Once more, thank you very much, Nagoyankee.
I was looking for this explanation "In the order of informality: メタメタ　＜　メチャメチャ　＜　滅茶苦茶（めちゃく ちゃ）".
I had just found "mecha-mecha" before you teach me.
I got surprised with "Yakuza" for the "ninkyô" too. Even the text uses "oyabun", I never imagined "Yakuza" would synthesize chivalry – when I read I thought "ninkyô" was "heroes", but "Yakuza" are bandits, no?
Thank you very much, Nagoyankee.
