WN: Lillia's village was attacked by bandits and her mother Maria hid her in a closet. She was then found by an evil knight and held captive when she was a little girl. Confinement, Torture, R*pe, Gore, Human Experiments. Then she was rescued by a holy knight named Margaret who uses magic to erase Lillia's memories to become Maria. her new village is attacked by monsters and her mother Margaret is killed, so Maria becomes an avenger to kill monsters. Maria/Lillia's oppressor shows up again, but is taken care of by Fei who cuts his arms off and slashes his eyes to permanently blind him. The rest of events afterward more or less follow the LN.

LN: Lillia's village was attacked by hypnotized monsters by a mad scientist lady named Terror. Her mother Maria also hid her in a closet, but she was discovered by Terror. Confinement, Torture, and Human Experiments. Then she was rescued by a holy knight named Margaret who uses magic to erase Lillia's memories to become Maria. her new village is attacked by monsters and her mother Margaret is killed, so Maria becomes an avenger to kill monsters. Terror shows up again to kidnap Maria, but gets her eyes slashed and arms cut by Fei, then smashed her head onto the floor creating cracks. Fei avoiding killing her due to the possibility of the orphanage kids being traumatized.

Analysis: Due to this she has dual personalities of Lillia (young village girl) and Maria (former swordswoman and sister). Maria/Lillia's oppressor shows up again, but is taken care by Fei who cuts Terror's limbs off and slashes her eyes. Fei gives Maria two hair ornaments (red and blue) to symbolize the dual personality. As a result, Lillia's ego does not disappear and both personalities co-exist while Fei acts like a stabilizer for them. Maria worries about her age and age gap at times, but Lillia vows to never to give up on Fei and is the most aggressive romantically of the two. Maria wears the red hair ornament when she is in control, whereas Lillia wears the blue hair ornament when she is in control. If Fei gives them a single gift, then Maria and Lillia will fight over it.

Interestingly enough if you average the mental ages of Maria (25) and Lillia (14~), you get Fei's age although he is a reincarnator so his actual mental age is much higher than both combined. In the original novel setting, Lillia's ego disappears and Maria is the only ego left, so her romance route is effectively a dead end.

Removing the r*ape from the LN version was probably for the the best because as other commentators have said, r*pe is a an easy way to get shock value from readers and moreover it is too overkill when you add confinement, gore, torture, human experiments to the mix. It tilts the novel too dark and makes Maria the undisputed tragic heroine in a harem genre.

Yururu (23) - Fei's swordsmanship teacher in Namikaze style. He risked his life to save her from being exiled. He treats her love gestures as hints and foreshadowing for future trials (lol). Former noble lady. She has withdrawal symptoms if she does not see Fei for a long time. Fei's 2nd heroine.

Mei (21~) - Yururu's former maid in the noble house. She is similar to Fei in that they both think they are protagonists. Mei thinks of herself as a protagonist in a romance novel and has vivid fantasies about herself and Rei.

Arthur (17) - the koala panda rival character for Rei. Self-proclaimed girl friend/expert on Rei due to her love. Although she is very bad at communication so Rei often sees her like a panda-like rival (reference to Ranma 1/2). She is very bad at naming things like naming Fei's skills like Snake Attack and Fei Punch.

Mordred (17~) - the violent heroine for Rei. Has an obsession for Rei due to his avenger type of fighting style and muscles. She sleeps naked. Former oujo-sama and uses desuwa verbal tics. Can only see the color red vividly and likes spicy food. Teaches Aliceia swordsmanship. First Yandere.

Aliceia (14) - True's blood related younger sister in a side story event. Alicia tags along with Rei in the dungeons and becomes attached. Outsiders think of their relationship like a stoic older brother and their clingy younger sister. Rei saved her a couple times. Her nickname is haunting ghost for following Rei around. Becomes yandere towards the end and is corrupted by Mordred's muscle fetish. A very good cook and teaches Mordred cooking. Second yandere.

Bowlan (15-16) - half-human and half beastkin born from a human mother and beastkin father. She was exiled from her beastkin village after her parents died and left to die in the wilderness. She was initially stuck up in the first volume, but after some time she cooled down and is quite friendly. Bowlan falls for him after Rei defeats her father and beastkin woman like strong males.

Alpha, Beta, Gamma (16~) - triplet sisters who think Rei might be an avenger like them. Rei saved Beta from a drunkard and left without a word, so Beta has a bit of a crush.

Barbara (20~) - the Guild leader of Romeo Guild in Free City. Slowly becomes attracted to Rei since he is an idealized form of hero that her father pursued. Calls Fei Fu-chan and tends to give people she likes nicknames.

Heimi (14) - A village girl that Rei saved from a villain with evil eyes. Rei protected her dignity (she wet herself and Rei carried her on his back to hide it until she was inside her home). She vowed to become a knight like him. Potential first kouhai for Rei.
