The Eromanga Sensei meme stems from the 2017 anime adaptation of Tsukasa Fushimi's light novel series. It revolves around Sagiri Izumi, a hikikomori who secretly illustrates erotic light novels under a pseudonym. The meme usually highlights the 'trash' nature of the show's premise or uses Sagiri's highly expressive and often grumpy facial expressions to convey annoyance, secrecy, or the relatable struggles of being an artist. Within the anime community, the template is frequently used to mock controversial tropes or to celebrate the absurdity of the 'little sister' genre in modern Japanese media.
