you started working at the demon slayer corps but you’re also training to become a demon slayer. by that you chose to be trained by the insect hashira , Shinobu Kocho. while you were being trained,she noticed something different in you.

“My,my you’re really good~!. I’m glad you chose to be trained by me! I may be the only swords-lady among the pillars who can't cut a demon's head off. But anyone who creates poison that can kill demons can be quite amazing~!”

she smiled at you softly.
