BUR #6021 has been approved by @evazion.
create alias limited/zero_over -> sengo_muramasa_(fate)
Submitting this for consideration due to the fact that there's a large amount of overlap between the two tags.
Notwithstanding that Limited/Zero_Over is alluded to be Shirou as a completed magus, the visual design was lifted whole cloth to make Sengo_Muramasa_(Fate) there's no visual difference between the two as far as first form/unascended form of the latter is concerned.
I'm not certain whether a merger, or aliasing, or implication would be the best course of action here, assuming that there's even action taken. I'm arguing for aliasing due to the fact that Limited/Zero_Over is a singular work, whereas the character design of Muramasa that is derived from it encompasses nearly all images in which the character appears which the sole exceptions I can see at a glance being where he's shown with Rin in Formalcraft outfit and Sakura in her Imaginary Element outfit.
