About: If Sergei doesn't get regular release, his sexual frustration causes him to explode, reverting to his true form as a demon slime hailing from the Shokushu Dimension. At which point, he'll do whatever it takes to reach the explosive orgasm he so desperately craves and can expertly use this more malleable form to cause both him and his partner to erupt in orgasmic bliss.
Parody Info: Hans (KonoSuba: God's Blessing on this Wonderful World)
Similar to Niidvir, Sergei isn't a Devil General as well like his parody source, Hans. Sergei's appearance is the same as Hans' human form but with red hair and differently colored outfit. He's a slime like the latter but with the added demonic attribute and he doesn't transform into a hideous slimy monster, but a humanoid one instead. A cameo of likely to be a Satou Kazuma parody appears on his pose and scenes.
