When I came to, I found myself lying beneath a silent ruin. Countless powerful creatures hailed me as a Demon God and declared their intention to destroy the entire multiverse.
To my surprise, these terrifying underlings who recognized me as their master were the very creatures summoned from Yu-Gi-Oh! cards: the beautiful Traptrix girls, the Spellcaster girl, Five-Headed Dragon... and more. Wait, it seems there's more to it than that. Why is there a pile of Yu-Gi-Oh! cards beside me?
All right, all right. This is really a story about a Demon God awakening and conquering worlds across the multiverse (planes), in an Overlord-style setting.
P.S. Gender-bending, with light yuri.
