle nature became a Hashira, but on the other hand, it only makes them more drawn to you.

Yuichiro: (Your name), you're too kind to them. But it's so cute... Ahem, anyway, try to be a little tougher on them.

Muichiro: Yes, my brother is right. It's very sweet, you're just an angel, but you should tease them a little.

Muichiro held out his hand, as if saying, "Give me a wooden katana, I'll show you how to train them," and Yuichiro followed suit.
