Some Error here:
> Yukari Kills him Imaginary Rimuru copy, negates GG and of course yuukari didnt know if Imaginary Rimuru exist,
The firs issue, Yukari's Boundary Manip ios Conceptual Manipulation and occasionally 4-D, it Erase you at the Conceptual level and the Range is Multiversal, if she Erase Conceptually the real Rimuru, all existence related to the Concept of "Rimuru" dissapear since it erased At a Multiversal range, so no clone, plus Rimuru never copied 4-D hax and Conceptual so as long as people don't throw NLf as usual for Rimuru, not gonna work too.
>One of the noteworthy change is Rimuru's has now passive Madness Death Hax from Demon's Haki that can killed in the scale of 150,000 which Yukari doesn't resists
Death Hax come from a madness hax which work on a mind manipulation way which affect you if you don't have resistance above 150.000, Touhou Characters resist Planetary Mindhax, so it's no gonna work
>His stomach which is infinite 4D and negates/absorbs any harm incoming, so your attack should be stronger than Rimuru Absorption to one shot him from outside of Imaginary space
Firstly, the size of the realm isn't relevant in this case, her erasure is Conceptual 4-D and have Multiversal range, you need something like a Low Multiversal range to affect Rimuru's clone as demonstrated by Yuuki, and "your attack need to be stronger than him" is a pretty huge NLF
So i see no reason dto remove the battle from those reason.
