That's exactly what I thought ! (๑•ㅂ•)و✧
Lol you read my mine ⁄(⁄ ⁄·⁄ω⁄·⁄ ⁄)⁄
that was also the idea i had from the first chapter on, and looking at the latest chapter, I think we are right ^^
yeap, I think that must be it
Rather than that, I think her sin is making the Son of Yama fall for her ╮(￣▽￣)╭
I've been thinking the same thing for a while now. But maybe also all the brothers fall for her and they fight over her, causing a ruckus and that's her sin. (￣ε(#￣)Σ
I feel the chapters are pointing more and more towards that..:)
I bet her sin is for falling in love with a son of Yama. but that's only my guess (=・ω・=)
