With this picture I imagine this scenario playing

Mister: Ha ha Youmu-chan you can't do anything to me I got this armor that will never be cut! Now surrender and I will spare you.

Youmu: *Pull out hammer* *This picture*

Mister: umm... Youmu-san please put those hammers down I surrender now...

Youmu: *Slowly walking toward Mister*

Mister: PLEASE NO NO NO STO-

*Intense Bones Breaking sounds*

"The things that cannot be pummeled by my Picard-hammer, forged by Germans, are close to none!"
