Just curious, Narg, but have you played Suikoden Tierkreis? If not, I reccomend it, especially since I’m sure you’ll enjoy one particular chapter in the game
There seems to be a pretty good support of twincest when it comes to Chrodechild and Fredegund. First, they’re probably the best physical fighters in the game and they both have a powerful attack unique only to the two of them (True Falcon) that put together makes for a pretty good boss killer. They each seem pretty happy when you put them in the same party, they shield each other if one’s HP is low, and they get enraged when one of them is knocked out.
Also, while this game like the other Suikodens (except 5) is pretty ambiguous about possible romantic pairings with the hero, conversations seem to imply that Chrodechild might like the hero (of course that would mean competition with Asad) and Fredegund doesn’t seem to mind the two of them being close (whilst in Asad’s case, he mentions that the biggest obstacle in getting close to Chrodechild could be Fredegund). Twincest possibilities?
