I also noticed Ayase only getting smaller & Kanou bigger, & all other characters bigger [but not s big as Kanou]. Tho small people exist so I'm just going with Ayase has proportionate dwarfism sydrome or Human Growth Hormone (rhGH) Deficiency [also explains why he has a sick frail body all the time] or some other small stature disorder. ╮(￣▽￣)╭
That is a good way to look at it, because - as it is - it is a little too shotacon atm. I guess some people don't like thinking about the size difference and thumbed me down. Ah, well!
Ayase keeps getting smaller, now he is about as tall as a seven year old boy, it is getting rather silly. Might just decide to give this a pass from now on. Maybe ╮(￣▽￣)╭
