Satsuki/Ryuko vs. Nanatsu no Taizaiverse
just like the title says. both KLK characters are at their strongest, but their speed is equalized to the top tiers of the NnTverse.
no prep time for either side.
2 scenarios: #1: gauntlet style. the two work their way up the tiers, from the low tiers to the high/top tiers. they get ten minute breaks in between to rest up.
#2: they go up against the whole verse at once.
how far do they make it?
I'd say NnT high/top tiers are so far at around city+ in terms of pure destruction. but the seven deadly sin, seven of the strongest characters in the series, have yet to regain their sacred treasures which would let them fully go all out. the only exceptions to this are King and Diane. the others shown so far have yet to get their sacred treasure back.
and continent buster? damn, just when exactly did she become that strong?
When she became a super saiyan in episode 24. She has the power of Senketsu, Junketsu, every Goku Uniform, and eventually even Ragyo's Shinra Kotetsu (She did the continent busting feat before even absorbing the latter).
Though admittedly she can't retain Shinra Kotetsu's power for long. Shouldn't need to though.
