-She is Chara's and Rei's little sister but is childish like Rei and serious like Chara.

-In the pacifist route she is very childish like Rei and wants to do a snowball fight where you are suppose to meet the three of them.

-In the genocide route she doesn't start a snowball fight. Cause she knows you wouldn't be nice and cheer for someone to win. So therefore you miss the snowball scene.

-In the pacifist route she'll watch the fight scene with Rei and you while smiling. She will be extremely happy with you if you don't kill her brother.

-In the genocide route. She does the same as the pacifist route but watches while crying and hugging herself sad. Then after you leaves the scene she lets Chara have the scarf instead of taking it for herself and being selfish.

-In pacifist route at the judgement hall. She'll be behind the last pillars watching you And Chara talk or Chara talk. She will smile and when you walk by her she smiles and hugs you. Saying she is extremely happy with you and lets you go after a while.

-In the genocide route she will be in a different spot she'll be behind the pillar that Chara is in front of she'll be on either side watching. When you kill Chara. She suddenly teleports where Chara was and grabbed Chara's jacket and Rei's scarf then death glare at you. Which is not suppose to be something she would do.

-In the pacifist route her theme song while you 'fight' her is Safe and Sound (Storyshift amv)

-In the genocide route her theme song changes into Vicetone Ft. Kat Nestel.

-Both routes she uses a black knife like Chara's except it has a flaming effect and feels like fire on your skin. It only takes 5 hp each hit it gets but has the burning affect and that goes down for a little while.
