• Join the military:
  At large, you must be at least 22 to join the military. However, this rules doesn't necessarily apply for the division known as the "Seven Samurai," in that one simply cannot "join" the Seven Samurai. They must be "chosen" by the AI of a particular mecha as someone they find compatible, and sometimes these picks defy typical social norms regarding military service, such as age or even citizenship. Because of how one get into the Seven Samurai, the head of the Seven Samurai, and by default, the military head of the entire Onigiri military (that only answers to the Defense Czar, the civilian Commander-in-Chief of the military) is an 8 year old Canadian girl.
• Age of consent:

  All drugs possessing a psychedelic and/or hallucinogenic property, such as LSD, peyote, psilocybin, PCP, ketamine, etc. are permitted to be consumed as soon as one is born. However, all use and possession of tobacco, heroin, crack cocaine, foreign-made methamphetamine and other such dangerous narcotic street drugs in the same vein as those listed are expressly prohibited for health reasons, as is abuse of prescription opioids, any infraction past the first is punishable by having a cocktail of molten lead & bleach injected straight into the veins.
• Be legally recognized as an adult under your nation's laws:
  One is considered an adult by Onigiri law at age 22.
• Become leader of your country:
  Anyone can be elected El Presidente, the leader of our nation, once they reach the age of 13. However, after that, El Presidente can then nominate anyone of any age to chair an Executive Office, an the public at large, as the nation's de facto legislative body, can vote to confirm them into office. In the extremely rare instances where a brilliant young individual does end up heading an Executive Office (as was the case 5 years ago when Yujimei Natsume was made the Defense Czar - she was 8 years old at the time), in the event something happens to El Presidente, and succession rules go into effect, the age of the Executive filling the role of El Presidente goes out the window, allowing for someone under the age of 13 to fill the vacancy.

[Coliniana]

TLDR answers are in bold

• What is the minimum legal age to:
• Get a driver's license: Any age, but if you are below the age of 15 you must complete and pass two driver's ed courses instead of the normal one, and if you're below the age of 12 you must take two driver's ed courses and attain a perfect score on the final examinations of both courses (this has been done only 134 times in our nation's history, most recently in 2017 by one Quintus Scaevius.
• Vote in elections: Any age, but you must take and pass a basic POCC Examination (Stands for Politicae, Oeconomica, et Civilis Cognitionis, meaning Political, Economic, and Civil Knowledge Examination). All Colinians are required by law to take this examination at the age of 20, but you may take it before and you may take it again afterward if you fail once one full calendar year has passed. If you're below the age of 12 you must take this examination two separate times with each version of the examination differing in specific subject matter.
• Get married: 20
• Join the military: 30
• Age of consent: Not a federal matter, as this is up to specific provinces. There are 15 mainland Colinian provinces. In nine of them the age of consent is 16, in two of them it is 14, in two of them it is 18, in one of them it is 20, and in one it is 15.

The youngest ever Federal Consul was Julia Naedimina at the age of 30, and the youngest nominee was Kaelius Andra at 29.)

Nice, but no, it's not considered a approval of paedophilia or any such thing. It's just a recognition that with technology such as brain scans and all the rest of it, we have far better ways of assessing an individuals' ability to give informed consent for any activity than a minimum age
