Well, her ability is weird in some way since Ren can't cancel it, she's superhumanly strong to the point she can manhandle Peach users whose ability actually is just super strength, and she can cut Shuuki despite that supposedly requiring a Peach blessing, even being noted to be the only one able to do as such. Also she grew up in a secret village

The author could totally take that route if they wished, which would be kinda neat

Didn't she literally cut a full power god's fingers off in the latest chapter without Yuuki's help? That girl is absolutely not human.

I think there got to be some hidden aspect of Kyouka's Eternal Chain ability.

Like when a slave dies, some percentage of it's base power gets transferred to Kyouka, meaning all those Shuuki slave that Kyouka had before Yuuki gave some of their powers after they died.

Another possibility is that, there is some correlation between Slave's Power and her own Power, like sharing some base stats or something.
I mean, before she had trouble cutting a large Shuuki (created by Shikoku), but suddenly now she is able to cut a God.
There was also her fight with Unihorn, in which when she fought it solo, she didn't really do much damage to it, but once Yuuki joined and transformed, she suddenly started to cut Unihorn up.

Oh, they got a poll up and running.

Interested to see who's at the best overall.

Kyouka got the anime boost. Unbelievable, she smashed Tenka and Ren
