Saiko Chan seems like the type of person to occasionally hop and skip in her steps when she chase you or looks around in the hall. Because she is enjoying killing you soo much. She also seems like the excited type to suddenly surprise jump into a class room, or say, "BOO!! Hehehehe :3" when you meet near a corner or stare.
I REALLY REALLY love her! She's suuuch a great killer because of how much detail you've added to make her have lots of character. I honestly want more realistic characters that bring out her character more.
Like for example, if she was to throw the knife at you as you are at the end of hallway, and you had to pull it out shoulder to prevent from being slowed.
