What? ! Have I traveled through time? !
Okay, just wear it, but why am I not the protagonist? !

"... I'm not the protagonist either."
"What does that matter? Anyway, you are the protagonist's father, and you also have the aura of being the protagonist's family member."
"... What is that?"
"You don't have to worry about what kind of boss that is. You just need to know that I am a super competent little brother who can kill enemies when I get in and warm the bed when I get out. O(≧v≦)o~~"
