What do you think all the boys’ true ages are?

Admin Mawile: ≡(*′▽`)っHonestly, my best guess would be that their aging process is somewhere along the lines of one physical year for every 10-20 actual years, making them somewhere between 100-400, depending on exactly what that number is. However while the Sakamakis would be naturally that old, the Mukamis are probably considerably less than that, and the Tsukinamis are probably much older. I’m really not sure how old the boys are implied to be, and this is just speculative guessing.
