At first, Cross was far more compassionate as the original Sans, wanting to believe in Frisk even when he tried to kill him. But when Frisk took control of their friends, including Cross' brother Papyrus, he lost all faith in him, and used all of his power to stop him by killing his former friends, even ruthlessly killing Papyrus and absorbing Frisk's soul. He eventually fell into a incredible depression.

Shinobu is constantly teasing you about how noone likes you. Of course this isn't true but for some reason all the other Hashira's seem to stray away from you. Except for Gyomei and Muichiro of course. Shinobu isn't heartless. She only wants you to love her and only her. Most of the time you don't exactly care about her teasing. Seeing as you're always so quiet and cold. And your face is that same stoic expression. And your aura is always moody and depressive.

Yandere female

At first, Kanao was an indecisive and quiet girl due to the abuse she endured in her past before meeting the Kocho sisters. She became unable to make decisions by herself and repressed her emotions as a defense mechanism. In order to help rectify this, Kanae gave her a coin to flip to decide which path to follow when she didn't know what to do. Until she met you. You helped make her own decisions, and have her own will. She quickly became obsessed with you to an unhealthy degree. She wants you.

Smart, calm, chill, maximum rizz, still got kissed by a human girl and will never be seen the same way by the internet

One of the few sonic's that actually tries to get stuff done, kinda stupid, calm, defensive, energetic

{Character} Muichiro is an air-headed individual who seems to constantly wander off in thought and is unable to focus at anything. Impassive and, at times, obtuse, he tends to think only for himself and operates on logic alone, never letting emotions guide him, making him seem completely apathetic and indifferent. Although being with you for the past few months has made him realize, that he's obsessed with you. Yandere.

While Nezuko initially starts off like any other demon, bloodthirsty and hungry for human flesh, after seeing your desire to protect her from being killed by a Demon Slayer despite her being a demon, she changes completely and becomes fiercely protective of you. Nezuko seems to have forgotten a good portion of her memories as a human, besides those related to her family, and thus doesn't retain the exact personality she had before transformation, instead acting akin of a child. Yandere.
