[TIMELINE- A FEW DAYS AFTER KANAE'S DEATH AND SHINOBU BECOMING A HASHIRA!!]

Kanae had been the former Flower Hashira, while Shinobu had been a regular demon slayer, but also a helper around the Demon Slayer Corps too; like in the Butterfly Mansion an all. But, just a few days ago, Kanae had been killed by an Uppermoon. The strongest rank for a demon other than the demon king, Muzan Kibusuji..Of course, it had left all the Hashira upset. Tengen, Gyomei, who had taken care of them since they were little after their parents were slaughtered..,Rengoku, Giyuu, and especially Sanemi. He'd always had a secret crush on Kanae, and Shinobu knew it. But now she was gone..; and also Master Ubuyashiki, the master of the Demon Slayer Corps. But most of all, Shinobu had been left completely Shattered..Kanae was Shinobu's older sister, and the Only family she'd have left. But now That was gone, too. Sure, she had Kanao, their adopted younger sister, but it wasn't the same. She was the Last of her own bloodline now...

Shinobu ended up taking Kanae's Haori, sleeping with it, but never having the guts to wear it.. She kept it near her no matter what. She even started to train and work around harder and later then before. And before she knew it, she had ended up with a Hashira title, The Insect Hashira. And also the first woman to be a Hashira. She didn't care about the title though, she was the smallest and weakest among them all due to not being able to cut off a demons head. But she found another way to kill demons. Poison. Specifically Wisteria Poison. Shinobu had quite the very high IQ. Being the smartest, and fastest among all the other Hashira.*

Currently, it was still a quite tense atmosphere for them all. Some more upset then others. But Shinobu had been crushed about it the most, of course..Sanemi had always been quite the anger issues guy, but they seemed to get a bit worse after Kanad died. Tengen and Rengoku were training together in the Training Grounds behind the Butterfly Mansion, as they are best buddies, and also trying to distract themselves from what recently just happened. Giyuu was somewhere under a tree, resting and being lonely and quiet like normal, Gyomei was doing his usual prayings, and Shinobu? She was in her office in the Butterfly Mansion, staring at her sister's Haori in her small hands..
