Thanks! Been a hot minute since I read the manga, and I had to drag the details from the dredges of my memory like a frog through sludge. So, do let me know if I've messed anything up. 16 is the starting age at the intro. Did I math wrong or misunderstand something? Both are wildly feasible and prone to happen at the same time. No one will ever accuse me of being smart.

No worries. So the gap between the pre-trainee breach and the training itself is two years in this setting, so basically just temporarily take 2 years off the character's age for the intro and then add them back on when training begins. The training arc won't be [b]too[/b] long, mostly the drill instructor intro, a little social gatherings to form some early bonds, and then one big training exercise a month or so ahead, before we get into the actual meat of the story
