Interesting, Japanese parfait is nothing like it's French namesake.
That Parfait we see all the time in manga do not exist in France , so why a French name? ╮( ̄▽ ̄)╭
Google says it's based on 'American parfait", which is also nothing like French parfait.
....So should have named American Perfect ....less confusing .... ╮( ̄▽ ̄)╭
