GUMIN DAYS is a Label that specializes in the niches, the absurdity, and the soul of Otaku culture.
GUMIN DAYS is a Label that specializes in the niches, the absurdity, and the soul of Otaku culture. Separated loosely into arcs with some independent character stories, GUMIN is best enjoyed with the lens of it being an earnest love letter to the anime and hobby culture that Japan has cultivated over the years.
We recommend reading GUMIN for Otaku in general, people that love anime and its assorted classic tropes, and comedy that suspends disbelief.
GUMIN stories, especially starting in CHUNITHM CRYSTAL, are full of esoteric references to Otaku culture, pop culture, and even beyond. Dedicated fans on the Japanese wiki have created lists of references and their meanings to each applicable character story. It's worth noting that since GUMIN pulls from Japanese culture so heavily, some things may be untranslatable, or not make sense to a non-otaku audience.
Since GUMIN DAYS is lower on our translation priorities, and fully translating every character is out of our scope, expect updates to be very infrequent.
(If you're interested in contributing translations to help us, please check here!)
Characters with active pages/translations will have their names bolded and underlined.

A world domination movement is started by Yuria Onimamushi to convert everyone into Otaku, starting with the city of Tokyo. The story culminates in Akihabara rising into the air, where the Tokyo idols face off against a trio of resurrected idols from the Edo period who aim to brainwash the masses into Otaku.
