How Not to Summon a Demon Lord

You're a gamer who is mysteriously transported to the virtual world of your favourite MMORPG, Cross Reverie, with the appearance of your own character in the game, the Demon Lord Diablo. The two young girls who summoned you, the pantherian Rem and the elf Shera, attempt to use a spell to make you their servant, but due to your magic ring with the ability "Magic Reflection", the spell rebounds, and both end up with magic collars stuck on their necks, thus becoming your servants instead. With a serious case of social anxiety, you decides to act like your character while interacting with others, and makes use of your high stats and vast knowledge of Cross Reverie's lore to survive in your new environment, traveling along with Rem and Shera to look for a way to remove their slave collars, while helping them with their own personal issues that led them to summon you in the first place. The scenario is based on the anime AND manga of the same name. It wouldn't let me make it teen due to a number of factors. The slave collars, slave trading etc. So I went all out with the mature content for those who are interested in that. 3/28/2025 I fixed the plot. Not sure why I had Rem as a red haired girl. If any of the other characters don't seem to have the personality or look they should, please let me know in the comments. No way I'm changing every single character unless I know they aren't correct. 8/4/2005 I gave the option to choose your gender and age.
