i recommend the WN translation. it's finished, and it probably won't take you 8 years to read it.
also, kouhai is a lot cuter in the WN, and the banter is wittier.
the manga is a little too over the top IMO, with such a cartoony style, so it loses a bit of its charm and wit.
baiting for future plot drops, most likely. that's hata's M.O.
drop some bait, troll readers, readers forget, troll them again, readers forget, lather rinse, repeat.
You haven't seen my basement. 😬🤣
It is speculation for fun, of course, but if you think in terms of basic developmental physiology or neurophysiology, children's brains aren't capable of the same things that adult brains are capable of, because they're still developing. If you think about how...
Physiologically, this makes sense. If an adult's "consciousness" were crammed into the brain of a much younger child, the child's physiology would naturally have a great impact on that adult "person's" perception of the world, their emotional/mental health, etc.
It's kind of like trying to jam...
