BLUE BUNSHIN is a zine collection of Filipino poems by Marius Black, composed between 2014 and 2015. "Bunshin" is the Japanese word for a branch, clone, or alter ego. In this series of poems, Marius collects all the poetry he made for the women he was then pursuing.

From the girls he secretly liked, to women he went out with and courted or broke up with, or from past relationships or women who dumped him, poetry even for women he never even spoke to but felt a connection with. These are all poems of adoration, love, lust, and some erotic, all of which are in service of his search for "the one," which, by the release of the zine, he was able to find.

The zine’s twin is PINK BUNSHIN, which is another collection of poems in English with the same purpose. They are not, however, translations of the poetry in PINK BUNSHIN but are instead another 30 different poems written in the language.
