How Not to Summon a Demon Lord – When Social Anxiety Meets Unlimited Power

There's something deeply relatable about a protagonist whose solution to being summoned to a fantasy world is "just keep pretending to be scary." Takuma Sakamoto built the ultimate character in his favourite MMORPG, then woke up inside that character's body — stats, horns, and all. The catch? Two summoners tried to enslave him, the spell backfired, and now he's stuck with two devoted companions while desperately maintaining his demon lord persona because breaking character would require actual social skills. Our How Not to Summon a Demon Lord merchandise celebrates this glorious disaster of an isekai setup.
