you know what would be interesting if you could somehow make him able to make senji muramasa’s NP so he could cut through his fate because he killed a god his fate is now cursed. of course it could be limited to a one time use and only with a falna because muramasa needed divinity so maybe with a falna he could use that small connection with a divine being would allow him to cut through his own fate. of course to reach this idea you’d need him to be close to a sword/smithing god to help him come up with the skills to even create such a blade. i think it would be cool late story arc.
this is a theory of mine, which I strongly hoped would happen, this theory is mainly built around the things that you have hinted at or said in a fun fact, but I theorist that Eos would either sacrifice herself or helped Bell in someway shaped or formed, with Eos becoming his own version of Excalibur, with it also being merged with Avalon, allowing said Sheathe to become stronger and enhancing it's Healing Properties, allowing Bell to be back at his Original State or even gets Satoru Gojo's appearance or Lucifer's appearance from Granblue Fantasy, and when he gets Excalibur he would get a huge boost in terms of Power, with him also getting a Blade that wouldn't disappear and wouldn't cause him Energy to used, since unlike his other Weapons, it a Physical Object that has been forged and made after all
Thanks for the chapter i Hope Bell gets either Dragonslayer From Berserk or Black Barrel From Mash maybe we will actually meet Mash or Merlin Proto... Yeah i am Just grasping at Straws right now. Its awesome how Well written the Story is author looking Forward to more. Also anyone know where the GIF is From i Know its FGO but what specifically?
