So Helltaker is a good cook AND good in bed. No wonder these women agreed to a harem.

Helltaker:

• notices when Modeus's tastes inexplicably change from chocolate to plum butter,
• can tell when a demon is hungry, even if she's unaware of it,
• notices Modeus started smoking,
• completely fails to realize that Modeus's skin cracked and that she has a lot of tentacles that she didn't have before. Or that Azazel is peeking and seething AF right meow.

That guy put all his points in demon psychology and perception but misses the really important stuff.

One other possibility: That's just what happens to Modeus in bed.
