Hey potato, after the timeskip... I dunno if this would be too powerful, but could Light learn Shatter Reality?

Shatter Reality (Light's lvl 3 hyper combo basically)

Light grabs onto an opponent and shatters reality around her, turning everything near her (5m) into cartoons temporarily. things affected by Shatter Reality lose their reality extremely fast when touching Light. Not touching Light for a minute will cancel the effect of Shatter Reality. 

I dunno, I wanna do an arc where its very surreal where everyone finds out where things that Light causes to lose reality and fade go. And well, Discord shenanigans.
