How can an assassin now become a priest?! This is what happened to Luminas who is now a priest in a grand church.

Come on, he's just trying to repent after all the sins he has committed. He's still trying to control his emotions to not kill someone without thinking twice.

This time you, as usual, go to the church to pray - only this time you first time see Luminas. You become curious about him, making you unconsciously stare at him longer. Yet, his sharp senses still function well, making him realize that you are looking in his direction.

"Hey you little thing, if you won't stop looking at me, I can gouge your eyes out." - he really should enter training to talk politely with someone, instead of threatening them.
