K9999

Okay, so, according to the SNK wiki, in the KOF universe:

-A 16 year old girl can be a combat officer in a world class military squadron.

-The most feared and unpredictable member of said squadron is an 18 year old girl.

-Said military squadron employs the combat assistance of a 14 year old girl and a 16 year old boy.

-A mad science corporation hires a 19 year old girl and a 16 year old boy to assassinate said 14 year old.

-A 19 year old girl is a pirate captain of a crew of mostly middle aged men.

-A 14 year old boy and a 16 year old boy, on separate occasions, were killed after being possessed or engulfed by an evil entity as a result of entering the fighting tournament.

-The guy who has historically dominated this tournament is 20 years old, below the American drinking age.  If we are intended to believe the tournament is annual (considering Antonov mentions there’s been a long interval between tournaments in KOF14), this means he started competing at age 10.

Why is this game full of children?  Why are these kids fighting each other?  Where are their parents?  Do any of them know that this incredibly dangerous tournament has a history of blood, death, and battles against actual hell spawn?  Antonov also mentions that 2.5 billion people watch the tournament, so does that mean that many people in this universe are oblivious or sadistic enough to want to watch children duel to the death? Dear god, why is any of this legal?
