After three years of self-imposed isolation from society, Otaku Jinkyung's only companions were his 2D friends. Unexpectedly, a small summoner from another world sought his help. Jinkyung had become a shut-in otaku due to being labeled as a "child predator" on live TV resulting from a misused word joke, which led to his battle with social anxiety disorder. The summoning to the new world, however, caused his anxiety to dissipate, revealing his immense power as the most potent summoned being ever. Thus, the story of a powerful 2D otaku and a feeble summoner commences.
