I know it's a game but i couldn't help but think, why doesn't Aura deal with Richard in the normal world. Like they are far more equal in terms of power (especially with... a gun!), she knows where he will be and when, and has an easy way to isolate him. Just go down to Walmart, buy a gun, improvise a silencer, have Richard meet her at an isolated local to surrender, three rounds in the chest and one in the head, incinerate everything you had on at the time and smelt down the gun. Plenty of time to prepare and all, she's quite studious, could probably get away with murder. Look Alicia in the eye, "Be a shame if another bully disappeared...". Needs to read/watch more murder mysteries, less isekais.
If you've ever read the First Law series by Abercrombie, need a Sand dan Glockta, inquisitor and torturer, to come visit Richard. My favorite character in any book to date.
Back on focus, I think I may have to just concede the game isn't for me. NTR has never been too liked a thing to me, I'd just rather they properly talk with their partner and explore a poly component. Maybe do all those things with your partner first if you are some adventurer fighting rapey monsters or whatever. The corruption is a bit too thorough, it's really the isolation of her friends and going from selfless to selfish that gets me. A shame I hadn't gotten to the vice system yet, seems like a fun one to explore, vices of drinking, stealing, gambling, etc.
