Serio is a solemn oath of absolute truth and loyalty used among close friends — a verbal contract that what you’re saying is real and must be believed. Serio 10 is the elevated, unbreakable version of that oath. It’s the equivalent of saying “I swear to God,” but on a deeper, more sacred level — a level 10 declaration of truth that cannot be taken lightly.
Once “Serio 10” is invoked, the statement must be 100% true — no exaggeration, no trolling, no lies. Breaking a Serio 10 is considered “abuse”, and doing so severely damages your credibility within the group.
Breaking it once leads to a loss of trust. Repeated violations result in social devaluation, exclusion, and eventual ostracization. Within this code, Serio 10 is sacred — if you use it, you better mean it.
Think of it as a verbal blood pact. You either honor it, or you’re done.

B: “Alright then. I believe you.”
