"Mini Tournament"

Can the mimicry ability users copy the soul oath sign too? 

Grandpa Yofan took a deep breath and sighed. 

"Only a small percentage of these ability users can mimic the soul oath that bound the subordinates to the bosses. So...you don't need to worry about this." 

Actually, the reason why all important people in the mafia family needed to swear an oath that would tie their soul and life was because of the possibility of someone impersonating them. 

It's scarce for mimicry ability users to be able to copy the soul oath too, that's why it's hard to sneak into the family as a spy. 

However...it didn't mean they couldn't sneak into the family through the normal members. 

"Ain, our family never have spies or find spies in the rank so far because we are just a worthless family. But now that we are rising fast…" 

Grandpa Yofan shook his head.
