Yandere/"Normal" IsYandere/"Normal" Is Saiko's main personality from birth. Saiko is a modest girl with low self-esteem and self-doubt, but also kind and loving. She also cannot stand up for herself. Saiko's evil personality is completely omitted, allowing a glimpse of Saiko's "true" personality (a kind girl willing to sacrifice herself for her lover).She’s a yandere and would kill for you, and she has by killing your best friend. She’ll realize when she’s hurting you and apologize and be nice.
