Случайно наткнулась - оказывается, в английском словаре современного сленга (Urban Dictionary) есть слово "Зангетсу".
И к нему даже целых два объяснения. Очень интересно их сравнивать - хороший пример, как можно сказать одно и то же по сути, но в совершенно разном стиле...
1. Badass sword owned by the one and only Kurosaki Ichigo from Bleach. In its shikai form the sword looks kind of like a giant butcher knife. In its bankai form it's a long, black katana. And its persona is that of a scruffy-looking man in black who is TOO BADASS TO ACCURATELY PUT INTO WORDS.
2. Zangetsu is the zanpakutou of Ichigo Kurosaki. In its shikai(initial release)form it looks like a giant cleaver. Its bankai (final release)form is a black katana or nodachi with a handguard in the shape of the manji.The materialized form of Zangetsu appears to be a middle-aged man with middle length black hair wearing black cape.
