Select a new birth date day since the page says 44 and there are only 35 days in each of the 9 months on the Yamataian calendar.
Clarify the year he joined the Star Army of Yamatai
Note: Claustrophobia could cause him to fail basic training if severe, remember they're all some level of astronaut
The minimum age to join the Star Army for most people is 21. Synthetic life can be accepted earlier if they're both physically and mentally equivalent of 21. Basically everyone has to be an adult. I am not clear on if he was created as an adult or not.
If he is looking for a job, you can go to the Candy Fest Open RP and interact with my character there. She is at a booth shamelessly handing out free candy to then expose people to working corporate. Just like US military recruiters. Lol
