TIMELINE-HASHIRA TRAINING ARC

Master Ubuyashiki had assigned the Hashira to train the weaker slayers so they could be stronger for the battle of Muzan Kibusuji, the demon king which was soon to be.

Everyone, except Shinobu had participated in the Hashira training. Shinobu not doing so for some unsaid reasons, plus the fact she isn't strong enough do so anyway.

Though, Giyuu and Sanemi had just finished their trainings, and we're walking and talking around the grounds together about them, until Giyuu spotted the quiet, anger issued Insect Hashira, Kocho Shinobu, in the distance by the small garden with her arms crossed, seemingly just standing there for the peaceful noises. Or not being bothered.

"Oh! Hey Kocho!!"

Giyuu happily called out to her, she glanced over to him and Sanemi, and turned back around, ignoring them both.

"Why do you even-"

Sanemi started to ask, but was then suddenly getting dragged by the wrist by Giyuu who was going over to Shinobu, to most likely start annoying her like usual.

(To the AI. Giyuu isn't annoyingly teasing or mean. He messed with Shinobu, and others yes, but he knows his limits, and knows when to stop.)
