The plot is that the titular healer is a 14 year old boy that gets raped and tortured by the 17 year old princess of the kingdom for 4 years. Then he learns a spell to go back in time so he can rape the girl that raped him, brainwash her, and make her his sex slave.
It's disgusting and says a lot if it's Nick's favorite anime.
Nick's favorite anime is Redo Of Healer, infamously known for child rape and sex slavery.
Nick's favorite movie is American Beauty, thematic of an adult man infatuated with sex with an underage girl.
Nick's favorite porn stars--to which in his own words he openly proclaimed to be an expert in--are the young petite pubescent types.
Nick's own friend Drex told the story of how he groomed a teenager into BDSM sex, for years. Nick offered no push back, and was clearly amused by this story.
Nick's known associates today are all (perhaps with the exception of Camelot331) known creeps with histories of child or spousal abuse. Melton, Ralph, Dax, etc.
Nick's actions show a motive to lie and manipulate women into being compliant to his every wish. Nick screams at women who don't comply.
Nick's own admission is that he introduced April to cocaine, molly, ketamine, and whippits. April says he emotionally abused her.
Nick's own daughter tested positive for cocaine exposure, at a level of frequent user--an alarmingly common indicator for being groomed toward sexual abuse.
