35 том

[W0WC00L]

Помогите с переводом!
Одну страничку немогу осилить, какая-то каша получается, никак не пойму о чём там Ода сенсей говорит в вступлении тома.

There is a theory known as "Nanba-walking." It says that pre-Meiji Japanese used to walk by extending their right arm with their right leg, left with left. This makes me think that ancient Japanese were very nervous people. The reason they were nervous was of course, because their secret crush Mariko would be attending tomorrow's piano recital. When your fingers are too short to reach the black keys well, you need a plan to conquer this weakness, which is why today they will hike into the mountains to fight a bear!!

Первые 2 предложения понятно, а вот дальше... Что за Марико? Древние японцы и пианино? Причём короткие пальцы и борьба с медведем? оО
