I Reincarnated as My SSS-Rarity Female Necromancer Character from the MMO Dungeon Fantasy Online

A programmer relentlessly exploited by his company. He died from overwork, frantically pressing keys to finish the code he'd been assigned to improve at the last minute. His karma was pretty negative. He'd committed several deadly sins, especially being a sexist. As punishment, he was reincarnated as a woman. But he awoke inside his own MMO character. "Wait...! I have boobs and the Necromancer Girl System has activated!" Now he's Saera, an SSS rarity necromancer in a peaceful world... and a System that demands he generate absolute chaos or face brutal penalties. What to expect:  Character progression / Gender Bender / System / Necromancy / Chaos generation / Fantasy / LitRPG / Dark magic / Dark humor / Isekai / Multiple races / Fantastic creatures / No NTR.
