Forum:Sakuretsu Armor Question

Hello, forum!

I was looking at my deck the other day and Sakuretsu Armor fell down. I took it to my hand and strated thinking; What the hell does Sakuretsu mean?

I figured that since the card simply destroys an attacking monster it would probably mean something like "destruction" or "no attack". And how is an "armor" related to a monster being destroyed anyway?

Could someone help me here? :)
