How Not To Summon A Demon Lord Vol. 2 (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. 2, using his skills as a powerful sorcerer, Diablo is able to protect the town of Faltra from being invaded by the Fallen. However, the peace they brought to the town doesn’t last long. When the Kingdom of Greenwood, the country of Elves where Shera is from, demands that Shera be returned or they will declare war, it’s up to Diablo and the others to find a way to stop it! But what will it mean for Shera?
