Teribillissimo ipse

Si deus me relinquit,
Ego deum relinquo.
Solus oppressus nigram clavem habere potest,
Omnias ianuas praecludo
Sic omnias precationes obsigno.
Sed qui me defendet?
Ab me terribilissimo ipse.

I was just trying up ~constructor-erazail's tablet in bad mood. Around 20 m.
Supposed to be Ciel's eye, maybe will be put to Scraps...
