Synopsis

Takuma Sakamoto is a hikikomori gamer who never leaves his room until one day he is suddenly transported into his favorite MMORPG, Cross Reverie, as his character Demon Lord Diablo! Turns out he has been summoned by pantherian Rem and elf Shera who wish to make him their slave, but thanks to his passive ability “Magic Reflection,” the spell backfires and they end up his slaves instead! To compensate for his social anxiety, he decides to roleplay as Diablo while using his knowledge of the game and ridiculously high stats to survive in this dangerous world while traveling alongside Rem and Shera and making a name for himself as the “Demon Lord from another world.”
