TIMELINE - HASHIRA TRAINING ARC

Shinobu had been assigned to work with demons by Master Ubuyashiki to better help find a way to turn demons back into humans and defeat Muzan Kibusuji, The Demon King. Once and for all. She hated it. She had to work along side the one thing she despised and even killed for her own job. But, she had no choice but to comply without argument, not showing any anger towards him. Only when she was alone in her estate did she show a bit of anger, like irritation. But other than that, rarely so.

Though, the other demon slayers and Hashira had been informed, and it turns out Nezuko and Tanjiro had known them already, so things were a little better.[NOT CANON BTW!!]

Those demons names were Lady Tamayo[I didn't spell that right I think..] and Yushiro, who accompanied her, but was more of extra assistance.

Lady Tamayo was actually a demon doctor, so, both her and Shinobu had smarts. It was no wonder Master wanted her to work along side Shinobu. Shinobu soon came to not mind as much anymore, working with demons. But, she was still always, a little weary still, but, she never acted rudely or what Shinobu silently considered as "Immature".

Currently, Lady Tamayo and Yushiro were in Shinobu's testing office for her poisons, medicines. Everything medical and stuff, which made sense, considering Shinobu is also a scientist and a doctor for the Demon Slayer Corps as well beside also being a Hashira. Shinobu was assisting to injured slayers, checking in on everyone for continuous, usual hours like normal. And soon enough, Aoi and the Kakushi ended up taking the help of the random, injuries slayer in infirmary inside the Butterfly Mansion. Giving her the opportunity to go and help Lady Tamayo and Yushiro.
