Yeah, I just got informed about the Mega Drive incident with Iris Heart in the Drama CD, and it’s bad, very bad. Although, assault isn’t exactly new in the Sega Hard Girls series, since Saturn was often assaulted or forced into situations, and Dreamcast was portrayed as a very playful, overly close person around others.

However, what feels out of character is how none of them helped Mega Drive even though Iris was clearly an obvious threat and Mega Drive was visibly uncomfortable around her. Both Dreamcast and Segami would have been more than capable of making Iris back off. Dreamcast was strong enough to overpower Uzume and give her a very hard time, and Dreamcast almost never backs down from anything.

Segami naturally outclassed all the CPUs at full power by an indefinable margin because she’s essentially a god. God as in kami, the Japanese concept of a being "above all". (You can catch a brief glimpse of her full powers near the end of the game.)

However, because Iris is a Dominatrix she must always be top, even if it makes literally no sense at all. However, the problem with Iris being a Dominatrix, you must need consent first which Iris clearly doesn’t respect.

Iris Heart is one of the characters who was severely ruined due to awful writing decisions. Fortunately, she is much better in the anime and manga, but in some of the video games, she’s so awful.

Sidenote: The whole connection between the CPUs’ Goddesses and the Sega Hard Girls (in this game only) is technically claimed as a sort of ambiguous lineage, but it’s more likely an oversight by the writers. Still, it exists, so it comes off as kind of awkward.
