How Not To Summon A Demon Lord Vol. 11 (Light Novel)

Takuma Sakamoto is a hikikomori gamer who never leaves his room until one day he is suddenly transported to another world that is just like his favorite MMORPG, Cross Reverie, as his character from the game, 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 role-play as Diablo while using his knowledge of the game and ridiculously high stats to survive. With Rem and Shera at his side, he begins traveling and making a name for himself as the “Demon Lord from another world”!
In Vol. 11, Diablo is able to find a new set of rings with Sylvie’s help (and totally not because he had a certain coupon), and visits the royal capital. But after being tangled up in a disturbance at the sorcerer’s academy, he catches the attention of the Order of Palace Knights and is taken to the king. During his audience with the king, he accepts a quest, and afterward heads south to where Rem’s hometown is. But for some reason, she doesn’t seem to be too happy about returning…
