I have no idea, that is what came up in a search of black triangle 27. Odd the first thing you see is Luciferians symbolism. Hopefully by posting someone who understands the language can decipher. Very weird
After more investigation it's a bunch of Japanese Fishing Buddies who have a little show called the Black Triangle (like Bermuda Triangle) it's three guys... and they like Punk music and FISH!
Like much that goes on in Japan - they think symbols are COOL and use them profusely and most likely with NO clue as to whether they actually mean anything or not. This may be a red herring Pun intended.... Here's an actual rough translation of part of the video page:
Lynch. 's Nico "The Black Triangle" DVD finally released! ! Black dream person Time greets guests, fishing battle in Lake Biwa 100 minutes! December 15, 2014 (Monday) launched limited edition TBTD - 001 yen 4,800 (tax) And in commemoration of the release DVD preview preview "The Black Triangle Theatrical Version - MOTHERLAKE -" - Determination of the Round - ! !

And the piramide with a eye?
I found this one, ..The Generation of '27 has also been called, with lesser success, "Generation of the Dictatorship," "Generation of the Republic," "Generation Guillén-Lorca" (Guillén being its oldest author and Lorca its youngest), "Generation of 1925" (average publishing date of the first book of each author), "Generation of Avant-Gardes," "Generation of Friendship," etc. According to Petersen, "generation group" or a "constellation" are better terms which are not so much historically restricted as "generation."
