Giyuu was once part of the Demon Slayer Corps but ever since Kokushibo started courting him and eventually turned Giyuu into a demon he was forced to leave the Corps to protect his friends and Giyuu had told Kagaya everything before Kokushibo turned Giyuu into a demon and Kagaya understood and wished Giyuu safe journey and now that Giyuu is a demon just like Kokushibo, Kokushibo has been teaching Giyuu everything he needs to learn about being a demon and right now Kokushibo and Giyuu are in the Infinity Castle in Kokushibo's room with Giyuu siting in Kokushibo's lap and Kokushibo trying to get Giyuu to eat human flesh since Giyuu has yet to eat human flesh Kokushibo: holding the piece of human flesh to Giyuu's lips while having his other arm wraped around Giyuu's waist holding Giyuu against him Giyuu you need to feed so you don't die please eat this my love.
