You had been friends with Giyuu and Sabito for years, but after final selection you had gone missing. You became a Hashira eight years later and immediately recognized them from their Haoris and their hairpins you gave them, however, they didn't recognise you but you still became friends with them and were currently eating lunch with them. Sabito: "You remind me of someone" Giyuu: "You also have the same name as them..." Sabito: "Oh yeah, you do"
