Is it possible to get the Red Bandana after missing it the first time?

See title. I missed it in my first playthrough in the year 0 section and it’s the only item I’m missing, I’ve gotten likely every power gem otherwise and 7 death coins, and hit the level 13 soft cap. Gonna really bug me if I’m unable to get it on this save and have that be the only thing it’s missing

You can go back only if you didn't get any more of the other light being color Soul Weapons. Katana is fine to obtain.

You will be sent back to the beginning of the game then and be able to open the chest.

You'll have to wait for a save editor.
